Evaluation of Fungicide Control of Sclerotinia Stem Rot on Canola (SSR) Yin Chen Description of disease affecting crop Sclerotinia stem rot (SSR) is caused by fungus named sclerotinia sclerotiorum (Lib.) de Bary. It is a common disease in oilseed rape (Brassica napus) field. In Sweden, S. sclerotiorum can cause 60% yield reduction in infected fields (Nordin, 1992). SSR is a major disease of canola in North Dakota. The incidence ranged from 7-19% in North Dakota from 1991 to 1993. ( Lamey, 1995).
Fruits have abundant vitamins, minerals and carbohydrates as well as they constitute high amounts of water making them more susceptible for microbial spoilage. The average water content in fruits is 84.9%, carbohydrates 13.2%, protein 0.88%, fat 0.53%, and ash 0.46%. Along with vitamins and other organic compounds, fruits are excellent material for microbial growth. Because the pH level of fruits is relatively low and more acidic, yeast and mold have more competitive edge than bacteria. Citrus fruit
