An Invisible and Invasive Threat

Growers are underestimating the damage they can do — and their risk.

The Dirt on Nematodes

Nematodes are stealing corn, soybean and cotton yields - and getting away with it. 

In fact, nematodes cost an estimated 10.2% yield loss in corn, 10.6% in soybeans and 10.7% in cotton*.

Nematodes infect the roots of the plant, taking away its nutrients and water from the inside. Yet, despite how abundant they are, most nematodes are undetectable by the human eye. 

Nematodes can cause damage by:

    • feeding on plant roots;
    • facilitating bacterial and fungal infections;
    • and transmitting viruses.

Unwelcome Guests

Common management practices, including crop rotation, don't provide comprehensive control.

Once nematodes are in your fields, they can be difficult to get rid of. But how do they get into your fields in the first place? Anything that moves soil, moves nematodes. Shovels, boots, farm machinery… Even the wind can transport these microscopic pests.

Some nematodes can feed on different crops. Even though soybeans might be a preferred host, certain species can also thrive in corn.*

Hiding in Healthy-Looking Crops

Nematodes are found in corn, soybean and cotton fields — in all soil types — across the United States.

An Underestimated Problem

No Above-Ground Symptoms

Often, the damage plant-parasitic nematodes cause isn’t extensive enough to present any above-ground symptoms. But any damage to a plant’s root structure can be yield-inhibiting.

Damage Misattribution

When signs of damage do show up above-ground, they’re often mistaken as drought, malnutrition or disease. Typical symptoms of a nematode infestation can include wilting, yellowing and stunting.

Limited Awareness

Soybean and cotton growers are no strangers to nematodes. But their presence in corn — and their impact on the yields of all three crops — is underestimated by most growers. 

Need for Species ID

Because there are so many species, it has been difficult for growers to get management recommendations without knowing exactly what types of plant-parasitic nematodes have invaded their fields.

A Broad-Spectrum Seed Treatment Technology Is Here

NemaStrike™ Technology, a seed treatment technology that provides broad-spectrum nematode control for corn, soybeans and cotton.

With a novel mode of action and low water solubility, NemaStrike Technology defends crops from the start and stays in the root zone as plants grow — for up to 75 days. Plus, it has demonstrated consistent yield protection in hundreds of field trials, over 3 years of testing, in all soil types and levels of pressure.
