Salvania
 

Unfortuantly my marsh is now full of it. Thoughts on how to get it out of my marsh and open the water back up?

A mixture of 2-4-D and round-up.

Chemcal called Reward.

Noxioux Aquatic plant specialist for the state of Louisiana is in abbéville. They will know what will control it, salvinia is a problem nationwide and will never be eradicated.

Unless you kill every piece it will come back. The two best things that can rid salvania is a flood where it all runs out, or a drought and it dries up and dies

Better hope for a hard freeze this winter also.

^^^^

The chemical that kills it is expensive and it will come back, we have a canal leading to our pond from the river, we just run the canal and clean it out real good then put mud boat in the mouth of the canal leading into pond and pump it all out of the pond, we get a couple other boats to run around the pond and keep it stirred up while pumping. It actually works quite well, took us a couple years of fighting with this crap and trying everrything u can imagine to get rid of it and this is the best thing we have come up with so far.

we just drive the boat against a tree and use the boat to pump it.

Once you get it out use some containment boom to help keep it out. Also here in Terrebonne there are locations that are "growing" salvinia weevils. Check around your area to see if there are any near you.

Yes, 2,4D will kill it. Will have to spray it twice more than likely to get to the plants underneath the top layer. Like said above if you can get some containment boom to keep it from coming in that works well. Good luck this stuff is the devil and has zero wildlife value. The 2,4D will also kill your favorable plants if you spray it on them

Reward is trade name for Diquat. it will burn it back, not kill it. In my many years spraying ponds and lakes on Golf Courses, I have never had Reward (Diquat) kill anything and it is pretty damn expensive. Also, do not get caught spraying Roundup in water. It is not labeled and can come with a hefty fine. The Aquatic Glysohates like AquaNeat, Aquamaster are basiccaly Roundup with a spreader sticker added so it will stick to the plants leaf tissue. 2-4D will also help. Mix some 2-4D with a Clay floor dry in a bucket, and chunk it out in variuos spots, this will allow you to get the chemical below the surface. also mix it with the Glysophate for spraying on top

X2 on the chemical boom we also use them after clearing the pond.

I just spoke to a chemical salesman yesterday about this problem. Rodeo is an aquatic glyphosate which is the same as Round-up with and aquatic use label. Diquat is an aquatic 2,4-D which is the same as 2,4-D with and aquatic use label. As stated before, don't get caught using chemicals not labeled for aquatic use. Do a tank mix according to the labels. You will have to do numerous applications as it's not going to be a one time deal. Once you have a knock-down reapply anything remaining. Keep doing this until it is gone.

I have talked to a few people myself this morning and thanks guys for all of the advice. This is not going to be an easy process. I had what was going to be a great freshwater area for duck season this year. Now I guess we will have to see.

Any idea of stores near me in Houston or Lake Charles that would sale these chemicals?

probably any feed store

G&H in Iowa

I just went to tractor supply in Tomball they had everything. Nice way to spend $1,200.

Ouch
