What is plant leaf diseases?
On the other hand, pathogenic fungi cause plant diseases such as anthracnose, leaf spot, rust, wilt, blight, coils, scab, gall, canker, damping-off, root rot, mildew, and dieback. Systemic foliar pathogens are major causes for yield and commercial crop losses and diminished crop quality [2].

- Keep the plant away from other plants temporarily.
- Monitor daily to ensure the infection has stopped spreading.
What pathogen causes leaf spot?
Bacterial leaf spot diseases are most commonly caused by Pseudomonas spp. or Xanthomonas spp. Bacterial plant pathogens often live on plant surfaces in low numbers without causing immediate symptoms. They can travel long distances on moist air currents or be moved short distances on splashing rain and irrigation.
