Cereal leaf beetle regulations
Introduction
Cereal leaf beetle (CLB), Oulema melanopus, is a destructive pest of cultivated grasses, including barley, oats, rye, and wheat. Hosts of CLB also include corn, sorghum, and various ornamental and wild grasses. The pest was introduced into the United States in 1962 from Europe, where it was first discovered in an oat field in Berrien County, Michigan. It has since spread to many locations in the United States. CLB was first discovered in Oregon in 1999 and has since been found in nineteen counties including Baker, Benton, Clackamas, Columbia, Crook, Deschutes, Jefferson, Lane, Linn, Malheur, Marion, Multnomah, Polk, Tillamook, Umatilla, Union Wallowa, Washington, and Yamhill.

Regulations
With the introduction of Oulema melanopus, the California Department of Agriculture added Oregon to the Cereal Leaf Beetle State Exterior Quarantine. Commodities covered in the quarantine include small grains (barley, oats, and wheat), corn, straw, and hay (including marsh hay), grass, forage seed, fodder, plant litter, Scotch pine, red pine, and Austrian pine.
Oregon nurseries are prohibited to export commodities listed in the quarantine with the following exceptions; commodities from an infested county, certified as treated by a state agricultural official or commodities from an non-infested county, certificate of origin inspection by a state agriculture official. The California Department of Agriculture also has issued a CLB master’s permit, Permit Number QC 1001, allowing the shipment of Scotch, red, and Australian pine seedlings that meet the following conditions:
  • Only Austrian, red, and Scotch pine that meet all the requirements can be shipped to California.
  • All Pinus sp. material produced within the state of Oregon.
  • All Austrian, red, and Scotch pine must be caliper size of one inch or less measured at soil line and shall not be commingled in the shipment with like pines from other origins.
  • The Oregon Department of Agriculture (ODA) shall monitor the shippers to ensure that the conditions of permit are met.
  • The shipper shall keep records of the quantities of each type of Austrian, red, and Scotch pine shipped to each receiver in California.
  • Each shipment into California shall be accompanied by a certificate issued by an authorized representative of ODA affirming that the shipment meets the requirements of California permit number QC 1001.
