Abstract
Três experimentos de campo foram conduzidos em Latossolos Vermelho-Escuro e Vermelho-Amarelo, nos anos 1981/82 e 1982/83 com o objetivo de determinar o efeito de herbicidas para o controle de plantas daninhas angustifoliadas e fitotoxidade sobre a cultura de soja, cultivares UFV-1 e Cristalina. O grupo das acetanilidas e pendimethalin controlaram a trapoeraba. Para as três espécies latifoliadas, o acetochlor, trifluralin e oryzalin foram eficientes. Além disso, o metolachlor controlou a poaia e o pendimethalin controlou a poaia e o apaga-fogo. Para o controle do capim-marmelada, todos os produtos foram eficientes, exceto quizalofop-etil e mefluidide, enquanto que para o capim-colchão apenas o mefluidide não foi eficiente. Finalmente, o timbete não foi eficientemente controlado por alachlor, metolachlor, pentimethalin e mefluidide. Acetochlor e oryzalin afetaram negativamente o stand inicial. Além disso, o acetochlor reduziu altura da inserção da primeira vagem. O quizalofop-etil causou uma redução na produção de grãos.
Three field experiments were carried out on Dark Red Latosol and Yellow Red Latosol in 1981/82 and 1982/83 to evaluate the efficiency of herbicides upon grassy and their phytotoxicity upon “UFV-1” and Cristalina soybeans cultivars. The acetoanilide group and pendimethalin showed good epiderwort control. For the three broadleaved weed species, acetochlor, trifluralin and oryzalin were efficient. More over, metolachlor controlled Brazil pusley and A. ficoidea. For alexandergrass control all herbicides tested were efficient but quizalofop-ethyl and mefluidide, whereas crabgrass was not controlled by mefluidide only. Acetochlor and oryzalin treatments decreases initial stand. Besides, acetochlor decreased height of insertion of first pod. Quizalofop-ethil reduced grain yield of soybeans.
