| Abstract/Contents: | "The objective of this project was to formulate short-term management recommendations for invasive ECF in golf courses of the Northeast U.S. This trial was conducted on golf course rough at Niagara Falls Country Club, Lewiston, Niagara County, NY using natural field infestations of ECF. An early application targeted larvae as late third and early fourth (ultimate) instars, and a late application targeted mid to late fourth instars. The experimental design was a RCB with six replicates for each application time. Experimental plots were 9 m2 (3 m Œ 3 m). Early applications were made 2 May 2007 and late applications 25 May 2007. Liquid and wettable formulations were applied using a backpack CO2 sprayer calibrated to deliver 2.6 liter of material per 1000 ft2 at 30 psi, through two flat-fan TeeJet 8002VS spray nozzles. An equivalent vol of water was similarly applied to untreated checks. Granular formulations were applied using a Scotts handheld broadcast spreader. No post-application irrigation was made. At the time of early application, weather conditions were partly cloudy with a slight breeze. Average grass ht was 7.6 cm. Air temp was 12.8°C, average soil temp was 10.6°C (1-inch) and 9.4°C (3-inches). Conditions at the time of late application were clear and sunny, moderately breezy. Average grass ht was 8.2 cm and the turf was visibly water-stressed. Air tempwas 23.9°C. Average soil temp was 13.9°C (1-inch) and 12.8°C (3-inch). Mean thatch depth for both applications was 1.1 cm. Grass was maintained at a mowing ht of 8.9 cm for the duration of the experiment. Rainfall during this project was negligible: 0.5 mm on 2 May and 0.25 mm on 28 May. Early applications were rated 7 May 2007 and late applications 30 May 2007 by removing six 10.2-cm diameter cores from each experimental plot. Larvae were extracted by placing samples into modified Tullgren funnels for a 24-h period. Due to the large quantity of material, samples were stored at 4.4°C until processing. All cores from a single block were extracted simultaneously to control for variation in extraction rates due to storage or soil moisture. Only five (early) and four (late) replicates were analyzed due to negligible populations in some of the untreated checks at the time of evaluation. To achieve normality, data were transformed using (square root[x+1]). ANOVA was used for statistical analysis, and Fisher's Protected LSD (Prob ≤ 0.05) for means separation. Results using untransformed means for early and late applications are presented in Tables 1 and 2, respectively. Sevin SL, widely used by the turf industry, was applied at the standard labeled rate for ECF larvae in New York State (8.17 lb (AI)/acre). There was significant control in both the early (77.8%) and late (75%) applications. Only two other early application treatments showed significant control: Aloft SC (0.36 lb clothianidin, 0.18 lb bifenthrin (AI)/acre, 83.4%) and the high rate of Meridian (0.27 lb (AI)/acre, 77.8%). Neither treatment, however, showed significant efficacy in the late application. Among late applications, only two treatments other than Sevin SL demonstrated significant control: the high rate of Duocide (0.2 lb bifenthrin, 8.0 lb carbaryl (AI)/acre, 87.5%) and the low rate of Meridian (0.2 lb (AI)/acre, 68.8%). The Duocide treatment contained an equivalent rate of carbaryl (8.0 lb (AI)/acre) as Sevin SL and did not show significantly higher control. Duocide was not tested in the early application. Arena 50 WDG, Bifenthrin 7.9EC, Conserve SC, Merit 2F and three rates of Provaunt showed no significant efficacy in either the early or late applications. The lack of post-application irrigation and subsequent dry conditions may have contributed to the poor results among those products." |
