Little is known about the interactions of grape Infection process and host responses to Elsinoë ampelina , the causal organism of grapevine anthracnose | SpringerLink Anthracnose Colletotrichum gloeosporioides Glomerella cingulata [teleomorph] Colletotrichum acutatum. ABSTRACT The causal organism responsible for the recent outbreak of almond and peach anthracnose in California was identified and characterized as Colletotrichum acutatum. In the spring, sclerotia on infected shoots germinate to produce abundant spores (conidia) when they are wet for 24 hours or more and the temperature is above 36 degrees F. Conidia are spread by splashing rain to new growing tissues and are not carried by wind alone. Anthracnose caused by, Roy A, Bordoloi DK, Paul SR (1998) Reaction of chili (.

In 1905 Sheldon {20) reported an undetermined anthracnose fungus found on red clover in West Virginia; the following year he identified G. trifolii {21). There are no resistant varieties.

Since the species of the causal organism is different from the anthracnose pathogen of corn, orchardgrass and ryegrass, it is pathogenic only to sorghum. The lesions are at first yellow swelling and then become oval ones of 1-2mm in length and 0.5mm in width. Causal organism - Colletotrichum capsici.
