Abstract
By field efficacy test method, this study determined the effect of 60% Butachlor+Oxadiazon EC on weeds and investigated the close and rice safety in direct seeded rice field during 2011 in South China. The results showed that the control efficiency on grasses weeds Echinochloa crusgalli(L.) Beauv., Leptochloa chinensis(L.) Nees and cyperaceae weeds Cyperus iria L., Fimbristylis miliacea(L.) Vahl was good by 720 ~900 g a.i./hm260% Butachlor +Oxadiazon EC before rice seedling emergence in the field. The rice was safety with the recommended dose, but phytotoxicity would appear with higher concentration and latter could return.
