MANAGEMENT PRACTICES AND SCLEROTINIA ON CANOLA, DRY PEA, CHICKPEA, LENTIL, AND SUNFLOWER, 2002. p. 22. Proceedings of the International Sclerotinia Workshop. 2003. Technical Abstract: A multi-disciplinary team of scientists is conducting research to develop guidelines for long-term diversified crop production systems and to provide producers with management flexibility for developing their own cropping systems. The effects of management practices, crop sequence and biological control, on Sclerotinia sclerotiorum disease were evaluated in 2002. 1) A uniform sunflower crop was seeded in 2002 following ten crops (grown in 2000) to evaluate the carryover of Sclerotinia disease. The number of sunflower plants infected with Sclerotinia basal stalk rot was related to the previous crops with the highest level of Sclerotinia basal stalk rot following crambe. 2) Probably, because of the dry conditions during the 2002 growing season, no Sclerotinia was detected on buckwheat, chickpea, canola, dry pea, or lentil. 3) The efficiency of Coniothyrium minitans (Intercept WG®) in reducing the risk to Sclerotinia disease was evaluated. Sclerotinia basal stalk rot on sunflower tended to be less with the C. minitans treatment compared to no treatment, and with the no-till treatment compared to the other tillage treatments.
