辣椒素粉剂防治书虱的效果

分别对室内袋装稻谷、平房仓小区、浅圆仓和房式仓实仓进行辣椒素粉剂防治储粮稻谷书虱试验,结果表明,2%辣椒素粉剂对袋装稻谷书虱的有效作用时间可达3个月,是空白对照组的3倍;平房仓小区试验中,2%辣椒素粉剂优于3%书虱灵粉剂、10%书虱灵乳剂、10%浏阳霉素,2%辣椒素粉剂处理的书虱密度最大仅为其他3种处理的2/5;在浅圆仓表面粮层施用2%辣椒素粉剂40kg,可以控制书虱的发生和为害,在房式包装粮仓施用2%辣椒素粉剂20kg,可使书虱密度降低50%.

Effect of capsaicin powder on the prevention of booklice

The experiment was done on packaged storage rice, horizontal warehouse plot, shallow along bin and house warehouse by using 2% capsaicin powder to control booklice. The results showed that he effect time of 2% capsaicin powder to control booklice was 3 months, which was 3 times of CK processing in rice packaged indoor experiment. In horizontal warehouse plot experiment, the control effect of 2% capsaicin powder to booklice was better than 3% effective drug to booklice powder, 10% effective drug to booklice emulsifier, 10% Liuyang mold antibiotic. The density of booklice of 2% capsaicin powder processing was only 2/5 times of other three processings. Only 40 kg of 2% capsaicin powder used on the surface layer grain in shallow along bin could control occurrence and harm of booklice and 20 kg was enough to reduce the booklice density of 50% in packaged rice house warehouse.
