Almond and Walnut Pest Management Guidelines revised just in time for the holidays.

‘Tis the season for baking lots of tasty treats. Breads, cookies, cakes, and candy are just a few that come to mind. What makes many of these treats so tasty is the addition of almonds or walnuts to the list of ingredients.

In California, we are lucky to be at the center of almond and walnut production. According to the California Department of Food and Agriculture's (CDFA's) latest Agricultural Statistics Review, more than 99% of the almonds and walnuts produced in the United States are grown in California. 

Almond and walnut growers work tirelessly to supply enough nuts to not only satisfy domestic demand, but also for export. Worldwide, almonds rank as the largest specialty crop export. California is the top almond producer in the world, accounting for about 80% of all almonds grown. For walnuts, California ranks as the second largest producer in the world. To keep up with this demand, almond and walnut growers must be constantly aware of pests, diseases, and abiotic problems that can affect the tree and growing nuts. 

The University of California Statewide Integrated Pest Management Program (UC IPM) has recently published revised Pest Management Guidelines for almonds and walnuts, helping growers prevent and manage pest problems with the most up-to-date information. 

Revisions in the Almond Pest Management Guidelines include: 

  • A new section on bacterial spot, a new disease of almond in California found in the Sacramento and northern San Joaquin valleys
  • A renamed section on fruit russeting, revised from the old powdery mildew section
  • Significant revisions made to the management section of navel orangeworm, one of the major pests attacking California almonds
  • Improvements on how to do dormant spur sampling section with easier-to-understand information on monitoring and thresholds

 Revisions in the Walnut Pest Management Guidelines include: 

  • Updated information on the association between walnut twig beetle and thousand cankers disease
  • New sections for Botryosphaeria and Phomopsis cankers, branch wilt, and paradox canker
  • Significant changes to the walnut husk fly management section 

Both the almond and walnut revised Pest Management Guidelines also include updated information on fungicide efficacy, weed management, and vertebrate management. 

Authored by University of California specialists and advisors, the Pest Management Guidelines are UC's official guidelines for monitoring and managing pests in California crops. For more information on pest management in these or other crops, visit the UC IPM website.

It’s time for DPR license and certificate holders to renew—get units via online courses from UC IPM.

November has arrived, and before you know it we'll be ringing in 2018! For those who hold a license or certificate from the Department of Pesticide Regulation (DPR), and have a last name starting with the letter M through Z, this is your year to renew.

DPR is urging license and certificate holders to mail in applications now to avoid late fees and to allow enough time for processing so that you can receive your new license or certificate by the beginning of the new year. Renewing early gives DPR time to notify you if you are short any continuing education (CE) hours and allows you time to complete any additional CE courses without having to retest.

If you need more hours to complete your renewal application and don't have time to attend an in-person meeting, then check out the online courses available from the UC Statewide IPM Program (UC IPM).

The following UC IPM and UC Agriculture and Natural Resources online courses have been approved by DPR and are available whenever and wherever you want to take them.

 Laws and Regulations

  • Proper Pesticide Use to Avoid Illegal Residues (2 hours) $40.00 charge
  • Providing Integrated Pest Management Services in Schools and Child Care Settings (1 hour Laws and Regulations and 1 hour Other)

 Other

  • Citrus IPM: California Red Scale (1 hour)
  • Citrus IPM: Citricola Scale (1 hour)
  • Citrus IPM: Citrus Peelminer (1 hour)
  • Citrus IPM: Citrus Red Mite (1 hour)
  • Citrus IPM: Cottony Cushion Scale (1 hour) 
  • Citrus IPM: Forktailed Bush Katydid (1 hour)
  • Pesticide Application Equipment and Calibration (1.5 hours)
  • Pesticide Resistance (2 hours)
  • Tuta absoluta: A Threat to California Tomatoes (1 hour)
  • Urban Pesticide Runoff and Mitigation: IPM – Pesticide Properties (1 hour) 
  • Urban Pesticide Runoff and Mitigation:  Impact of Pesticides - Urban Pesticide Runoff (1 hour)
  • Urban Pesticide Runoff and Mitigation: Water Quality and Mitigation:  Bifenthrin and Fipronil (1 hour)

For those of you with last names A through L (or those of you who want to get a jump on your CE hours), look for new online courses from UC IPM coming in early 2018.

View the list of all DPR-approved online or in-person courses. For more information on the license and certification program and renewal information, visit the DPR website.
