For many years now, aldicarb or Temik has been the backbone of root-knot nematode management in Georgia for both peanuts and cotton, but it’s time to consider a new strategy, says Bob Kemerait, University of Georgia Extension plant pathologist.

“It was reported by Bayer CropScience they would phase out the production of Temik by 2014, and I was telling everyone not to worry about it, that we’d figure it out,” says Kemerait.

“But we all got a rude awakening in February of last year when we learned that due to litigation, Bayer decided it was no longer worthwhile to continue producing Temik, so that left us scrambling.”

Temik is still available, he says, but you’ll pay for it.

 (The loss of Temik already had altered some cropping plans last year. To see how some growers responded, click here).

“The first thing we use Temik for in peanuts is thrips control, and replacing it won’t be a problem there,” he says.

“We have Thimet, phorate and Orthene available, and Syngenta has Cruiser-treated peanut seed available this year for fighting thrips. Based on my limited research, I can’t tell you how effective Cruiser-treated seed will be against thrips as compared to Temik.

“My peanut trials with Cruiser-treated seed were planted late last season and there wasn’t much pressure from thrips. However, the product looked good under light pressure.

“I have heard estimates there might be enough Cruiser-treated seed this year for 60,000 acres. Just know that your opportunity to manage thrips has not changed with the loss of Temik — there are great options.”

More importantly, asks Kemerait, what do growers do without Temik this year for managing nematodes in peanuts?

“If you have difficult nematode situations as we do in southwest Georgia, and you’ve grown accustomed to using 10 pounds per acre of Temik at planting plus 10 pounds of Temik at pegging time or, even better, fumigating with Telone II and using Temik, then you’re deploying our best treatments to fight the nematodes.
