Adults and larvae feed on the sap of the plant, when they dehydrate it, a secondary infection joins - a black fungus. As a result, tomato plants lose the necessary nutrients, and sooty fungal infection violates leaf assimilation. Blackened dehydrated leaves dry over time. In the absence of treatment of this disease in plants or insufficient application of measures, the formation of fruits slows down.
