| Abstract/Contents: | "The objective of this project was to evaluate the efficacy of products labeled in New York State against first and second instars of ECF in home lawns. The experiment was conducted in Pittsford (a Rochester suburb), Monroe County, NY, on well-maintained home lawns, where dense populations of adults were observed. Natural infestations of larvae at four separate residences were targeted, using a RCB design with eight replicates. Experimental plots were 9 m2 (3 m Œ 3 m). The same treatments were evaluated on two application dates, 17 Sept 2007 for the early application and 15 Oct 2007 for the late application. All treatments were applied at labeled rates, or at both the lowest and highest allowable rates if a range was specified. Liquid and wettable formulations were diluted in 0.5 liter of water and applied using a 1.5-gal Tractor Supply pump sprayer. Granular products were evenly distributed using a shaker jar. Normal lawn irrigation practices were maintained after both application timings, and actual amt varied widely across sites. At the time of early application, skies were clear, wind negligible, and air tempincreased from 15 to 26°C. Average soil temp across all sites were 17.5°C (1-inch) and 17.2°C (3-inch). At the time of late application, skies were clear with a slight breeze, and air temp increased from 10.0 to 23.9°C. Average soil temp across all sites were 16.9°C (1-inch) and 16.7°C (3-inch). For both applications and across all sites, mean thatch depth was 17 mm and mowing ht 10.2 cm. All experimental plots were rated on 1 Nov 2007 by removing 10 6-cm diameter cores from each. Larvae were extracted by placing all samples from a single plot together in a modified Tullgren funnel for a 24-h period. Only five replicates were used for statistical analysis due to negligible populations in three of the untreated checks at the time of evaluation. To achieve normality, data were transformed using log(x+0.5). ANOVA was used for statistical analysis, and Fisher's Protected LSD (P d 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 in the turf industry, did not show significant control as either an early (50%) or late (30%) preventive treatment. Among early applications, five treatments significantly suppressed larvae. Duocide gave 100% control. For both Allectus and Merit 2F, there was evidence of an inverse rate response. While both rates of Allectus gave significant control, efficacy fell from 100 to 75% at the low and high rates, respectively. For Merit 2F, efficacy fell from 95 to 60% at the low and high rates, respectively. The high rate of Provaunt gave 95% control and Prosect 0.15G 90%. Among late applications, four products at varying rates exhibited significant control. These included both rates of Allectus G (95- 100%), Prosect 0.15G (95%), both rates of Provaunt (90-95%), Duocide (90%), and both rates of Merit 2F (85- 90%). No significant suppression was detected for any of the biologically-based alternatives at either application time, Nemasys (35- 55%), Ornazin (35-40%) and Scanmask (50-60%)." |
