Dow AgroSciences announced Monday that the U.S. Environmental Protection Agency will allow peanut growers to use Intrepid 2F.

The supplemental product label approved by the EPA allows peanut growers to apply Intrepid 2F when the first signs of feeding damage appear or when the pests exceed threshold levels.

"Beet armyworms are sporadic pests that feed on peanut foliage and are often difficult to control," says Tom Linnen, a Dow marketing specialist. "Intrepid 2F allows growers to target these armyworms without flaring populations of mites or aphids."

Dow touts Intrepid 2F as an effective tool in multiple crops against a broad spectrum of lepidopteran insects, such as beet armyworm, yellowstriped armyworm, saltmarsh caterpillar, soybean looper and fall armyworm. According to the company, Intrepid 2F insecticide does not disrupt beneficial insects, mites or pollinators, which fits Integrated Pest Management programs.

"Many producers use pyrethroids for late-season insect control, but Intrepid 2F will offer growers a unique residual formulation that provides control for seven to 10 days — or longer," says Mitch Binnarr, sales representative for Dow AgroSciences.

In peanut fields, Dow recommends Intrepid 2F be applied at a minimum rate of 10 gallons per acre by using conventional ground application equipment. Guidelines call for proper equipment calibration to ensure uniform coverage of infested areas. Growers can make up to three applications of Intrepid 2F per calendar year, with a re-treatment interval of seven days.
