Pests
Whiteflies on Cucumber Plants
Commonly affects: Cucumis sativus (Cucumber)

Potential Causes
- 1Warm conditions, especially in greenhouse or protected growing
- 2Introduction from infected transplants or nearby host plants
- 3Whiteflies thriving in still, humid air
Solution Steps
- 1Use yellow sticky traps to monitor and reduce adult populations
- 2Spray the underside of leaves thoroughly with insecticidal soap
- 3Introduce parasitic wasps for greenhouse biological control
- 4Improve airflow around plants
Prevention Tip
Inspect new transplants for whiteflies before introducing them to your growing area, since infestations establish quickly.
