Pond Boss Forums AQUATIC VEGETATION Identifying plants HELP...what pondweed is this and how to erdicate?

Hi,

I have a pond located in Vermont that's 1/2 - 3/4 acre average 4-6' deep with some center spots 15'+. This summer I have a new pondweed that's stringy/bushy and appears to be either Sago or Widgeon. There are little round seed clusters at some of the tips of the stalks. The clusters are roundish, pinky nail size and have approx. 6 "seeds" that look like sesame seeds. Can someone help me with a process to get rid of this weed? The more I read on this website, the more questions I have on the best way to handle this problem. The pond has LMB and a variety of other critters. I have good pics, but don't know how to attach them. I read the FAQ and don't have my own site or URL(?) to download from. Maybe I can email to someone who can help? Thanks in advance.

Thanks Ric...hope this one works.

Looks like Sago to me... I use 5:1 Chelated Copper (Pondweed Defense) to Diquat (Reward). It does the trick for most pondweeds (Widgeongrass included). So either way, this mix should get you there. Just follow the label on the copper to get your amount needed, then add Reward at 1 part for every 5 parts copper.

That was assuming you can get diquat in CA

Thanks Justin...had a few questions.
Is the treatment a spray?
What is effective method? Do I spray surface or put wand into water near bottom?
How do you determine the spray amount if you can't see it?
Will I need a surfactant?
What about aquathrol Super K granules? I would rather use a granular type make it easier. The more I read, the more products I see and more questions. Thanks for any advice.

I use a topical spray, the chelated copper will get to the weeds just fine. As far as spray amount, figure the square footage of the area to treat (length x width), then divide that by 43560. this will give you surface acres... (1 surface acre = 1 acre 1 foot deep). the product label will tell you the rate by S.A.'s. I havent used much aquathol granules, they may work but I'm not an expert. Ive stuck with what does work - chelated. As far as a surfactant, I dont usually use one in this mix, but you may want to-- it cant hurt.
