The tuberworm has been recorded in California since 1856, and several times in the last 20 years it was found in the Columbia Basin of Oregon and Washington. However, it was not a major concern for growers in the Pacific Northwest until 2002, when a field with severe potato tuberworm damage was documented in Oregon. The pest is difficult to control and over the years, many farmers have relied extensively on the use of insecticides to control it.

Tuberworm is just one of many pests described in the updated IPM manual by the University of California Statewide IPM Program. Growers can find information on diagnosis and treatment for more than 120 potato pests and disordersóranging from black scurf, which causes superficial damage, to late blight, which can destroy a whole crop. The guide includes 51 new color photos (bringing the total to 210), 58 tables and line drawings, a section on organic potato production, and a comprehensive index.

Protecting potatoes from insect infestations and diseases is essential to the production of a high-quality crop. The manual contains a new section on general predators and extensively revised sections on aphid management and virus transmission, leafhoppers and phytoplasma transmission, late blight, bacterial early dying, necrotic strains of Potato Virus Y, black dot, silver scurf, and using cover crops for nematode management. Included in the new edition are information on testing Colorado potato beetle populations for insecticide resistance, and a detailed discussion of differential host tests for identifying root knot nematode species and races.

Forty university researchers and Cooperative Extension specialists from across the West contributed to making this revision an up-to-date and essential reference for potato growers and pest management professionals.

More information on the potato tuberworm is also available on the UC Statewide IPM Programís Web site. Look under "potatoes."
