The present embodiments provide methods for selectively controlling weeds in improved turfgrass, comprising applying
clomazone to the improved turfgrass. Until now,
clomazone has not been considered for use in improved turf due to unacceptable / anti-aesthetic bleaching properties, which are overcome by the methods described herein. The methods include consideration and management of
clomazone application timing relative to turf type, turf
dormancy, and overseeding timing and planting depth. The present methods provide the use of clomazone in the control of Poa (
Poa annua and P. trivialis) in warm-season and cool-season improved turf types, such as Bermuda grass,
Zoysia grass, St. Augustine grass,
Centipede grass, Ryegrass, Fescue turf types, Kentucky Bluegrass, or mixtures of thereof. The methods further facilitate the use of clomazone to control Poa and other weeds in overseeding practices, such as overseeding with Ryegrass or Kentucky Bluegrass. These methods achieve desired turfgrass tolerance and turf aesthetics while still achieving desired selective
weed control
efficacy, supporting a new use for clomazone in improved turfgrass markets.
