Abstract/Contents:States that "the 'dew' [found] on turfgrass areas is not water of condensation. This water is the plant sap being pumped out of 'exudated' from the hydathodes. The hydathodes are relief mechanisms that transport excess water out of the plant system. Mentions a study that observed "exudated water increased infection and disease." It induced acceleration and increase in spore germination. Explains that "exudated water contains glutamine, a form of sugar that is ideal for bacterial and fungal growth"... The salt index of exudated water will rise sharply when quickly available plant foods, (especially nitrogen) are applied. If these salts are allowed to accumulate in the thatch or compacted soils surface root, stem, or lower leaf, burn may occur. The potency of the exudate can be demonstrated by gathering a cupful from a well fertilized green and pouring it in one spot. A chemical burn will result." Offers suggestions that may help prevent turf damage caused by exudated water." The majority of what is referred to as "dew" on the turfgrass plant is primarily guttation water (leaf exudates) that contain a high percentage of fertilizer salts which cause plant burn and increased disease. Careful spraying, especially in the early morning, could cut down on disease and fungicide.
