Zone application of Telone producing economic cotton yield returns

There’s no doubt that $50 an acre is a high price to pay for one input, especially if you’re not sure the input will provide an increase in your cotton yields, says Tom Allen, Extension plant pathologist with the Delta Research and Extension Center, Stoneville, Miss.

That’s why growers need to combine applications of Telone II, a soil fumigant that has shown success in controlling nematodes, with site-specific management practices to make sure the Telone gets to areas where it will do the most good.

“You need to put a probe in the ground and determine what your nematode numbers are,” says Mississippi State University’s Allen. “That will be the most effective way to look at those EC management zones and how the application of something like Telone is going to reduce your nematode numbers.”

Allen spoke on site specific nematode management with Telone II in the Mississippi cotton production system at the National Conservation Systems Cotton and Rice Conference in Tunica, Miss.

Applying Telone is not that difficult a practice, according to Allen, who demonstrated how he uses a four-row system equipped with coulters that places the liquid up to 16 inches in the ground. The liquid then vaporizes and kills the nematodes.

Mississippi State researchers have observed yield increases as high as 150 pounds of lint cotton per acre when the Telone reduces nematode populations below threshold levels.
