I AM LOOKING FOR A GOOD PRODUCT TO GET RID OF CAT-TAILS AND SOME OTHER VERY NASTY WEEDS OUT OF A DITCH.
I HAVE SPRAYED CROSSBOW,ROUND-UP AND STILL NOTHING.
I WENT TO MY LOCAL CO-OP AND THEY SUGGESTED ERASER?

WHATCHA THINK?

I thought this sounded like Roundup with a name that included that famous "41%". But who would have thought that the marketing freaks could actually stoop this low?

This particular off-patent RoundUp ripoff is only .96% glyphosate. It sounds like the local co-op is more interested in making money than helping the customers. This stuff would have to be awful cheap to be considered a good value. RoundUp Pro is more than 41 times more concentrated and the water that this stuff is made with probably isn't worth the difference.

Cat Tails are tough. Give me a little time for this one. Diquat gives good results & RoundUp is rated better. Removal of the rhizomes is the surest bet of all. If you tried RoundUp & it didn't work, I'd suggest there was either a timing issue (likely) or perhaps an issue with the rate or applicator error.

Aquatic herbicides require a special liscence & a permit here in CT. Your state may have similar requirements. Have you checked? Of course not all areas that support Cattails are actual aquatic by definition, so you could be OK. If they're in a drainage ditch that was treatable because it was dry at the time, you may have your answer right there. Drier soils won't sustain the growth needed for good herbicide efficacy.

Let me sleep on this one.

Hey MoCut,

How long after you hit the Cattails with Crossbow before you tried the RoundUp? Crossbow (designed to control dicots) shouldn't have had much effect at all. If you really hit them with it, they may have been in shock & therefore not translocated the Roundup.

I hope the link takes you to Vanquish. Take a look and see if you can do it. Weedmaster used to be labeled aquatic, so you may find some Dicama (Banvel) or Diglycolamine (Vanquish) formulation you can use in the particular area you want to treat.
I've sprayed thing that were standing in water by bending the tops over to the bank, thus avoiding getting pesticide in the water. I'll stand in the water to spray things at the edge, spraying away from the water.

Cattails won't be controlled by herbicides line Banvel. Cats are moncots (like grass & sedges). Banvel and Crossbow are for controlling Dicots or broadleaf weeds/trees.

Check the following link for more mechanical & chemical control measures.

Mocut, Are these cat's in standing water? If so, see the part about cutting below the water line to drown them.

Could be why I never had much luck with chemical control on them, huh?
