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...

A couple weed control presentations of interest by weed science academics include:

• John Roncoroni "A new focus on weed management"
• Scott Steinmaus "Science and controversy of glyphosate"

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.
