Elsinoë ampelina is a plant pathogen, which is the causal agent of anthracnose on grape. [1] This type of anthracnose affects several plant varieties, including some brambles and wine grapes. Grape anthracnose can be identified by the "bird's eye" lesions on the berries and sunken black or greyish lesions on leaves and shoots.

Lawrence Ogilvie (5 July 1898 – 16 April 1980) was a Scottish plant pathologist who pioneered the study of wheat, fruit and vegetable diseases in the 20th century.. From 1923, in his first job and aged only 25, when agriculture was Bermuda's major industry, Ogilvie identified the virus that had devastated the islands' high-value lily bulb crops in 204 bulb fields for 30 years.
The disease starts out as yellowing and drooping on one side of the plant. Leaf wilting, plant stunting, browning of the vascular system, leaf death and lack of fruit production also occur. [8] F. oxysporum f. sp. melonis attacks muskmelon and cantaloupe. It causes damping-off in seedlings and causes chlorosis, stunting and wilting in old plants.
