I've been asked a couple times about "what is wrong" with the spot on the 3rd green. The answer; PoaCure. As you know, I've been experimenting with this product, trying different rates and volumes of solution applied. I've learned it's very, very effective. Don't worry however, when product is applied at frequent intervals, low rates to ensure a smooth transition and Poa annua death that goes unnoticed. We expect this product to be available in 2017 and HCC greens Poa free by 2018!
