Alternariosis

Alternaria sp. It is a genus of filamentous fungi that includes several plant pathogenic species. These fungi reproduce using asexual spores known as conidia, which are dispersed by wind, water, and direct contact. Alternaria can survive on infected plant debris and in soil for long periods. Under favorable conditions, spores germinate and penetrate plant tissues through wounds or stomata. The fungus produces toxins that kill plant cells, allowing the pathogen to feed on dead tissues. Alternaria is especially active in conditions of high humidity and moderate to warm temperatures, which facilitates its spread and the initiation of new infections. This pathogen has the ability to form spores rapidly, allowing it to multiply and cause epidemics in a short period of time.
