Brent from Hampstead, Nc writes
MSM Turf Herbicide is best applied when target weeds are actively growing and healthy, usually best between temperatures above 55 and below 85. Per the product label: Do not apply MSM Turf Herbicide to turf under stress from drought, insects, disease, cold temperatures, high temperatures of above 85°F on cool season grasses, or poor fertility as injury may result.
