    What are you trying to control? Dollar spot? Also what product are you spraying and what equipment?

    Thanks for the upload. This confirms what I have always practiced. I do not expect good control from flood jet nozzles run at high speeds and low volumes. For fungicides, which I do apply regularly, those go down in 2-3 gallons per M, XR Teejet nozzles and at sufficient pressure to penetrate the turf. Normally that is 60-80 PSI and no more than 5MPH. If I wanted to win a race, I would get out of the lawn business. All of the pesticides go through field testing and are applied in a very specific manner. I want to achieve the same results that got the product approved and registered. I know products are applied through flat fan nozzles, at a specific pressure, and at an adequate volume per acre when they are being evaluated. What is done with them when they are released to LCOs is another story.
