I spent the day today spraying Embark 2-S on 4 of the 5 school properties I maintain. It runs a 3/5 oz per 1000 sq ft, or up to 2 pints per acre, if you're spraying Kentucky Blue Grass. St. Augustine and Bermuda I believe are at 1 pint per acre. Anyways, I paid $400 for a gallon of chemical, so 2 pints will run me $100. This is SUPPOSED to control growth for 6 weeks. Are your costs for 6 weeks of mowing more than $100 on an acre property? Obviously there are other costs associated with spraying that acre of turf as well, so let's say $200, we'll double the cost of the spray. I just did the trimming areas at the schools, I'm looking to save time and energy more than gas. The higher gas goes, along with all the other costs of operations, and if you bought the PGR in a higher bulk or did some price shopping, I'd bet that the smaller properties are going to start to get to be fairly competitively priced, or at least a close alternative, if you factor in you could be doing other properties at this same time.
