Pest Management

• General symptoms: Sucking pests cause wilting, stunting, curling or distortion of new growth, spots or stippling of the leaf surface, or a sticky substance or black fungal growth on the upper leaf surface. Chewing pests cause holes in leaves, silvering of leaf tissue, complete removal of leaf tissues and burrowing in or around plant stems, branches or trunks.
