扫虫光对棉铃虫的防效评价

Control Effects of Saochongguang on Helicoverpa armigera

探讨使用环境友好复合型防治害虫中试药剂扫虫光防治瓜菜害虫的发生与危害及其对作物生长发育的安全性,比较分析扫虫光对棉铃虫的防治效果及其处理对辣椒的安全性,试验结果表明:扫虫光1000倍液、1500倍稀释液不仅对棉铃虫具有良好的防治效果,而且对植株生长安全;扫虫光500倍液虽然对棉铃虫具有良好防治效果,但植株生长畸形。因此,综合考虑经济、高效和简便等因素,扫虫光1000-1500倍稀释液可广泛用于防治瓜菜棉铃虫的发生与危害。

Saochongguang developed by Environment and Plant Protection Institute, Chinese Academy of Tropical Agricultural Sciences, is a non-polluted compound pesticide. To scientifically and reasonably make full use of it to control insects of vegetable crops and make sure of its safety on crop development, its control effects on Helicoverpa armigera and safety on capsicum were studied. The results showed that 1 000-fold dilution and 1 500-fold dilution were better to control H. armigera and for the development of capsicum; 500-fold dilution was also better to control H. armigera, but the plants could not normally develop. However, 2 500-fold dilution and 3 000-fold dilution were not effective to control H. armigera. Given the economic, efficient and simple operation, 1 000 - 1 500-fold dilution of Saochongguang can be widely applied to control H. armigera of vegetable crops.
