PRO TIP : Soil pH above 6.5 can enhance summer patch symptoms. Use acidifying nitrogen sources like ammonium sulfate to reduce high pH soils. Also, applying manganese sulfate at 6 lbs/A as a soil spray can also reduce summer patch symptoms.
Pythium Root Rot Organisms causing Pythium root rot on cool-season greens become active earlier than previously thought, when average 2” soil temperatures reach 60ºF for three consecutive days. For warm-season putting greens, initiate applications in late-summer or early fall when soil temperatures drop below 80°F for three consecutive days. These applications should be watered-in with 0.125” of irrigation.
