  • Monitoring is done in a systematic manner according to accepted IPM guidelines. Records are kept of all monitoring information collected.
  • Bark of rootstock, trunk and limbs is monitored for San Jose scale, winter moth, woolly apple aphid or borers, where appropriate.
  • Tarnished plant bug is monitored by white visual sticky traps or visual inspection of buds.
  • Leafminers are monitored by foliar inspection for first generation mines.
  • Foliage is sampled for mites and mite predators.
  • Fruit clusters are examined pre-bloom for pug moth and/or winter moth.
  • Fruit is monitored for fresh plum curculio injury following initial cover spray to time additional sprays, if needed.
  • European apple sawfly is monitored by white visual traps.
  • Pheromone traps are used to monitor Oriental fruit moth, codling moth, and oblique banded leafroller, and for determining biofix (first sustained trap catch).
  • Terminal foliage is monitored for aphids and aphid predators.
  • Monitoring for leafhoppers (fruit clusters for white apple LH and rose LH; terminal growth for potato LH) is conducted.
  • Brown marmorated stink bug is monitored with pheromone traps
  • Apple maggot fly is monitored by red sticky spheres that can be either unbaited or baited with an apple-based lure.
  • Fruit and foliage are monitored for codling moth, fruitworm and leafroller larvae or injury, where appropriate.
