Water Hyacinth and Other Invasives

[meat killer 86]

Water hiacinth is some crap!! But we use Diquat if we spray from the boat. If I spray from the plane I use generic roundup. 1 gallon to the acre. Works great and not to expensive. Spray no more than2 times a year. Any more than that then you start having other plant invasive species such as salvania and pickerel weed start to magnify. This is just what we have learned and do in our marsh. It changes from time to time but I know everyone is going to have their different solutions.

Biggest thing is to stay on top of it year after year. If you miss a year it may not hurt. But anymore than two years and it's harder to get back. Best time to spray is in late July. You can kill it and shouldn't have any serious growth for the rest of the year because he growing season ends in September.

Thanks for the info, we seem to already have the pickerel weed, sprayed that as well obviously. I've been using 2-4-d, any reason you don't use this product instead of the roundup or diquat? Do you have ditches and canals into ponds boomed off? Was thinking I need to put in 4x4's, rope/boom to prevent new stuff from coming in with tides. I assume yall are tidal too? It seems I have it made with round shaped/non broken ponds, but some of the ponds that are mostly broken marsh, with scattered islands and acres big it can be overwhelming spraying such a large area.

We are not tidal. We are an impoundment but we have it all. This year I didn't use 2-4D because I made some phone calls to Rockefeller and talked to "The Man" and he said by using straight roundup is better. If you mix the 2 then you get to a point where one fight the other and only one chemical kills the plant. Then you have waisted money on chemical that didn't do anything. Make sense?
So we went extra heavy and it did a jam up job. Smoked everything. No complaints.

I'm not sure exactly how your stuff is but all you can do is spray and nick it back. Sounds like the tidal waters move your grass around a lot. Just kill what you can and keep at it.

Meat, looking at glosphyte (round up) online I see rodeo is the popular aquatic one. Yall using that or regular old round up? I'm assuming mixed maybe 2-4 oz per gallon of mix?

No we use just generic. The rodeo is supposed to be better for aquatic plants but in all the yrs I have been spraying we can't tell the difference. The rodeo is way more expensive so we just use generic. We don't have issues with killing the plants. They all die!!!
