This downy mold produces millions of new infective spores that are released to the environment. Many soil insects, however, may have a natural tolerance to this pathogen, which is not exhibited in many foliar pests. Therefore, commercial development of this fungus for biological control has primarily been targeted against foliar feeding pests. All are foliar formulations of the spores of the fungus, and as the spores are microscopic, can be applied with standard spray equipment. Safety Beauveria products are reduced risk pesticides.
Environmental safety is good.
These products are generally non-toxic to beneficial insects, however, applications to areas where bees are actively foraging should be avoided. Beauveria products should not be applied to water, as they are potentially toxic to fish. Use The start and frequency of application varies with the pest and their susceptible life stages. In all cases, insect monitoring programs should be in place. For greenhouse management, it is recommended that treatment begin as soon as the insect pests are detected.
