九种除草剂对大豆田一年生杂草防除效果及作物安全性评价
Evaluation of Control Effect and Crop Safety of Nine Herbicides on Annual Weeds in Soybean Fields
摘要
Abstract
In order to provide a theoretical basis for the rational selection and application of stem and leaf herbicides in the actual production of soybean fields.In this study,nine stem and leaf herbicides were selected and a randomized block trial design method was adopted to conduct field efficacy tests.The results showed that,the fresh heavy control efficacy o 30 days after application of 240 g·L-1 of clethodim EC and 108 g·L-1 of haloxyfop-p EC on Echinochloa crus-galli were above 90％.The control efficacy of 250 g·L-1 fomesafen AS,480 g·L-1 bentazon SL,84％cloransulam-methyl AS on broad-leaved weed were above 80％.The total control efficacy of 480 g·L-1 clomazone EC and self-mixing were more than 80％,the total control effect of 35％bentazon·quizalofop-p-ethyl·fomesafen EC and 37％fomesafen·bentazon·clethodim OD were above 90％.480 g·L-1 clomazone EC,self-mixing and two compound agents were harmful to soybean.Compared with blank control,the yield increase of each treatment group was 37.27％—66.31％.In conclusion,the weed control spectra of different herbicides are different,and there are also certain differences in safety for soybeans.The total weed control effect of the two compound agents is excellent.Although they cause certain phytotoxicity to soybeans,the yield difference is not obvious compared with the artificial treatment group.关键词
