Relationship of environmental factors to development of Sclerotinia minor and Sclerotinia blight of peanut
Sclerotinia minor Jagger myceliogenic sclerotial germination, growth, infection, and colonization of peanut (Arachis hypogaea L.) tissue was optimum at 20-25 C. Ninety-five to 100% relative humidity (RH) for more than 12 hours was necessary for germination. There was no difference in infection and …

Sensitivity and resistance of Sclerotinia minor to fungicides for control of Sclerotinia blight of peanut
Sclerotinia blight, caused by <i>Sclerotinia minor</i>, is a severe disease of peanut in Virginia. Vinclozolin (V), iprodione (I), dicloran (D), and pentachloronitrobenzene (PCNB) were evaluated for their fungitoxicity to <i>S. minor</i>. The mean ED₅₈ values for five isolates were found to be …

Evaluation of fungicide resistance in Sclerotinia minor and strategies for chemical control of sclerotinia blight of peanut
… possessing high levels of fungitoxicity to Sclerotinia minor, the causal agent of Sclerotinia blight of peanut. The two fungicides, ASC-66825 and RH-3486, are thought to have a different chemistry than the dicarboximide fungicides. The ED₅₀ value (dose required for 50% inhibition of mycelial …

The Role of Host, Environment, and Fungicide Use Patterns in Algorithms for Improving Control of Sclerotinia Blight of Peanut
… and improving fungicide timing for control of Sclerotinia blight of peanut, caused by Sclerotinia minor. A 5-day index (FDI) of disease risk was calculated daily by multiplying indices of moisture, soil temperature, vine growth and canopy density and summing the values for the previous 5 days. …

Characterization of Transgenic Peanuts Expressing Oxalate Oxidase for Governmental Approval of Their Release for Control of Sclerotinia Blight
<i>Sclerotinia minor</i> Jagger is a fungal pathogen of cultivated peanut (<i>Arachis hypogaea</i> L.) that can cause crop losses in excess of 50%. Fungicides are not completely effective at controlling the disease and can cost up to $311 per hectare for three applications. The ability to produce …
