Screening of the Formula for Wettable Powder of Beauveria bassiana with Conidia
摘要
Abstract
[Objective] The aim was to confirm the optimal formula of wettable powder of Beauveria bassiana with conidia. [ Method ] Taking the pure spore powder of B. Bassiana 2860 (conidia content is 1.20 X 10"/g)as the research object,which have the activity of killing aphid,the types and amount of carrier,wetting agent,dispersant and UV protectant were determined with the one by one screening method,and quality index was evaluated according to the rational standard. [Result] The optimal formulation were as follows:the content conidium of Bb2860,dispersing agent MorwetD425,wetting agent MF-5.UV protection agents Vc,filler diatomite were 10.0% ,1.0% ,3.0% ,0. 3% and 85. 7% .respectively. The quality detection showed that the germination rate of conidia was 94.44% and the dispersion time was 89.2 s,and the suspension rate of effective component was 95.11% ,and the moisture content was 1.50% ,the ratio transiting standard test sieve with 200 meshes was 98.50% and pH was 6. 8. [Conclusion] The indexes of the formulation meet the national formulations standard, which lay the foundation for the development of B. Bassiana biological control products.关键词
