How much powder per quart of water for the concentrate, and how many ounces per gallon to dial in on the sprayer? I have 28 feet of 8 ft tall "Snow on the Mountains" which get infested every year with the span worms of White Tipped Black Moths. The span worms can strip the shrubs bare, then metamorphose into moths, which lay more eggs which hatch into more span worms. The typical 1 gallon pump hand sprayer takes forever to treat this much shrubbery.
Unfortunately most hose end sprayers only work with liquid and not a dry product like merit. It typically will not mix very well with the water. Although it does take longer, a hand pump sprayer is much more effective and ensures the product is mixed thoroughly and applied evenly. We do have many inexpensive back pack sprayers which will allow you to apply 4 gallons of solution at a time fast and efficiently.
