Abstract

Studies indicate that the best approach to control of the omnivorous leaf roller at present is field sanitation and chemical treatment if necessary. Early French plowing and disking should forestall damage in vineyards not yet infested. Where infestation already has occurred, removing all mummified clusters from the vine along with the French plowing and disking will be necessary. A standard lead arsenate spray just prior to fruit formation looks promising in tests but further research is needed. Insecticide treatments may be needed later in the season where sanitation practices are not used, or have failed to provide sufficient control.
