Abstract/Contents:"Water management is one of the most pressing issues turfgrass managers face in the arid regions of the world and periodically in temperate regions. In response to reduced water supplies, governments have enacted policies that restrict potable water use for non-essential uses. These reduced water conditions will limit the environmental benefits turfgrass provides like soil erosion reduction, ambient temperature reduction, and providing low cost playing surfaces. To reduce the appearance of drought stressed turfgrass, turfgrass managers will need to further modify primary cultural management practices for short- and long-term drought periods to maintain healthy and playable turfgrass stands. Herbicides are the primary management practice to reduce difficult to control weeds in turfgrass stands. However, under reduced water statuses, herbicide efficacy can be reduced as the plant is not able to perform normal physiological functions. The objectives of this research are to 1) determine the severity of herbicide turfgrass phytotoxicity at differing water statuses and 2) if these differing turfgrass water statuses effect herbicide efficacy. These objectives will be met by performing field and greenhouse experiments judging turfgrass quality after herbicide treatments applied following a period of gradient irrigation. Differing water statuses will be created in the field experiment by using a Linear Gradient Irrigation System (LGIS), and in the greenhouse experiment pots will be exposed to four decreasing evapotranspiration (ET) levels. Both experiments are currently underway at time of abstract submission, and findings from two trials of each experiment will be available and presented at CSSA conference. This research will develop a decision-making tool for turfgrass managers to determine the minimum water status needed for effective herbicide use in turfgrass species. Knowing the minimum water status can prevent superintendents from spraying herbicides that will not effectively control desired weeds or cause non-target phytotoxicity to turfgrass stands under drought conditions."
