Korea Protocol

At the latest bilateral meetings between USDA, APHIS and Korea QIA, it was agreed to continue under the 2010 Plant Quarantine Agreement, which means the requirements for exporting to Korea are the same as last season. To preserve access to this critical market it is incumbent upon each grower, shipper, and the industry as a whole to show progress in reducing detections of Fuller rose beetle and California red scale. QIA had made it clear that they want mitigation measures other than methyl bromide fumigation in place in the near future.

To meet the requirements for Korea, growers should follow the long established Septoria Guidelines by making the recommended fungicide treatments, implement effective California red scale control, and follow the Fuller rose beetle UC IPM Guidelines.

The provisions for meeting Fuller rose beetle requirements include:

  • Skirt pruning to prevent skirts from contacting the ground
  • Weed control sufficient to prevent forming a bridge from the ground to tree skirt
  • Two treatments in accordance with the UC Integrated Pest Management (IPM) Program guidelines

Dr. Beth Grafton-Cardwell has stated that research from 2013-2014 demonstrates that two insecticide treatments per season are better than one. These treatments could be ground treatments of Brigade or a combination of several foliar choices. The ground treatment helps to keep emerging beetles from climbing the trunks and the foliar treatment kills them if they do reach the foliage. If two foliar treatments are planned, early August and early October are the best time periods for the San Joaquin Valley.

Choice of insecticide depends on application target and concerns about MRLs. Skirt pruning in June and weed control are essential components of the Fuller rose beetle program. Korea may allow blanket fumigation or fumigation of infested loads with Methyl Bromide this year, but they are counting on California growers to apply in-field treatments to lower FRB populations. Methyl Bromide is not likely to be allowed in future years. Treating for FRB several years in a row with foliar and/or ground treatments will help to bring the populations down.
