Biopesticides

Back to index
1.  Biopesticides - Biopesticides (also known as biological pesticides) are certain types of pesticides derived from such natural materials as animals, plants, bacteria, and certain minerals. Biopesticides fall into three major categories: (1) Microbial pesticides, (2) Plant-pesticides, & (3) Biochemical pesticides. EPA Office of Pesticide Programs site. At the end of 1998, there were approximately 175 registered biopesticide active ingredients and 700 products. EPA Office of Pesticide Programs site.

2.  Biopesticides and Pollution Prevention Division (BPPD) - EPA Office of Pesticide Programs. The BPPD is responsible for the regulation of all biopesticides in the United States. This website includes a definition of biopesticides, regulatory activity, active ingredients, Federal Register notices, press releases, publications and a related Internet resources section. The regulatory activities section breaks down biopesticides regulations by all types including active ingredient approvals, tolerance applications, and experimental use applications. Fact sheets are also available from the home page.

3.  Biopesticides Active Ingredient Fact Sheets - EPA.

4.  Biopesticides - This site is on the IR-4 (Minor Crop Pesticide Registration program) Home Page. When you get to the IR-4 Home Page, click on Biopesticides (half way down the yellow list at the left), then click on Listings. This is a slowly developing list of biopesticides registered on various crops.

5.  Pest Management Resource Center's Biopesticide - UK site. The Pest Management Resource Center Biopesticide website provides technical and educational information on biopesticides including what biopesticides are available and where they can be obtained within the United Kingdom. The website also has information on related books and journals and links to related websites.

6.  Bacillus thuringiensis Fact Sheet - National Pesticide Telecommunications Network. Produced by Oregon State University.

7.  Biological Control (Florida) - ONE WAY TO MANAGE INVADING NON-NATIVE PLANTS in Florida's watery systems is to use biological control agents such as insects, fish and pathogens. Biological control is the purposeful introduction of natural enemies by scientists and environment managers as a means to weaken and suppress invading plants.
