Transcript Integrated Pest Management

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.
