Screening and Evaluation of Herbicide Combination in Flax Field of Ili
In this study,different herbicide combinations of 40%Liqing,56%MCPA·NA,17.5%Bispyribac-sodium and 8.8%Quizalofop-p-ethyl were used in diverse concentrations trial to explore the weed control in flax field.Herbicide was sprayed when the flax plant height was 10 cm and the weeds in the field were 2-4 leaf stage.The occurrence and recovery of herbicide damage on flax in different peri-ods were investigated.The weed control effect were also evaluated on the 1st,3rd,7th,10th and 15th days after herbicide application,including the top 5 dominant weeds'damage symptom,ratio of individu-al weeding control effect and ratio of fresh body weeding control effect.The results showed that the opti-mal herbicide combination was 1200 g/hm2 MCPA·NA and 750 mL/hm2 Quizalofop-p-ethyl by analy-sis of field survey sampled on the 30th and 45th days after treatment.The total control effect was 92.9%,compared with CK.This research provides a scientific basis for the efficient control of weeds in the flax producing areas of Ili.
