White mold on cole crops

Feb 18, 2011 7:10 AM

Crops: Brussels sprouts, cauliflower, cabbage, collards, lettuce

Fungal causal agent: Sclerotinia spp.

Symptoms: White mold growth, black sclerotia (survival structures of the fungus)

There has been a major attack of white mold on cabbage, caused by Sclerotinia sclerotiorum in commercial production in Florida in the last two months. White mold has never been a major issue on cole crops in FL till recently, and the increasing cold weather accompanied by wet conditions are the mostly likely reason. The disease has also caused some issues on cauliflower, collards, and broccoli at the UF research station trials at NFREC, Quincy.
