Phytophthora Blight
Devastating fungal disease caused by Phytophthora species (primarily P. capsici and P. infestans), famously responsible for the Irish Potato Famine in the 1840s. Affects all plant parts including roots, stems, leaves, and fruits in warm, wet conditions. The pathogen is technically an oomycete (water mold) that thrives in saturated soils and can survive in soil for 5+ years.

Immediately apply systemic fungicide (mefenoxam) as soil drench
Mosaic Virus
Mosaic virus is a group of plant viruses that cause mottled, patchy patterns on leaves and can affect a wide variety of plants. The virus creates characteristic yellow, white, and green mosaic patterns, often accompanied by stunted growth and deformed plant parts. This highly contagious disease spreads rapidly through insect vectors and contaminated tools.
