TechNotes June 24 – Moisture Stress, Soil Temps

TechNotes are provided weekly by Syngenta Professional Products

MOISTURE STRESS. In many parts of the United States moisture stress is present on many homelawns. In areas where supplemental irrigation is needed and water conservation is critical, a few suggestions:

Water during times when evapotranspiration is the lowest. Watering during the middle of the day will result in significant evaporation of water not only from the turf but from sprinkler water spray prior to the water hitting the turf. Night watering has been reported to increase the severity of disease however compared to water loss the potential increase in disease severity is minimal.

Water deeply and infrequently. Warm season grasses have a deep root system allowing them to absorb deeper. Deep infrequent watering also allows for a greater hardening off of the turfgrass plant. In some instances where hand watering is being implemented this may be difficult.

Bluish colored turf is a sign of wilting. Water when the turf needs moisture the most, which is at the first sign of wilt.
