David from Tennessee writes,

How much water should I mix with 1 packet of Merit 75 wsp to soil drench a 30" Ash tree?

I am actually going to do a systemic soil drench on three 30" diameter ash trees to prevent Emerald Ash Borer. I ordered the Merit 75 wsp envelope. It looks like I should use 1 packet per tree, but how much water to mix with each packet? I have clay soil.


It states on the label for soil drenching to uniformly apply the dosage in no less than 10 gallons of water per 1000 square feet as a drench around the base of the tree,
directed to the root zone. Remove plastic or any other barrier that will stop solution from reaching the root zone.
