Crop Talk – Protecting yield with fungicides


Hello all!

So far this year, the corn and dry bean crops are looking great, so today I wanted to talk about protecting yield with fungicides.

We are currently in a high yield environment, very similar to 2012. We are receiving lots of heat units and the crops have responded accordingly. I believe this would be a great year to look at a fungicide at tassel in corn and the beginning of flowering in dry beans. Both applications have a great track record of improving yields at harvest.

The fungicide I recommend on corn is Headline AMP. There are many trials that show very consistent yield results, along with improved standability, on corn treated around tassel time. The key point here is to treat prior to pollination or immediately after pollination. Spraying while the plants are actively pollinating can result in poor pollination, leading to yield loss.

In dry beans, I recommend using Priaxor at the beginning of flowering. Dry beans are particularly weak against diseases and the application of a fungicide is very beneficial, eliminating stress and increasing overall plant health which will lead to increased yields. Consider pairing a foliar product, such as Max-IN Copper, for better results.

Speak with your local Farmer’s Coop agronomist for more info.

Crop Talk – Protein in wheat

It is pretty well-known that the protein in the dryland wheat this summer hasn’t been that great. We have had numerous discussions amongst ourselves about it and I thought it might be a good topic this week to discuss.


I think the low protein comes down to about 3  factors:

  1. Fertility – Nitrogen and sulfur are the most important factors in protein content. It really isn’t enough to just apply nitrogen to achieve a certain yield goal. We should be factoring in our desired protein content. But if the plant can’t utilize the nitrogen, what is the point? That is where sulfur comes in. Without adequate sulfur, plants can’t use nitrogen efficiently. Every application of nitrogen should contain some sulfur.
  2. Stripe Rust – This summer we had the worst outbreak of stripe rust that we have seen in a very long time. While we typically associate rust with yield loss, I don’t think we can ignore it as a possible factor. Any stress put on the plant will adversely affect performance, so why should protein content be any different? It is no coincidence that the irrigated wheat is testing higher for protein. The majority were sprayed with a fungicide at the first sign of rust.
  3. Freeze damage – It is hard for me to point at this one as a definite factor. The primary reason is there were many fields that never had any signs of damage, yet the protein content has been consistently poor on the dryland acres. However, like stripe rust, it can’t be ignored as a potential factor.

Instead of focusing on just one, I would say it was likely a combination of two or three of the above factors.

If you would like to discuss plans for next year, be sure to contact your local agronomist at Farmer’s Coop.

Upcoming Event: Answer Plot Session II

Quick reminder: On Friday, July 22nd, the 2nd session of WinField’s Answer Plot will be held 3 miles south of Gering, starting at 9 AM.

They will be covering a wide range of topics including wheat seed treatments, tissue sampling, and corn hybrids, including Dekalb and Croplan. If you have never attended before, there is a wealth of information to be gained. Also of note, the Gering plot is the largest corn research plot EVER planted in the NE, WY, KS, CO, & MS area.

Below is a brief overview of the Answer Plot goal:

If you are interested in attending, contact your local Farmer’s Coop agronomist for more details. If distance is an issue, I’m sure you could hitch a ride with one of us.


Crop Talk – Weed control following wheat

Hello all!

Wheat harvest has officially begun and that means it is time to start thinking about fallow spray again. There are lots of weeds under the canopy that will start to rapidly grow as soon the wheat is harvested. A good rule of thumb will be to wait about a week or so following harvest before spraying. Doing so will allow the weeds to regrow if they are clipped off by the combine.

Here are some popular picks:
2,4-D LV6 – I think we are all familiar with 2,4-D at this point. It is still a go-to option on fallow acres because of price point. It will get the job done under most circumstances, but don’t count on it against kochia, that’s where my next pick fits…

Distinct – I like to think of Distinct as dicamba on steroids. It has an additional active ingredient (diflufenzopyr) that drastically increases the knockdown power of the dicamba. For those of you familiar with Status, you know how effectively it works on kochia, lambsquarter, etc. Distinct is Status without the safener.

Atrazine – I like to add atrazine on dryland acres that will be fallow for the upcoming year or irrigated acres that will be corn. The goal is to extend the weed control to potentially eliminate an extra post application later in the year. Also – I can’t stress this enough – resistant issues are a lot less likely to creep up with pre-emerge herbicides.

All of the above options should be tank-mixed with RoundUp.

As usual, if you have any questions about these chemicals, or other available options, call your local Farmer’s Coop agronomist!
