Control Efficacy of 33％Quizalofop-P-Tefuryl·Bentazone EC on Annual Weeds in Soybean Field
摘要
Abstract
In order to confirm the control effect of stems-leaves spraying herbicide 33％quizalofop-P-tefuryl·bentazone EC on annual weeds in soybean field under different treatments,the field trials were conducted using randomized block method.The results denoted that 33％quizalofop-P-tefuryl·bentazone EC had a better control effect on the annual weeds Echinochloa crus-galli L.,Chenopodium album L.,Persicaria bungeana(Turcz.)Nakai ex T.Mori,Solanum nigrum L.and Abutilon theophrasti Medikus in soybean field when the dose was more than 1 500 mL·ha-1.The plant control efficacy and fresh weight control efficacy on the total weed were respectively 85.5％-97.7％and 89.3％-99.2％after application 30 days,and there were no phytotoxicity to soybean under each treatment.The results of yield measurement indicated that the yield increase of 33％quizalofop-P-tefuryl·bentazone EC in each treatment was significantly increased compared with the blank control,and the incremental production rates was 187.5％-216.9％.And it showed that 33％quizalofop-P-tefuryl·bentazone EC was safe for soybean and had better control effect on weeds.The appropriate dose is 1 500-1 800 mL·ha-1(the effective component of 495.0-594.0 g·ha-1).关键词
