【Abstract】 The research was conducted to determine the effect of chemical weed control in rice field in Hutuo River area.Compared with Bensulfuron methyl which is the main herbicide used locally,PCP+Na+MCPA+Nap+Prometry with wide weed controlling spectrum,can kill quickly Potamogeton distinctus in rice fields.The experiment also showed that early application of Pcp+Na+MCPA+Nap+Prometryne could control the growth of Echinochloa crusgalli and Cyperaceae weeds.更多还原
