Potato Insect Monitoring Report: May 2–8, 2012

This weekly report provides the potato industry with current information about the size and whereabouts of important insect pest populations in the Columbia Basin. The project targets three key insect pests: green peach aphid, beet leafhopper, and potato tuberworm. Read the full report.

Zebra Chip

Zebra Chip, a disease seriously impacting potatoes produced in Texas and other Southwest states in recent years, has been found impacting potatoes in the southern Columbia Basin in 2011. See the message from Phil Hamm, Oregon State University, to the Washington Potato Growers and allied industries: Phil Hamm’s message to industry. Included here are informational items about this disease and its vector. Please contact Andy Jensen, 509-765-8845 or Phil Hamm Phillip.B.Hamm@oregonstate.edu with questions.

Vegetable Resource Highlights

• Grafting in Vegetable Production. Vegetable grafting is relatively new to the U.S. but is quickly gaining use, especially in greenhouse tomato production. Learn about vegetable grafting from these Extension publications and presentations.
• Biology and Management of Aphids in Organic Cucurbit Production Systems. This article by Mary Barbercheck, Penn State University, provides an overview of the biology and life cycles, damage from, and management of the most common aphid pests in organic cucurbit crops.
• Weed Management Strategies for Organic Cucurbit Crops in the Southern United States. Mark Schonbeck, Virginia Association for Biological Farming describes how to manage some of the most troublesome weeds of cucurbit crops in the South.
• MSU’s Research results for bacterial canker in tomatoes. Research indicates it is best to manage canker before field planting tomatoes.
• Bacterial canker ravages processing tomatoes. Learn how to recognize bacterial canker now to manage this disease in the future.
