Cutless* Back
Application Guidelines
Bentgrass Fairways
Apply Cutless 50W to fairway height bentgrass at a rate of 0.5 to 0.75 lb/acre in the early spring following resumption of active growth. Repeat applications of 0.25 to 0.5 lb/acre of Cutless 50W should be made at 3 to 6 week intervals until late summer or early fall.

Kentucky Bluegrass and Perennial Ryegrass
Apply Cutless 50W to Kentucky bluegrass and perennial ryegrass at a rate of 0.75 lb/acre in the early spring following resumption of active growth. Repeat applications of 0.5 to 0.75 lb/acre of Cutless 50W should be made at 3 to 6 week intervals until late summer or early fall. Cutless can be used on over-seeded perennial ryegrass.

Tifway Bermudagrass (419) Apply Cutless 50W to Tifway bermudagrass at a rate of 0.5 to 0.75 lb/acre when bermudagrass has completely recovered from winter dormancy and is growing vigorously. Repeat applications of 0.5 lb/acre of Cutless 50W should be made at 3-6 week intervals until late summer or early fall.

Poa annua Conversion (Bentgrass, Kentucky Bluegrass and Perennial Ryegrass)

Applications of Cutless followed by management practices, which encourage vigorous growth of perennial turfgrasses will reduce the Poa annua component while increasing the perennial turfgrass component in cool season turf. Poa annua is sensitive to Cutless treatment and is more strongly suppressed than most perennial cool season species. Discoloration of Poa annua can be expected from treatments of Cutless which provide a desired level of growth regulation of perennial grasses. This effect will become visible 7 to 10 days after treatment and will last 2-4 weeks. The degree of overall turf discoloration will be proportional to the Poa annua composition of the turf and the rate of Cutless applied. Discoloration can be minimized by application of low rates of Cutless at 3-6 week intervals. Application of Cutless with soluble nitrogen fertilizers will also minimize discoloration.

Multiple application program
The multiple application program minimizes the Poa annua discoloration by spreading the Cutless 50W applications over the growing season. Make the initial application in the early Spring following resumption of active growth of the grass. Repeat applications of Cutless 50W should be made at 3 to 6 week intervals until late summer or early fall.

Turfgrass Species Initial Application Repeat Applications
Bentgrass Fairways 0.5 to 0.75 lbs/acre 0.25 to 0.5 lbs/acre
Kentucky Bluegrass/Perennial Rye 0.75 lbs/acre 0.5 to 0.75 lbs/acre

Spring/Fall Treatment Program
An alternative treatment program for the management of Poa annua in fairways is to apply Cutless 50W initially in the Spring or Fall followed by a Fall or Spring repeat application. The amount of Poa annua present will determine the treatment timing and rates. Please refer to the Cutless 50W label for more details.
