近几年来,我们使用1605毒饵,对地老虎幼虫作了连续大面积试验,初步认为效果较好。 1605毒饵是用麦麸(或玉米渣)10斤、水2斤、1605一两配成的。先将麸子倒在盆内,然后将2斤水1两药对好的药液,慢慢倒在麸子上,随倒随搅拌,均匀后盖好,过4—6小时后即可使用。将毒饵放在簸箕内,用木棍顺风播撒。每隔2米施成1米宽的药带。虫口密度大时也可多施一些,施饵时期最好在地老虎幼虫三龄以前(4月中、下旬),这时虫小,抗药力弱,杀伤效果高。因为地老虎白天潜伏,晚上出来为害,所以
In recent years, we use 1605 poison bait, on the ground tiger larvae made a continuous large area test, initially that the effect is better. 1605 poison bait is the use of wheat bran (or corn residue) 10 pounds, 2 pounds of water, 1605 one or two match. First fall in the basin pellets, and then 2 pounds of water a good medicine for two drugs, slowly poured on the bran, with the pour stir, uniform back cover, after 4-6 hours to use . The poison bait on the dustpan, spread the wind with a stick. 1 meter wide medicinal band every 2 meters. When the density of insect population can also be applied more, the best time to feed the local tiger larvae before the third instar (mid-April, late), when the worm is small, weak resistance, high killing effect. Because tigers are lurking during the day and come out harmful at night, so
