Nimitz Nematicide Receives Registration In California

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


The nematicide, which received EPA approval in September 2014, controls plant-parasitic nematodes on commercial vegetables and features a fast-acting and unique mode of action.

Nimitz is the first chemical nematicide to be introduced in more than 20 years, and simplifies nematode management by lessening complex handling practices and application restrictions, according to the company. As a result, growers do not have to develop fumigant management plans, and do not have to monitor their fields for 24 hours. Furthermore, there are no buffer zones, no re-entry interval, no specialized equipment needed, and minimal personal protective equipment.

“Nimitz is a contact nematicide, not a fumigant,” says Herb Young, Adama brand leader. “And because of its residual activity, Nimitz’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.”

An Improved Solution
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 other chemistries, there is no mandatory tarping or specialized machinery requirement. Applications may include broadcast or banding with mechanical incorporation or through drip injection.

Nimitz is said to cause 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.

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

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.
