Abstract

Creeping bentgrass (Agrostis stolonifera) used on golf course putting greens are some of the most intensively managed areas of turf and are subjected to high stress. Heat stress results in lowered photosynthetic efficiency and inadequate sugar production. An exogenous application of fructose could compensate for the lack of sugar being produced. The objectives of this research were to determine the effect of exogenous applications of fructose on heat stressed creeping bentgrass. Field results showed some phytotoxicity with high rates of fructose, while lower rates showed no visible damage compared to an untreated control. Low rates of surfactant resulted in little phytotoxicity, while high surfactant rates showed damage. Fructose had no positive effect on turf quality. A surfactant study was then designed to measure the effect of various surfactants on fructose uptake. This study revealed that as hydrophilic to lipophilic balance increased, absorption of fructose increased.
