Both strategies employ the same fungicide rotation:ġ. These tank-mixtures are most effective when applied to the foliage in 2 gallons of water per 1,000 square feet.įungicides may be used on either a curative or preventative basis for Pythium root dysfunction control. Tank-mixtures of Signature + Banol (4 + 2 oz/1,000 square feet) or Signature + Subdue Maxx (4 + 1 oz/1,000 square feet) also have provided good disease suppression. The same result may also be obtained by making the applications in larger volumes of water (4 to 6 gallons per 1,000 square feet) to drive the fungicide deeper into the canopy. Applications watered in with 1⁄ 8 inch of irrigation immediately have been slightly more effective than standard foliar applications. The most effective fungicides have been those belonging to the QoI (azoxystrobin, fluoxastrobin and pyraclostrobin) and QiI (cyazofamid) chemical classes. Standard Pythium fungicides, such as mefeanoxam (Subdue Maxx), propamocarb (Banol), and fosetyl-Al (Signature) have provided poor to moderate control of Pythium root dysfunction when applied alone. Biweekly solid-tine aeration during summer will increase root survival by creating temporary channels for air and water movement through the soil profile. of topdressing should be applied per 1,000 square feet each year. In general, 15% to 20% of the putting green surface area should be impacted by hollow-tine aerification annually, and 5,000 lbs. Frequent cultivation and topdressing are needed to maximize oxygen levels in the soil. Soil surfactants increase the uniformity of soil moisture across putting greens and will assist with water management. Avoid severe drought stress by irrigating before symptoms of wilt become widespread, and supplement with syringing and hand-watering of areas that dry out more quickly. during summer to increase photosynthesis and alleviate stress. Use regular soil and tissue testing to ensure that all other nutrients are present in adequate amounts. After establishment, creeping bentgrass should be fertilized with 4 to 6 lbs. Estoy de Acuerdo / I agreeĬreeping bentgrass greens should be constructed with at least 15% organic matter by volume to provide adequate water and nutrient holding capacity.
