Increase Profits, Protect Corn Yield

At Persistent BioControl™, we produce biocontrol nematodes that attack, kill, and multiply inside Western Corn Rootworm larvae before they can damage your corn yield. 
In corn, a 5% yield loss has no visible sign above ground but costs you $65 per acre.  You could be losing this yield without realizing it.
A single application of our nematodes will protect your failing traited corn against this yield loss, pay for itself in a single year, and fight Corn Rootworm resistance for multiple growing seasons.
The corn roots pictured here are from neighboring fields where our biocontrol nematodes were applied six years ago!

What makes our biocontrol nematodes unique?


Persistent BioControl™ nematodes can be applied at a much lower rate because they multiply in the corn rootworm larvae and persist into the next growing season. (Other commercial nematodes must be applied at very high rates in order to be effective, making them very expensive).

Years of Protection

Persistent BioControl™ nematodes will persist in your field for multiple growing seasons after a single application. (Other commercial strains require an application each year and last less than a month)

Apply anytime

Persistent BioControl™ nematodes have a wide application window because they have the wild genetics to persist for long periods of time. (In contrast, other commercial strains survive for less than 30 days, making application timing critical to their effectiveness)

Real World Results - A Case Study

126 acres

in Roswell, NM were treated with persistent nematodes in 2019.  The previous year, Bt resistant CRW had overrun the Bt-CRW traited corn, causing a 38% reduction in silage yield.

+ 44 % yield

In 2019, the same year persistent nematodes were applied, silage yield made a full recovery to 2017 levels.  The same Bt-CRW traited corn variety was used each year.

+$ 55000

in incremental profit was produced in 2019 from this 126 acre center pivot.  The 2019 application of persistent nematodes continued to fight CRW resistance and deliver increased profitability in 2020, 2021, and 2022. 

Fortify your Bt-CRW traited corn

Compatible with all pest mitigation programs

Persistent BioControl™ nematodes kill CRW larvae before they can eat corn roots and cause yield loss.  They are compatible with all CRW management programs, traited corn varieties, soil insecticides, and soil types. 

Increase Profitability

Our nematodes are meant to supplement the effectiveness of your traited corn variety by eliminating partially resistant survivors.  Not only does that prevent incremental yield loss, but it fights CRW resistance and helps extend the useful life of your traited corn.  That means you won't need to switch to the new, more expensive traited variety, saving you money.

Backed by 25+ years of research
Persistent BioControl™ nematodes are backed by 25+ years of university research and have been successfully applied in 17 states including Nebraska, Colorado, Iowa, Wisconsin, Texas, New Mexico, and New York.
Our biocontrol nematodes have never failed to establish in any field where they’ve been applied and the original test plots are still showing persistence over 20 years later!
In fact, we are so confident that they will persist in your field that we will reapply them for free if we can't detect them the following year.

I want to place an order. What happens next?

1. Contact Persistent BioControl™ using the contact form here or email and let us know you are interested in an application.  We can setup a phone call to answer any questions you have and to learn more about your specific application.
2. Once you place an order with us, we will begin growing your nematodes four weeks prior to the application date.
3. After your nematodes are grown, they are washed into a solution at our facility and are delivered in liquid form.
4. Payment is due on delivery.  We then remain onsite to assist you with application; either using your spray rig or through center pivot injection.
