Peanut producers may not see a $700 per ton contract but they stand to gain $150 or more from the subsequent cotton crop because of rotation. “We get a good yield bump from a peanut rotation,” he said. “A 200-pound-per-acre increase in cotton yield, even at 50 cents a pound, will get the peanut revenue closer to where it needs to be.”

And 200 pounds at current prices adds even more to the two-crop system.

Even on the Caprock, growers should get as much information as possible on potential rotation crops to determine the effect on later cotton planting. “Some crops can make nematode populations worse.”

A peanut and cotton rotation demands close watch on weed control.

“Some weeds can serve as hosts to nematodes, allowing for reproduction, potentially negating the benefit of the rotation,” Woodward says.

Losing Temik, he says, will increase the need to rotate. “We don’t use a lot of Temik in Texas on peanuts because most of our peanuts are grown where we don’t have the peanut nematode. Some areas in Texas have heavier infestations, however.”

He said the issues that will evolve with losing Temik are coming “sooner than we think. Don’t forget the value of rotation.”
