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...

Italian ryegrass (Lolium multiflorum) is an annual grass that can sometimes behave as a biennial or short-lived perennial in California. The species is upright in habit (to about 3 feet in height); seeds germinate in the late fall and the plants grow vigorously through the winter and early spring. Ryegrass can be identified by its dark green, glossy and hairless leaves that are rolled in the bud. Auricles are well-developed and the ligules are long and membranous. Once flowering occurs, ryegrass is easily distinguishable by alternating spikelets that run along the length of the main flowering stem (April through September). Additional photos can be found at the end of this post; more details regarding Italian ryegrass...

Weeds compete with crops for light, water, and nutrients, which can result in yield reductions. Weeds can also interfere with crop production by serving as alternate hosts for pests and pathogens, providing habitat for rodents, and impeding harvest operations among other impacts. Natural areas can also be impacted by weed species when they reduce aesthetics, cause physical harm, and disrupt ecosystem services. As a consequence, growers and land managers employ a variety of control strategies, including the application of herbicides, to manage unwanted vegetation.
Although herbicides can be extremely effective at controlling undesirable plants, failures can and do occur. Weeds may escape chemical treatments for several reasons...

Glyphosate was commercialized in 1974. Since then, it has become one of the most widely used and studied herbicides. According to Duke (2018b), almost 20,000 scientific publications and patents have included glyphosate as a focus; only 2,4-D surpasses it with respect to citations. The articles in the 5th issue of the 74th volume of Pest Management Science are no different; they all focus on this important (and controversial) molecule.This special issue arose from a day long symposium organized by Stephen O. Duke (University of Mississippi) and Keith Solomon (University of Guelph) that was held at the 252nd annual meeting of the American Chemical Society (Duke 2018a).
