Comments Requested for Special Onion Pesticide Registration
Wisconsin Ag Connection - 06/14/2013
The public can comment until June 21 on proposed special registration of a pesticide to be used to control insects and nematodes on dry bulb onion crops. The special registration proposed by the Department of Agriculture will allow growers to use Vydate L on dry bulb onions to control the insect called onion
thrips and the microscopic worms called stubby root nematodes. Thrips adults and larvae feed on the onion leaves, and may produce up to four generations in a season. They may reduce yields up to 50 percent. Thrips has become resistant to other pesticides currently registered to control it. This registration will allow growers to use Vydate L in rotation with other registered pesticides.
Vydate L contains the active ingredient oxamyl and is registered by E.I. du Pont de Nemours and Co., Wilmington, Del. It is registered for use on dry bulb onions in other states, but not Wisconsin.
The preliminary environmental assessment indicates that the proposed amendment will not require a full environmental impact statement. This special pesticide registration will expire December 31, 2017.
