石河子植物保护学会组织棉田虫害综合防治取得可喜成果。今年全垦区57万亩棉田的虫害危害比例由1982年的15—30％,下降到1％以下,每亩用药量分别减少50-71.4％。 去年,石河子垦区59万亩棉花因不重视科学防治虫害,虽用药次数多,但治虫效果差,使棉田的大面积虫害平均达到15％以上,最高的149团场,全团场危害面积竟达30％以上。因此,全垦区棉花单产由1981年的99.5斤,下降到89斤。

Shihezi Plant Protection Institute organized comprehensive prevention and control of cotton pests made gratifying achievements. This year, the damage ratio of pest in 570,000 mu of cotton fields in the entire reclamation area dropped from 15-30% in 1982 to below 1%, with the dosage reduced by 50-71.4% per mu respectively. Last year, 59 hectares of cotton in Shihezi reclamation area did not attach importance to scientific prevention and control of pests.

Therefore, the entire reclamation area of ​​cotton yield from 99.5 pounds in 1981, down to 89 pounds.
