“…Compatibility of herbicide-insecticide combinations has been evaluated in soybean [Glycine max (L.) Merr.] (Campbell and Penner 1982;Hayes et al 1979;Waldrop and Banks 1983) and in field corn (Zea mays L.) (Biediger et al 1992;Frazier et al 1993;Kapusta and Krausz 1992;Morton et al 1993), and has most often involved soil-applied insecticides. Huckaba and Coble (1990) reported a reduction in adult and larval soybean infesting thrips after POST application of the herbicide naptalam plus dinoseb.…”

RESUMO-O sucesso de uma aplicação de herbicida está diretamente relacionado a uma boa deposição da calda no alvo, com o mínimo de perdas para o ambiente. Assim, o presente trabalho objetivou avaliar a deposição e o controle de plantas daninhas promovido pela aplicação de glyphosate em diferentes volumes de calda e com a adição do adjuvante nonil fenol etoxilado. O experimento foi conduzido em delineamento de blocos casualizados com quatro repetições, em esquema fatorial 3x2, sendo três volumes de calda (30, 60 e 150 L ha-1) e duas composições (com e sem adjuvante adicionado ao tanque). Inicialmente, foi realizada a caracterização físico-química das caldas pulverizadas. Foram avaliados, após a aplicação do glyphosate, utilizando pontas de pulverização hidráulicas de jato plano defletor: deposição de calda no alvo, perdas para o solo e controle de plantas daninhas. O adjuvante promoveu alterações de pequena magnitude nas propriedades físico-químicas da solução. Conclui-se que os menores volumes de calda proporcionaram maiores deposições nas plantas daninhas e menores perdas para o solo. O herbicida estudado proporcionou bom controle das plantas daninhas, independentemente da utilização do adjuvante e do volume de calda. Palavras-chave: deposição de calda, herbicida, propriedades físico-químicas, tecnologia de aplicação. ABSTRACT-A successful herbicide application is dependent upon a good spray deposition on the target, with a minimum loss to the environment. Thus, this study aimed to evaluate spray deposition and weed control with glyphosate using different spray volumes and with the addition of the adjuvant nonyl phenol ethoxylate. The experiment was conducted in a randomized block design, in a factorial model 3x2, with three spray volumes (30, 60, and 150 L ha-1) and two spray solution compositions (with and without adjuvant added to the tank). Initially, the physical-chemical properties of the solutions were evaluated under laboratory conditions. Spray deposition, loss to the soil, and weed control were investigated. The adjuvant promoted minor alterations in the physical-chemical properties of the solution. It was concluded that the lowest spray volumes showed the best weed deposition, and the lowest loss for the soil. The adjuvant did not alter the results. The herbicide provided a good weed control irrespective of the volume and adjuvant used. INTRODUÇÃO As plantas daninhas prejudicam o desen-volvimento e a produtividade de muitos cultivos agrícolas, principalmente pelo fato de compe-tirem com a cultura por água, luz, nutrientes e espaço físico. Os prejuízos em produtividade decorrentes dessa competição devem-se espe-cialmente ao fato de que nas áreas agrícolas as plantas daninhas geralmente ocorrem em densidades bem superiores às das espécies cultivadas (Bianchi et al., 2006).

“…Crop response to multiple pesticide applications has become a concern, especially as interactions between herbicides and organophosphate insecticides have been documented to cause foliar injury and reduce yields (2, 3,9,24). Field experiments conducted during 1989 indicated that severe com injury may occur if terbufos is applied in-furrow at planting and a sulfonylurea herbicide, nicosulfuron or primisulfuron {2- [[[[[4,6-bis(difluoromethoxy)-2-pyrimidinyl]amino]carbonyl]amino]sulfonyl]benzoic acid methyl ester}, is subse quently applied POST (11,19,22,25).…”

Field experiments were conducted in Michigan, Minnesota, and Wisconsin in 1990 to explore interactions between nicosulfuron applied POST and terbufos insecticide at 0.06 or 0.11 g ai/m of row applied in-furrow on ‘Pioneer 3751’ field corn and ‘Jubilee’ sweet corn. Nicosulfuron at 0, 70, and 140 g ai/ha plus nonionic surfactant and 28% nitrogen fertilizer was applied to both corn types. Field corn response to nicosulfuron and terbufos was similar at all locations, whereas sweet corn injury varied with location. Nicosulfuron injured field corn more when applied at the four-leaf than the three-leaf stage. Injury to both corn types increased as nicosulfuron rate increased or when applied following terbufos. Nicosulfuron at 140 g/ha without terbufos did not reduce yield of either corn type; however, corn previously treated in-furrow with terbufos reduced yield.

“…This mechanism also might be responsible for the increased control of both Echinochloa species with the mixture of bispyribac-sodium with diazinon observed in this study. Interactions of various kinds between herbicides and insecticides when applied in mixtures have been reported in the literature (Byrd and York 1988;Campbell and Penner 1982;Pankey et al 2004;Waldrop and Banks 1983). Recent studies reported that some fungicides also might reduce weed control when applied in mixture with certain herbicides (Lancaster et al 2005a,b,c,d).…”

Bispyribac–Sodium Efficacy on Early Watergrass (Echinochloa oryzoides) and Late Watergrass (Echinochloa Phyllopogon) as Affected by Coapplication of Selected Rice Herbicides and Insecticides

Experiments were conducted to evaluate the effect of application rate, growth stage, and tank mixing azimsulfuron, bentazon, MCPA, propanil, or cyhalofop on the efficacy of bispyribac–sodium against early watergrass and late watergrass from rice fields in northern Greece. Mixtures of bispyribac–sodium with the insecticides carbaryl, diazinon, and dichlorvos were also evaluated. Bispyribac–sodium (24 to 36 g ai/ha) applied alone at the three- to four-leaf growth stage provided 89 to 100% control of early watergrass and 84 to 100% control of late watergrass. When bispyribac–sodium was applied alone at the five- to six-leaf growth stage of early watergrass and late watergrass, control ranged from 78 to 100% and 71 to 100%, respectively. Mixtures of bispyribac–sodium with azimsulfuron provided better control of both species at any growth stage than bispyribac–sodium applied alone. On the contrary, mixtures of bispyribac–sodium with bentazon, MCPA, or propanil were less effective on both species at any growth stage than bispyribac–sodium applied alone. A slight efficacy reduction occurred on both species for the mixture of bispyribac–sodium with cyhalofop. Mixtures of bispyribac–sodium with the insecticides carbaryl or dichlorvos showed reduced efficacy on both species, whereas increased efficacy on both species was observed for mixtures of bispyribac–sodium with diazinon as compared with the single application of bispyribac–sodium.
