SK,
Welcome to Pond Boss and especially welcome from another pond owner in W Michigan. I'm glad you found the forum as there is a wealth of information here. What makes this forum so great is that there are many experts who are doing things in pond management that are way ahead of the curve so to speak and you really will learn if you search for answers to your questions.

Google search using your search term and the word pondboss is the best way to search for answers.

Tell us more about your ponds! You have 2 of them? How old are they? How were they dug? What is the soil like? Is it a lined pond or compacted clay? Do you have a way to add water in the dry weather we have been having this year so far? What is your depth like and your clarity?

Have you been watching the ponds long enough to remember a time when you didn't have these weeds?

Scott (esshup on the forum) has helped me a ton when I had my outbreak of eurasian milfoil and your picture looked exactly like mine. It took over half my pond 2 summers ago. I used Sonar to kill it with calculations at the lower PPB to leave the other pond weeds untouched.

I have some left over sonar that I have no use for. I would part with it for a significant discount. Esshup will probably be happy to help you calculate how much you need and you will likely need more than I have on hand but you can easily order a small amount (8 oz bottle is what I bought) from him via his online store.

I have a .2 - .25 acre pond and 1 oz was just about perfect. I ended up treating in August and after about 6 weeks could see a very good kill. I ended up retreating the next spring just in case...

I'd love to learn more about your ponds and share some things about my pond and what makes ponds in Michigan unique. I'm still at the stage of building forage as my pond was recently renovated and I had the joy of starting out stocking with a empty puddle...*(except the hardy goldfish which somehow made it through the drain down, excavation, and refill smile ....)

What fish do you have in your ponds?

Hope you check back here on the forum often.
