Abstract:The control effects of pyriminobac-methyl on barnyard grass Eehinochloa crusgalli (L.) Beauv.] and the safety in rice were researched in greenhouse. The results showed that pyriminobac-methyl 10% WP could control different growth stage ofbamyardgrass at 45 g/hm2 without any injures to be observed in rice below 120 g/hm2.
Keywords:pyriminobac-methyl  bamyard grass  rice  control effects
