A novel method for evaluating the particle behavior of a spray-dried technical concentrate and a water-dispersible granule (WDG) formulation of B. thuringiensis subsp. israelensis in an aqueous column was established. The objective was to determine the distributional behavior (minus any extraneous environmental factors) of B. thuringiensis subsp. israelensis within a water column over time. Studies showed a fairly even distribution of particles over a 16-h period for the technical concentrate and WDG formulation. The particle behavior of the WDG formulation also showed homogeneous distribution of particles at 64 and 128 h. The results demonstrated that Brownian motion plays a significant role in the particle distributional behavior of this entomopathogen.
建立了一种评估苏云金芽孢杆菌以色列亚种喷雾干燥工业浓缩物和水分散粒剂(WDG)制剂在水柱中颗粒行为的新方法。目的是确定苏云金芽孢杆菌以色列亚种在水柱中随时间的分布行为(排除任何外部环境因素)。研究表明,工业浓缩物和WDG制剂在16小时内颗粒分布相当均匀。WDG制剂的颗粒行为在64小时和128小时也显示出颗粒均匀分布。结果表明,布朗运动在这种昆虫病原体的颗粒分布行为中起重要作用。
