Grape growers have a new tool to protect their vines next spring from climbing cutworm chomping at the buds and reducing yields.

pouncelogoThe Pest Management Regulatory Agency (PMRA) recently granted a Minor Use Label Expansion to Pounce® 384EC insecticide for control of climbing cutworm in grapes.

“This is good news for grape growers who now have another solution that protects what they’ve worked so hard to produce at a critical stage in vine growth and development,” said Janet Porchak, Eastern product manager for UAP Canada Inc.

True to their name, climbing cutworms – whose larvae have overwintered – climb up grape vines and feed on the buds and young leaves in the spring. That is when feeding is most damaging, particularly when there is loss of both the primary and secondary bud. If both buds are damaged then grape yields will certainly be reduced since the tertiary bud will not produce fruit from its shoot. Experts recommend an application of an insecticide when bud damage reaches one or two per cent.

“Pounce gives grape growers the peace of mind that the buds swelling on their vines can reach their full potential and produce fruit rather than be cut short by climbing cutworms,” said Samuel Tutt, Canadian development manager, FMC Corporation.

Pounce is marketed in Canada by FMC Corporation and distributed by UAP Canada. In grapes, Pounce is already registered for control of Grape berry moth and Grape leafhopper.

Pounce is a broad spectrum insecticide with low toxicity and good residual activity. It is labeled for ground application in grapes and available in two convenient sizes.

In addition to grapes, Pounce has been successfully used for years by growers to control economically significant insect pests in corn, cereals, canola, potatoes, vegetables, lentils, cole crops, stone fruit, pome fruit, berries, sugar beets and sunflowers.
