Spider mite feeding can cause numerous yellow or white tiny granulated spots on tomato leaves. The infestation mostly occurs under hot and dry conditions.

Spider mites are very tiny and can be seen on underside of the leaves. During heavy infestation spider mites can be seen all over the plant.

Spider mites suck the juice form the plant and feeding sites show symptoms of yellow blotching. These sections may turn brown and dessicate later.

The underside of the leaves also have yellow discoloration or bronzing or appearance of sandblasting. The plants may turn yellow and leaves may drop exposing fruits to sunscalding.

Under severe infestation from spider mites webbing can be seen on leaves. Severe bronzing of leaves can happen at this stage which could significantly affect yield.
