| Abstract/Contents: | "Tests were conducted on 2 X 2 ft plots at the Purdue University Agronomy Research Center in West Lafayette, IN. The plots were arranged in a RCB design, replicated 5 times. A PVC cylinder (6 inch inside diameter) was buried 4 inches into the soil and projected 1 inch above the soil in the center of each plot. Five 3rd instar JB grubs were infested within each cylinder on 1 Oct. Merit 0.5G was used as the insecticide standard treatment and was applied with a homemade salt shaker on 3 Jul. Orthene and Tame treatments were applied on 4 Oct. Dispersible formulations were applied through a TeeJet® 11003 spray tip attached to a 60-ml plastic syringe at a volume of 2 gal/water ft₂. All plots received 0.5 inch of irrigation immediately after treatment. There were two untreated plots in each replicate. Thatch depth (natural) was 0.13 - 0.25 inches on a silt loam. Efficacy was evaluated 25 Oct by extracting the cylinders, separating the soil and grass, and recording the number of live grubs. Orthene TTP 75SP alone and in combination with Tame 2.4EC were the only treatments that significantly reduced the JB grub population density relative to Tame 2.4EC as well as untreated check. Merit was only slightly effective, possibly because of the JB grubs being in late instar." |
