Plants planted with rows in an east–west direction have more severe disease than do plants planted north–south. This implies that if one plants tomato plants in a north–south manner they will be less susceptible. It is also suggested to highly monitor plants in April through June [clarification needed]. This is when the pathogen is most ...

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]

Alternaria is a genus of Deuteromycetes fungi. All species are known as major plant pathogens.They are also common allergens in humans, growing indoors and causing hay fever or hypersensitivity reactions that sometimes lead to asthma.
Fusarium wilt is a common vascular wilt fungal disease, exhibiting symptoms similar to Verticillium wilt. This disease has been investigated extensively since the early years of this century. The pathogen that causes Fusarium wilt is Fusarium oxysporum (F. oxysporum). [1] The species is further divided into formae speciales based on host plant.
In 2015 greenhouse tomato crops in Jordan showed mild foliar symptoms during the season, with fruit then developing strong brown rugose symptoms. Total RNA was extracted from the plants and Reverse transcription polymerase chain reaction (RT-PCR) were negative for many common tomato viruses but indicated the presence of a new tobamovirus. [1]
The primary host for TYLCV is the tomato plant, and other plant hosts where TYLCV infection has been found include eggplants, potatoes, tobacco, beans, and peppers. [1] Due to the rapid spread of TYLCV in the last few decades, there is an increased focus in research trying to understand and control this damaging pathogen.
