Is there an optimal outside temperature that this product should be applied to dormant burmuda?
Yes, you can apply MSM during dormancy. You don't want to apply any weed controls to the lawn during spring green-up since this is when the grass is in its most fragile state.
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.
