Thanks guys. I appreciate the responses. Greg, with the Reward do you notice any regrowth later in the year? Do you do any underwater injection of chemicals in deeper water and if so do you notice any advantages over simply applying chemicals to the water surface?
We want to keep the primrose for fish cover and for nutrient uptake. In past years it hasn't gotten too bad.
I talked with the people from SePro on friday and they recommended that I use Sonar Q at a rate of 10lbs/surface acre. I talked to a guy recommended to me from the makers of Aquathol and he recommended using Super Aquathol K pellets at a rate of 6.6# per acre ft.
