Gary from Houston, Texas writes

I mixed 1.0 oz of msm in a three gallon sprayer. Will this harm my St. Augustine grass?

Answer:

Per the product label, some chlorosis or stunting of the turfgrass may occur following application of MSM Turf Herbicide at the correct rate.  1 oz. is the rate for covering an entire acre.   If applied to an area smaller than an acre at that rate, yes, it can harm your lawn. Per the manufacturer, their recommended rate to use for spot applications is of 0.1 oz per 4 gallons of water, which can be easily measured with their measuring device provided.
