| Abstract/Contents: | "Velvet bentgrass is significantly more resistant to dollar spot than is creeping bentgrass. However, this resistance does not permit turf managers to reduce fungicide use because velvet bentgrass is extremely susceptible to copper spot. Varieties with resistance to both diseases are needed in order to manage velvet bentgrass with fewer fungicides. We screened the 250 accessions of the New England Velvet Bentgrass Collection for copper spot resistance to determine if resistance was present. Sixty percent of the accessions tested were significantly more resistant than the standard varieties 'SR7200' and 'Greenwich' suggesting that development of resistant varieties should be possible. Copper spot, caused by the fungus Gleocercospora sorghi, is a major disease on velvet bentgrass that limits the grass utility in hot summer regions. Current varieties are susceptible, but resistance is common among accessions collected from old golf courses in New England. Some accessions are resistant to both copper spot and dollar spot." |
