Integrated Pest Management
What is Integrated Pest Management (IPM)
• Pest management strategy using all available strategies to control pests in a responsible and economical way.
• BMP Best management practice– Use science and practical methods to
optimize crops and minimize environmental impact
IPM
• Studies show that multiple control methods are essential.
– Resistance to methods is possible– Similar to antibiotics resistance
Economical injury level/Economic threshold
• When the control method costs less than the crop loss
Aesthetic Injury Level
• Significant loss to the plants beauty requires control methods
Scouting
• Searching the crop/landscape for pest damage and pests.
Benefits of IPM
• Cheaper costs in pesticide
• Save time and labor costs
• Less disease/pests/weed/resistance
Benefits Continued…
• Less impact on the environment
• Less cancer causing chemicals
What is a Pest?
• Animal that causes injury or loss to a plant– Insect– Rodent– Nemetodes (worms) not earthworm– Snails/Slugs– Other mammals including deer and Raccoons
What is a Disease?
• A negative effect cause by– Virus– Bacteria– Fungus
Weeds
• Any plant growing where it is not wanted– Cause competition– Unsightly– Can harbor other pests and diseases
Insects
• Exoskeleton
• Reproduce quickly and have lots of offspring.
• This leads to pesticide resistance
There are two different types of mouthparts
Insects can effect plants in two different stages of life
• Immature
• Adult
Insects go through metamorphosis
• Complete
• Incomplete

Plant disease
• Also known as a pathogen– Infectious: Caused by a living thing such as
virus, fungi and bacteria. – Noninfectious: (not pathogens) Caused by
non living things in the environment such as overwatering, nutrient deficiencies, air pollution.
Disease Triangle
Disease Triangle Explained
• Take away one of the factors in the triangle and the disease cannot attack.
Weeds
• Broadleaf: Weeds that have big leaves such as dandelions.
• Grass weeds: Weeds that look like grass ie crabgrass.
Weeds
Annual: die every year
Perennial: Come back every year like a tree
Biennial: Plant lives for two years
Weeds
• Parasitic plants: Mistletoe
IPM Solutions
• Sanitation: Keep it clean– Remove weeds– Insects and disease can be found in left over
plant material and weeds– Remove plants from last year if possible
IPM Solutions
• Cultural/physical controls: these physically prevent the problems from getting to the plants.– Don’t let them in– Remove bad plants– Promote healthy growth– Good air circulation– Physical removal– Monitor/Scout
• Use sticky traps
IPM Solutions
• Biological Control– Microbial, parasitic, or predators– Whitefly, catapillar and aphids can be
controlled with bacteria– The bacteria is a natural disease of those
insects. It is like germ warfare
IPM Solutions
• Biological Control cont…– Parasitic organisms – Wasps lay their eggs in the whitefly larvae
and eat them from the inside out
IPM Solutions
• Predatory organisms (can be released) Known as beneficial– Beetle attacking whitefly– Mite killing thrips– Lady bugs eating aphids– Snakes, hawks, cats eating mice
Make sure you don’t kill beneficial insects
IPM Solution
• Chemicals– Know as pesticides (insecticide, rodenticide,
molluscicide, fungicide, herbicide)– Used safely– Used only when needed
Conclusion
• Integrated Pest Management (IPM) uses all available methods to control pests
• A healthy environment and healthy plant leads to less diseases and pests.
