Whiteflies: How to Recognise Damage?
Whiteflies can damage plants in various ways. First of all, they prick the leaves to extract nutrients. This causes the leaves to turn yellow and eventually fall off. Whiteflies also have toxic saliva that can cause a lot of damage to plants. Additionally, the insect can spread viruses. Finally, whiteflies secrete honeydew on the leaves. This makes for an excellent breeding ground for fungi.
