چکیده
O controle do capim-amargoso (Digitaria insularis (L.) Fedde) é um desafio na cultura da soja, e os herbicidas pré-emergentes surgem como opção de manejo. objetivo desse trabalho foi avaliar o através posicionados em diferentes regimes hídricos quantidades palha. experimento realizado casa vegetação com delineamento experimental inteiramente casualizado esquema fatorial 6 x 3, no primeiro fator alocou-se segundo (diclosulam (29,4 g.i.a ha-1); flumioxazin + imazethapyr (50 106 ha-1) diuron sulfentrazone (420 210 ha-1)) esses fatores foram isolados para as palha milho Brachiaria ruziziensis (0 3 t ha-1). Na aplicação diretamente solo sobre palha, diclosulam apresentou menores porcentagens todos primeira chuva 5 mm segunda 20mm. Já não apresentaram diferenças significativas nos controlando adequadamente capim-amargoso. A eficácia sofreu influência dos intervalos seca após a aplicação, eficiente tratamentos.
