Variation in oxalic acid production and mycelial compatibility within field populations of Sclerotinia sclerotiorum
This study was aimed at detecting mycelial compatibility groups and variations in oxalic acid production in Sclerotinia sclerotiorum. For this purpose, 121 isolates of this plant pathogen recovered from lettuce, soybean and sunflower field crops, and grouped in 46 MCGs were tested for their ability...
