OK, I'll say it. Granular is terrible and if he is only paying $2 more a bag he is using terrible granular. I have an account that will only let me use granular because they think it is "safer" than liquid because it does not have an odor. I cant get them to drop me. I raise prices thru the roof and they resign. This site is 4 acres. So here is my opinion. The ONLY granular that ever worked was old momentum with chlopyralid. Guess what you cant get anymore. Granular apps will give you minimal results. Here is the kicker in my opinion. What about a spot spray? IPM? Scouting and treating? Why blanket every property every time? That is just plain irresponsible. I hate using granular for so many reasons. Find a real applicator. Dont let him feed you a line of crap about getting out and applying to wet lawns. Keystone-- Find a used 50 gal or buy a synergy until you can justify a larger purchase. I got my first 50 gal sprayer for $200 and 4 years later it is still in production.
