Mites affecting African violets can be separated into 3 classes based on the damage they bring. Those classes are chewing mite, sucking mites and nuisance mites.
Damage caused by chewing mites commonly takes place quickly and is discernible straightaway. Those mites need to be wiped out as quickly as they're discovered. Signs of chewing mites include:
1. Drooping of plant (stem or crown damages)
2. Broke up leaves or flower buds
3. Hollows in branches or flower petals
4. Stained locations on the surface f branches or flower petals.
Sucking mites stick in the mouthparts onto plant tissue and absorb out the succuses. A few put in harmful chemical compounds into the plant and a few are able of transferring particular plant diseases. The signs of sucking mites frequently go unobserved for a time period. It permits the mites to become somewhat established and improve in quantities, leading in substantial plant damage. The signs of sucking mites are:
1. Drooped visual aspect
2. Invasion of honeydew
3. Curled or stunted leaves
4. Discolored leaves
5. Necrotic (defunct tissue) places in leaves.
Nuisance mites bring no damage. They're believed mites just because their invasion isn't wanted. These insects fast-flying or hop-skipping about detract from a attractive centrepiece or a specimen flower in exposition. A few nuisance mites reproduce quickly and frequently are discovered in significant quantities. These plagues are quickly wiped out with cautious handling and correctly chosen insecticides.
