ABSTRACT

One fungal isolate CM2 parasitic to Sclerotinia sclerotiorum and S. minor causing Sclerotinia rot of lettuce was identified as Paraconiothyrium minitans based on its morphological and molecular characteristics. P. minitans CM2 grew best on PDA with pH 6.5 at 22 oC under alternating cycles of 12 hr near ultraviolet light and 12 hr darkness. Scleroria of S. sclerotiorum and S. minor treated with conidial suspension of P. minitans CM2 did not directly germinate and produced no apothecia.
