Site-specific controls for nematodes in cotton

By Peter Hull

Ahmad KhalilianA groundbreaking study is developing new technologies for site-specific detection and control of plant-parasitic nematodes in cotton.

Every year, about 10 percent of U.S. cotton production is lost to nematodes, causing losses of more than $300 million to the $6 billion crop. Yield losses in individual fields may reach 50 percent.

The multi-state, multi-disciplinary research, led by Clemson, is seeking either to lower the use of high-risk pesticides – such as carbamates and soil fumigants – or to optimize the use of nematicides in cotton crops in the southern U.S. Results likely will have lasting environmental benefits while reducing pesticide costs for growers.

Funded by a USDA grant, the research involves scientists from biosystems engineering; entomology, soils and plant sciences; the Edisto Research and Education Center; and the Cooperative Extension Service.
