Setting the Trap:Trap crop control of the pale cyst nematode, Globodera pallida

摘要

Insidious and invasive, potato cyst nematodes top the list of economically devastating nematodes for potato production. Internationally recognized quarantine pests, Globodera rostochiensis and Globodera pallida can cause extensive damage and, if leftuncontrolled, can reduce yield by 80 percent. Although not widely distributed, both are present in the United States. The golden nematode, G. rostochiensis, first discovered in New York, has been contained to 5,945 acres in eight counties in New York. The pale cyst nematode (PCN), G. pallida, infests 3,277 acres in portions of two counties in Idaho. Spread mainly through soil contaminated with cysts, adherence to a stringent phytosanitary programs by USDA-APHIS and respective state agencies (NYSDA and ISDA) has prevented spread of cysts to other potato-growing areas; PCN remains contained to less than 1 percent of the total acreage planted to potato in Idaho.
