I am looking to treat a 20 acre lake for Pondweed in Michigan. The weeds are pretty severe, covering about 70% of the lakes surface. This lake is a pretty consistent 10' throughout the entire lake. Looks like a Herbicide application would run about $8k or more, which I simply cannot afford.
I'm considering Dye now and wondering if anyone has had experience treating Pondweed with Dye. I think this lake would be a great candidate because these weeds are having to come to the surface from so far down (10'). I am considering this option to treat for the 2017 season by using the product in March / April.
This lake does have a small overflow / outflow. I read on the Michigan DEQ's website that any Dye classified as a 'Herbicide' (like Aquashade) cannot be applied to a body of water with an outflow. It seems as if I am able to use another brand like 'Cygnet Select' since it is not labeled as a Herbicide. Can anyone confirm?
I'd appreciate any input or to hear about any experiences.
Thank you,
Dan
Interesting. I did not know AquaShade was classified as a herbicide. I've never seen it actually kill any weeds and I thought blocking sunlight was its only function. Last time I went to buy it at Rural King they had some other brand on sale for $18.something a gallon so I bought 2 gallons. It looked like Aquashade and colored the pond the same. They also had it in black dye and I wondered if that might work even better.
