Summary
Beauveria bassiana strain GHA is a fungus that is used as a pesticide for controlling many kinds of insects. The active ingredient can be used on all food crops and many non-food crops at various outdoor and indoor sites. Residues of the pesticide are not expected to remain on treated food or feed. Available information indicates that use of the pesticide is not expected to have adverse effects on people or the environment.

Many strains of Beauveria bassiana are found worldwide in the soil. They control insects by growing on them, secreting enzymes that weaken the insect's outer coat, and then getting inside the insect and continuing to grow, eventually killing the infected pest.
There are no expected health risks to humans who apply this fungus as a pesticide or who eat crops treated with the fungus. Special precautions are specified for pesticide handlers and for field workers who need to enter treated fields within certain short intervals after pesticide application. These workers must wear respiratory equipment and protective clothing as described on the product labels.
Tests show that the fungus is not toxic to mammals, birds or plants. There is a potential for the pesticide products to harm bees, so the products must not be applied near beehives or where bees are actively hunting for food. If the pesticide products are used as labeled, no harmful environmental effects are expected.
Pesticide products containing Beauveria bassiana strain GHA have been approved since 1995 for use on all food and feed crops and for certain non-food uses. As of November 1999, there were seven approved pesticide products containing this active ingredient.
