地膜覆盖对单清缓控颗粒剂防治甘蔗害虫效果的影响

摘要

This paper analyzes the effect of film mulching and without film mulching on Danqing slow-release pesticide to controlling sugarcane pests. The results showed that, after 50 days and 80 days, under the condition of film mulching, the average control effect of Danqing pesticide on sugarcane borer in three test sites reached 91.13% and 91.71% respectively, which were significantly higher (12.87% and 16.15%) than that of the treatments with no film mulching. Under the condition of film mulching, the average control effect of Danqing pesticide on sugarcane woolly aphid, thrip and chafer in three test sites were 96.59%, 98.92% and 96.11% respectively, which were significantly higher (10.48%, 11.06% and 17.56%) than that of the treatments with no film mulching. It is indicated that Danqing slow-release pesticide with film mulching was worth extension in controlling sugarcane borers.%研究了地膜覆盖及无地膜覆盖对单清(5%杀单?毒死蜱)缓控颗粒剂田间防治甘蔗害虫效果的影响.3个试验点结果显示,药后50天和80天,地膜覆盖条件下单清缓控颗粒剂对甘蔗螟虫防效分别平均高达91.13%和91.71%,较无地膜覆盖防效分别平均高出12.87%和16.15%;对甘蔗绵蚜、蓟马及金龟子的平均防效分别高达96.59%、98.92%和96.11%,较无地膜覆盖处理防效分别平均高出10.48%、11.06%和17.56%.地膜覆盖对单清缓控颗粒剂防治甘蔗害虫具有增效作用,建议在蔗区推广农药加地膜覆盖的栽培模式防治甘蔗害虫.
