Yesterday, I attended the Southern San Joaquin Valley Olive Day organized by UC Cooperative Extension orchard systems farm advisor, Elizabeth Fichtner (UCCE Tulare Co). She organized a nice half-day program that included presentations on weeds (from yours truly), olive disease problems, insect pests, irrigation, fertility, and economics. Industry representatives also gave updates on the state of the table olive and olive oil industries. Elizabeth is planning to post most of those presentations on the Tulare Co page (see link above) for those who weren't able to attend the meeting.
My presentation from the meeting are below and included both general orchard weed issues as well as a few specifics for olive orchards. Like many orchard systems, weed control options in olives is limited somewhat by cultural practices and herbicide registrations. Also, like other systems, the primary herbicide active ingredient is glyphosate. Integrated weed management practices are encouraged to minimize selection for resistant and tolerant weed species.
Take care,
Brad
