Using a variety of pest control methods that minimize env. disruption and pesticide use Researching & monitoring pests and targeting methods to specific pest life cycles

(Bringing in a natural predator or parasite to control the pest) Can include actually purchasing & spreading the control organisms in fields, or building homes for them/planting habitat they need to attract them naturally

Spiders for many pest insects Ladybugs for aphids Parasitic wasps for caterpillars

Many pests prefer one specific crop or crop family. They lay eggs in the soil, so when larvae hatch, they have preferred food source.

planting a different crop each season) can prevent pests from becoming established since it disrupts their preferred food choice

Also disrupts weed growth since diff. crops can be planted at different times, preventing bare soil from being taken over by weeds

Push-pull” system can be used Push” plants emit volatile chemicals that naturally repel pests away from crop

Pull” plants emit chemicals that attract moths to lay eggs in them, instead of crop Can provide habitat, or “pull” plants that emit chemicals that attract natural pest predators

Reduces death & mutation of non-target species from Ex: intersex frogs (atrazine) Eagle death (DDT) Bee die offs (glyphosate)

Reduces effects on human consumers of produce Ex: many pesticides are carcinogens (cause cancer) Reduces contamination of surface & ground water by agricultural runoff with pesticides

Can be more time consuming & costly than just crop dusting pesticides Ex: researching specific pests & planting numerous species of crops

Term	Definition
IPM Basics	Using a variety of pest control methods that minimize env. disruption and pesticide use Researching & monitoring pests and targeting methods to specific pest life cycles
Biocontrol	(Bringing in a natural predator or parasite to control the pest) Can include actually purchasing & spreading the control organisms in fields, or building homes for them/planting habitat they need to attract them naturally
Biocontrol examples	Spiders for many pest insects Ladybugs for aphids Parasitic wasps for caterpillars
Crop Rotation	Many pests prefer one specific crop or crop family. They lay eggs in the soil, so when larvae hatch, they have preferred food source.
Rotating crops	planting a different crop each season) can prevent pests from becoming established since it disrupts their preferred food choice
Rotating crops	Also disrupts weed growth since diff. crops can be planted at different times, preventing bare soil from being taken over by weeds
Intercropping	Push-pull” system can be used Push” plants emit volatile chemicals that naturally repel pests away from crop
Intercropping	Pull” plants emit chemicals that attract moths to lay eggs in them, instead of crop Can provide habitat, or “pull” plants that emit chemicals that attract natural pest predators
Benefits of IPM	Reduces death & mutation of non-target species from Ex: intersex frogs (atrazine) Eagle death (DDT) Bee die offs (glyphosate)
Benefits of IPM	Reduces effects on human consumers of produce Ex: many pesticides are carcinogens (cause cancer) Reduces contamination of surface & ground water by agricultural runoff with pesticides
Drawbacks of IPM	Can be more time consuming & costly than just crop dusting pesticides Ex: researching specific pests & planting numerous species of crops
