Today we completed soil fumigation process on Dye's Valley greens. Below is a video of the process.
Plant parasitic nematodes are transparent worms inhabiting the soil that are not visible to the naked eye. These parasites feed on living roots of turfgrass, inhibiting growth and development of the turf. Nematode assays are used to determine the number and type of nematodes per volume of soil, and can be usedful in identifying if nematodes are a limiting factor for growth of the turfgrass. In the case of Dye's Valley, nematode populations have been increasing steadily in recent years, now to the point where they are problematic for the putting green surfaces. Curfew is a soil fumigant applied as a liquid which quickly volitalizes as a gas, moving throughout the soil profile. Curfew kills nematodes and other soil inhabiting insects on contact. This product has been used effectively for over 30 years. Nematodes controlled with Curfew include: Awl, Cyst, Lance, Ring, Root-knot, Spiral, Sting, Stubby-root. Slits in the greens are expected to be healed in within 7 to 14 days after application.
