近几年来我区早稻、晚稻生长中后期,常受到稻飞虱不同程度的为害,轻则谷粒不饱满,重则减产4～5成,甚至颗粒无收。此虫已成为当前水稻增产的绊脚石。为筛选对防治稻飞虱高效低毒药剂,我们于一九八○年在晋江陈埭公社苏厝湖中大队进行几种新农药和贫下中农与虫害斗争中创造的土办法,进行大田防治对比和室内测定校正。经一年来的实践,现将初步结果整理于下:
In recent years, our region’s early rice, late rice growth in the late, often affected by planthoppers to varying degrees of damage, ranging from grain is not full, while the weight reduction of 4 to 5 percent, or even crop failure. This worm has become a stumbling block to current rice production. In order to screen for the effective and low-toxic agents against planthoppers, we conducted a comparison of the prevention and control measures in the field with the new soil-based method created in the struggle of several new pesticides and the poor peasants and pests of lower middle peasants in the village of Su-chu Lake, Chencai commune, Jinjiang in 1980 And indoor calibration correction. After a year of practice, the preliminary results are now organized as follows:
