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喷雾指标进行了测定。室内:雾滴容量中径(Dvm)和数量中径(Dnm)分别为85.57μm和115.24μm,扩散比(DR)为0.74;室外:雾滴DvmΦ1.2为74.86μm、DnmΦ1.2为60.64μm、DvmΦ0.8为78.44μm、DnmΦ0.8为65.43μm,扩散比DRΦ1.2和DRΦ0.8分别为0.81和0.83,杀虫效果(第7天)为73.75%～88.82%;各项性能指标均符合超低容量喷雾的要求。
Bacillus thuringiensis oil suspending agent is mainly used for the ultra-low volume spray of ground instruments and aircraft, especially suitable for the prevention and treatment of forest pests. The author of the Bacillus thuringiensis oil suspension ultra-low volume spray indicators were measured. Indoor: the droplet diameter (Dvm) and number diameter (Dnm) were 85.57μm and 115.24μm, respectively, and the diffusion ratio (DR) was 0.74. In the outdoor, the droplet DvmΦ1.2 was 74.86μm and DnmΦ1.2 was 60.64μm , DvmΦ0.8 was 78.44μm, DnmΦ0.8 was 65.43μm, diffusion ratio DRΦ1.2 and DRΦ0.8 were 0.81 and 0.83 respectively, and the insecticidal effect (day 7) was 73.75% -88.82%. The performance indexes Meet the requirements of ultra-low volume spray.
