1989年,墨玉县10×10~4亩棉田除受地老虎和蓟马等常发性害虫为害外,也受蚜虫猖獗为害,6月中旬棉田百株蚜量高达4.5×10~4头,有蚜株率达100％。为了经济有效地防治棉田蚜虫,我们在全县开展合理施用农药、保护利用天敌的综合防治,有效地控制了蚜虫等害虫,确保棉花丰收。 In 1989, except for the common pests such as tiger and thrips, the 10 × 10 ~ 4 mu of cotton fields in Moyu County were also affected by the rampant aphids. In mid-June, the number of aphids in the cotton fields reached as high as 4.5 × 10 ~ 4, Aphid strain rate of 100%. In order to economically and effectively control aphids in cotton fields, we carried out rational pesticide application throughout the county to protect and control the use of natural enemies and effectively control pests such as aphids to ensure cotton harvest.
