i have been having fungus problems this year as well. and early. usually dont show up until early july. it has been hot and humid here in s.e. ga. very early. research daconil. its not very heavy, and its not systemic. just was your fruit well. much less potent than what is on the store bought stuff. once you see signs of disease, i have found it impossible to stop it. i removed infected foliage when its dry, very carefully. then i spray ortho. definently slows it down. i have something on big beef plant that i have never seen. definently fungal, because daconil and leaf removal is slowing it down. grown big beef for three years and always the first to get disese. produces loads of fruit, maybe thats why.

Hi, Did you get it IDed? Your photos are gone. Remy

Botrytis, a fungal disease caused during some parts of the year in wet weather. If this is on the blooms now, there is nothing to do. Many of us don’t do anything, it occurs, we live with it. You may remove the damaged petals if you wish.
