Environmental favorable factors for pests/Diseases:
- Temperature: Jassids are warm-blooded insects and prefer temperatures between 20-30°C (68-86°F) for optimal development and activity.
- Humidity: Dry conditions reduce the chance of fungal diseases that can harm jassids and allow them to move more freely on the plant.
Symptoms of Pest/Disease:
- Yellowish stippling: Tiny yellow dots appear on the upper surface of leaves, marking the feeding sites of jassids.
- Stunted growth: Less common, but jassid feeding on tender stems can hinder the overall growth of the plant.
- Dieback: In severe cases, stem feeding can lead to dieback of branches or even the entire plant.
