It doesn’t look like the much-promised Temik replacement and aldicarb product Meymik will make it into the market place in time for use in 2013.

Whether or not Meymik, or any meaningful aldicarb product will ever make it to the market is far from certain.

The company, More Economic Yield, or MEY Corporation, isn’t talking about the future of Meymik, other than to say construction of a production facility in Georgia has been delayed.

Causes for the delay vary from source to source, but the bottom line is no Temik-like product for 2013.

Without Temik more and more growers are depending on seed treatments to manage thrips. The most popular of these treatments contain imidacloprid, deemed by some to be the most widely used insecticide in the world.

Imidacloprid is a neonicotinoid, which acts on the central nervous system of insects. Technically, it blocks the nicotinergic neuronal pathway, which less technically kills the insect.

Because it binds much more readily to insects than mammal neuron receptors, imidacloprids are relatively safe for humans to use — another big plus to being the most often used insecticide in the world.

This family of insecticides has been around a long time and many generic products containing imidacloprid are available and used as seed treatments for thrips. These insecticides do work, but they just won’t hold up season long under heavy thrips pressure, Bacheler says.

Danny Pierce is a long-time North Carolina Crop Consultant, with more than 30 years in the business. He may just be the dean of licensed crop consultants in the state. He says, he has long questioned the rates of imidacloprids used in seed treatments.

Two years ago Pierce began doing some private testing on higher rates of imidacloprid and made his own seed treatments, with some outstanding results.

Since this treatment is off label, Pierce took his findings to Bacheler, who included them as part of his thrips management research program.

Bacheler looked at Pierce’s results and began testing high rates of the material used as a seed treatment.

“At first look, it didn’t look all that great,” he says. “But after we picked the cotton and processed the data, a 6X treatment of imidacloprid did well. In other tests a 10X rate looked good on cotton, even in areas with fairly high thrips populations,” Bacheler adds.

Working with North Carolina State Ag Extension Agent Norm Harrell in Wilson County, N.C., Bacheler says they came up with some interesting results that may help growers with thrips management next year.
