Abstract/Contents: | "White grubs are perennial pests of both the cool- and warm season turfgrasses in North America. A 3-yr-old replicated planting of several varities of Texas bluegrass, Poa arachnifera Torr., and its hybrids with Kentucky bluegrass, P. pratensis L., was evaluated for resistance to white grub damage. A field population of Phyllophaga spp. (prob. P. congrua) had established and was causing significant damage across the replicated plots. On 31 May 1996, a visual rating of white grub damage to the grass in each turf plot was taken on a scale of 1-9 (turf damage, 9=most damage with loss of sand, yellowing and loss of root anchoring; 1= no damage or loss of turf quality). Plots were visually examined and the leaves of 4-5 random plants within the plot were pinched and pulled to indicate potential root damage and loss of anchoring. Based upon these results across a randomized planting in field plots exposed to natural adult selection, it appears that the two Texas bluegrass selections, Syn1 and Syn2, and the three Texas bluegrass x Kentucky bluegrass hybrids, 90-13-16, 90-13-8 and 90-16-1, have considerable resistance to white grub larvae. TXKY90-15-6 and TXKY-92-35-1 are very susceptible and sustained significant damage and loss of stand." |
