Sharing a survey seeking input on tree and vine cropping system weed control practices and interest in novel technologies as we develop research ideas and priorities with colleagues (and former UC weeders!) around the country.
Weeds can be a significant problem in berries, tree fruits, tree nuts, and vine crops (e.g. grapes, hops, etc.) especially after transplanting and during flowering and fruit and nut set. Herbicides are a.../span>
A quick post to share a link to the most recent version of the CWSS Research Update and News from the California Weed Science Society.
Lots of good information about the upcoming conference, weed science student scholarships, and weed management reports compiled by CWSS Board Member and Editor, Whitney Brim-DeForest. Including:

Mechanical cultivation is a useful tool in controlling herbicide-resistant Italian ryegrass individuals in a rainfed wheat system but is only about half as effective as Axial in reducing overall pressure from Italian ryegrass (expressed as a percentage of total groundcover). Growers should consider multiple approaches (chemical and mechanical) and integrate IPM strategies to reduce the spread of resistance among...
James Schaeffer and his UCCE and CSU Fresno colleagues are conducting a survey to gather information on a relatively new weed problem in orchard crops of the San Joaquin Valley. The species, alkaliweed (Cressa truxillensis) is a native perennial that can be a really difficult weed to control because 1) it is a perennial so not very senstive to PRE herbidies, 2) it is not very sensitive to glyphosate, and 3) it is very tolerant of saline soils where many other plant species do not grow well.
