The Environmental Protection Agency has registered Nimitz nematicide from Raleigh, N.C.-based Adama for use on fruiting vegetables, including okra, and cucurbits.

State registrations are pending.

Nimitz, which contains the active ingredient, fluensulfone, differs from most other registered nematicides in that it is not a fumigant, says Herb Young, brand leader.

“It's a contact nematicide moved by water, so it's a completely different concept than fumigation,” he says. “You have to take the Nimitz to the nematode – that's the new concept that growers need to think about. What water regime can I use to take the Nimitz to the nematode?”

As a result, the nematicide carries significantly fewer application restrictions than traditional fumigants.

In fact, the label carries only the signal word “caution.”

No buffers are required nor do users have to draft a fumigation plan before using it. Users also don't need to tarp the ground as part of application, and there is no worker re-entry interval.

The product is labeled for preplant treatments and can be used alone or as part of an integrated program, Young says.

“We're not claiming to replace the weed part or the disease part,” he says. “We're going after the nematodes.”

It can be applied as a broadcast, as a band or through drip irrigation once fields are bedded up. Growers must wait at least seven days after application before transplanting.

Water application will be critical to the product's efficacy and will vary, depending on soil type and crop, Young says.

Adama plans to conduct training and certification for distributors and anybody else who will be recommending Nimitz so they'll understand the water requirements and different application techniques, he says.

But growers won't need to undergo certification or training to apply it, Young says.
