| Abstract:
The bermudagrass mite, Eriophyes cynodoniensis, is a reoccurring pest of bermudagrass, Cynodon spp., and it can cause a significant loss of stand when other biotic or abiotic stresses are present. Thirty-two commercial cultivars and 47 other bermudagrass varieties were assayed for their susceptibility to the bermudagrass mite under greenhouse culture. The cultivars, 'Cardinal', 'GN-1', 'Midlawn', 'Tifsport' and 'Tifway' expressed no symptoms (terminal rosetting) during the approximate 9-week test period and may exhibit levels of resistance to the mite. However, 'Tifway' has showed susceptibility in previous studies and therefore these cultivars may not all be resistant. Three of the varieties also exhibited zero terminals with symptoms. Most of the commercial cultivars including many of the newer ultradwarf bermudagrass cultivars are highly susceptible to the mite and had greater than 14 to 59 infested/rosetted terminals per 7.5 x 7.5 cm plant. | |
