Abstract
【Objective】 The study was to explore the control effects of three kinds of herbicides in different matching on Euphorbia helioscopia,and to screen the best plan for control.【Method】 The three kinds of herbicides of 16 assemblages were used to control E.helioscopia that used orthogonal design on 77.7% Glycine,56% MCPA-Na and 40% bensulfuron-methyl+quinclorac in different matching.The efficacy indexes and control effects are observed in three,six,twelve,twenty and thirty days after pesticide application.And the influence on the growth of Cynodon dactylon are observed in three,six,twelve,twenty,thirty and forty-five days after pesticide application.【Result】 The 16 assemblages' efficacy was greatly different(P0.05).The efficacy of the three kinds of herbicides mixing is the best,and the efficacy of the two kinds of herbicides mixing is better than the single herbicide used on E.helioscopia.The efficacy index and the control effect are increasing with the respective concentration increase.The best efficacy of E.helioscopia control was the assemblage of 40% bensulfuron-methyl+quinclorac 85 mg/m2 and 56% MCPA-Na 300 mg/m2 and 77.7% Glycine 420 mg/m2.The efficacy indexes are 96.0% and 97.6%,and the control effects are 88.9% in three and six days after pesticide application,the efficacy index and the control effect is all 100% in twenty days after pesticide application,and the treated plants did not regenerate in thirty days after pesticide application.The influence on the growth of C.dactylon is visible tiny injuring or not with single herbicide used.The influence on the growth of C.dactylon is visible in three to twenty days after application,and reduced in thirty days after application,and recovered at forty-five days after application with two or three kinds of herbicides mixing used.【Conclusion】 The assemblage of 40% bensulfuron-methyl + quinclorac 85 mg/m2 and 56% MCPA-Na 300 mg/m2 and 77.7% Glycine 420 mg/m2 can control E.helioscopia in C.dactylon turf.
