About pesticides

Submitted by on October 21, 2012

Pesticides control pests interfering physically, chemically
or biologically with their metabolic activity and behavior.
Some insecticides act by disturbing the balance of sodium and
potassium in the nerve fibers. Others inhibit acetyl
cholinesterase and produce paralyses. Herbicides may affect
the nutrient transport systems of the plants or can inhibit
photosynthesis.
