| Abstract/Contents: | "Merit 75W and Tempo 20W were compared as side by side treatments on whole greens with 1/2 half of a green being a replicate of each treatment. Treatments were applied 23 May, replicated 4 times; there was no untreated control. Compounds were applied with a Cushman Turfmaster 125 sprayer and watered in with the same sprayer at 120 gal/acre. Water pH was 8.33. Environmental conditions at start (8:35am) and finish (11:30am) of treatment applications were, respectively: air temperature, 23.5°C and 32.5°C; RH, 43% and 54%; sky clear; soil temperature (surface), 25.5°C and 33.5°C, (1 inch) 25.5°C and 29°C; soil very moist. Efficacy was evaluated on 31 Jul (69 DAT) by treating entire greens with Tempo 2 at the rate of 0.04 lb (AI)/acre, syringing the green 8-10 min and counting the no. of cutworms flushed to the surface in a sample area of 4 m². Two areas were sampled on each treated half of each green. Within these sample areas, the no. of obvious cutworm feeding holes were also counted. The time of evaluations (and appropriate treatment time) for these trials was left to the discretion of the course superintendent. Other greens on the course were treated on 22 Jun or 39 days prior to the time a decision was made that the Merit/Tempo trial greens needed to be treated. In other words, this preventative application trial extended the time of a "normal" curative treatment by about 5 1/2 weeks. No phytotoxicity was observed." |
