Pear IPM Module
Practical IPM plan for pears covering outdoor pear orchards and protected pear systems.
Main focus: pear sucker, aphids, spider mite, scab, Botrytis and canopy airflow.
Main pest risks
| Pest / Disease | Risk | Main trigger |
|---|---|---|
| Pear sucker | Very High | Warm sheltered orchards |
| Aphids | Moderate | Soft growth |
| Spider mites | Moderate | Hot dry weather |
| Pear scab | High | Wet conditions |
| Botrytis | Moderate | Humidity and damaged fruit |
Monitoring plan
Best practical rule: inspect shoot tips and fruit clusters weekly once warm spring growth begins.
| Area | What to inspect |
|---|---|
| Shoot tips | Pear sucker and aphids |
| Fruit clusters | Botrytis and damage |
| Lower leaves | Spider mite |
| Dense canopy | Humidity and scab |
| Orchard floor | Fallen fruit and debris |
Environmental risk
| Condition | Likely issue |
|---|---|
| Warm sheltered canopy | Pear sucker |
| Wet foliage | Scab |
| Dense growth | Humidity pockets |
| Hot dry weather | Spider mite |
Orchard management
Useful practices: - maintain open tree structure - improve airflow - remove fallen fruit - reduce dense shading - maintain pruning hygiene
Key message
Pear IPM depends heavily on airflow, sucker management and fruit hygiene.
