As toxic and persistent agricultural chemicals make headlines again, organic farmers have a message to share with concerned consumers. Previously a recent National Academy of Sciences study suggested that one out of four developmental and behavioral problems in children may be linked to genetic and environmental factors, including exposure to lead, mercury and organophosphate pesticides. A growing number of North American farmers have already taken steps to minimize the use of, and consumers' exposure to, toxic and persistent pesticides. These growers have adopted organic agricultural practices that maintain and replenish soil fertility without the use of these materials.
Organic farmers have the Earth's welfare in mind.
In its report, CDC noted that organophosphate pesticides account for approximately half of the insecticides used in the United States. An estimated 60 million pounds of organophosphate pesticides are applied to about 60 million acres of U.S. agricultural crops annually, and an additional 17 million pounds are used per year for nonagricultural uses, such as in household pest control products and in lawn and garden sprays. Organophosphates are not allowed in organic agriculture. Instead, organic growers use biological and cultural practices as their first line of defense against pests. Methods used include crop rotation, the selection of resistant varieties, nutrient and water management, the provision of habitat for the natural enemies of pests, and release of beneficial organisms to protect crops from damage.
