Resumo: This study evaluated the effect of herbicides on the population density of H. glycines in soybean cultivars, (one resistant and three susceptible) in natural infestation conditions. Experiments were done in Campo Alegre de Goiás and Gameleira de Goiás, agricultural year 2006/07, using randomized blocks, with three repetitions. The treatments were arranged in a factorial design 4 x 4 + 1, with four cultivars (BRSGO Ipameri, BRSGO Luziânia, BRSGO Jataí BRS Silvânia RR), four forms of weed control (hand weeding, chlorimuron-ethyl + lactofen, chlorimuron-ethyl and haloxyfop-methyl), and additional treatment represented by the combination of transgenic cultivar BRS Silvânia RR and herbicide glyphosate. In agricultural year 2009/2010, another test was conducted in Gameleira de Goiás, with four repetitions, in a factorial design 2 x 4 + 2, involving two cultivars (BRSGO Chapadões and BRSGO 8360), four forms of weed control (hand weeding, lactofen, chlorimuron-ethyl; haloxifop-r), and two additional treatments represented by the combination of transgenic cultivar BRS Valiosa RR with control manual weed and chemical control via herbicide glyphosate. In the agricultural year 2006/07, in Campo Alegre de Goiás, eighty days after planting, there was less formation of viable cysts in cultivar BRS Silvânia RR associated with the application of clorimuron + lactofen, compared to manual control. In Gameleira de Goias, it was found, forty days after planting, increase in the number of viable cysts using herbicides, compared with manual control, in cultivar susceptible BRSGO Luziânia, BRSGO Ipameri, resistant to H. glycines, the number of viable cysts was lower when applied herbicides clorimuron+lactofen or haloxyfop, compared the application of clorimuron. The herbicides had no effect on the number of females in susceptible and resistant cultivars in the year 2009/10. In cultivar susceptible BRSGO 8360, the herbicide haloxifop led to a smaller number of females, in comparison with clorimuron, 45 days after sowing. The herbicide lactofen, in the cultivar BRSGO Chapadões (resistant) was associated with increase in the number of viable cysts 45 days after sowing. This herbicide affects negatively the biomass of leaves, fresh green beans and dry bean in the cultivars BRSGO Chapadões and BRSGO 8360.

Experimentos foram conduzidos em Campo Alegre de Goiás e Gameleira de Goiás, safra 2006/07, utilizando delineamento de blocos casualizados, com três repetições. Os tratamentos foram arranjados em esquema fatorial 4x4+1, sendo: quatro cultivares (BRSGO Ipameri, BRSGO Luziânia, BRSGO Jataí, BRS Silvânia RR); quatro formas de controle de plantas daninhas (arranquio manual, chlorimuron-etil+lactofen, chlorimuron-etil e haloxyfop-metil); e o tratamento adicional representado pela combinação da cultivar transgênica BRS Silvânia RR e o herbicida glifosato. Na safra 2009/10, outro ensaio foi conduzido em Gameleira de Goiás, com quatro repetições, em esquema fatorial 2x4+2, envolvendo duas cultivares (BRSGO Chapadões e BRSGO 8360) quatro formas de controle de plantas daninhas (arranquio manual, lactofen, chlorimuron-etil e haloxifop-r), e os dois tratamentos adicionais que consistiram das combinações entre a cultivar BRS Valiosa RR com o controle manual das plantas daninhas e com o controle químico via herbicida glifosato. Na safra 2006/07, em Campo Alegre de Goiás, aos oitenta dias após o plantio, observou-se menor formação de cistos viáveis na cultivar BRS Silvânia RR, associado à aplicação de clorimuron + lactofen, em comparação ao controle manual. Em Gameleira de Goiás, verificou-se, aos quarenta dias após o plantio, aumento do número de cistos viáveis com o uso de herbicidas, em comparação com o controle manual, na cultivar suscetível BRSGO Luziânia, já na cultivar BRSGO Ipameri, resistente a H. glycines, o número de cistos viáveis foi menor quando se aplicou os herbicidas clorimuron+lactofen ou haloxifop, em comparação à aplicação de clorimuron. Na safra 2009/10, os herbicidas não influenciaram o comportamento das cultivares (resistente ou suscetíveis) quanto ao número de fêmeas. Na cultivar suscetível BRSGO Luziânia, o herbicida haloxifop possibilitou a formação de menor número de fêmeas, em comparação com clorimuron, aos 45 dias após o plantio. O herbicida lactofen, em BRSGO Chapadões, resistente, esteve associado com o aumento na formação de cistos viáveis, aos 45 dias após o plantio. Este herbicida afetou negativamente a produção de biomassa de planta seca, vagem fresca e vagem seca nas cultivares BRSGO Chapadões e BRSGO 8360.Made available in DSpace on 2014-07-29T16:24:16Z (GMT).
