Abstract/Contents: | "Thirteen treatments were applied 28 aug on a golf course fairway in Ossipee, NH. Treatments were applied early morning and immediately watered in after application with 0.3 in. water. Plot size was 10 X 10 ft repeated 4 times in a randomized complete block design. Liquid and powder formulations were applied with a watering can at a spray volume of 5 gal/1,000 ft2. Granules were applied using a homemade salt shaker. Sample size consisted of five, 4.25 in. cup cutter plugs from each plot. Live grubs were recorded and converted to a ft2 count. Plots were rated on 5 Oct 38 DAT. Conditions at the time of treatment were: air temperature, 70oF; soil temperatures at 1 inch, 76oF, soil temperature at 3 inch 2oF; thatch depth (natural), 0.25 inch; soil pH, 5.2; thatch pH, 5.2; thatch pH, 5.6; slope, 0%; soil texture (loam), sand 53%, silt 37%; clay 10%; soil organic matter, 9.1%; soil moisture, 23.6%; post treatment precepitation, 4.8 inch rain. Pretreatment grub counts averaged 40 grubs/ft2. All the chemical treatments performed well with no difference between the low and high rates. The nematode treatments give little control. No phytyotoxicity observed. |
