Pesticide use dropped in California for a fourth consecutive year in 2009, Department of Pesticide Regulation Director Mary-Ann Warmerdam announced. Nearly 156 million pounds of pesticides were reported applied statewide, a decrease of nearly 8 million pounds – or 5 percent – from 2008.
Pesticide use in production agriculture fell by 5.1 million pounds and in most other categories as well, including post-harvest treatments, structural pest control and landscape maintenance. Reports are mandatory for agricultural and pest control business applications, while most home, industrial and institutional uses are exempt.

“The winter and spring of 2009 were relatively dry, which probably resulted in less weed and disease pressure,” Warmerdam said.
“Fumigants showed the greatest drop in pounds and acres treated, which also may be due to increased environmental and regulatory concerns.”
Fumigants are gaseous pesticides injected into soil before planting to control weeds, soil-borne pests and diseases. They are primarily used on strawberry, carrot and processing tomato fields. Fumigants are also used for structural pest control of wood-destroying insects.
