Combine Land and Weed Management for 2019 Success

Mark Glady
Regional Agronomist
It’s time to formulate your land management and herbicide programs for 2019. Here’s how combining these strategies can provide optimal weed control without sacrificing sustainability.
Herbicide choices
If your 2018 herbicide program adequately controlled weeds, you’ve dramatically reduced the weed seed bank potential for next year’s crop. If some of your 2018 herbicide choices didn’t work as planned and you have weed seed that scattered when you harvested, you’re going to have some challenges come spring. This will make applying a residual herbicide at preemergence particularly important.
One option is Threesidual™ herbicide, which contains three active ingredients from three different sites of action to manage weeds in field and silage corn. Add InterLock® adjuvant to the tank mix to achieve optimal deposition.
Tillage system
If you are a no-till soybean farmer, it’s important to do a spring burndown with some glyphosate and dicamba prior to planting. And you should apply a broad-spectrum residual herbicide such as PREsidual® herbicide to prevent weeds from emerging. If you use conventional tillage, you will eliminate those weeds during the tillage process, so you don’t need to spray before you plant. However, you will need to apply a preemergence herbicide such as PREsidual herbicide, Charger Basic® herbicide or Dimetric® EXT herbicide, mixed with InterLock adjuvant.
Sustainability goals
Conventional tillage, of course, churns the ground up, which can lead to erosion, versus no-till, which reduces it. However, no-till requires more herbicides, which are safe when used according to label directions. If you are a conventional farmer who is trying to work some no-till plantings into your operation, be sure to use a broad-spectrum herbicide program that manages all weed species. Such a program might include applications in addition to the normal spring and early-summer spray times to achieve effective control.
Likewise, planting a cover crop can be a good choice for no-till farmers, since it can help reduce soil erosion, preserve topsoil and create better soil structure as a result of its active root system development. Cover crops can also be used effectively with conventional tillage.
Agronomist recommendations
Remember that controlling broadleaf weeds such as waterhemp or ragweed can require a different herbicide system than when managing grass species such as foxtail. If you haven’t done so, let your local trusted advisor know specifically which species of weeds and/or grasses were problematic in your fields this season. Then determine which products can manage the issues and what land management practices will best complement that strategy.

Season 15, Episode 4: Real Talk: Sustainability and Modern Farming

Joel Wipperfurth
Director of E-business
When you think of the word “sustainability” in the realm of modern farming, you may not realize that many farmers have already adapted everyday sustainable practices. It can be a topic of contention, but on this episode of The Deal With Yield, host Joel Wipperfurth and guest Molly Toot, senior director of sustainability at Land O'Lakes, dive into farmers’ common sustainable practices and the tools available to track their sustainability journey.

Dial In to Data Quality

Steve Anthofer
Answer Plot Operations Sr. Manager
Winter is here and it’s time to formulate a farm plan for next season. Take time to review data from 2018 and use it to make decisions for 2019. Here are some ways to help ensure your data is as accurate and information-rich as it can be.
1. Demand data that’s replicated.
Agronomic data that’s backed by extensive replicated trials helps verify whether variations in that data are due to error or to the effects of different treatments. Data that undergoes a quality assurance process gives you the confidence to use it to make critical decisions. WinField United Answer Plot® data is derived from high-quality, replicated research with built-in controls that help us understand product performance so we can offer recommendations you can trust.
2. Know the limits of crowdsourced data.
Crowdsourced data can tell you what happened when a product was tested, but not why it  happened or how it happened. Knowing the kind of environment in which a product performed well, and how it interacted with other products, are steps toward better predictability. Crowdsourced data doesn’t offer that level of specificity.
3. Request data that’s prescriptive.
Farmers need information that helps them make decisions about future crops. Conclusions made about commercial products that have been in the market for a while can be useful if you continue to use those products. However, those same conclusions have limited value when you’re considering new products you haven’t yet used on your farm. WinField United delivers insights on many seed and crop protection products at least a year ahead of data that is crowdsourced.
4. Insist on data that represents your fields.
Notice I didn’t say, data that “is specific to” your fields. Using on-farm data or research from nearby fields used to be the standard. Now, using environmental characterization, we can identify research from locations nationwide that can represent the average environment of a given farm.
Said another way, when you only use local data, you make inferences based on past performance to represent next year. But next year is probably going to be a lot different from this year. By using data from a field in another location during the same year, we can represent the average of your farm’s environment and use that information to make decisions.
5. Work with your local trusted advisor.
Meet with your advisor now to navigate Answer Plot data and start making plans for next season. Every year is different, and your advisor can recommend the tools and insights needed to help you navigate your data and use it to start 2019 off right.

A Winning Option for Spring Wheat

Mark Torno
CROPLAN® Diverse Field Crops Marketing Manager
Reliability and stability are key ingredients for wheat seed, particularly if it is grown on variable soils. And having two varieties in one bag — pairing one that has a particular strength with another that has a completely different but complementary one — can help.
A WinPak® spring wheat variety from CROPLAN® seed offers a unique combination of two varieties that provides an exceptional level of stability throughout the field. WinPak varieties work together to increase yield potential by reducing risk from field variability, weather and soil conditions, and disease complexes. If you’re looking for a wheat seed option that performs well in variable conditions and under environmental pressures, here are some reasons to consider planting a WinPak variety.
There’s the value that comes with achieving the highest yield, and then there’s the value that comes with reliability and consistency. That’s where a WinPak wheat variety proves itself: We combine two products that work together to increase yield potential on tough acres while maintaining yield in higher-producing areas. Data has shown a synergistic effect that comes from having two types of seed in the bag. When one variety may not be at the top of the list in certain aspects, the other variety can compensate.
More genetics
No farmer gets excited about cleaning out the seeder and switching between varieties. Even though a farmer might want more genetics on the farm, it’s a lot of work that takes up valuable time. A WinPak variety provides two genetic backgrounds, and farmers only have to plant once.
If one seed component in a WinPak variety has a stronger standability rating than the other, it tends to bolster the second one. This nets out better than separately growing a variety with a less-desirable standability rating and another with a strong rating.
The power of two
CROPLAN currently offers one spring wheat WinPak variety, CP3888, which is a combination of CP3616 and CP3504. This WinPak variety has a number of features and benefits, including:
  • Excellent yield potential, strong protein
  • Strong disease package, great candidate for fungicide applications at flag leaf and heading
  • High response-to-nitrogen rating for peak protein advantage
For more information on WinPak varieties from CROPLAN seed and new varieties that are in the works, talk with your local trusted advisor.
