Yard Mastery Pre-Emergent with Dithiopyr is a granular pre-emergent herbicide used to stop invading weeds and weedy grasses in lawns.
Product Description:
Yard Mastery Pre-Emergent with Dithiopyr is an excellent choice to prevent annual bluegrass (poa annua), Henbit, hairy bittercress, chickweed, and other annuals if you are NOT SEEDING/OVERSEEDING your lawn. It is a primary part of the fall strategy down south for longer protection due to milder winters.
The best time to apply Dithiopyr is when soil temperatures are below 70F and above 55F. This will give you approximately 4 months of pre-emergence protection if you follow the recommended application rate of 4lbs/1,000 sq ft.
You can use this pre-emergent in the spring or fall. However, for the LCN/YM programs, it’s primarily used in the fall for anyone who has reached their annual maximum on Prodiamine. For more information on annual limits for Prodiamine, check this out.
