Fusarium oxysporum f.sp. lycopersici is a fungal plant pathogen.It is a big pathogen to the tomato plant. It has a violet to white color on most media but does not produce a pigment on King's B medium.
Like its relative Phytophtora cambivora, it can cause ink disease of chestnuts (Castanea sativa). [5] The species is a cause of foot rot in tomatoes, causing discoloration and lesion in the stem. Progression of lesions leads to girdling, root system rot and plant collapse. Foliage will not be affected until plant stem has become girdled. [2]

Cladosporium fulvum is an Ascomycete called Passalora fulva, a non-obligate pathogen that causes the disease on tomatoes known as the tomato leaf mold. [1] P. fulva only attacks tomato plants, especially the foliage, and it is a common disease in greenhouses, but can also occur in the field. [2] The pathogen is likely to grow in humid and cool ...
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]
Spores spread to healthy tomato leaves by windblown water, splashing rain, irrigation, mechanical transmission, and through the activities of insects such as beetles, tomato worms, and aphids. [1] Provided the environment is conducive for disease development, lesions usually develop within 5 days of infection.
Xanthomonas campestris pv.vesicatoria is a bacterium that causes bacterial leaf spot (BLS) on peppers and tomatoes. It is a gram-negative and rod-shaped. [1] It causes symptoms throughout the above-ground portion of the plant including leaf spots, fruit spots and stem cankers.
