OP-9: Integrated Pest Management

Humber's North Campus Arboretum IPM plan is dependent on season and weather. The plan includes the following practices: • Use of dormant oil sprays and selective pruning to remove or limit overwintering pests and diseases. • Identify and monitor known pests and diseases using phenology checklists, landscape reports from OMAFRA and visual inspection previous infestations • Identify beneficial insects, reptiles and amphibians and encourage habitat through planting of native and host plant species, timing of plant cleanup (leaving leaf and plant litter as nesting and overwintering sites) • Physical removal of pests through manual and mechanical means to maintain an acceptable threshold of damage. • Remove of plants that cannot be maintained at an acceptable level and replanting with more resistant types. • Use of insecticidal soaps and other sanctioned plant health additions and strategies such as neem oil, aerated compost tea, correct amounts of organic fertilizers and adequate watering.
