I am no expert but have spent a lot trying to be one.
I sprayed with Cutrine plus...poor perfromence... the next year under advice from someone who knew more than me...I used it again, started earlier, higher rate, more often....same result only more expensive.
I changed to granular...figured why not...same result.
IPut in Grass carp in July....they have really done a lot of good already and they were about 8 inch fish when I put them in. I put more than some folks would but its still within the recs I have seen, just the high end...I put 10/surface acre.
