Weeds
While all weeds are problematic, waterhemp, marestail, palmer amaranth, giant ragweed and Italian ryegrass are among the worst because they have documented cases of resistance to multiple herbicide groups, which makes them more difficult to control. In addition to resistance, they have the natural ability to evade herbicide control methods.
Doctors don’t prescribe treatment without first diagnosing the ailment. Weed control should work the same way.
Getting rid of yield-robbers takes careful planning and multiple modes of action
Waterhemp, marestail, palmer amaranth, giant ragweed and Italian ryegrass have been found guilty. Their crime: stealing nutrients, sunlight and water from your crops, leading to lower yields and profits.
Stay one step ahead of mounting resistance issues by knowing how to identify and control
Use products with different sites of action to prevent resistance from cornering your fields.
Move over waterhemp, ragweed, lambsquarters and all your weedy friends. There’s a new rabble-rouser in cornfields this season: volunteer soybeans.
The next generation of weed scientists battle it out in the field.
In addition to tillage and herbicides, other basic practices can help farmers manage weed seeds.
