Septoria lycopersici infects the tomato leaves via the stomata and also by direct penetration of epidermal cells. [3] Symptoms generally include circular or angular lesions most commonly found on the older, lower leaves of the plant. [1] The lesions are generally 2–5 mm in diameter and have a greyish center with brown margins.
[1] [2] Wilt, stunting and lack of vigor can be observed as the primary symptoms, and infected leaves can possibly show interveinal chlorosis that leads to premature defoliation. [ 3 ] [ 4 ] The distinctive characteristic of P. lycopersici is that it causes brown lesions on the surface of medium roots which are known as a brown root rot. [ 4 ]

Independently of each other, salicylic acid, ethylene, and jasmonic acid can influence the susceptibility of tomato to AAL. Diagnosis of AAL is often from observing signs and symptoms from this fungal pathogen. In addition, a tomato cultivar's resistance to a toxin produced by AAL also affects disease development.

The problem will progress up the plants until they’re virtually bare. General-purpose garden fungicides will control this late-spring disease that is made worse by water on leaves. Spider mites.
On the flip side, homemade sauces usually have less sodium than store-bought, which can help alleviate heartburn. Eating tomatoes might help you consume more nutrient-dense meals.
Alternaria solani is a fungal pathogen that produces a disease in tomato and potato plants called early blight. The pathogen produces distinctive "bullseye" patterned leaf spots and can also cause stem lesions and fruit rot on tomato and tuber blight on potato. Despite the name "early", foliar symptoms usually occur on older leaves. [3]
