Chapter 2- Integrated Pest Management Flashcards
IPM
Aims to prevent pests from becoming a problem effectively through an environmentally sound manner
Elements of IPM
- Prevention
- Identification
- Monitoring
- Thresholds
- Treatment
- Evaluation
Prevention
-Select resistant plants
-Manage growing conditions
-Eliminate food sources
-Prevent access
Identification
Is there a pest problem and which pest is causing the damage? Learn about the pests biology
Do you know the…
-Name of the pest
-Life cycle
-Best time to treat
-Number of treatments needed
-Beneficial organisms related to pest
Monitoring
Provides detailed information about pest population. Make sure to take records of counts and observations
Things to check for in monitoring
-Damage
-Pest count
-Weather conditions
-Pest’s life stage
-Host’s stage
-Beneficial organism presence
Visual inspections
A careful look for signs of pest problems or conditions that promote pests. Done regularly
Counting and measuring
Provides more numerical information about pest populations and the levels of damage
Determine number of samples needed
Take average of sample of 10 then compare it to the average of a sample of 40. If they are within 10-20% then we can use the smaller sample
5 indicators a visual inspection looks for
- Presence of pest and beneficial species
- Damage
- Growing conditions
- Plant health
- Conditions that attract pests
Injury & action thresholds
Interpreting information and making appropriate decisions
The injury threshold
The point where a pest causes unacceptable injury or damage. Justifies treatment
The action threshold
The point at which treatment should be started to prevent the pest population from reaching the injury threshold
Treatment
The decision has been made to treat and manage a pest problem
Cultural treatments
Treatments that can prevent pests from developing or spreading. They attempt to disrupt the pest life cycle or make the environment less favourable
Mechanical/physical treatment
Mechanical or physical treatment involves the use of equipment, barriers etc. to prevent the spread or to reduce populations
Biological treatments
Uses a natural enemy of the pest to reduce population. Eg. releasing a predator or using grazing animals to control weeds
Behavioural treatment
Takes advantage of a pests biology and to manage the population. Eg. releasing sterile male insects or synthetic pheromones
Chemical treatment
The use of pesticides
Evaluation
At the end of the treatment process you evaluate if the results were good
