Provedor de dados: 69
Autores: Montealegre,Jaime; Valderrama,Luis; Sánchez,Soledad; Herrera,Rodrigo; Besoain,Ximena; Pérez,Luz María.
Biocontrol of Rhizoctonia solani in tomatoes cultivated under greenhouse and field conditions was analyzed using the Trichoderma harzianum mutants Th650-NG7, Th11A80.1, Th12A40.1, Th12C40.1 and Th12A10.1 and ThF2-1, respectively. Their innocuousness on tomato cultivars 92.95 and Gondola (greenhouse assays), and on cultivar Fortaleza (field assays) was established. Alginate pellets (1.7 g pellets/L soil) containing c.a1 x 10(5) colony forming units (cfu)/g pellet were applied to a soil previously inoculated with R. solani at transplant (greenhouse) or to a naturally infected soil (field). Controls considered parental wild strains, a chemical fungicide and no additions. Th11A 80.1, Th12A10.1 and Th650-NG7 prevented the 100% mortality of tomato plants cv....

Biocontrol capacity of wild and mutant Trichoderma harzianum (Rifai) strains on Rhizoctonia solani 618: effect of temperature and soil type during storage
Provedor de dados: 69
Autores: Montealegre,Jaime; Valderrama,Luis; Herrera,Rodrigo; Besoaín,Ximena; Pérez,Luz M.
Wild (Th11, Th12 and Th650) and mutant (Th11A80.1, Th12A40.1, Th12C40.1 and Th650-NG7) Trichoderma harzianum strains were stored for 180 days at 5ºC or at 22ºC, in two types of soils. Strains recovered at 90, 120 and 180 days from the two types of soils, retained their full capacity to biocontrol Rhizoctonia solani 618, that produces crown and root rot of tomatoes. Recovery, estimated as colony forming units (cfu) of the wild and mutant strains, showed that all increased their cfu after storage independently of the type of soil and temperature, although kinetic behavior differed among strains. Ratios of recovery after storage in type B soil/ type A soil or at 22ºC/5ºC, higher or lower than one respectively, allowed to establish that Th11 and Th12 were the...

Molecular characterization and transcription analysis of DNA methyltransferase genes in tomato (Solanum lycopersicum)
Provedor de dados: 74
Autores: Guo,Xuhu; Xie,Qian; Li,Baoyuan; Su,Huanzhen.
Abstract DNA methylation plays an important role in plant growth and development, gene expression regulation, and maintenance of genome stability. However, only little information regarding stress-related DNA methyltransferases (MTases) genes is available in tomato. Here, we report the analysis of nine tomato MTases, which were categorized into four known subfamilies. Structural analysis suggested their DNA methylase domains are highly conserved, whereas the N-terminals are divergent. Tissue-specific analysis of these MTase genes revealed that SlCMT2, SlCMT3, and SlDRM5 were expressed higher in young leaves, while SlMET1, SlCMT4, SlDRM7, and SlDRM8 were highly expressed in immature green fruit, and their expression declined continuously with further fruit...

Harvest-Expedition on Protected Cultivation: characterization and prospective study of the challenges and solutions associated with the protected cultivation of vegetable crops
Provedor de dados: 75
Autores: Vieira,Débora de FA; Clemente,Flávia Maria VT.
ABSTRACT Farmers and the rural extension service in Planaltina, in the Federal District, an important pole of tomato and sweet pepper production in the Brazilian Midwest region, have been observing decreases in yield in protected cultivation lately. Yields are getting back to those registered in initial years of the system’s implementation in the region. Besides, prices paid to farmers dropped due to the retreat in fruit and vegetable consumption by Brazilians registered since 2015, triggering a crisis in the region. The so-called “Harvest-Expedition on Protected Cultivation” brought together Embrapa (Brazilian Agricultural Research Corporation), Emater-DF (Federal District Agency for Technical Assistance and Rural Extension) and SEAGRI-DF (State...

Provedor de dados: 75
Autores: Giordano,Leonardo de B; Boiteux,Leonardo S; Quezado-Duval,Alice M; Fonseca,Maria Esther de N; Resende,Francisco V; Reis,Ailton; González,Matías; Nascimento,Warley Marcos; Mendonça,José L.
'BRS Tospodoro' is a high lycopene tomato cultivar, which combines multiple disease resistance genes and desirable processing traits. This cultivar was found to be suitable for both conventional and organic crop systems. 'BRS Tospodoro' was obtained via backcross breeding using 'Viradoro' as recurrent parent and the inbred line 'CNPH 1306' as the donor of the Pto gene (resistance to Pseudomonas syringae pv. tomato race 0). 'BRS Tospodoro' has the Mi1-2 gene that controls resistance to root-knot nematodes (Meloidogyne incognita, M. javanica, and M. arenaria) as well as tolerance to populations of the aphid Macrosiphum euphorbiae (vector of Potyvirus species), and to whiteflies (Bemisia tabaci). 'BRS Tospodoro' has also the Sw-5b gene, which controls...

Provedor de dados: 75
Autores: Boiteux,Leonardo Silva; Oliveira,Valter Rodrigues; Silva,Cézar Honório; Makishima,Nozomu; Inoue-Nagata,Alice K; Fonseca,Maria Esther de Noronha; Giordano,Leonardo de Britto.
The number of tomato-infecting begomoviruses has increased in Brazil after the introduction of the polyphagous vector Bemisia tabaci biotype B. The Ty-1 locus, introgressed from Lycopersicon chilense, controls tolerance to species of the monopartite Tomato yellow leaf curl virus (TYLCV) complex in Europe and the Middle East. However, little information is available about the Ty-1 effectiveness against species of the bipartite Begomovirus complex occurring in Brazil. Heterozygous (Ty-1/ty-1) and homozygous (ty-1/ty-1) hybrids were evaluated for reaction to Begomovirus isolates under open field conditions in two growing areas in Central Brazil. Test plants were evaluated under natural inoculation with high vector pressure. Evaluation was done using a disease...

A field experiment on the effects of drip irrigation (DI) and subsurface drip irrigation (SDI) with saline water (6.57 dS m-1) on three tomato cultivars (Lycopersicon esculentum Mill., cvs. Rio Tinto, Rio Grande and Nemador) was carried out with the purpose to quantify physiological responses. The aim was to improve irrigation water management under saline conditions of Tunisia. The trial was established in a silt-clayey soil with three regimes of irrigation: 100 %, 85 % and 70 % of crop water requirement. Results evidenced a significant difference between the two irrigation systems for the three cultivars. Growth parameters such as leaf area, chlorophyll content and mineral composition of leaves, petioles, stems and roots were affected significantly by...

Oviposition preference of Neoleucinodes elegantalis (Guenée) (Lepidoptera: Crambidae) and rates of parasitism by Trichogramma pretiosum Riley (Hymenoptera: Trichogrammatidae) on Lycopersicon esculentum in São José de Ubá, RJ, Brazil
Provedor de dados: 82
Autores: Blackmer,Jacquelyn L.; Eiras,Alvaro E.; Souza,Claudio L. M. de.
Neoleucinodes elegantalis (Guenée) is one of the most important pests in several tomato growing regions of Brazil. The neonate larva enters the fruit shortly after eclosion, a characteristic that limits the effectiveness of insecticides and biological control agents. A better understanding of the cues that elicit or inhibit host-plant location and oviposition by N. elegantalis could lead to novel control strategies. Our findings indicate that N. elegantalis deposited 89% of its eggs on small fruits (23.1±0.95 mm), and that 76% of the eggs were placed on the first four basal fruits within the fruit cluster. The average number of eggs/egg mass was 2.9±0.17 (range 1-13), and approximately 70% of these were deposited in a single oviposition bout. The...

土壌pH と有機物施用が土壌有効態ミネラル濃度，トマトの生育，ミネラル濃度，食味に及ぼす影響について調べた。硫酸および水酸化カルシウムにより土壌pH を4～10 に調整し，化成肥料によりトマトを栽培した。また，これらのpH の土壌に堆肥とボカシ肥を合わせて施用し，トマトを栽培した。土壌の有効態ミネラル濃度は，酸性土壌においてはカリウム，カルシウム，マグネシウムは低下し，鉄，マンガンは高まった。また，アルカリ性土壌においてはマグネシウム，鉄，亜鉛，マンガンは低下した。トマトの地上部および地下部乾物重は，酸性およびアルカリ性土壌において大きく低下した。トマト体内のミネラル濃度は，酸性土壌ではカリウム，カルシウム，マグネシウムは低下し，マンガンは高まった。アルカリ性土壌では亜鉛，マンガンは低下した。トマトのミネラル吸収量は，酸性およびアルカリ性土壌においてこれら全てのミネラルが大きく低下した。果実の酸度および食味は酸性土壌では低く，pH の増加にともない高まった。有機物施用は，アルカリ性土壌において，トマトの乾物重とカリウム，カルシウム，マグネシウム，亜鉛吸収を改善した。しかし，土壌においてこれらのミネラルの有効態化は認められなかった。これより，有機物施用によるアルカリ性土壌でのトマトの生育改善は，土壌化学性への直接的な作用によるものではないと考えられる。

Provedor de dados: 87
Autores: NAQVI,S.F.; JAVAID,A.; QURESHI,M.Z.
ABSTRACT: The present study was performed to evaluate antifungal activity and GC-MS analysis of leaf extract of Chenopodium mural against Fusarium oxysporum f. sp. lycopersici (FOL), a highly problematic soil-borne pathogen of tomato. Dried leaves of C. murale were extracted with methanol for 2 weeks and after evaporating the solvent on a rotary evaporator, antifungal bioassay was carried out against FOL. All concentrations (1 to 5%) significantly reduced FOL biomass by 14-45%. The remaining methanolic extract was fractioned with n-hexane, chloroform and ethyl acetate and all these fractions were assayed for their antifungal potential. A 200 mg mL-1 concentration of various sub-fractions reduced fungal biomass significantly by 94-98% over control. All the...

Provedor de dados: 31
Autores: Sharma,   Gaurav; Singh,   S.P.
The study has examined the nature and extent of post-harvest losses in vegetable supply chain in the Kumaon division of Uttarakhand. Multistage cluster sampling has been used for selection of 80 vegetable growers, 40 farmers from the hilly region and 40 farmers from the bhabhar region. The sample has also included 25 market functionaries. Twelve major vegetables have been selected for the study. The maximum aggregate post-harvest losses have been found in tomato, followed by potato, brinjal, chilly, French bean and pea. The study has suggested that establishment of producer co-operatives to handle various activities relating to production and marketing of vegetables would help in reducing post-harvest losses.

Florida Agriculture and the Vegetable Industry
Provedor de dados: 31
Autores: Stevens,   Thomas J., III; Hodges,   Alan W.; Mulkey,   W. David.
Florida ranked ninth in the U.S. in agricultural receipts for the year 2000, and ranked first or second in receipts for 12 of the nation's top 25 agricultural commodities. Ten of these twelve leading agricultural commodities were fresh fruits or vegetables, and combined, they represented over 45 percent of the state's agricultural receipts in 2000. Despite Florida's preeminent standing as a producer of fresh fruits and vegetables, it's future leadership in this industry is less clear. In real terms, Florida's annual agricultural receipts have declined from $7.41 billion in 1992, to $6.42 billion in 2001. In 2000, receipts fell by over $521 million, the sharpest one-year drop since 1990. The overall trend in fresh vegetable receipts for the State has been...

Border Effects on Spatial Price Transmission between Fresh Tomato Markets in Ghana and Burkina-Faso: Any Case for Promoting Trans-Border Trade in West Africa?
Provedor de dados: 31
Autores: Amikuzuno,   Joseph.
Cross-border trade in food commodities within sub-regional economic blocks in Sub-Sahara Africa (SSA) is believed to be faster, cheaper, more convenient and welfare-enhancing than overseas trade between SSA countries and the USA, EU and the BRIC countries. The difficulty of commodity arbitrage across international borders SSA is however a fundamental constraint to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade in Africa. This study examines the impact of border and distance on price transmission between tomato markets in Ghana and Burkina-Faso. The analysis applies a regime-switching vector error correction model to estimate semi-weekly, wholesale prices of tomato in four tomato markets in...

Seasonal Asymmetric Price Transmission in Ghanaian Tomato Markets: Adapting Johansen’s Estimation Method
Provedor de dados: 31
Autores: Amikuzuno,   Joseph; Ihle,   Rico.
We assess market integration and price transmission of perishable agricultural produce in Sub-Saharan Africa by studying Ghanaian tomato markets which are characterized by pronounced seasonality in production and trade flows. We analyse the tomato markets of Ghana by simultaneously regarding its five most important markets, Navrongo, Techiman, Kumasi, Tamale and Accra, in a multivariate asymmetric price transmission framework. The estimation of the model is based on a unique dataset and on a modified version of the Johansen estimation procedure which is suitable for estimating such multivariate models. We estimate the price transmission parameters for four regimes which are a combination of the seasonal patterns in trade flows and asymmetries in the...

EFFECTS OF THE SUSPENSION AGREEMENT: U.S.-MEXICO FRESH TOMATOES ANTIDUMPING CASE
Provedor de dados: 31
Autores: Jung,   Jione.
This paper analyzes the effects of the suspension agreement of the U.S.-Mexico fresh tomatoes antidumping cases on U.S. consumers. A linear and dynamic version of an inverse almost ideal demand system is developed to estimate consumer behavior. The measure of consumer welfare – compensating and equivalent variations – is derived specifically for the inverse demand system. The variation of cross-price flexibilities obviously reduced since the minimum export price system came into effect, but consumer welfare does not seem to change much in the circumstance. The consumers’ budget share on domestic fresh tomatoes is likely to reduce and it suggests that the suspension agreement may not guarantee the profit of domestic producers either.

Spatial Price Transmission Analysis in Agricultural Markets: Does the Data Frequency Improve our Estimation?
Provedor de dados: 31
Autores: Amikuzuno,   Joseph.
Unavailability of high frequency, weekly or daily data compels most studies of price transmission in developing countries to use low frequency, monthly data for their analyses. Analyzing price dynamics with monthly data may however yield imprecise price adjustment parameters and lead to wrong inferences on price dynamics. This is because agricultural markets in developing countries operate daily or weekly. In this paper, we investigate the relevance of data frequency in price transmission analysis. We use a standard- and a threshold vector error model to estimate and compare price adjustment parameters for a high frequency, semi-weekly, data and a low frequency, monthly data. The results reveal that adjustment parameters estimated from the low frequency...

Autores: Ben Kaabia,   Monia; Gil Roig,   Jose Maria.
RESUMEN: El objetivo de este trabajo consiste en analizar el proceso de transmisión de precios a lo largo de la cadena comercial en el sector del tomate en España. Para ello se han considerado el precio percibido por el productor y el pagado por el consumidor. El enfoque metodológico adoptado se basa en la estimación de un Vector de Corrección del Error con umbrales. Los resultados indican que, a largo plazo, los dos precios son homogéneos. Sin embargo, en el corto plazo las reacciones de precios, tanto en velocidad como en magnitud, son asimétricas. Es más, los resultados indican que los detallistas se benefician (en el sentido de que son capaces de aumentar el margen comercial) de cualquier shock, ya sea positivo o negativo, que afecte tanto a las...

Border Effects on Spatial Price Transmission between Fresh Tomato Markets in Ghana and Burkina-Faso: Any Case for Promoting Trans-border Trade in West Africa?
Provedor de dados: 31
Autores: Amikuzuno,   Joseph.
Cross-border trade in food commodities within sub-regional economic blocks in Sub-Sahara Africa (SSA) is believed to be faster, cheaper, more convenient and welfare-enhancing than trade between SSA countries and the USA or EU. The difficulty of commodity arbitrage across borders in SSA is however a fundamental impediment to price transmission, market integration and the realisation of the welfare-enhancing role of cross-border trade. This study examines the impact of border and distance on price transmission between tomato in Ghana and Burkina-Faso. The analysis applies a linear and a regime-switching vector error correction model to estimate wholesale prices of tomato in four tomato markets in Ghana and a producer market in Burkina-Faso. The estimated...

Autores: Horna,   J. Daniela; Timpo,   Samuel E.; Al-Hassan,   Ramatu M.; Smale,   Melinda; Falck-Zepeda,   Jose Benjamin.
The objective of this study is to evaluate pesticide use as an important factor affecting potential adoption and farm level impact of genetically modified (GM) vegetable varieties in Ghana. Tomato is the most consumed vegetable and a food security crop. Cabbage is a vegetable of growing importance but limited cultivation and is produced in urban areas. Garden egg is a native African crop of wide consumption and importance for rural economies. Farm level information was collected in randomly selected sites in southern and central regions of Ghana. Partial budget analysis shows that investments in pesticides are rather low, especially for tomato and garden egg. Analysis of production using an abatement framework shows that insecticide amounts are significant...

ABSTRACT The correct characterization of germplasm banks is fundamental for breeders to succeed in breeding programs. Several studies have sought to obtain genotypes with resistance to pests. However, there is no consensus about which methodology is the most appropriate to characterize a germplasm bank of tomato with different levels of resistance to pests. The objective of this study was to compare methods of multivariate analysis for the evaluation of genetic diversity in tomato genotypes with different levels of resistance to pests. The experiments were conducted at the Vegetable Experimental Station of the Federal University of Uberlândia - Monte Carmelo campus (18º 42’ 43.19” South latitude and 47º 29’ 55.8” West longitude, 873 m altitude), in the...

Eclosion time and larval behavior of the tomato fruit borer, Neoleucinodes elegantalis (Guenée) (Lepidoptera: Crambidae)
Provedor de dados: 63
Autores: Eiras,Alvaro E.; Blackmer,Jacquelyn L.
In several regions of Brazil, Neoleucinodes elegantalis (Guenée) is one of the most serious tomato pests. The moth lays eggs on the calyx or developing fruit, and shortly after eclosion larvae penetrate into the fruit, where they remain until pupation. Once larvae have entered the fruits, insecticides and biological control agents are relatively ineffective. Because N. elegantalis is most susceptible to conventional treatments when the larvae are outside the host tissues (or fruit), it would be advantageous to know the time required for egg development and the length of time that the larvae spend on the surface of the fruit. To answer these questions detailed behavioral studies were untaken. Eggs were collected from the field and maintained in an...

Provedor de dados: 42
Autores: VILHENA,MILCA B.; FRANCO,MÔNICA R.; SCHMIDT,DAIANA; CARVALHO,GISELLE; AZEVEDO,RICARDO A.
Proteomics is an outstanding area in science whose increasing application has advanced to distinct purposes. A crucial aspect to achieve a good proteome resolution is the establishment of a methodology that results in the best quality and wide range representation of total proteins. Another important aspect is that in many studies, limited amounts of tissue and total protein in the tissue to be studied are found, making difficult the analysis. In order to test different parameters, combinations using minimum amount of tissue with 4 protocols for protein extraction from tomato (Solanum lycopersicum L.) leaves and roots were evaluated with special attention to their capacity for removing interferents and achieving suitable resolution in bidimensional gel...

Provedor de dados: 44
Autores: Guedes,Raul N. C.; Guedes,Nelsa M. P.; Picanço,Marcelo.
The effect of the systemic insecticide phorate on vegetative growth and yield of tomato (Lycopersicum esculentum Mill.) was studied in the greenhouse. Three dosages of phorate (1.5, 7.5, and 13.5 mg a.i./ 1.5 L pot) were applied along with a control (without insecticide application). The plants were harvested at 17, 32, 51, 69, and 90 days after tilling. Regression analysis did not show any significant effect of insecticide dosages in plant and root length. However, an overall negative effect of phorate was observed on leaf area, shoot and root dry weights, and fruit fresh weight. Based on multiple regression models, maximum leaf area was obtained with 6.7 mg a.i./pot and maximum shoot and root dry weights were obtained with no insecticide application and...

Supraoptimal ethylene acts antagonistically with exogenous gibberellins during Solanum lycopersicum (Solanaceae) hypocotyl growth
Provedor de dados: 51
Autores: Mignolli,Francesco; Rojas,Graciela Beatriz; Vidoz,María Laura.
In many plant species, ethylene and gibberellins interact to regulate plant growth and development. In some cases, these hormones can act in a synergistic way whereas in others they can be antagonistic. To date, the control of hypocotyl elongation by ethylene and gibberellins has been poorly explored in tomato. In this paper, we report that, application of exogenous ethylene to tomato seedlings or high endogenous ethylene production, as in the epinastic mutant, strongly prevent the effect of gibberellic acid (GA3) application. Moreover, constitutive activation of gibberellin signal in a DELLA deficient mutant is not able to counteract the inhibitory effect of ethylene on hypocotyl elongation, suggesting that ethylene acts independently from DELLA-mediated...

Autores: Udo,Idorenyin Asukwo; Osai,Ephraim Onoku; Ukeh,Donald Agioliwhu.
Glasshouse experiments were conducted to evaluate the efficacy of application frequency of a bioformulated Paecilomyces lilacinus in combination with five concentration of Lantana camara crude aqueous leaf extract against Meloidogyne incognita race I on tomato. The experiment was a 3x5 factorial laid out in a completely randomized design (CRD) with four replications. Each seedling was inoculated with 5000 eggs of M. incognita. Application of the bionematicide and L. camara leaf extract alone significantly (P≤ 0.05) inhibited root galling and egg production compared with their respective control. However, the severity of root galling and egg mass production was more significantly (P&lt; 0.05) suppressed with the application of P. lilacinus than L. camara...

ABSTRACT  Studies on seasonal dynamics of white fly (Bemesia tabaci) on tomato (Solanum esculentum var. Pusa Ruby) revealed that it appeared first during the 13th and reached maximum during 21st standard meteorological week. A positive correlation between adult population and abiotic factors viz. temperature (maximum and minimum) and sunshine hours was observed, whereas humidity (maximum and minimum) and rainfall showed a negative correlation with it. Taken together, the key weather parameters studied, caused 89.00 per cent variation in whitefly population (R2 value). Combination of carbofuran (soil application) + imidacloprid (seed treatment ) + imidacloprid (foliar application) proved significantly superior and caused maximum reduction in whitefly...

Autores: Heidari,Parviz.
Abstract Cold stress is one of the limiting factors of plant production that plants use different mechanisms for cold tolerance. CBF genes play critical role to regulate the cold responsive genes. To better understand of CBF gene functions, the tomato-CBFs and Arabidopsis-CBFs were evaluated using bioinformatics tools, and finally the expression patterns of SlCBF1 gene were analyzed under 10 and 4˚C in two contrasting tomato species (Solanum lycopersicum and S. habrochaites). The different cis regulatory elements were observed in promoter region of SlCBF1 and AtCBF1 genes, and ICE1, COR and HOS1 proteins exhibited high interaction with CBFs. The results of Real time PCR of SlCBF1 exhibited that under 10 and 4 ˚C, SlCBF1 was down regulated in cold sensitive...

Isolation, identification, and biocontrol of antagonistic bacterium against Botrytis cinerea after tomato harvest
Provedor de dados: 58
Autores: Shi,Jun-Feng; Sun,Chang-Qing.
ABSTRACT Tomato is one of the most important vegetables in the world. Decay after harvest is a major issue in the development of tomato industry. Currently, the most effective method for controlling decay after harvest is storage of tomato at low temperature combined with usage of chemical bactericide; however, long-term usage of chemical bactericide not only causes pathogen resistance but also is harmful for human health and environment. Biocontrol method for the management of disease after tomato harvest has great practical significance. In this study, antagonistic bacterium B-6-1 strain was isolated from the surface of tomato and identified as Enterobacter cowanii based on morphological characteristics and physiological and biochemical features combined...

Cloning and sequence analysis of tomato cpDNA fragments: towards developing homologous chloroplast transformation vectors
Provedor de dados: 61
Autores: Berger,Irving Joseph; Carraro,Dirce Maria; Bock,Ralph; Azevedo,Ricardo Antunes; Carrer,Helaine.
With the view of developing chloroplast transformation vectors based on homologous targeting regions for tomato (Lycopersicon esculentum L.), plastid DNA fragments of tomato cv. IAC-Santa Clara were cloned and analyzed. Isolation and cloning of PstI/SalI chloroplast fragments into the pBlueScript vectors yielded the plasmids pIJB1 and pIJB2 with cpDNA fragments of 8.6 kb and 6.4 kb, respectively. DNA sequencing and computer analyses revealed that the tomato sequences cloned display from 93 to 100 % of identity to the respective fragments in tobacco, which is more pronounced in coding regions. The intergenic spacers are somewhat less conserved suggesting that evolutionary divergences occurred mainly in these putative non-coding regions. The most remarkable...

Provedor de dados: 118
Autores: Sepúlveda-Chavera,Germán; Salvatierra-Martínez,Ricardo; Andía-Guardia,Rodrigo.
The powdery mildew complex (Leveillula taurica and Erysiphe sp.) is one of the major factors limiting tomato (Solanum lycopersicum) production in the Azapa Valley, Chile. This problem is especially severe in the case of protected crops because the options for the treatment of these crops with chemical fungicides are limited. This study evaluated the effects of 0.5 and 1.0 kg100 L-1 Ospo-V55® and 10% raw cow's milk on tomato leaflets infected by powdery mildew complex. Ospo-V55®, with active ingredients consisting of 10% p/p of algae extract (IB-101) and 0.8% of microorganism concentrate, was evaluated in this study. Ospo-V55® contains flavonoids, alkaloids and phenols, oligo- and polysaccharides, 8.6% protein, 0.5% magnesium and trace amounts of...

Abstract During the samplings described here, Aphidius avenae (=picipes) (Haliday, 1834) was collected. This species has been reported in Chile but has never been studied in terms of its relative abundance and prevalence in central and southern Chile by using classical or molecular methods. The composition of the parasitoid assemblages on several cereal aphid hosts was examined for three seasons in agricultural landscapes. In this note, we describe the prevalence of this parasitoid species in cereal aphids and other aphid hosts and discuss the abundance of this parasitoid compared to other aphid parasitoids and the probable origins of this important aphid parasitoid species in Chile. The results indicate that A. avenae has a low prevalence compared to...

Provedor de dados: 118
Autores: Piñón,Mayte.
Off-season vegetables become expensive so new technological systems are required to grow cultivars well adapted to climatic conditions throughout the year. Accordingly, a trial was performed to test 12 tomato F1 commercial hybrids in a Cuban sheltered installation based on the "umbrella" effect recommended for tropical conditions. The main goal of the trial was to study cultivar productivity and adaptation traits before offering recommendations to growers. The '37242' (7.4 kg plant-1) and 'Setcopa' (7.1 kg ha-1) F1 hybrids showed the highest marketable yields, commercialized at 93% and 87%, respectively. The performance of the '37242' was notable; its high fruit set (87%) during the hot and wet season showed its adaptation to the local conditions. The...

Reduction of incidence and severity of Septoria lycopersici leaf spot of tomato with bacteria and yeasts
Provedor de dados: 65
Autores: Blum,Luiz Eduardo Bassay.
Septoria leaf spot, caused by Septoria lycopersici, is an important disease of tomato (Lycopersicon esculentum) which is mainly controlled by fungicide sprays. One of the alternatives to reduce fungicide applications is the use of leaf antagonists such as yeast and bacterium. This study was conducted from 1994 through 1995 in Auburn, AL, USA. The pathogen and one antagonist were isolated from field plants. In greenhouse, six yeast and one bacterial isolates were tested, in a set of seven experiments. The experiments were conducted in a completely randomized design with four to eight treatments and six replications. The antagonists (1-3 × 10(8) colony forming units ml-1) were inoculated 48h before the inoculation of the pathogen (1-2 × 10(5) conidia ml-1),...
