Fungal Disease

olletotrichum capsici is an air-borne, seed-borne, and also soil-borne pathogen. It can survive in moist soil and plant debris for several years. The fungus can spread by rain splash and irrigation water. It can also spread by infected soil, farm tools, and shoes. The fungus can be carried by chilli seeds intraembryonally. Enzymes produced by C. capsici can disrupt seed tissues.

The relationships among rainfall intensity, duration and crop geometry and the dispersal of inoculum possibly lead to different levels of disease severity (Dodd et al., 1992). The effects of temperature often interact with other factors, such as leaf surface wetness, humidity, light or competitive microbiota (Royle and Butler, 1986). The duration of the surface wetness, however, appears to have the most direct influence on the germination, infection and growth of the pathogen on the host. Generally infection occurs during warm, wet weather. Temperatures around 27 °C and high humidity (a mean of 80%) are optimum for anthracnose disease development (Roberts et al., 2001).
