Management of curly top in sugarbeet with seed and foliar insecticides
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Wenninger, E.J.; Eujayl, Imad A.
Curly top in sugarbeet can result in severe yield losses and is caused by Beet severe curly top virus (BSCTV) and other closely related Curtovirus spp. which are vectored by the beet leafhopper.  Neonicotinoid seed treatments (Cruiser, NipsIt, and Poncho) have been shown to be an effective supplement to host resistance, but measures to extend control beyond the duration of seed treatment efficacy needs to be investigated.  In 2012, a field study was arranged in a randomized complete block design with 8 replications and planted with the cultivar B-42.  The 16 treatments included untreated and Poncho Beta treated seed with and without 6 foliar insecticides (applied 7 days before and 6 days after release of viruliferous beet leafhopper) and just Poncho and...

Autores: Strausbaugh, C.A.; Eujayl, Imad A.; Foote, P.
Insect feeding and vectoring of viruses cause serious problems in sugarbeet production worldwide.  In order to ameliorate insect and disease problems on sugarbeet, two seed treatments, Poncho Beta (60 g a.i. clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seed) and Cruiser Tef (60 g a.i. thiamethoxam + 8 g a.i. tefluthrin/100,000 seed) were investigated (the neonicotinoid was tested alone in some trials).  The two seed treatments and an untreated check were tested in a series of seven field trials from 2006 to 2008 along with various commercial sugarbeet cultivars in a randomized complete block design with eight replications per trial.  Natural insect incidence and curly top symptoms were evaluated.  Both Poncho and Cruiser provided significant reduction...

Autores: Strausbaugh, C.A.; Rearick, E.; Eujayl, Imad A.; Foote, P.
Sucrose loss in sugarbeet storage is a concern for all roots, but particularly those stored under ambient conditions.  In order to control or suppress insect issues in sugarbeet production and consequently improve root storability, two neonicotinoid seed treatments, Poncho Beta (60 g a.i. [active ingredient] clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seeds) and Cruiser Tef (60 g a.i. thiamethoxam + 8 g a.i. tefluthrin/100,000 seeds), were used to produce roots from four commercial sugarbeet cultivars grown in Declo, ID.  At harvest, eight-beet samples from each cultivar-treatment combination were collected and placed inside an outdoor pile.  Samples were removed on approximately 30-day intervals beginning on December 6 and 8 in 2008 and 2009,...

Autores: Strausbaugh, C.A.; Wenninger, E.J.; Eujayl, Imad A.
Curly top caused by Curtovirus species is a widespread disease problem vectored by the beet leafhopper in semiarid sugar beet production areas.  The insecticide seed treatment Poncho Beta has proven to be effective in controlling curly top in sugar beet, but was only evaluated under light to moderate disease pressure.  Thus, the insecticide seed treatments Poncho Beta, NipsIt INSIDE, and Cruiser Force were evaluated under severe curly top pressure (6 viruliferous beet leafhoppers per plant) in field studies during the 2010 and 2011 growing seasons on two commercial sugar beet cultivars.  In addition, the foliar insecticides Movento, Provado, and Scorpion were also evaluated.  The seed treatments and Scorpion reduced curly top symptoms by 33 to 41% (P...

Length of efficacy for control of curly top in sugar beet with seed foliar insecticides
Provedor de dados: 18
Autores: Strausbaugh, C.A.; Wenninger, E.J.; Eujayl, Imad A.
Curly top in sugar beet caused by Beet curly top virus (BCTV) is an important yield limiting disease that can be reduced via neonicotinoid and pyrethroid insecticides.  However the length of efficacy of these insecticides is poorly understood, so a series of field experiments was conducted with the seed treatment Poncho Beta (60 g a.i. clothianidin + 8 g a.i. beta-cyfluthrin/100,000 seed) and foliar treatment Asana (55.48 g a.i. esfenvalerate/ha).  A series of four experiments were conducted in 2014 and repeated in 2015 with four treatments (untreated check, Poncho Beta, Asana, and Poncho Beta + Asana) which were arranged in a randomized complete block design with 8 replications.  To evaluate efficacy, viruliferous (contain BCTV strains) beet leafhoppers...

Impact of cultivation systems on Dichelops melacanthus (Dallas) (Heteroptera: Pentatomidae) population and damage and its chemical control on wheat
Provedor de dados: 82
Autores: Chocorosqui,Viviane R.; Panizzi,Antônio R.
Results of field evaluations indicated that the neotropical pentatomid Dichelops melacanthus (Dallas) is associated with wheat, Triticum aestivum L. In the no-tillage cultivation system, adults and nymphs were mostly found on the soil, near the plant stems and underneath crop residues of the preceding summer crop, usually soybean, Glycine max (L.) Merrill, or corn, Zea mays L. Wheat grown under the conventional cultivation system showed minimal bug attack. D. melacanthus caused substantial damage to no-tillage wheat plants, particularly to seedlings. Bug attack reduces the number of seed heads of up to 34%. Seed yield was reduced in 31% due to the bugs' feeding, compared to plants free of damage. All developmental phases of the wheat plant were susceptible...

Provedor de dados: 82
Autores: Raga,Adalton; Sato,Mário E.
Laboratory studies were conducted to determine the mortalities caused by spinosad in Ceratitis capitata (Wied.) and Anastrepha fraterculus (Wied.). Spinosad formulated bait, diluted in water, was compared with baits of malathion, trichlorfon, fenthion and deltamethrin. The lethal time increased for C. capitata (medfly) adults fed in lower concentrations of spinosad. The LT50 values for C. capitata were estimated in 106, 126 and 154 min for 80, 8 and 4 ppm, respectively. No differences at LT50 were observed for different ages, 2-3d, 3-5d and 5-7d old C. capitata exposed to 80 ppm. Both fruit fly species presented similar pattern of survival when treated with spinosad at 80 ppm. In general, fenthion and trichlorfon showed LT50 values lower than spinosad for...

Crop Choice, Non-Target Pest Levels, Yield Loss and Their Effect on Insecticide Use in South Dakota
Provedor de dados: 31
Autores: McDonald,   Tia Michelle; Keating,   Ariel Ruth; Fausti,   Scott W.; Li,   Jing; Lundgren,   Jonathan G.
Agriculturally, South Dakota is a unique state possessing the highest rate of adoption for genetically modified crop varieties.  In 2009 ninety-six percent of corn acres planted in South Dakota were genetically modified compared with eighty-five percent nationally (Economic Research Service).  Additionally, South Dakota has seen a dramatic increase in the number of acres treated with insecticide over the past 20 years.  These two situations taken together seem to be counterintuitive.  Some genetically modified varieties, such as Bt corn, are equipped with genetic defenses so that they can protect the plant from target pests.  Intuitively, one would expect to see a decrease in insecticide use as adoption of genetically modified varieties increase.  Recent...

ABSTRACT American bollworm (ABW), Helicoverpa armigera (Hubner), is considered as a major pest of cotton, Gossypium hirsutum, all over the globe. Due to its destructive feeding nature and continuous consumption of the same chemicals, it devolved resistant against many insecticides. Therefore, a combined application of bio- and synthetic-pesticide need to evaluate against this pest. The entomopathogenic viruses like nuclear polyhedrosis virus (NPV), a member of baculoviruses, can be the potential candidates for better control against ABW. The present study was conducted to assess the comparative efficacy of NPV and Spinosad 240SC (with the concentration of 250 mL · ha-1) against ABW in the controlled environment. The ABW was treated with different...

Autores: Grohs,Mara; Marchesan,Enio; Tomazetti,Marcos Belinazzo; Roso,Rodrigo; Formentini,Tiago Constante.
ABSTRACT  The rapid and uniform establishment of rice crops is important for improving production. However, this condition is influenced by several factors, including the soil temperature when planting, which may delay seed germination and compromise the final stand. The aim of this study was to evaluate the behaviour of substances which have the effect of growth regulator when applied to the seeds of different rice cultivars under low-temperature conditions. The experiment was carried out in a completely randomised design with four replications in a bi-factorial scheme, where factor A was represented by the different products (gibberellic acid - AG3, tiamethoxam - TMX, Haf Plus® - HAF, and a control with water - TEST), and factor B by the irrigated rice...

Impact of Bt sweet corn on lepidopteran pests in Midwestern Brazil
Provedor de dados: 63
Autores: Schneider,Altair Marcos; Gontijo,Lessando Moreira; Costa,Lilian Lucia.
ABSTRACT: While the cultivation of conventional Bt corn has been widely adopted in Brazil, the production of Bt sweet corn is still incipient. The main lepidopteran pests found attacking conventional and sweet corn in Brazil are Spodoptera frugiperda (J.E. Smith) and Helicoverpa zea (Boddie). Additionally, a new harmful Lepidoptera species has recently appeared in Brazil, Helicoverpa armigera (Hübner). Since Bt sweet corn in Brazil is as yet cultivated on a limited scale there is no scientific information available about the performance of Bt sweet corn against lepidopterans out in the field. Thus, we conducted two field experiments to evaluate the efficacy of Bt sweet corn (event MON89034), alone and in conjunction with insecticides, against major...

ABSTRACT Cardanol is a constituent of Cashew Nut Shell Liquid that presents larvicidal activity against Aedes aegypti. The isolation of cardanol is somewhat troublesome, however, in this work we describe an efficient and inexpensive method to obtain it as a pure material. The compound was used as starting material to make chemical transformation leading to saturated cardanol, epoxides and, halohydrins. These derivatives were tested for toxicity against Aedes aegypti larvae. The results showed that iodohydrins are very promising compounds for making commercial products to combat the vector mosquito larvae presenting a LC50 of 0.0023 ppm after 72 h of exposure.

Toxicity of fenthion to Anastrepha fraterculus (Wied.) (Diptera:Tephritidae): dose response analysis
Provedor de dados: 44
Autores: Da Cruz,Ivana B. M.; Humeres,Eduardo; Oliveira,Alice K.
Three toxicological bioassays were performed in two F1 south Brazilian field populations of Anastrepha fraterculus (Wied.). Lethal doses of fenthion (50% and 90%) were estimated in two bioassays, with oral administration, and with residual contact bioassay. Results of topical bioassays using fenthion diluted in alcohol, acetone or water were inconsistent. Samples treated with acetone or alcohol diluents presented high mortality (&gt;10%), while the samples treated with water diluent showed a non linear response between dose and mortality. The residual contact bioassay was significatively more toxic when compared to a feeding bioassay, occurring equal slopes in males and females in the populations analysed. Additional test showed that insects did not...

Age and time exposure-related toxicity of fenthion to male and female Anastrepha fraterculus (Wied.) (Diptera: Tephritidae)
Provedor de dados: 44
Autores: Humeres,Eduardo; Da Cruz,Ivana B.M.; Oliveira,Alice K. de.
Effect of age, sex and time exposure of Anastrepha fraterculus (Wied.) to toxicity of fenthion was evaluated. The age of the flies was important to the appearance of the first intoxication symptoms; males and females of reproductive ages (30 and 60 days-old, respectively) were less susceptible to insecticide than flies in the remainder ages (four and 120 days-old). The effect of body weight on insect intoxication was not detected. LT 50 biossay with fenthion (varying from 3-7 minutes) showed a lower susceptibility of males than females at all ages. Adults of both sexes and 30 days-old submitted to continuous and discontinuous exposure to fenthion did not show toxic cumulative effect of the insecticide. The statistical analysis suggests a possible general...
