Abstract
The weed control effects of 17.5% benazolin quizalofop-p-ethyl and subsequent dynamics in rape fields,as well as the influence of 17.5% benazolin quizalofop-p-ethyl on the sunlight and crop yield were studied to evaluate the application prospect of benazolin quizalofop-p-ethyl.The results showed that benazolin quizalofop-p-ethyl provided good control effects on weeds in rape fields,the overall effects ranged from 98.82% to 99.94% twenty days after treatment(DAT),decreased and maintained above 92% for 120 DAT with gradual decrease.The efficacy was higher on Alopecurus aequalis,Beckmannia syzigachne than Malachium aquaticum.Benazolin quizalofop-p-ethyl application significantly improved the light conditions in rapeseed field and the light penetration rate increased with the dosage of herbicide.The application of benazolin quizalofop-p-ethyl had no effect on the plant height and 1 000-seed weight,whereas the height of first branch,numbers of branches and siliquas were markedly influenced,resulting in a significant yield increase of rapeseed.
