Gly-Resistant Weeds---uh-oh

[jmb4wd]

Last year the brothers who farm our land, had a huge crop of these weeds come up in the cotton they had planted. I think they applied about 3 or 4 applications of gly on the fields and it never phased this stuff. They had it sent to the UT Weed Department (not that kind of weed department), and it took them a while to identify it. For the life of me, I cant remember what they called it, but I know that there was nothing that they could spray the cotton with that would kill this weed and not harm the cotton.

Fast foward to this year, I have about 1500 feet of fence line I keep sprayed behind my house, and I usually keep my spray kind of hot like 2.5 quarts per 20 gallon of water. This spray dont even burn the leaves of this plant.

I was talking to the farmers the other day and they said that there was grant they could apply for that would provide assistance in keeping this weed out of there fields. It said in the grant application that laborers with garden hoes (aka, our Mexican friends) would keep the weeds at bay!! Is that not crazy that they are going to attack theses fields with garden hoes!! It make me laugh to say the least.

Here a couple of pics of a small plant coming up in my sunflowers, and I will update as it grows.

Oh shat,resistant to gly???Only thing Ive run into is Nutsedge,but that aint nutsedge.Quailman will know.

Looks like Marestail, and yes, it is known to be Glyphosate-resistant. The big issue in the Southeast is Palmer Amaranth. It is mainly confined to southwest TN, but I do know of a couple of fields in Rutherford County that have Gly-resistant Palmer Amaranth.

If you go by a local golf course the Superintendent can tell you what to spray Nutsedge with and it only targets Nutsedge.I used to know the name of it...but can't remember now?

If you are wanting it gone. ;)

I talked with him today, and yes he said it was Marestail.

He also told me that in the UT study that you could have a field 99% weed free and and have one male and one female Marestail and it would produce over 600,000 seeds!!!

He said that Marestail, and Pigweed were the two weeds that they have been fighting, that seem to be gly-resistant.

He also told me that in Arkansas, that they have been using hoeing crews to rid the field of pigweed, and that they are loading it on trailers and burning it in the corner of the field. If you hoed the plant up and let it lay, the taproot would resprout and root itself again. Some of the taproots are known to be over 6 feet deep!!

Yes, the pigweed you're talking about is Palmer Amaranth, and it is a nightmare to control in some areas. There are several other Amaranth species that are commonly found as "weeds", such as red root pigweed, spiny amaranth, and smooth pigweed, but Palmer Amaranth is the biggest problem right now.

There are some other herbicides that will kill marestail in early stages, in certain crops. This is one bad by-product of the roundup-ready predominance, using the same herbicide over and over coupled with no-till after no-till. Many farmers are starting to go back to non-GMO soybeans and corn and other classes of herbicides.
