Biopesticides contain naturally occurring substances that control pests. Substances that control diseases in this category include potassium bicarbonate, hydrogen dioxide, phosphorous acids, plant extracts, and botanical oils.
Microbial biopesticides contain microorganisms as the main active ingredient that function as biological control agents, affecting the pathogen directly or indirectly through the compounds they produce or by stimulating specific plant responses.
Plant-incorporated protectants (PIPs) are the least common type of biopesticide. Biopesticides also exist for the management of weeds, insects, and nematodes.
Several factors can affect performance of biopesticides, or any product used for disease control.
However, biopesticides are generally less toxic to the user and are non-target organisms,
Therefore, making them desirable and sustainable tools for disease management.
Bio-pesticides are usually inherently less toxic than conventional pesticides.
Biopesticides often are effective in very small quantities and often decompose quickly, resulting in lower exposures and largely avoiding the pollution problems caused by conventional pesticides.
