Adama announced that its Nimitz nematicide received state registration in California for use on tomatoes, peppers, okra, eggplant, cucumbers, watermelons, cantaloupe and squash.


The company says Nimitz is the first new chemical nematicide to be introduced in more than 20 years. The product’s label carries the least restrictive signal word – ‘Caution’.

In contrast to fumigant nematicides, the product simplifies complex handling practices and application restrictions. The result is no Fumigant Management Plans, no 24-hour field monitoring, no buffer zones, no re-entry interval (REI), no specialized equipment and minimal personal protective equipment (PPE).

“Nimitz is a contact nematicide, not a fumigant,” says Herb Young, Adama brand leader. “And because of its residual activity, Nimitiz’s control of nematodes often exceeds the commercial standards. The distinct advantage over other nematicides is that it frees growers from complications, liabilities, and dangers associated with fumigants.”
As a non-gas formulation, the active ingredient in Nimitz is distributed through the soil and into contact with nematodes through irrigation or rainfall. Unlike older chemistries, there is no mandatory tarping or specialized machinery requirement. Applications may include broadcast or banding with mechanical incorporation or through drip-injection.

The procuct causes irreversible nematicidal activity which results in pest mortality within 48 hours of application, rather than temporary nematostatic (immobilizing) activity as seen with organophosphates and carbamate nematicides.

“NMITZ is lethal to nematodes. As a result, we see greatly improved root health all season which leads to yield enhancement,” says Young.

The EPA wrote in the Federal Docket on July 24, 2014 that, “Fluensulfone (Nimitz) represents a safer alternative for nematode control with a new mode of action and a much simpler and straightforward product label.”

A secondary crop tier has been submitted to the EPA for future registration on potatoes, strawberries, carrots, tobacco and turf.
