For best results, apply CheckMate® OLR early in the season, as soon as the first omnivorous leafroller of the season is detected by a BioLure® OLR pheromone trap or by field scouting. Apply at the rate of 100 dispensers per acre. CheckMate OLR dispensers are not affected by irrigation or spray applications. If there are more than 100 trees per acre, evenly distribute the dispensers within the block. Place BioLure OLR monitoring traps before placing CheckMate OLR dispensers. Wash hands when done placing dispensers, traps or lures. Do not handle other types of pheromone lures or dispensers before or after placement without thoroughly washing hands. This product only affects adult male moths and will have no effect on female moths, eggs or larvae. If application occurs following biofix or during the growing season, the orchard must be treated with insecticide treatments that will effectively control hatching larvae until egg laying by previously mated female moths has ceased to occur. In moderate to high insect pressure situations, supplemental insecticide applications during the season may be necessary to provide adequate protection to developing fruit. These supplemental insecticide applications should be made based on trap monitoring, field scouting, and appropriate degree-day models for the local growing area and must be timed to control emerging larvae. Monitor insect infestation with traps and by visual inspection of shoots and fruit. Early placement of BioLure OLR monitoring traps is recommended along with careful field scouting. Monitor treatments carefully for other insect pests such as oriental fruit moth. Note: This product does not control raisin moth. Careful scouting and insect identification must be made to properly differentiate between OLR and raisin moth. Raisin moth must be controlled in susceptible crops. CheckMate OLR is best used to control low populations of omnivorous leafroller and prevent their increase.
