Bio: Bill Krueger serves as a Glenn County Farm Advisor, with a specialty in olives and Integrated Pest Management. At Washington State University he earned his Bachelor of Science and his Masters of Science degrees in Horticulture. Bill worked worked as an orchard foreman in White Salmon, Washington before coming to the University of California Cooperative Extension in Glenn County, where, since 1980, he has served as the Horticulture Farm Advisor. Working in all phases of crop production for almonds, prunes, walnuts and olives, Bill has conducted long term research in hedgerow plantings of these crops. Integrated Pest management has been an important part of his program, and Bill is currently involved with cooperative research looking for safer, less disruptive methods of pest and disease control in prunes, almonds and walnuts. The author and co-author of more than 50 papers and publications, Bill's vast knowledge and expertise make him a valuable asset to the northern California area.

Guthion-resistant walnut aphid parasite: Release, dispersal, and recovery in orchards Guthion-resistant walnut aphid parasite: Release, dispersal, and recovery in orchards

A resistant strain of the walnut aphid parasite Trioxyspallidus performed well in initial field trials. Laboratory studies showed it was also resistant to other pesticides used in walnut IPM.

Survey detects viruses in almond, prune, and sweet cherry orchards Survey detects viruses in almond, prune, and sweet cherry orchards

Prunus necrotic ringspot and/or prune dwarf viruses were found in young orchards in 1988 California surveys.

Usina concentrate postbloom NAA sprays to thin olives Usina concentrate postbloom NAA sprays to thin olives

A concentrate spray was as effective as a dilute spray.

CPPU for Reduced Preharvest Drop and Improved Kernel, Shell and Hull Size in Almond CPPU for Reduced Preharvest Drop and Improved Kernel, Shell and Hull Size in Almond
Treatments of the plant growth regulator, CPPU, did not increase the size of any portion of the nut, or aid in reducing drop. Additional testing is warranted. Submitted to California Almond Board for 2006.
