DISEASE MONOGRAPHS
Brown Rot
Monilinia fructicola
Brown rot is one of the most important and devastating diseases of stone fruit.
Early Blight
Alternaria Solani
Early Blight (Alternaria Solani), despite its name, usually causes infection and symptoms on mature plants and plant parts, often after fruit set.
Fusarium Wilt
Fusarium Oxysporum
Fusarium wilt is similar symptomatically to Verticillium wilt. Early signs include wilting in the heat of the day and yellowing of lower, older leaves.
Late Blight
Phytophthora infestans
Late blight is classified as a water mold, not a fungus, and appears on foliage as irregular brown or black spots on top of leaves and stems.
Rhizoctonia
Rhizoctonia Solani
Rhizoctonia (with Fusarium and Pythium) is a major cause of “damping off” seedling disease. Can cause stem and stolon canker in potatoes, pod rot in peanuts.
Verticillium Wilt
Verticillium albo-atrum Verticillium dahliae
Verticillium wilt is similar symptomatically to Fusarium wilt. Lower leaves develop irregular yellow blotches that eventually turn brown and die.
