Because of their unique modes of action and/or their short residual effectiveness, coverage and timing of application of biopesticides are absolutely critical for effective control. In some cases biopesticides have been tried when all other materials have failed, which is using them in a no-win situation. They are not materials that can be used to clean up a problem that has gotten out of hand. Used more in conventional farming Biopesticides can be used successfully in a range of situations. Many biopesticides are compatible with conventional pesticides and can be tank mixed. They can also be used in rotation with conventional pesticides to reduce the possibility of the develop- ment of resistance of important conventional materials. Biopesti- cides are useful in situations where residue management of spray materials is an issue.
