Volkan from Lovettsville, Virginia writes
Quinclorac suggests Methylated Seed Oil surfuctant and triclopry suggests non-ionic surfuctant. When mixing them togethe,r what type of surfactant would be more suitable?
Quinclorac 75 DF should be used with a Methylated Seed Oil (MSO) surfactant such as Prime Source Duo Stick. Generally speaking, triclopyr does not require a surfactant and is normally applied in cooler temperatures whereas quinclorac is applied in warmer temperatures. Using triclopyr with an MSO may be too harsh on any desirable turfgrass. There is a specific window (time frame) these types of products could be applied if they were to be applied together for a situation labeled safe for that type of use. We would recommend contacting your local cooperative extension office for more information on the best timing to treat the specific weeds in your specific region.
