How to maximize the efficacy of your crop protection products

For starters, ensure you have adequate water quality

Applying fungicide from the air

If an aerial applicator is applying your fungicide, consider timing and water volume

Dr. Tom Wolf, researcher and owner of Agrimetrix Research and Training, says aerial applicators are “tremendously important.” “They apply spray under conditions that a ground rig can’t — for example, with soil moisture. They cover much more area than a ground rig ever can so they can be more timely. ”Jill Lane, executive director of […] Read more

blackleg infection on a canola stem

Does it pay to spray fungicide for blackleg?

When you’re looking to guard your canola against blackleg, does it pay to spray a fungicide? The short answer is yes — especially if you’re running a tight canola-wheat rotation.

Herbicide-resistant weeds changing farm practices

Resistant weeds are driving U.S. farmers to actions like manual weeding

Arkansas has been ground zero for herbicide-resistant weeds. For instance, the state is second only to Australia in the amount of herbicide-resistant ryegrass in wheat. “We’re actually running out of herbicides, making it difficult for us to even grow wheat in Arkansas, because of the levels of resistance that we have,” said Dr. Bob Scott.
