When a Plan Comes Together

Farmers around the world are challenged by many natural causes and one major factor being weeds. This calls for an integrated approach combining diverse weed control tactics.

Farming has always been in my blood – and in my roots. I really feel blessed to be a fourth-generation farm land owner and to cultivate the property my great grandfather homesteaded in 1910. Ever since I can think, there has been nothing more rewarding than watching a field plan come together. Sweeping the combine through the field to look back on a full truck of grain and pulling in a bumper crop is just what I live for.

Knowing that our family farm was instrumental in utilizing the advancements in agriculture to increase productivity and meet the demands of the first Green Revolution is a great motivation for me. It’s the fuel that constantly drives me to carry on this tradition. I have complete confidence that science and tech breakthroughs will be essential in helping to provide a growing world population with safe and nutritious food now and for future generations.

Weed challenges – we’re all sitting in the same tractor

 I have to admit that while growing up on my family farm weed control operation was never a cool or fun job. Let’s say, it was a necessary evil. Weed control was very weather-dependent. In less than two weeks you could go from optimal weed size for spraying to off-label recommendations that cost a lot of money and time to manage. Four decades later, the same hurdles are still echoed by growers. Clearly, it was time to rethink our approach to weed control. As fate would have it, I’m presently responsible for the management and implementation of Bayer’s Integrated Weed Management program in the U.S. and Chair of the U.S. Herbicide Resistance Action Committee. I have the coolest job ever! I coordinate waging a war against herbicide-resistant weeds. On my side: world-renowned scientists. Together, we develop new innovations and techniques that can keep the modern-day farm competitive and sustainable. 

A low weed seed bank means fewer weeds and more yields.

For me, there is nothing more gratifying than to be able to share my insights and help growers to manage their weeds in an efficient and sustainable manner. The talk is of bringing the weed seed bank down. Let’s look at how this is possible, simply by considering three priorities:

1. Make a weed seed bank plan

The first thing I have learned from this group of experts reminds me a lot of my retirement plan: Start by investing in a diversified portfolio that will pay dividends in the future. What we need to do is move from talking about weed control in season to thinking about a long-term plan that will drive weed seed banks low one year at a time.

2. Implement crop rotation

Crop and herbicide-tolerant trait rotations, where applicable, have many soil health benefits. These include driving the weed seed bank numbers down through crop competiveness and enabling multi-effective herbicide modes of action to be used.

3. Tank-mix multiple effective modes of action

For decades, we have been told that rotating modes of action is the best management practice to follow. Only recently have scientists provided research results that prove otherwise: utilizing a tank-mix combination of two different modes of action is 83 times less likely to develop resistance. So mix it up and utilize two effective modes of action.

It pays off to lower your weed seed bank

We have to rethink the way we battle weeds. One tactic is just not enough. Rather, an integrated approach which combines diverse weed control tactics is quintessential to stay ahead and keep your weed seed bank low. This way, you can preserve the value of your land, reduce your weed control costs and optimize your yields sustainably. Learn how it pays off to bring down your weed seed bank right here.
