There will be TWO upcoming weed science extension days in the San Joaquin Valley this April.
The first will be held on the 2nd of April at the Kearney Agricultural Research and Extension Center in Parlier (9240 South Riverbend Road, Parlier CA 93648) and the second will be held on April 11th at the Westside Research and Extension Center in Five Points (17353 West Oakland Avenue, Five Points, CA 93624).
The meeting at the Kearney Center will focus on rangeland, turf, and tree and vine systems while the meeting at the Westside Center will focus on agronomic crops, ROWs, and tree and vine systems. Both meetings will open with hands-on weed ID and nozzle selection/drift...

NOTE: A graduate student at CSU Fresno is looking to describe the geographic distribution of alkaliweed in California. Please see the end of the article for a link to a QUICK survey describing where YOU have encountered this species.
Growers (mainly pistachios) and crop consultants in the southern and western parts of the San Joaquin Valley have recently reported the spread of alkaliweed from low-lying saline or alkaline soils (including seasonal wetlands and floodplains) into irrigation ditches, orchards, and some agricultural fields.

What are mistletoes?
Mistletoes (Arceuthobium spp. [dwarf mistletoes], Phoradendron spp. [American mistletoes], and Viscum album. [European mistletoe]) are evergreen, flowering plants that parasitize trees and shrubs to acquire water and nutrients. All dwarf and American mistletoes occurring in California are native species whereas Viscum album was introduced to California from Eurasia. Although sometimes considered as undesirable pests, mistletoes may be important components of local ecosystems. For example, the seeds of some mistletoes can serve as food sources...

The first step in developing an effective weed management program is being able to properly identify the weed species that are infesting a field. But why? Why is weed identification so important? Simply stated, because not all weeds are created equal. Species differ with respect to their emergence timing, life history traits, competitive interactions with the crop, potential to harm livestock, and sensitivity to available herbicides, among other characteristics. Consequently, the type and timing of weed control events need to be designed to target problematic species so that control is maximized, weed seed return to the soil seedbank is minimized, and crop yields are protected.
Unfortunately, weed identification is not a simple...
