Integrated Pest Management
• What is IPM?• Components of an effective IPM program• Advantages of using IPM• Challenges of implementing IPM• New resources available for IPM
What Is IPM?
• An effective and environmentally sensitive approach to pest management based on current, comprehensive information regarding pest life cycles and their interaction with the environment.
• Used to manage pest damage by the most economical means, with the least possible hazard to people, property, and the environment.
4-Tiered Approach to IPM
• Set action thresholds
• Monitor and identify potential pests
• Prevention
• Control
Management Plan
• Selection of plants
• Nutrient management
• Pest management
• Possible control techniques
• Review and update
Know Your Action Threshold
• What is the “action threshold” Pest density at which control measures
should be implemented to prevent economic loss from occuring
• What is the economic injury limit? The point when the economic benefit of treatment is greater than the cost
Pest Identification
• Why is it important?
– Accurate diagnosis of problems
– Appropriate management plans or policies
– Correct treatment measures
Invasive Plants
Yellow Starthistle• Annual• Single yellow flower per
branch• ¾ -1 inch spines radiating
from flower bracts• Grayish-green foliage• “Winged” stem

Invasive Plants
White Bryony• Vine• Small yellow-green or
yellow-white flowers • Pea-sized black berries• Dark green, palmately lobed
leaves• Single curling tendril at each
leaf node
Invasive Plants
Bohemian Knotweed• Shrub• Small white flowers• Hollow, cane-like stems• Heart or spade shaped
leaves• Short, broad based
(triangular) hairs on underside of leaves
Management Techniques
• Cultural •crop rotation•pest resistant varieties•pest-free rootstock•eliminating “pest homes”
• Biological •beneficial insects•grazing•use of pheromones
IPM Advantages
• Slows development of pesticide resistance
• Reduces risk to spray operators and the environment
• Step towards sustainability• Proactive• Site-specific• Business opportunity in
scouting/monitoring
Challenges of IPM Implementation
• More complex than control by chemicals alone
• Requires understanding of pest and beneficial species interactions
• Knowledge of management options
Additional Training
• IPM Training– Live workshops– Webinars (internet-based seminars)
offered through the Schutter Diagnostic Lab and the National Plant Diagnostic Network (www.npdn.org)
– Existing Pesticide Applicator Training programs from MSU and the MDOA
– Urban IPM certification through MSU– First detector training through MSU
Urban IPM Program Objectives• Establish an IPM certification program for urban
landscape and turf professionals• Develop resources for IPM in the urban
landscape, specific to Montana• Train you to be First Detectors for invasive pests• Educate homeowners/consumers in
the basic principles of IPM
Additional Online Resources
