|Tuesday Products: Organic and Biopesticides|
|Written by Heleigh Bostwick Tuesday, 14 May 2013|
The EPA (US Environmental Protection Agency defines the word pesticide as a substance intended to prevent, destroy, repel, or mitigate any pest, including insects, mice and other animals, unwanted plants (weeds), fungi, or microorganisms like bacteria and viruses. When it comes to environmentally friendly pesticides, there are two types: Organic pesticides and biopesticides.
Made with natural ingredients, organic pesticides are used to kill insects and other pests. While organic pesticides may be “all natural” and made without synthetic chemicals, it is important to note that they still can be considered toxic. Some organic pesticides may be highly toxic to specific animals but not to humans. Also of note is that organic pesticides may be harmful to beneficial insects like the ladybugs pictured above eating the aphids (the bad guys), as well as insect pests.
Biopesticides on the other hand, are safer for both humans and the environment and reduce the risks associated with pesticide use because they suppress or prevent rather than destroy pests. Biopesticides are either biochemical such as insect pheromes or microbial, which are derived from microbes such as fungi or bacteria. Milky spore is an example of a microbial bio-pesticide. Biopesticides focus on a specific action rather than a broad one that wipes everything out, persist for less time in the environment, and leave little to no residue behind.
