Pond Boss Forums AQUATIC VEGETATION Controlling unwanted plants American Lotus Control

I was just wondering if there were any permanent options for american lotus control. We are looking at the herbicide option for control, and would like to use a granular herbicide if possible.

I can't help you with this, but you might send Kelly Duffie a PM to see if he can help. Another one might be Esshup, he might be able to steer you in the right direction of who would know. Thought I'd throw this out there before this post disappears off the grid.

Welcome to the forum!!!!

I don't know of any granular herbicides that are effective. Liquid? Yes.

American Lotus will grow to USDA zone 4. I don't think it matters whether it's lily or lotus, but are you sure it's lotus? Lotus does not have a cleft leaf, lily does.

Like Essup, I don't know of any granular herbicides that are labeled for or effective on American lotus. Even if there were, granular treatments would be a much more expense and a less efficacious option in comparison to topically-sprayed liquids.
I would suggest topical-applications of aquatic-labeled herbicides that contain glyphosate, 2,4-D, triclopyr or imazapyr; any of which would work with varying degrees of success. Remember that such treatments will only affect the plants whose pads are on or above the water's surface at the time of application (assuming the pads receive adequate coverage). Any submerged pads or newly germinating seeds will require future applications in a long-term program to interrupt the population's seed-production cycle.

esshup, yeah we are positive it is American Lotus. We are planning on using a triclopyr herbicide. We are hoping to do a second application a little later this summer to really lay down the lotus and hopefully control the problem for the year. Thanks for the help! Just out of curiosity, are there any major noticeable after affects of triclopyr affecting trees near (around 10 feet) from shore?

As long as you follow the label for application rates, and don't spray the trees directly, I wouldn't have any concerns using it.
