| ABSTRACT In the biennium 2013-14, the world produced 1,134.27 million tons of vegetables annually. The production of garlic, onion, potato, tomato and watermelon accounted for 66.5% of the total. Brazil, in 2012, considering 40 vegetables, produced around 23 million tons, in 900.0 thousand hectares. Potatoes, tomatoes (table and processing), onions, watermelons, carrots, sweet potatoes, lettuce and cabbage, the main vegetables in Brazil, accounted for 64.0% of the total. This work presents the evolution of production, commercialization, and availability of garlic, onions, potatoes, tomatoes and watermelons in Brazil and in the world. In Brazil, the work focused on two distinct periods: 1970-1990 {when the Support Program for Production and... |

| 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... |

| O presente documento foi elaborado por ocasiao do I ENCONTRO SOBRE MENAJO DE PRAGAS DO TOMATEIRO, promovido pelo CPATSA-EMBRAPA, em Petrolina, PE, no periodo de 25 a 28 de setembro de 1989. Esse evento teve como objetivo, reunir tecnicos ligados a pesquisa, ensino, extensao e a empresas particulares, para tratas dos problemas entomologicos relacionados a cultura do tomate a nivel nacional, visando tracar diretrizes apra um programa sobre menajo integrado das pragas do tomateiro, notadamente apra a regiao do submedio Sao Francisco. Apresenta as medidas a serem adotadas, a curto, medio e longo prazos, para o problema da traca do tomateiro Scrobipalpula absoluta, a mais importante praga da cultura do tomate nessa regiao. |

| Se caracterizaron los sistemas de producción de jitomate en el Valle del Mezquital, Hidalgo; identificando a cuatro siendo: a) cielo abierto, y en invernadero con tres variantes b) producido en suelo (camas), c) en tezontle (bolsa) y d) mezcla de sustratos (tezontle-composta en bolsa), este último sistema se propuso y desarrolló experimentalmente en esta investigación. Para el análisis de cada método de producción se utilizó el muestreo no probabilístico “bola de nieve” (Cornelius, 1981) para identificar a los productores a quienes se les aplicaron entrevistas. El cuestionario incluyó una sección de características productivas, tecnológicas, de comercialización y económicas. Se encontró que los cuatro sistemas presentaron notables diferencias en todos... |

| ABSTRACT: Contamination by herbicides with a prolonged effect on the soil can cause anatomical changes in sensitive plants. Thus, this study aimed at verifying the anatomical changes of tomato stem and leaves caused by different concentrations of picloram in two classes of soil from the Amazon region. The study was developed at UNEMAT, Alta Floresta - Mato Grosso state, in a CRD, in a 2 x 5 factorial arrangement, with four replications. A clayey Rhodic Hapludox (LVAw) and a sandy clay loam Typic Ustipsamments (RQo) were contaminated with 0, 1, 2, 3, and 4 L ha-1 of Tordon®, leaving the soil exposed to weathering. One-hundred and twenty days after the application of the herbicide, 10 tomato seeds were sown in samples of both soils. Thirty days after sowing,... |

| 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... |

| A traça do tomateiro, Scrobipalpula absoluta (Meyrick) (Lepidoptera, Gelechiidae), foi constatada no final de 1981 em áreas irrigadas do Trópico Semi-Árido brasileiro, no vale do Salitre, em Juazeiro, BA. Rapidamente, em poucos meses, disseminou-se nas regiões circunvizinhas de Juazeiro, BA, Petrolina e Santa Maria da Boa Vista, PE. |

| 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... |

| 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.... |

| 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... |

| 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... |

| '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... |
