[1] Botryotinia polyblastis generally attacks its host in three stages beginning with the flower and ending with an infection of the leaves.

[2] The disease then causes the formation of elliptical-shaped, tan leaf spots appear on the tips of the hosts leaves.

[2] Like many ascomycetes, the sclerotia of Botryotinia polyblastis germinate in the spring, once weather conditions are favorable to form an ascocarp.

[4] Botryotinia polyblastis forms an apothecium, a wide, open, saucer shaped fruiting body as its ascocarp.

[3] There are two main types of control that can be practice to avoid infections by Botryotinia polyblastis; cultural or chemical.

In order to prevent an epidemic, basic sanitation can be practiced by removing all dead tissue from fields before planting for the next season.

[6] It is also possible to remove all the flowers from the fields before apothecial production and avoid having to deal with prevention or treatment of a fungal disease such as Botryotinia polyblastis.
