Mainspring (Syngenta): Bars Pests From Feeding And Deters Their Establishment.

    Mainspring is a new systemic insecticide with broad spectrum activity against a wide array of chewing and sucking pests such as caterpillars, thrips and whiteflies (B and Q types). It contains the new active ingredient cyantraniliprole (IRAC Group 28), which causes paralysis, feeding inhibition and death. Mortality is observed within two to four days.

    “Mainspring offers a new class of chemistry for the ornamental market that growers can use for systemic protection against key ornamental pests,” says Syngenta’s Field Technical Manager, Nancy Rechcigl. “It is best used early in production to keep insect populations from building to damaging levels; it stops pests from feeding and keeps them from establishing in the crop.”

    Mainspring can be applied as a foliar spray or as a drench and has a four-hour REI (re-entry interval). Rechcigl says good control has been observed when foliar sprays are applied using a rate of 4 to 8 fluid ounces/100 gallons on a 14-day interval, while a drench application provides residual control for five to six weeks, depending upon the pest. The product does not negatively affect predator and parasitoid populations when used according to the label.

    Syngenta has also registered Enfold insecticide for use on herbaceous and woody ornamentals grown in commercial outdoor production. It contains the active ingredient emamectin benzoate (IRAC Group 6) and has activity across a wide array of lepidopteran pests, and it provides suppression of the Liriomyza leafminer, spider mites and pear psylla.
