| Abstract/Contents: | "Clove oil and medium-chain fatty acids (MCFAs) are compounds known to have nonselective herbicidal activity. Hexanoic and octanoic acid are both MCFAs. These compounds are naturally occurring and breakdown quickly in the environment, making them environmentally safe. These compounds have potential to compete with synthetic herbicides as alternative weed control agents, but they are limited in use to non-selective weed control. Little research utilizing clove oil and MCFAs has been conducted in turfgrass. Since these compounds function as nonselective herbicides, research was conducted to evaluate weed control efficacy in a dormant turfgrass setting using bermudagrass ('Tifway' Cynodon transvaalensis x C. dactylon). Research was conducted at the Auburn University Turfgrass Research Unit in Auburn, AL. A randomized complete block design with three replications and plot sizes of 4.7 m2 were utilized. Bermudagrass turf was not mown, irrigated, or fertilized as this is normal management for dormant turfgrass. Treatments included clove oil at 10 and 30 L ha-1, hexanoic acid at 16.8 L ha-1, octanoic acid at 16.8 L ha-1, hexanoic acid at 16.8 L ha-1, clove oil at 10 L ha-1, octanoic acid at 16.8 L ha-1, + clove oil at 10 L ha-1, Scythe (Dow AgroSciences LLC, Indianapolis, IN) at 3.2 kg ai ha-1, and Trimec Classic (PBI Gordon Crop., Kansas City, MO) at 4.0 L ha-1. A non-treated check was also included. Treatments were applied in a 280 L ha-1 1 spray volume. Weed species evaluated included henbit (Lamium amplexicaule), common chickweed (Stellaria media), and annual bluegrass (Poa annua). Visual percent control ratings were taken at 8 and 15 days after application (DAA) where 0 = no plant injury and 100 = complete plant death. For discussion purposes, weed control greater than 70% was considered acceptable weed control. Data were subjected to ANOVA and means were separated using LSD at an alpha level of 0.05. Clove oil (30 L ha-1) and octanoic acid were the only non-combination treatments to control some weeds acceptably. However, clove oil (10 L ha-1) in combination with octanoic acid improved control. This treatment resulted in satisfactory weed control that was equal to or better than the standard, Trimec Classic. Clove oil + octanoic acid resulted in greater than 80% weed control for all species evaluated, at 8 DAA. Weed control from clove oil + ocatanoic acid was slightly less 15 DAA but was still considered acceptable. Octanoic acid 15 DAA was the only treatment that resulted in some selectivity between weed species evaluated; Henbit was more sensitive than annual bluegrass. Annual bluegrass was the most tolerant of the treatments overall; this fact may indicate that grasses are less sensitive to clove oil and MCFAs. Hexanoic acid, Scythe, or clove oil (10 L ha-1) applied alone and the combination of hexanoic acid + clove oil resulted in unsatisfactory weed control at all rating dates. No bermudagrass injury was observed from any treatment and no green-up delays were observed in the spring." |
