CheckMate OFM-XL is a patented, pheromone-based product designed to disrupt mating of adult oriental fruit moths. CheckMate OFM-XL is a membrane dispenser system that emits synthetic oriental fruit moth sex pheromone. Used as directed, this product saturates the orchard environment with the female sex pheromone so that individual males cannot locate female moths ready to mate. This product emits pheromone over an extended period of time (up to 90 days) providing continuous mating disruption and suppression over several generations of oriental fruit moth. This system was designed for use in peaches and nectarines. CheckMate OFM-XL's long field life provides the lowest cost of control per hectare per day. The benefits of using CheckMate OFM are:
Use and Application
Apply CheckMate OFM-XL early in the season, as soon as the first oriental fruit moth of the season is detected by a pheromone trap or by field scouting. Apply at the rate of 270 per hectare. Place dispensers in the upper one-third of the canopy, preferably on the south side of the tree. If there are more than 270 trees per hectare evenly distribute the dispensers within the block. If there is a prevailing wind, apply one dispenser to every tree on the upwind side of the orchard and then evenly distribute the remaining dispensers in the block. Place monitoring traps before placing CheckMate OFM 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. Monitor insect infestation with traps and by visual inspection of shoots and fruit.
Early placement of monitoring traps at a rate of one trap for every 4 hectare is recommended along with careful field scouting. Monitor treatments carefully for secondary insect pests such as peach twig borer. 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.
Monitoring Information
Monitoring adult populations of oriental fruit moth with pheromone traps is strongly recommended to provide baseline information on population density and to improve timing of mating disruption and/or insecticide treatments. Good monitoring is an important part of achieving optimum results. Visual inspection of foliage and fruit for larval feeding is also needed at frequent intervals after treating to implement supplemental control strategies if needed. Place one phermone trap per 4 hectasres with a minimum of two traps per block. Position traps in the upper portion of the canopy. When the first oriental fruit moth is caught in a trap, CheckMate OFM dispensers should be applied. Place additional traps on borders that are most subject to migration from adjacent fields or host crops.
Clean trap bottoms at least twice weekly. Replace lures at least every two months and trap bottoms more often if they become dirty or covered with dust, spray material, moth scales or other insect body parts. Do not handle other types of insect lures before or after placement of traps without thoroughly washing hands. Pheromone traps should not be utilized as the only method of monitoring the degree of crop protection being afforded by CheckMate OFM. Effective pheromone mating disruption treatments will shut down trap catches of male moths. Pheromone lures will not detect migration of oriental fruit moth females from adjacent fields or infestations of peach twig borer. The use of bait traps (terpinyl acetate) and frequent field inspection of fruit is strongly recommended.
