Complete spray coverage is necessary to control this mite. Use no less than 25 gal water per acre. Do not graze livestock in treated orchards. Thiodan will suppress light populations of winter moth. Thiodan drift to the orchard floor will kill earthworms.
Pheromone traps are available to detect and monitor flight activity of filbertworm moths.
They have been successfully used to time cover sprays. Apply insecticides 8-12 days after filbertworm moths emerge in your area. A second application usually is necessary in 2-3 weeks. A repeat spray may be necessary if heavy rainfall occurs a day or two after application and the label allows it. Second and third sprays may be necessary and should be made if pheromone traps continue to catch moths 2-3 weeks after a spray.
