The compatibility of entomopathogenic microorganisms with thiamethoxam and other insecticides was studied in vitro and under field conditions. The microorganisms tested were: Aschersonia aleyrodis, Bacillus thuringiensis, Baculovirus anticarsia (NPVAg), Beauveria bassiana, Hirsutella thompsonii, Metarhizium anisopliae, Nomuraea rileyi, Paecilomyces farinosus, Sporothrix insectorum and Verticillium lecanii. Two concentrations of each product were tested in the laboratory, based on the maximum and minimum recommended rates for application in the field. The products were added to specific culture medium for growth of the entomopathogens. Reproductive and vegetative growth were evaluated for fungi, and colony forming units (CFU) were evaluated for bacteria.... |
