Weeds in the corn

littlepint · May 28, 2016

Hi guys,

I have 1/2 acre of sweet corn that I sprayed with Prowl h20 before it had come up. Now the corn is up, but so are a lot of weeds and grass.
I guess I didn't put enough Prowl h20 on it. Now that I have all these weeds is there another spray for them. The Prowl label says it will
not kill establish weeds.
Thanks

One half acre? get out your garden hoe.24D will get broadleafs. Resolve Q will get grass. However it is only available in a 50 oz(1 1/4 oz/ acre) container that costs 750.00.

Atrazine will work. 1 Quart to the acre in 15 gallons of water.

I spray my sweet corn with a 2 1/2 gallon pump sprayer, walking backwards. I generally wait till it is spiking, but you can spray it up to 3 or 4 leaf, and maybe more.

Yep,attrazine works.And it's cheap. BUT you are tied to corn for minimun 2 years,maybe even 3.It's called 'residual carryover'.

Resolve Q isn't labeled for sweet corn. I asked the Dow regional about it, he said 25% of the guys that try it get away with it. The other 75% get badly stunted or killed corn.

That said, it is about $360 for a 50 ounce bottle here.

The active ingredient in Prowl is Yellow dye #7,, I was involved in a marketing/advertising work shop for Prowl back in the 90's we all agreed that you needed a lot of water to keep your skin from turning Yellow, after that a wave of water was in the label and the H2O was added to the name,,what a circus that was..

Sorry, Steve, I beg to differ. I have light sandy hill ground and rotate half corn and half beans every year. I have used atrazine forever in that rotation and have never killed or stunted any beans except where flushing booms to get herbicide coming out of the nozzles before starting to spray. NEVER go above label rate or you might run into carry over. Chris

Here is what I use
These are per one acre rates.

Impact (or Armeron) 0.75 fl oz
Atrazine 4L 1.5 Quarts
Destiny HC 0.75 Pints
AMS 2.0 lb
Water (gallons at your per acre spray rate)

For 1/2 acre, divide everything by two.

For field application, you want to spray about 15 gallons minimum per acre to get good coverage on the weeds. (you are spraying enough liquid to get the leaves wet/damp)
Since you have 1/2 acre, about 7.5 gallons of mixture.
You will have about 0.44 gal of stuff.
so 7.5 -0.44 = the gallons of water needed
7 gallons of water will be close enough for what you are doing.
Dump the other stuff in starting with the AMS and then the rest and mix well.
Spray when the sun is out so the weeds are actively growing.

Good luck.

I rotate beans, wheat, and milo - I usually plant an 80 of milo and use atrazine on it. Next year - beans it is. I've never had a problem.

The Co-op came and sprayed the neighbor to the south one day this spring when there were 25 mile an hour gusts. This was on the other side of the road from a bean field of mine. I called them - sure enough - atrazine. I chewed them up one side and down the other. They are buying a field of beans this year if that drifted. "Well, we have a lot of acres of spray right now," he said. That was when he agreed they would be shelling out some dough if that carried. Typical Co-op here.
