Causes of Gray Tomato Plants

There are several different factors that can cause tomato plants to turn gray. Let's take a look:

Bacterial Diseases: Bacterial diseases can also cause tomato plants to turn gray. Bacteria can infect the leaves, stems, and fruit of tomato plants, leading to their decline. Bacterial diseases like bacterial canker and bacterial speck can cause your tomato plants to turn gray.

Insects: Certain insects like aphids, spider mites, and whiteflies can cause tomato plants to turn gray. These insects feed on the sap of the plants, causing them to wither and turn gray. Insect infestations can be controlled with insecticides.
