  • Biopesticides are naturally occurring substances, such as microbes, Bt bacteria, plant extracts, fatty acids or pheromones. Their use is growing rapidly worldwide, and they are in demand for their value in IPM programs to enhance yields and quality along with their low impact on the environment.
Currently, the EPA recognizes three major classes of biopesticides:
  • Microbial pesticides consist of a microorganism (e.g., a bacterium, fungus, virus or protozoan) as the active ingredient used to control pests. The microorganism may occur naturally, be dead or alive, or be genetically engineered. Microbial pesticides can control many different kinds of pests, although each separate active ingredient is relatively specific for its target pest[s]. For example, there are fungi that control certain weeds, and other fungi that kill specific insects.
  • Biochemical pesticides are naturally occurring substances, such as plant extracts, fatty acids or pheromones, that control pests using a nontoxic mode of action to the pest. Conventional pesticides, by contrast, are generally synthetic materials that directly kill or inactivate the pest, most frequently by attacking the nervous system. Biochemical pesticides, while nontoxic, can be lethal such as clays that suffocate insects, anti-feeding compounds that cause starvation, or vinegar that kills plants. Other biochemical pesticides include substances such as insect sex pheromones that disrupt mating, repellents that protect plants from deer or insect pests, and various scented plant extracts that attract insect pests to traps.
  • Plant-Incorporated-Protectants (PIPs) are pesticidal substances that plants produce from genetic material that has been added to the plant, such as corn and cotton. Scientists have taken the gene for the Bt pesticidal protein, and introduced the gene into the plant’s own genetic material. The plant, instead of the Bt bacterium, manufactures the substance that destroys the pest. The protein and its genetic material, but not the plant itself, are regulated by EPA.
  • Biopesticides offer additional benefits, such as complex and novel modes of action for resistance management to extend the product life of conventional pesticides. They also add flexibility in a traditional farming operation with reduced pre-harvest intervals to manage residues for exported produce, and shorter field reentry times for workers, which reduces labor costs.
