Growers of agricultural crops across the nation rely on chlorpyrifos’ benefits to protect food and fruit crops from damaging pests. Farmers, technical advisors, agronomists and agricultural pest control professionals favor chlorpyrifos products because they are effective, relatively inexpensive, and have a broad spectrum of activity against many insect pests when compared to alternative products.

Insecticides, such as chlorpyrifos, provide important protection for our food supply and thus safeguard farm and consumer economy:

Insecticides enable U.S. farmers to produce and harvest greater marketable yields than would otherwise be possible. By mitigating the effects of crop-feeding insects, U.S. farmers produce 144 billion pounds of additional food, feed and fiber and reap $22.9 billion in farm income increases. Growers in California benefit the most from the use of insecticides ($7.5 billion/year), followed by [growers in the states of] Washington and Florida ($2.8 and $2.5 billion/year, respectively)….Before the use of insecticides became widespread, insects consumed about 50% of the nation's crops.1

As the population continues to grow and global resources continue to shrink, chlorpyrifos and other insecticides will continue to play an important role in effective insect management strategy.

Explore this section to learn about the most important crops protected by chlorpyrifos, as well as the key areas in the U.S. where it’s used.

Grower Perspective

"Tart and sweet cherries are important crops in Michigan. The state grows 75 percent of the nation’s tart cherries, and we have 7,500 acres of sweet cherries in production. [B]ased on chemical trials…we can safely say that [chlorpyrifos] is currently the only registered insecticide that provides reliable control of the borer complex… Without chlorpyrifos, the Michigan cherry industry would suffer tremendous losses in production, yield and orchard acreage."
