Early blight is a disease caused by a fungus which survives in the soil as spores from year to year. PACKINGHOUSE SANITATION: The potential for development of fruit decay after harvest is least if the plants are dry and free of decay at the time of harvest. Late blight, which is caused by the pathogen Phytophthora infestans, is one of the most destructive and contagious plant diseases. Verticillium wilt. curly top) that cause "twisted" growth especially of the newer, younger leaves. Cool, damp soil, overwatering, and overcrowding all increase probability of infection.

Fruit Anthracnose - Colletotrichum spp. It affects leaves, fruits and stems and can be severely yield limiting when susceptible cultivars are used and weather is favorable. However, these practices are ineffective in regions where hot and humid weather favor spread of the pathogen and development of the disease. Use the same controls as for septoria leaf spot. 6. Currently, numbers of microbes have been used as soil or plant inoculants in different plants including tomato as biocontrol. The research was conducted through the Tomato Organic Management and Improvement Project (TOMI), led by Hoagland, with a goal of improving organic tomato production and disease resistance.
