   On Wednesday of this past week we sprayed Penterra and Humawet followed by 8 min H2O on our A-1 Bent greens (Wetting agents to help with LDS). On Friday we applied Daconil/Fert. We hand watered in front of the sprayer for AM prep. The sprayer caught up to the hand watering guys and sprayed directly after they were watered on the last 6 greens. This being said, later that afternoon I noticed an irregular pattern of the Dye on the last 6 greens. Where the green was hit with hand water it looked as if there was no dye or Dac. for that matter on the leaf surface. My question is, could the wetting agent still be on the leaf causing the chemicals not to stick? Reduction of efficacy from the Daconil?

   Probably more like the leaves were covered in water droplets, and the extra water applied with the sprayer caused the mix to run off the leaf blade. Kind of like when you spray in dew.

   I would agree except we have made plenty of foliar apps just after hand watering without this occurring. I don't recommend doing this but that's the way higher powers choose to.
