    I just purchased a 2.5 gal. container of Pre-M (Lesco) which I plan to use primarily for my backpack sprayer with Glyphosphate. What's a recommended Pre-M oz. per gallon of water? This is primarily for spraying gravel driveways, mulch areas, building foundations, etc. Thanks.:)

    First fill with one gallon of water. Spray on gravel. Find out how many thousand square feet one gallon covers. Then mix accordingly.

    i use pendulm 3.3 ec, same as lesco's. the lable rate verys, i use 1.6oz per k rate w/ a .75gpm tip. the key to good weed control is getting the product in the soil. what i do, since i use a back pack and can't spray (cost effectivly) 1+ gpm, i try to save all my apps for rain days (mulch, etc, not lawncare), this gives me somthing to do and the product gets waterd in. i sell 3 apps, 1st pre-m, 2nd pre-m, 3rd round up (spot spray round up R1, R2). i also use GALLARY w/ the mix. gallary is a pre-m for many broadleaf weeds, and works GREAT.
