The Ten Commandments of Weed Control

Soybean growers should adopt a full-season weed management program to stay ahead of tough-to-control and resistant weeds. Dean Grossnickle, agronomy service representative with Syngenta, encourages growers to obey the 10 commandments of weed control, as he learned them from Dr. Stevan Knezevic, professor of agronomy and horticulture at the University of Nebraska-Lincoln.

“Commandment number one, know your weeds and understand their lifecycle and biology. Rotate your crops, that’s number two. Rotate your herbicide sites of action. Use premixes with multiple sites of action, not looking at the name on the jug but understanding what’s in that jug, do we have something that has multiple active sites of action. Number five is use those full herbicide use rates. Number six, you got to scout your fields. Number seven, after your scouting, you need to apply that post emergence applications where necessary. Additionally, manage the weeds along your borders, where do we have the most pressure in a lot of our fields, it’s on the sides of our fields as they’re creeping in from the edges and on the end rows. Number nine, you always need to use cleaning equipment. And finally, number 10, you must make sure that you know the cost of poor weed control. It would be much more expensive if you spend less money, but don’t kill the weeds and then have to fight resistant weeds the next year.”

Grossnickle says its important that growers understand and use these commandments.

“I think it’s important growers understand this is because really, this is the key components to having sustainability of herbicide systems going forward. Syngenta established resistance fighter programs more than 15 years ago to help teach growers about the agronomic stewardship that’s vital in preserving herbicide technologies that we have. We know it takes a comprehensive strategy combining cultural chemical practices to be good stewards of the land and Syngenta, we’ve always thought that the only legacy worth having is one built on preserving that going forward.”

Dr. Knezevic shares what growers should expect if they don’t follow these commandments and allow weeds to survive in their soybean fields.

“Those big pigweeds are just laughing and smiling and they’re thriving. And they are surviving and producing seeds. So if they started doing that, I guarantee you within five years, we’re going to have a dicamba-resistant waterhemp.”

Tavium® Plus VaporGrip® Technology herbicide offers multiple effective sites of action, to help soybean growers follow these commandments.

“Making a valuable tool for managing tough to control broadleaf and grass weeds in soybeans, but like with all other herbicides for the best results growers need to use Tavium as a part of a sound weed management program. It really starts with full rates up front, a good pre program, then we’re going to follow that up with overlapping residuals, which you get and Tavium, and then a timely post emergence application with something like Tavium, that really gives you that nice sound program to help keep your field clean and maximize the benefits of your weed control program.”
