湖南文理学院专家近期研究了3种除草剂不同配比防除狗牙根草坪内泽漆的效果,并筛选出最优防除方案,为有效防除泽漆提供了科学依据。研究人员用77.7%草甘膦铵盐可溶粒剂、56%2甲4氯钠可溶性粉剂、40%苄·二氯(苄嘧磺隆+二氯喹啉酸)可溶性粉剂正交组合的16种不同配比对泽漆进行防除,在施药后3、6、12、20、30天分别观察记载泽漆外观状态,统计死亡植株数,计算药效指数、株防效,并在施药后3、6、12、20、30、45天观测记载狗牙根生长情况。
Hunan University of Arts and Science experts recently studied the effect of different proportions of three herbicides on the prevention and treatment of bermudagrass lacquer, and screened out the best program of prevention and control, providing a scientific basis for the effective control of lacquer. Researchers used 77.7% ammonium glycyrrhizinate soluble granules, 56% 2 methyl sodium chloride soluble powder, 40% benzyl dichloride (bensulfuron + quinclorac) soluble powder orthogonal combinations of 16 species Different proportions of Ze paint to control, were observed at 3,6,12,20,30 days after application of Ze paint appearance, statistics, the number of dead plants, calculate the drug efficacy index, strain control effect, and after application 3, 6, 12, 20, 30, 45 days observation records of bermudagrass growth.
