Integrated Pest Management

Minimizes Environmental Damage, Maximizes Production

Agent and farmer standing in a wheat field.Last year, an unknown pest threatened more than 25,000 acres of wheat along the Eastern Shore. Bill Shockley, agriculture and natural resources Extension agent in Northampton County, contacted the appropriate specialist, who identified the pest as winter grain mite, known for its rapid dispersion. Within 24 hours, 150 key producers and agricultural suppliers in the area had received relevant educational materials about this mite and within two days, more than 1,000 acres of wheat had been treated for the pest. Because of the early remedial action on the part of Virginia Cooperative Extension agents and specialists applying integrated pest management (IPM) principles, the Eastern Shore’s wheat crop was spared a potential economic hardship.

Since at least the 1970s, Extension has offered IPM-based recommendations to reduce pest populations and bring their damage down to acceptable levels. “With IPM, we combine all possible ways to fight pests, including preventative, sanitary, and cultural measures,” says Ames Herbert, pest management Extension specialist and Virginia IPM program coordinator. “IPM may be information-intensive, but people have learned that it is the best solution both environmentally and economically.” Read the full story in Solutions.

New insecticide to help tree fruit industry fight stink bug

Brown marmorated stink bug

A native of East Asia, the brown marmorated stink bug has no natural predators in North America.

Virginia’s fruit industry has a new weapon in the fight against the brown marmorated stink bug, or Halyomorpha halys. On June 29, the U.S. Environmental Protection Agency (EPA) granted an emergency exemption to use the insecticide dinotefuran to control the stink bug on stone and pome fruits in Virginia and six other states.

Chris Bergh, tree fruit and grape specialist for Virginia Cooperative Extension and associate professor of entomology at Virginia Tech, prepared the application for the pesticide’s use as part of Extension’s larger effort to ward off the stink bug in Virginia.

“The exemption will allow stone and pome fruit growers in a seven-state region to use this pesticide,” Bergh said.

The Virginia Department of Agriculture and Consumer Services (VDACS) submitted the application to allow for unregistered use of the pesticide until Oct. 15, the end of harvest season. According to a VDACS announcement, Section 18 of the Federal Insecticide, Fungicide and Rodenticide Act authorizes the EPA to grant exemptions for pesticide use for a limited time in the event of an emergency.
