| Abstract/Contents: | "In turfgrasses, disease management often entails multiple costs. In some instances, fungicide carrier volume can be adjusted to cover larger areas, thereby cutting fuel and time costs. Previous research has shown that carrier volume impacts fungicide efficacy, but newer products have not been tested. In 2015, a trial was developed to evaluate the impact of carrier volume on curative dollar spot (Sclerotinia homoeocarpa F.T. Bennett) applications of fungicides on a creeping bentgrass (Agrostis stolonifera cv. "007") putting green. Dollar spot developed naturally on 16 May. Fungicides [fluazinam (FZM), fluopyram (FPM), fluxapyroxad + pyraclostrobin (FLX+PYR), chlorothalonil (CHL), and propiconazole (PRO)] were applied at 815 L ha-1 and 408 L ha-1 using a CO2 powered backpack sprayer with TeeJet AI9508E (815 L) or TeeJet AI9504E (408 L). Treatments were applied from 25 June to 4 August. Turf was evaluated for infection every 7-14 d. While fungicides reduced dollar spot, CHL and FPM provided the most rapid reduction in disease. Following the second treatment, FPM, FLX+PYR, and PRO applied in a 815 L ha-1 carrier volume provided more control than 408 L ha-1. In contrast FZM provided better control in 408 L ha-1 during the same time period. After suspending treatments, FPM and FLX+PYR provided the longest residual control of dollar spot. Turf color and quality were both improved in fungicide treated plots when compared to the control, irrespective of spray volume." |
