EPA approves registration of Nimitz nematicide

Nimitz, a non-fumigant nematicide produced by Adama, has received federal registration from EPA.

According to a company news release, the active ingredient in Nimitz has a mode of action that categorizes the product within a new chemical classification. The United States is the first country to receive a federal registration, with approved crop use on cucurbits, (including cucumbers, watermelons, cantaloupe and squash), and fruiting vegetables (tomatoes, peppers, okra and eggplants).

“Nimitz is the nematicide that growers have been waiting for,” said Herb Young, Adama brand leader. “It is highly effective in controlling plant-parasitic nematodes.

Nimitz eliminates stringent use requirements of fumigant nematicides including Fumigant Management Plans, re-entry intervals (REI), 24-hour field monitoring and restrictive buffer zones.

“In contrast to fumigant nematicides, Nimitz simplifies nematode management by lessening complex handling practices and application restrictions,” said Young. “Nimitz has no REI and does not require certified applicator training. Also, personal protective equipment (PPE) is minimal.”

“As the first new chemical nematicide to be developed in more than 20 years, Nimitz will fill an industry-wide demand for highly-effective nematode control as companies phase out older, more toxic and environmentally-hazardous nematicides,” said Pablo A. Navia, ADAMA innovation technical leader.

Cited by Navia as a “true” nematicide, Nimitz causes irreversible and rapid nematicidal activity immediately following an application. Within one hour of contact, nematodes cease feeding and quickly become paralyzed. Within 24 to 48 hours, pest mortality occurs rather than temporary nematostatic (immobilizing) activity, as seen with organophosphate and carbamate nematicides.
