The Environmental Protection Agency has registered Requiem Insecticide from AgraQuest Inc. of Davis, Calif., to control soft-bodied insects in all life stages.

State registrations are pending.

The product, which is an extract of Chenopodium ambrosioides near ambrosioides or American wormseed, contains terpene compounds. It controls insects by degrading the exocuticle. At the same time, it destroys the trachael lining by localized fumigant activity.

It has little or no effect on beneficials.

Requiem is registered on a wide variety of crops, including tomatoes, peppers, Brassicas, strawberries, bulb vegetables, grapes and selected leafy greens. It targets whiteflies, web-spinning mites, aphids and thrips, according to a new release.

The product has a four-hour re-entry interval and a zero-day pre-harvest interval. It is exempt from tolerances, so growers won't have to be concerned about residue on exports.

The recommended rate is a maximum of 2 quarts per acre. Based on field trials, adding a surfactant has little or no effect on efficacy.
