T O M AT O E S Disease Cycle Powdery mildew probably overwinters on weed hosts. Conidia, the primary source of infection, are wind-borne and serve as both primary and secondary inoculum. Powdery mildew is a polycyclic disease. Conditions for Development Conidia can germinate in a wide range of temperatures, from 50º to 95º F. Infection is favored by temperatures under 86º F and high relative humidity. Once infection is established in a tomato leaf, temperatures above 86º F can speed up symptom development and death of leaf tissue. P O W D E R Y M I L D E W 51
S E P T O R I A L E A F S P O T 52 Septoria Leaf Spot – Septoria lycopersici Symptoms The first symptoms are usually visible on lower leaves after the first fruit sets and may also appear on stems, petioles and the calyx. Disease spreads upward, from oldest to youngest growth. Fruit infection is rare. The centers of leaf lesions are usually dotted with black pycnidia and often have a narrow yellow halo. Lesions can enlarge to 5 mm in diameter. Numerous leaf lesions can cause infected leaves to turn chlorotic, then brown and wither. T O M AT O E S
