Corn Rootworm Control

Yield Loss Across the Corn Belt

Farmers across the country are witnessing corn rootworm overrun the current Bt-RW traits. Rootworm resistance to traited corn will continue to cost you valuable yield - and next year will be worse as the resistance spreads across your farm.

Your current options are costly and can greatly increase complexity during planting.

We can help.

Fight Back Against Resistance

At Persistent BioControl, we produce insect attacking nematodes that kill corn rootworm before they can damage your corn.

Our nematodes are microscopic worms that live in the soil. Just one application will protect your failing Bt-RW traited corn for multiple growing seasons.

Our product can be applied through any center pivot or spray rig - no special equipment required. And you can apply anytime the soil temperature is above 50F.

Explore the Science.
“After seeing the impact on my farm, I’m convinced it works. I’ll treat as many of my 7,000 acres as I can next year. I also run a custom harvest business, and I’m going to spread the word. You’ve got a great product.”

An Affordable, Long-Term Solution

Pricing starts at $70 / acre for our Corn Rootworm formula.  Discounts are available for large orders.

Since our nematodes are persistent, this is one-time expense that will pay dividends for years to come.

Learn more about pricing.

Application is Simple.

For fields with center pivot irrigation, our nematodes can be injected straight into the irrigation water.

Alternately, any ground spray rig can be used for application. To prepare the sprayer, flush the tank and all lines, then remove all screens and filters.

Invest in Your Farm’s Profitability

Using a 130-acre irrigated corn field as an example demonstrates an annual increase of $7,800.  Subtract the cost of PBC nematodes , and over the next decade, you’ll generate an extra $70,200 from your pivot!  And that’s just from the recovered yield.

You’ll also save money because you won’t need to apply soil insecticide over your failing traited corn or modify your corn planter to apply it. And you can keep buying your current seed - saving you from the extra cost of new traits and the yield drag that comes with it.

Let's get started.
“We recognize that long-term, the effectiveness of chemicals against rootworm will significantly diminish, so nematodes are an important way we can improve our effectiveness and enhance our sustainability.”
