2nd Generation Red Scale Crawler Activity Soon

The 2nd crawler emergence begins at 1650 degree days (above a 53^oF threshold after the 1st male flight in early March).  Kern and Tulare counties will be reaching that threshold next week. See my web site for details: http://ucanr.org/sites/KACCitrusEntomology/Home/California_Red_Scale/Degree_Days_885/

Pesticides like Movento that require 1-2 weeks for uptake should be applied now.  Products that kill crawlers directly such as organophosphates and oils should be applied as soon as the peak of crawler activity has been completed.  Use crawler tapes to define that point in time more clearly. Wrap double sticky tape  around a branch near female scales and replace and examine it once a week to count the crawlers caught along the edge of the tape.  This will telll you when the crawlers are actively emerging.  Insect growth regulators such as Applaud and Esteem should be applied after the crawlers have finished emerging because contact with the scales is important and it these products are not going to kill the scales until they try to molt to the next instar.

Fair exhibit a tribute to Marin's first advisor

UC Cooperative Extension's first farm advisor in Marin County was featured in a story written by Vicki Larson in the Marin Independent Journal. 

M.B. Boissevain, who became a UCCE advisor in 1920, took approximately 500 photos of Marin agriculture and its people during his 30-year career. Ellie Rilla, UCCE advisor in Marin County, and David Lewis, UCCE director and advisor in Marin County, assembled an exhibit of 74 of his photos that was on display at the Marin County Fair June 30 ­– July 4. 

Lewis and Rilla have also written a book, “Marin Agrarian Roots,” about the agricultural history of the county based on Boissevain’s photos and farm reports.
