Corn Pesticide Cost

in-too-deep · Mar 25, 2015

Wondering what a person would pay per acre to control weeds in field corn. At my old job we sprayed Roundup and a residual and various surfactants. Just one pass, but I can't remember what the exact products were. Ignite if it was LL corn. Used Status to kill volunteer RR soybeans in RR corn. Laudis maybe for the residual control? Anyway, what's a ballpark figure? NW Minnesota. 80 to 90 day maturity expecting 150 to 180 bpa. Thanks!

Last year I sprayed our corn with 48 oz./acre of generic glyphosate, along with a product that was liquid ammonium sulfate and a water conditioner for about $7.00/acre (just the chemical and AMS cost, not the application cost).

I spray atrazine and generic Prowl pre emerge at a cost of about $10 an acre. In most cases,I don't have to clean anything up with Roundup.

One thing to remember for corn weed control is this: if you are killing weeds in a standing crop you are already behind. Corn does best when there are no weeds to compete at any time. You never want to hold corn back. If you do anything to set corn back, or even to just stop growth for a few days you will cause more economic damage than if you had spent more for early season weed control. While there are "cheap" ways to control weeds (post) in corn they are designed more as a rescue treatment, NOT as the first-line way to do it. Your post spray should be as a cleanup, not as the only herbicide plan you have. Mike

Good advice. My old boss would always want to spray before any weeds showed up. Makes sense. How come people don't use more pre emerge? Expense?

Spray on then work in with field cult and plant? 10 gal/acre or more?

No. I go back after I plant and just spray over the top. I use 20 gallons of water. I had one field that got away from me last year and everything was up before I could get there with the sprayer,so I added a quart of Roundup. The Roundup took care of what was up and I had residual from the atrazine and Prowl.

Interesting. Thanks for the info!

Well I will second Mikes post. You should spray way before any weeds are showing. Even the smallest weed steals nutrients from the corn.

Also you are asking about herbicides not pesticides. I thought your were going to asked about root worm control.

Depends on the product- some is pre-plant incorporated.

Thought the same....pesticides for bugs, herbicides for weeds. Technically I guess every thing is a pest.... :lol:

Weeds and bugs are pests. Insecticide for insects. Guess I should have said herbicide.

Goes to show what a joke an applicators license is.
