Understanding Almond Disease Vectors and Recognizing Disease Symptoms

Understanding disease vectors and recognizing disease symptoms can allow for timely management decisions in almond production. Mohammad Yaghmour, University of California Cooperative Extension (UCCE) orchard systems advisor for Kern and Kings counties, explained differences and similarities among vector-transmitted bacterial and viral disease of almond trees and how the diseases are transmitted at the South Valley Nut and Citrus Conference. A typical disease triangle includes host, pathogen and environment, Yaghmour said, but vectors can also play a part in spread of disease. Almond Leaf Scorch The bacterial disease Almond Leaf Scorch (ALS) is vectored by insects and can become a chronic...

Making the Best Use of Irrigation Management Tools

Decisions about irrigation water management in tree nut crops can make or break a growing season. Effective water management, said University of California Cooperative Extension (UCCE) Fresno County nut crops advisor Mae Culumber, should support high yield potential and favor desirable nut quality. Effective Water Management In her presentation at the South Valley Nut Conference, Culumber noted that effective water management can extend orchard life, assist in pest management, use water and energy efficiently, contribute to nitrogen management and mitigate salinity problems. Using irrigation management tools can help growers achieve those goals. Irrigation water management is applying water according to...

Does Late Winter Shaking Reduce Yield Potential in Almonds?

Last year I conducted a research trial in almonds to address a recurring question posed by many growers. Does late shaking of almonds for winter sanitation of mummy nuts reduce the yield potential due to the removal of many of the swelling buds? The 2018 replicated trial in two different orchards indicated it did not. This trial was repeated at two additional sites in 2019 to see if the results could be duplicated. Winter Shaking Winter shaking of overwintering mummy nuts is the single most important cultural activity an almond grower...

BeeWhere: California’s Hive Location Program

There’s no disputing the value bees hold in food production. This is why California has launched BeeWhere, an online tool to help improve communication among growers, pesticide applicators, beekeepers, and other agricultural personnel in order to safeguard hives that are out in the field. “[We] hope BeeWhere will accomplish the notification of all beekeepers when a product will be sprayed in the environment that could be potentially detrimental to the honey bees,” says Karine Pouliquen, M.A., Head Beekeeper under the Orange County Master Gardener Program located at the University of California South Coast Research and Extension Center. That’s exactly what...

2020 Almond Pollination Market: Economic Outlook and Other Considerations

The following article summarizes my outlook for the 2020 almond pollination season in terms of estimated demand for colonies, pollination fees, and other information I believe almond growers will find useful. Where possible, information is based on research and data, however some of the outlook comes from my best educated guess given the information available. In 2020, approximately 1.2 million bearing acres of almonds will require roughly 2.4 million colonies for pollination services. 2019 Almond Pollination Market According to the 2019 California Almond Objective Measurement Report, there were 1.17 million bearing acres of almonds in 2019. This brought in roughly...

What We Know About Winter Chill and Pistachios

Eighty-degree days in the month of November did not send California pistachio trees into their winter rest period on schedule. With harvest at an end and irrigations done to fill soil profile, the trees were primed to enter their needed dormant stage, but warm days and barely cold nights are not conducive to sending pistachio trees into dormancy. (Editor’s note: the end of the month brought some welcome cold to pistachio growing regions in the San Joaquin Valley. How the remainder of the dormant season plays out is yet to be seen.) Industry Research Industry research has determined a lack...
