What do you think the best option for a person with just a backpack sprayer? Dimension liquid with a backpack sprayer or granular with a spreader. I'm thinking about going with Dimension liquid in the 1/2 gallon or a locally mixed Dimension granule (see below). I plan on using it on two properties. Both are around 8 to 10k sqft. I think the minimum application rate is 1 gallon of water per 1000sqft. If I use more water to mix, it will take a lot of refills using a backpack sprayer.
