Operation Weed Eradication: Adopting a Zero-Tolerance Approach to Pigweeds

Since the beginning of agriculture, the battle between weeds and farmers has been constant as weeds continue to adapt to management practices in order to survive. The struggle continues today with waterhemp and Palmer amaranth, two pigweed species that have become especially problematic for Illinois soybean farmers due to their inherently competitive characteristics and evolved resistance to several classes of herbicides. To curb this threat, farmers need to adopt an integrated, zero-tolerance approach to pigweed management, which is the goal of BASF’s Operation Weed Eradication. Before developing a plan for controlling waterhemp and Palmer amaranth, it’s important to understand [...]

What Your Waterhemp Hopes You Don’t Know

The 2021 planting season has begun in many counties across Illinois which means a new year is beginning for fresh thoughts and ideas. The first two weeks of April provided dry soils for planting, tillage, NH3 application and spring herbicide burndowns. However, recent rains have brought field activity to a strong stop. Now is a great time to reevaluate your herbicide program for the coming spring. Over the past five years, I have started taking a larger role in herbicide programs. I did this because there was an increasing number of producers asking if we had been successful on [...]

Do Not Lead with the Big Guns

Weed management is more than just selecting a post applied herbicide trait in your soybeans and waiting to spray when weeds emerge. Over the last 10 to 15 years, it seems like many producers aren’t sure if they will have a weed pressure problem and so are reluctant to get aggressive with a foundation effective herbicide. Instead, it’s become more of wait and see, then react with post herbicide. We apply nitrogen every year ahead of corn because we know a corn crop will need nitrogen. In fact, many producers have implemented strategies to maximize season-long supply by splitting [...]

What to do while we wait for the Elusive ‘Silver Bullet,’ Recap of Summit Breakout

During the Soybean Summit session on February 24, I had the opportunity to learn from Dr. Bernards  with the Western Illinois University School of Agriculture and his presentation of “What to do while we wait for the Elusive ‘Silver Bullet.’” If you were unable to attend this event, I would like to provide some insight on the topic. I hope after reading this blog you will be energized to follow the link to watch the full presentation: What to Do While We Wait for the Elusive “Silver Bullet” - YouTube Over time, there have been several major concepts or [...]

What and Where Is Your Weed Problem?

This time of year, growers are riding in combines and grain carts over thousands of acres, and it’s hard not to find areas of weed pressures that broke or even new green weeds starting to emerge. As you find those areas, it’s important to determine why there was weed pressure in the field and how to properly manage next year. It was Albert Einstein who said the definition of insanity is doing the same thing over and over and expecting a different outcome. Now is the time to recognize the issues, soon will be the time to learn about [...]

Begin Controlling Weeds Now for 2021 Soybean Acres

The sight of crop fields brightly adorned with blooming weeds in April and May is becoming an increasingly common occurrence in Illinois. While this is not a new observation for no-till fields, particularly in Southern Illinois, winter annual weeds are becoming increasingly common due to a trend toward reduced tillage as well as unpredictable fall and spring weather patterns that may delay planned tillage operations or herbicide applications. While winter annual weed species do not directly compete with the crop during winter months, there are several factors to consider that may make fall control of winter annuals a beneficial [...]

Herbicide Active Ingredients – A Deeper Dive

Herbicide active ingredients are the components of a formulation employing phytotoxicity on targeted weed species. Most herbicide labels list active ingredient and inert elements as a percentage by weight as well as pound of active ingredient per gallon or per pound for liquid and dry formulations, respectively. Referencing herbicide active ingredients for each product is a critical step for any weed management practitioner. This is important to assess and understand for several reasons such as: Validating the active ingredient is toxic to the desired weed species Reducing the overreliance on specific active ingredients (many of the same active ingredients [...]

Managing Resistant Weeds with Seed Destruction Technologies

This article was originally published on the Soybean Research & Information Network, a checkoff funded website. Controlling weeds like herbicide-resistant waterhemp and other pigweed species is a serious economic challenge for soybean farmers. Rather than wait until all herbicide options become unavailable, weed scientists are evaluating non-chemical control options now. “Postponing non-chemical weed control research until all available chemical control options have been exhausted would be a mistake and would leave producers with a lack of weed control options and even more serious herbicide-resistance issues than producers currently face,” says Kevin Bradley, University of Missouri Extension weed scientist. “That [...]

It’s Never too Late in the Fight Against Weeds

When Roundup Ready® soybeans were introduced, times were good. You could schedule your spray application from the calendar and not think twice about whether your fields were going to stay clean. Mother Nature has since prevailed, showing scientists who is boss and showing us what we’ve been taking for granted. In the perfect scenario you would see a weed-free field with an ideal spring, but that’s not so common anymore. We now must take extra time and effort to find that right weed control program. Waterhemp escapes in a soybean field. Photo courtesy of University of Illinois. There is [...]

Managing Weeds Before They Become a Problem

The saying “It’s better to be proactive instead of reactive.” holds a lot of weight for soybean growers when it comes to managing weeds in a burndown. There are a lot of no-till fields in the state of Illinois, therefore these fields need to be managed differently than a conventionally tilled field. In many fields across Illinois, glyphosate-resistant marestail has increasingly become a challenge to manage. In today’s modern climate, there are new Group 4 growth regulator, trait tolerant soybeans in the market for planting 2020. But should a grower solely rely on a post-emergence solution?
