Temik loss: resistance in cotton

Nematode-resistant cotton may be the best option but currently less than a handful of varieties with only moderate resistance are available. Putting resistance into a variety with the yield and quality traits growers demand will not be easy.

Cotton farmers and the agencies and industries that support them have three to four years to come up with new products, techniques or a combination of currently available strategies to manage nematodes before they lose Temik, a mainstay for crop protection for some 40 years.

Resistant cultivars may be the best option but currently less than a handful of varieties with only moderate resistance are available and putting resistance into a variety with the yield and quality traits growers demand will not be easy.

In the meantime, those varieties moderately resistant to root knot nematodes may be a better option than some believe.

“They may be more beneficial than some folks have given them credit for,” said USDA-ARS nematologist Richard Davis, Tifton, Ga., during a panel discussion at the recent Beltwide Cotton Conferences in Atlanta.
