Get a Jump on Spring Weed Control

In the battle for clean fields, mature weeds are equipped to win. Waxy cuticles, hairy leaves and increasing herbicide resistance make them formidable foes. That’s why it’s important to start weed-control programs early, says Rodney Tocco, crop protection technical marketing specialist, WinField. “Ideally, you should tackle weeds when they’re under four inches tall. Any taller, and weeds are much harder to control and likely causing yield loss in your fields.”
 
Tocco adds that mounting glyphosate resistance is prompting many farmers to return to preemergence herbicide applications. “It’s critical to clean up fields early, before resistant varieties get a foothold. You can’t count on in-season glyphosate applications to control some of the more stubborn weeds.”
 
USE ALL YOUR TOOLS
There’s no such thing as a silver bullet for managing weeds, says Tocco. He urges farmers to make use of a variety of weed-control tactics to find the best solution for their specific challenges. He outlines the elements that matter most in effective weed-control plans.
 
  • Timing. Consider both pre- and postemergence herbicide applications to keep weeds from getting the upper hand.
  • Rates. Check labels for target pests and crops.
  • Carrier volume. Increase gallons per acre for better postemergence coverage.
  • Adjuvants. Maximize spray mixture efficacy with the right adjuvants and water conditioners.
  • Nozzles. Match the right nozzle tips to the spray situation for optimum deposition and coverage.
  • Modes of action. Combat weed herbicide resistance by rotating herbicide modes of action.
 “An early start and careful attention to the details are critical to help protect yield potential this year,” says Tocco. WinField regional agronomists are ready to help you fine-tune programs to combat weed challenges in your area.
 

4 Tools to Help Plan for Success

Answer Plot®
Research Team
With low commodity prices causing concerns this past fall, farmers are looking for ways to receive top returns on their input investments while getting optimal performance from each acre.

WinField has the proprietary tools to help you design an individualized prescription for every field based on this year’s insights.

1. TRUSTED ANSWER PLOT® DATA
With hundreds of replicated trials that include a wide range of products at nearly 200 locations nationwide, the Answer Plot® Program provides one of the industry’s most extensive data sets for use when planning. Based on sound scientific practices and meticulous attention to detail, Answer Plot® data is the basis for customized R7® Tool insights and recommendations that will help you identify the right input investment for each of your fields.

2. R7® TOOL INSIGHTS
Use the R7® Tool to help set realistic yield goals for next season. The R7® Tool allows you to see your fields like never before; viewing field maps with historical data, soil variability and other primary information. Based on each zone’s conditions and precise local Answer Plot® data, you can work with your regional agronomist to develop a customized plan for your operation, including population counts, and fertility and crop protection recommendations to increase potential return on investment.

For current R7® Tool users, you can evaluate the 2014 season with field response and profitability maps to help improve productivity potential and profitability potential next season.



3. CUSTOMIZED TOP 10 HYBRIDS
The Top 10 function within the R7® Tool helps you identify the top 10 best-performing hybrids for different locations within your fields. By matching soil type with Answer Plot® test results, your WinField agronomist can provide you with the right seed product options — including photos of root appearance and anticipated ear size for each hybrid — that have the best chance of success under current conditions.

4. PLANT NUTRITION INSIGHTS
This season’s tissue testing data and analysis with the NutriSolutions 360™ system provides a road map for plant nutrition planning in the coming season. Tissue testing data provides you with insights of how to correct plant nutrient deficiencies throughout the growing season, so your crops are able to reach their optimal yield potential next season.

Capturing Maximum ROI

Research Team
Marker-assisted breeding technology has dramatically increased the speed of developing new hybrids with improved yields and stress tolerance. This novel breeding process involves testing a small chip removed from the seed coat and endosperm to select seeds with specific genes and traits, drastically shortening the development period.

The question is: Are you reaping the benefits of these new hybrids and varieties as soon as they become available?



"Over the last several years, we’ve seen up to 5- to 6-bushel-per-acre yield increases with many new hybrids as compared to the current elite hybrids," says Brad Miller, region product manager, WinField. "Farmers need to capitalize on these gains as soon as possible or they’re losing out on yield."

MANAGEMENT INSIGHTS ENABLE SUCCESS
A primary reason why you can confidently plant new genetics in a shorter period of time is the management information gleaned through the Answer Plot® program.

"Our Answer Plot® research includes numerous replicated trials for statistical accuracy and a high level of confidence in our data," Miller notes. "Through this research, we develop key insights about the right management practices, such as plant populations, soil types, plant nutrition and other factors that will help farmers capture maximum yield potential the first year they plant new products."

IDENTIFYING SUCCESS
"Farmers are going to have approximately the same cost per acre for seed, whether they’re buying products that came out this year or four years ago," Miller notes. "However, sticking with an older hybrid with less yield potential than new releases for several years could cost that farmer 15 to 20 bushels per acre in lost yield during that time.

"WinField agronomists have the tools to help you take advantage of new seed technology as soon as it’s available and capture maximum return on your seed investment,” he adds.

Optimize Spring Burndown Applications

Research Team


Spring burndown applications — common in no-till acres — can help you in the fight against weed resistance. Darrin Holder, regional agronomist, WinField, says this proactive approach is critical. “Once herbicide resistance takes root on a farm, in-crop opportunities for control are limited.”

Holder shares the following advice to help you optimize burndown applications this spring.

ASK THE RIGHT QUESTIONS
Effective weed control starts by asking the right questions. First, work with your agronomist to outline your crop rotation schedule and field history. List recurring weed problems and signs of herbicide resistance. Don’t limit your analysis to your acres; examine conditions in neighboring fields. If a neighbor is fighting resistance, it’s likely that seed will be in your fields soon.

THINK LONG TERM
Even a small patch of resistant weeds left unchecked one year can become a big problem the following season. “Develop a multi-year, multi-crop strategy,” advises Holder. “If you're battling resistant Palmer amaranth, it can be worth investing in a burndown treatment before this year’s corn crop to protect next year’s soybean crop.”

PRESCRIBE THE BEST TANK MIX
Herbicides with residual control extend burndown benefits, helping crops stay clean during critical stand establishment. “Even small weeds can rob emerging crops of valuable moisture and nutrients,” says Holder. “If you take away moisture and nutrients, you take away yield potential.”
