Crop rotations involving corn, soybean, and peanut were established in microplots and field plots to determine their effect on Cylindrocladium black rot (CBR) development in peanut. Corn in a nonhost to the pathogen Cylindrocladium crotalariae. Soybean in a host, but may reduce inoculum efficiency of microsclerotia. In the field, cultivar Ransom soybean or Pioneer corn hybrid 3389 planted in alternate years reduced the rate of CBR increase in a partially resistant peanut cultivar, NC 8C
