Studies also show that Temik performs better than seed treatments for the suppression of aphids in cotton, according to Lorenz.

With the loss of Temik, “we just have to live with that situation and realize that these seed treatments are not going to help us out with these secondary pests.”

Lorenz says the loss of Temik not only deprives growers of a viable product, but it places more emphasis on the neonicotinoid class of chemistry used in many seed treatments. “There are not a lot of other products to depend on if we get into a serious situation. We’re depending on the industry to bring forward some new chemistry to help us out.”

University of Arkansas Extension plant pathologist Scott Monfort says Temik’s biggest benefit for cotton producers has been control of nematodes in moderate to severe infestations. “One reason Temik will be missed is because it has such a broad-spectrum. It’s helped us in a lot of different areas. It is the golden standard when we talk about nematode control.”

A study comparing seed treatments versus Temik in severely infested fields showed that Temik almost doubled yield versus an untreated check, while a seed treatment increased yield by almost 50 percent over the untreated. “In most moderate to severe situations, we’re going to have to combine some products. We can’t go at it with seed treatments alone. You’re not going to get the control you need.”

Producers can still use precision farming technology for site-specific applications of Telone for nematode control, according to Monfort. Studies have shown savings in Telone applications of 36 percent to 41 percent through site-specific techniques.

Monfort advises producers to not forget other problems in the field when implementing control measures for nematodes. “If you don’t correct your fertility or seedling disease problem, or if you don’t have a good idea of what nematodes will do behind corn or grain sorghum, or if you don’t fix your soil compaction problem, you can’t maximize the nematode control benefit. It all needs to come together as a system.”

For example, tests on the impact of tillage on nematodes showed yields of 750 pounds on untreated, un-ripped plots, 950 pounds with Telone, unripped plots, and 1,000 pounds with Telone, ripped plots. “If you don’t put out Telone and you still rip, it’s quite a bit better than un-ripped and untreated plots. Take care of all the problems,” Monfort said. “We don’t work in a vacuum.”
