Control Effects of Different Herbicides on Weeds in Sugarcane Fields
摘要
Abstract
This study aims to determine the control effects of different herbicides on weeds in sugarcane fields in Dehong,Yunnan.Field control experiments were carried out with 2-methyl-4-chlorophenoxyacetic acid(MCPA)-ametryn-diuron 56%WP,mesotrione 15%SC,and mesotrione-ametryn-cyanazine 38%WP.The results showed that the three herbicides had good control effects on weeds in sugarcane fields at the recommended doses.The control effects of the three herbicides on the total weeds in sugarcane fields varied between 94.31%and 95.74%on day 15 after application and exceeded 97%on day 40 after application.None of the three herbicides showcased phytotoxicity,and the recommended doses were safe for sugarcane growth.Therefore,the three herbicides can be promoted and used in the control of weeds in sugarcane fields.The herbicides should be applied at the recommended doses during the 3-to 5-leaf stage of sugarcane when the weeds grow to about 10 cm.关键词
