ITHACA -- Cornell Cooperative Extension agents are educating growers across the state about the use of native nematode worms to control destructive alfalfa snout beetles.
Cornell scientists say 500,000 acres of farmland in nine counties have been infested by the beetles, which can destroy entire fields in one growing season. Crop damage can cost as much as $1,500 an acre.
In addition to teaching farmers how to grow and apply nematodes that kill the beetles, Cornell is creating alfalfa varieties that are resistant to the insects.
Cornell entomologists are now evaluating the use of nematodes to control pests in New York's grape vineyards and apple orchards.
