Bacillus thuringiensis applied to stored corn using grain drying fans






Journal of the Kansas Entomological Society 59(2): 350-355

Bacillus thuringiensis applied to stored corn using grain drying fans

Bacillus thuringiensis was applied to the surface layer of stored corn as an airborne dust carried into the grain by the downward air flow of drying fans. At air flow rates of typical farm-bin grain drying systems approximately 25% of the dust penetrated 2.5 to 12.5 cm into the corn and prevented infestation by Indianmeal moths, Plodia interpunctella (Hubner). Data are presented on the distribution of spores and toxic activity among particle size fractions of the dust formulation, the effects of air flow rate on depth of dust penetration, and the depth of dust penetration in farm grain drying bins.
