Abstract
Field experiment was conducted to detect the weed control effect and rice safety evaluation of different herbicides in wet direct-seeding rice field.The results showed that under each reagent supply,whether it was applied by seeding and spray synchronous or via drone spraying,4％pyraclostrobin suspension concentrate+30％pretilachlor oil dispersion(containing safener),4％pyraclostrobin suspension concentrate+90％thiobencarb emulsifiable concentrate+10％bensulfuron-methyl wettable powder,and 25％benzobicyclon suspension concentrate+30％bensulfuron-methyl·pretilachlor oil dispersion(containing safener)had excellent control effect on weeds,and the control effect of weeds was 91.2％-95.1％14 days after treatment.There was no adverse effect on the growth indexes of rice,such as plant height,tiller number and plant fresh weight.In summary,the compound of 4％pyraclostrobin suspension concentrate or 25％benzobicyclon suspension concentrate has the potential to become a product that can be alternated with bensulfuron-methyl·pretilachlor in wet direct-seeding rice fields.关键词
