What is the mix rate when using a 4 gallon backpack sprayer to use Prime Source Meso 4SC Select as a pre-emergent for seeding?

The label mentions acres and a 30 gallon tank.


You can apply Prime Source Meso 4SC at 5-8 oz per Acre for pre-emergent control, which breaks down to 0.11 – 0.18 oz, or 2/3 tsp to 1 tsp per 1000 sq ft. Be sure that you check the more detailed rates on the product label for your specific turfgrass since some grasses require the lower application rates. Usually you will use about 1 gallon of water per 1000 sq ft with a backpack sprayer but be sure you water-in your pre-emergent application after it is made.
