Works Fast

Aproach® Prima fungicide provides uptake in plants that is nearly twice as fast as competitors, thanks to the active ingredient picoxystrobin. Its varying movement properties quickly surround and penetrate each leaf and stem, providing systemic protection. Aproach Prima is rainfast within one hour and residual for up to three weeks.

Preventative and Curative

Aproach® Prima fungicide provides two modes of action: It is both preventative and curative. This allows for a greater application window. Aproach Prima is tough against fungicide-resistant diseases such as frogeye leaf spot, thanks to its second active ingredient: cyproconazole.

Better Bottom Line

Aproach® Prima fungicide is shown to improve crop quality and increase yield, meaning a greater return on investment. It’s registered by the U.S. Environmental Protection Agency for use in multiple crops, meaning one simple choice for growers with many crops to protect.

Aproach Prima – Stop the Clock on Crop Disease

Watch video

The impact of fungal disease on crop yields can be significant. As humidity increases during the summer months, so does the development of fungal diseases. The longer you wait to take action, the more disease will spread and your crop will take the hit. Applying DuPont Aproach Prima fungicide can put a stop to disease progression and stop the clock on your yield loss.

Simple to Use

“Aproach Prima is a very simple product for us to use. It keeps our efficiency up. I like the way it works systemically in the plant, in the leaf. So, we don’t have to use the spreading agents that a lot of the other products require. It’s a lower use rate so we can cover more acres.”

Kevin Stansberry, Stansberry Agriculture Services, Ryan, IA

More Bushels, More Dollars

“Aproach Prima is worth it from the standpoint that the yield increase is going to give you something no other chemistry combination is going to give you. It’s a way to put more bushels, more dollars in a farmer’s pocket.”

Longer-Lasting Effect

“In the past I’ve used generic products and I came to the realization that if I was going to spend the money, it was going to have to be for a fungicide that has curative effects, along with a longer-lasting effect. That is why I’ve used Aproach Prima the last couple of years.”

 - Doug Meyer, Farmer, Lincoln, NE
