Walnut & Almond Pest Management: Preparing for a Successful New Year

By Emily J. Symmes, IPM Advisor UCCE and Statewide IPM Program

With the wild ride of the 2017 growing season now behind us, January is a good time for orchardists to take stock of the key issues of the previous year and begin outlining their production and pest management activities for the upcoming season. During the dormant period, one of the most critical activities that can be done is to sit down with your orchard manager, pest/crop adviser, and your record books to review your pest management history and devise a plan-of-attack for the coming season. Heading into the season armed with lessons learned from successes and failures of previous years,...

Managing Spider Mites in Almonds and Walnuts

By Emily J. Symmes, IPM Advisor UCCE and Statewide IPM Program

Spider mites are considered indirect pests in almonds and walnuts, in the sense that they do not feed directly on the harvested product. Rather, they cause injury to plants by sucking cell contents from foliage. Signs of feeding injury include leaf stippling, yellowing, and dropped leaves. High populations of mites can also be recognized by webbing on leaves and tree terminals. Significant spider mite injury can become economic crop damage in almonds in subsequent seasons in the form of reduced vegetative tree growth and crop reduction. In walnuts, early season defoliation can reduce nut yield and quality that year. In...

Subsurface Drip Irrigation has Pros and Cons in Almonds

By Julie R. Johnson, Contributing Writer

Subsurface drip irrigation in almonds may not be the way to go for all growers in the state, but for two almond operations, Terranova Ranch in Fresno County and 4R Farming in Arbuckle, the practice has proven to be very successful. The use of subsurface drip irrigation (SDI) is nothing new on a worldwide level. In Israel the practice has been around since the 1960s.  SDI has had many diverse uses around the world for a multitude of crops on multiple soil types in various climates. Here in the United States, studies and research into SDI, its advantages and disadvantages,...

Groundwater Recharge In Almonds

By Cecilia Parsons, Associate Editor

With California’s drought in mind, more researchers are delving into plant water use, specifically, plant responses to limited water during the growing season.   University of California plant scientist Ken Shackel, a speaker at the 2016 South Valley Nut Conference, has been working on a project that addresses the opposite situation: how a plant responds to too much water. Shackel’s research project in the northern San Joaquin Valley is looking less at plant water use and more on how almond trees react over time to wintertime flooding of an orchard.  The findings from this multiple year study could pave the...

New Technologies Benefit Nut Processors

By Kathy Coatney, Editor

New technology is expensive, but many times it is worth the investment because of the resulting savings in time, efficiency and improved product.   Electrical Systems Electrical systems have been greatly improved in recent years by the use of PLC's (Programmable Logic Controllers). PLC’s allow huller/sheller operators to initiate operation of all equipment with a single control. Additionally, future equipment can be added by simply changing the PLC program. Changing the program easily allows sequencing of equipment start-up and shut down.   Precleaning Precleaning of field harvested almonds has been improved with the advent of receiving pit vibrating feeder/scalpers. This equipment allows the...
