Symptoms and damage

Yellowing and distorted leaves, stunted growth and an unsightly black sticky substance on the plant may mean that you have aphids. Aphids feed on a wide range of plants, and in severe cases the plant fails to thrive. As they feed, they secrete a sticky substance, called honeydew, which quickly becomes infested with black sooty mold. They also spread viruses, many of which are incurable..
