Objective To explore the dosage of beta cypermethrin against Aedes albopictus by ultra low volume ( ULV ) spraying in Guangzhou City. 目的探索在广州市城区采用高效氯氰菊酯进行现场超低容量(ULV)喷雾,杀灭室外白纹伊蚊成蚊的合适喷药量。
Ultra low volume sprayers have been developed since 1978. There has been a lack of study on spraying functions of sprayer previously. Pesticide is utilized inefficiently, Which has caused environment pollution and increased cost. 我区从上个世纪70年末开始研制超低量喷雾机,由于以前忽视了对喷雾机的喷雾性能的研究,因此,农药的有效利用率很低,引起了环境污染和成本增加。
The control efficiency of ultra low volume spraying technique of oil solution of B.bassiana and deltamethrin against Dendrolimus punctatus was studied. 对不同浓度白僵菌油剂与溴氰菊酯混合超低量喷雾防治马毛松毛虫的效果进行了研究。
The oil-based suspension of Bacillus thuringiensis is mainly applied to the ultra low volume spraying of mist sprayer and aeroplane, especially apt to control forest pest insect. 苏云金杆菌油悬浮剂主要用于地面器械和飞机的超低容量(ULV)喷雾,特别适宜于森林害虫的防治。笔者对苏云金杆菌油悬浮剂超低容量(ULV)喷雾指标进行了测定。
