Survey Ranks Cormoran Top SWD Insecticide
New tool for berry growers
Survey Ranks ADAMA Canada’s Cormoran Insecticide Best
WINNIPEG, January 17, 2022 – A new survey shows ADAMA Canada’s Cormoran® Insecticide to be the preferred choice against an invasive and prevalent pest that has plagued Canadian berry growers over the last decade.
The spotted-wing drosophila (SWD) is a vinegar fly of East Asian origin causing damage to many soft skinned fruit crops. SWD pierces seemingly healthy fruit and lays its eggs. The eggs hatch in about three days. The larvae feed on the fruit and emerge as adults after as few as six days or as many as 28.
Cormoran delivers two modes of action for resistance management and rapid knockdown of all damaging stages of target insects as well as extended residual control. Cormoran is registered for use on apples, bushberries, including blueberries, brassica vegetables, peppers, potatoes, stone fruit, strawberries, alfalfa and sweet corn.
“As an insecticide, Cormoran controls many insect pests but does not harm plants,” said Cornie Thiessen, general manager at ADAMA Agricultural Solutions Canada. “It controls all stages of the SWD lifecycle. It’s a combination of two modes of action that work well together by providing fast knockdown and control of adults, larvae and eggs.”
With insecticides being a key management tool for SWD control, entomologists conduct research trials every year to help provide growers with the best possible insecticide recommendations.
In a recently released survey—funded by the USDA National Institute for Food and Agriculture through the Specialty Crop Research Initiative—American entomologists ranked available insecticides.
Based on the survey, ADAMA’s Cormoran® is the preferred SWD insecticide available to berry growers. Since its introduction to Canada in 2020, Cormoran, a broad-spectrum insecticide with multiple modes of action, has demonstrated serious insect protection, including its control of SWD in the bushberry crop group. Cormoran’s chemical makeup includes novaluron and acetamiprid.
Researchers predicated survey results on their own research as well as the experience of growers from their regions, then ranked the insecticides for their combined control of SWD adults and larvae.
ADAMA’s research and development team in Israel created Cormoran’s formulation and produced the product in Georgia (US). It then tested it across Canada to develop proof points and customize the label for Canadian use.
Researchers surveyed entomologists from 10 states including California, Oregon, Washington, Michigan, Maine, New Jersey, New York, North Carolina, Georgia, and Florida, ranking SWD insecticide performance from 0 (ineffective) to 4 (excellent).
ADAMA does not expect supply chain interruption to affect Cormoran production, as the company produced the insecticide in the US ahead of the season.
