| description | O uso de glyphosate para o controle de plantas daninhas em soja RR® apresenta características essenciais no conceito de praticabilidade. Entretanto, apesar de não permitido na legislação brasileira, tem-se aumentado a associação com outros herbicidas para manejo de espécies de difícil controle, assim como a sua mistura em tanque em combinação com inseticidas e adjuvantes. Com o objetivo de avaliar a seletividade de cultivares de soja RR® submetidos a misturas em tanque de formulações de glyphosate (Polaris®, Roundup Ready® e Roundup WG®) com chlorimuron-ethyl (Classic®), e suas associações com óleo mineral (Joint Oil®) e inseticidas novaluron (Gallaxy 100 EC®), permethrin (Piredan®) e methomyl (Lannate BR®), um experimento foi conduzido a campo na cidade de Maracaí-SP, na safra 2006/2007. O delineamento experimental utilizado foi o de blocos ao acaso, com quatro repetições, em esquema fatorial 16 x 4, sendo 16 as associações das misturas em tanque entre as formulações de glyphosate, óleo mineral e inseticidas e quatro cultivares: Monsoy 7210RR®, Monsoy 7979RR®, BRS 245RR® e CD 214RR®. Sintomas visuais de intoxicação inicial dos cultivares estudados foram caracterizados por clorose e encarquilhamento nas folhas para todas as misturas em tanque das formulações de glyphosate + chlorimuron-ethyl, associadas ou não ao óleo mineral e inseticidas novaluron, permethrin e methomyl. Todas as misturas em tanque não promoveram reduções significativas de produtividade para os cultivares Monsoy 7210RR®, Monsoy 7979RR® e BRS 245RR® e controlaram Ipomoea spp. com eficácia apenas satisfatória a partir dos 21 DAA (dias após aplicação).<br>The use of glyphosate for weed control in soybean RR® presents essential practical characteristics. However, although not allowed by the current Brazilian legislation, the association with other herbicides has been increasing for species of difficult control, as well as the use of tank mixtures combined with insecticides and adjuvants. Aiming to evaluate the selectivity of soybean RR® genotypes submitted to tank mixtures of the glyphosate formulations (Polaris®, Roundup Ready® and Roundup WG®) with chlorimuron-ethyl (Classic®), and their associations with mineral oil (Joint Oil®) and novaluron insecticides (Gallaxy 100 EC®), permethrin (Piredan®) and methomyl (Lannate BR®), an experiment was conducted under field conditions at Maracai -São Paulo, during the 2006/2007 growing year. The experiment was arranged in a randomized complete block design with four replications, in a factorial scheme 16 x 4, with 16 representing the tank mixture associations of glyphosate formulations, mineral oil and insecticide, and the four genotypes Monsoy 7210RR®, Monsoy 7979RR®, BRS245RR® and CD 214RR®. Visual symptoms of initial intoxication in the genotypes studied were characterized by chlorosis and wrinkle in the leaves for all tank mixtures of glyphosate + chlorimuron-ethyl, associated or not with mineral oil, and novaluron, permethrin and methomyl insecticides .None of the tank mixtures promoted significant yield reductions for Monsoy 7210RR®, Monsoy 7979RR® and BRS245RR® genotypes, and controlled Ipomoea spp with satisfactory effectiveness, starting from 21 DAA (days after application). |
