- 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.
