I know I know, I should have taken before and after pictures, but I didn't, so that's that. Anyways, recapping other threads where I stated last Thursday I sprayed Primo Maxx with the PG Ultra: 1) The turf is not on any fertilization program. 2) I used it only on areas that I would normally have to run a trimmer, trying to cut down the trim time at this specific school. 3) I used the gray (high) rate nozzle, only one, with the stock "t" still in the unit, which gave me a spray pattern 4' wide. 4) I ran in high gear. 5) Chem-Lawn was at this school on, I believe Monday of this week, 6-21, my application was on 6-17. Chem-Lawn only applied broadleaf application. 6) I ran the Primo at a rate of 1.3 oz/1000, using 1 gallon of Primo for 3 tanks of mix. After 1 week, I can say for my situation, I don't believe it worked well with the Ultra. I say this because some areas, around poles, trees, etc., where the pattern somewhat overlapped, the trimmed areas are still shorter. Some areas aren't. The areas where I just went straight along the fence line, there's no difference in the height of the cut / uncut grass this week. This is the area where I ran in high gear, straight shots. BUT we haven't had ANY rain for the last 2 weeks now and it's been sunny with 10-20 mph winds every day, so the ground is becoming quite dry. Even the grass that wasn't sprayed didn't grow more than 1". Now, refering back to what I stated earlier, the turf is not on any fertilization program, which may have some influence. The only reason that I make a reference to Chem-Lawn being there, is because since they only applied a broadleaf application, I've done the same things for some parks that I maintain, and have slightly stressed the grass, especially when it's dry out and no rain or irrigation, which could contribute to the regular "non-sprayed with Primo" grass' length, or nongrowth, but I'd believe it's mostly because there's been no water. I'll give Primo a shot again, because there's too many people that praise it, but next time I'm going to hook up the 200 gallon Lesco sprayer on a little trailer I've got and pull that around with a 4 wheeler, applying the "x" amount of gallons of water that it recommends. I just don't know if there's enough water for consistant coverage with the Ultra. I'll make another report next week, if definately need to trim or not. This week is border line since the grass was so short to begin with.
