Tomato Leaf Mold
Tomato leaf mold is a common fungus that attacks tomatoes grown in humid places. The mold attaches itself to the leaf and feeds off of the humidity to grow and thrive.
It is vital to take care of the situation immediately so that the foliage isn’t dramatically infected. Infected leaves will decrease the amount of tomatoes yielded.
Luckily, this fungus is pretty simple to treat and cure.
Causes and Symptoms
With this type of fungus, it is rare that the fruit is infected as well. The signs to look for are all on the leaves. The tops will begin to develop small, white, gray, yellow, or pale green patches. The underside of the leave will have a fuzzy feel that is purple in color. Sometimes the fuzz will be olive green. The “fuzz” is actually spores of the fungus.
The infected tissue becomes yellowish-brown and the leaf begins to wither, eventually falling off of the plant. Untimately the whole plant will wither and die.
In the rare case that the blossom or fruit is infected, the mold will appear as a black sore-like lesion. The black can grow to cover over half of the surface area of the plant or blossom. Tomato leaf mold affects ripe tomatoes as well as green tomatoes.
