Syngenta, OHP Offer Improved Insect Management Tools

Whitefly adultBoth Syngenta and OHP have made label updates to two of their insecticides that expand how they can be used in the greenhouse.

OHP recently made a key formulation change to its Ancora Microbial Insecticide that is designed to make spray applications easier in a greenhouse and nursery.


Listed by the Organic Materials Review Institute and approved for organic production, Ancora contains a naturally occurring fungus that infects both foliar and soil-dwelling pests such as whiteflies, thrips, aphids, leafminers, spider mites, grubs, and other pests.

The new Ancora is formulated on a different carrier that allows the product to mix more readily in water for easier sprayer application.

“The new Ancora is formulated on a diatomaceous earth granule, which will make it easier to mix and then move through spray equipment without clogging filters,” says Dr. Carlos Bográn, OHP Manager Technical Service.

Growers using Ancora through a hydraulic sprayer can mix in water and spray.

“We still recommend growers using Ancora through a fogger allow the product to decant in water for 20 to 30 minutes before pouring in a tank and spraying,” Bográn says.

The active ingredient in Ancora —Isaria Fumosorosea Apopka 97 strain — provides fast broad-spectrum activity on both foliar and soil insects in the greenhouse, nursery, and landscape markets.

Ancora may be used on vegetables, herbs, certain fruits, and other crops.

Ancora carries a 4four-hour Restricted Entry Interval (REI) and Caution signal word.

Endeavor Insecticide From Syngenta Now Labeled for Use on Vegetables Grown for Transplant

Endeavor insecticide from Syngenta is now approved for use on vegetable plants grown for consumers. This includes cucurbits, eggplant, peppers, tomatoes, brassica, and leafy vegetables. The expanded label also includes the addition of drench applications for ornamentals. Endeavor offers targeted control of whiteflies and aphids, two of the most common insects greenhouse and nursery growers face.

“The unique active ingredient and targeted protection offered by Endeavor make it a valuable tool for integrated pest management programs, especially those involving biological control agents,” says Laurie Riggs, Insecticide Brand Manager, Syngenta. “With the addition of vegetables to the label, growers who have trusted Endeavor for many years to protect their ornamentals can now expand its use to their vegetable transplants, without disrupting existing programs.”

Endeavor features a novel mode of action in IRAC group 9B, which quickly stops aphids and whiteflies from feeding, reducing the threat of virus transmission and eliminating populations.

Endeavor is highly compatible with predators, parasites, and other beneficial mites and insects. It is a proven solution to incorporate with beneficial insects to help control two problematic pests in production.

“With both translaminar and systemic movement, Endeavor has proven to offer long residual activity,” said Nancy Rechcigl, Technical Services Manager for Ornamentals, Syngenta. “Spray applications generally provide 14 to 21 days of control, and now with drench applications added to the label, protection can be extended six to seven weeks.”

Endeavor is also labeled for use on landscape ornamentals, non-bearing fruit and nut trees in nurseries; Christmas trees; ground covers; and ornamental plants in greenhouses, lath, and shadehouses, and interiorscapes.
