1996年—1997年我们在辽宁省盖州市熊岳镇望儿山村进行了一次心叶施药,控制高粱生育期发生的二代粘虫、玉米螟、玉米蚜虫和高粱蚜虫四种害虫的防治研究,获得了可喜效果。其中667m~2施3％呋喃丹颗粒剂1公斤的,防治二代粘虫效果达98.64％-100％;对后来相继发生的玉米螟兼治效果为83%—97%;对玉米蚜虫的兼治效果为96.95％;对高梁蚜虫,在百株蚜量达50-60万头时,兼治效果为98.02％-99.29%。在整个生育期不用再行打药防治。 1996-1997 We conducted a leaf application in the Wangershan Village, Xiong Yue Town, Gaizhou City, Liaoning Province to control and control the four pests of the second generation armyworm, corn borer, corn aphid and sorghum aphid occurring in the growth period of sorghum Research, received gratifying results. Among them, 1 kg of 3% carbofuran granules at 667m ~ 2 was applied to control the second-generation armyworm, and the effect was 98.64% -100% against the second generation armyworm and 83% -97% against the corn borer which occurred one after the other. Was 96.95%. For sorghum aphid, when the amount of aphids reached 500,000 to 600,000 heads, the concurrent treatment effect was 98.02% -99.29%. In the whole growth period do not have to fight drug control.
