Flea Beetle Damage in the Vineyard

Flea beetles are an early season pest in the vineyard.  Both the adults and larvae are present during the Spring.  The best time to control this pest is at bud swell, as if not controlled they will continue to cause problems later as larvae.  Several products can be used to control flea beetles in the vineyard, such as Sevin, Danitol, Baythroid, etc.  See the photo below for the kind of damage the larvae can inflict on leaves (but also blooms).  Adult beetles will feed on swelling primary buds, and this is the more serious type of damage that occurs.  If this is a problem, they should be controlled to prevent a reduction in shoots (and crop) in the following years.
