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...

The foundation of an effective extension program is an understanding of needs. Although I have worked in California, previously (2012-2017), as a weed scientist with the University of California – Davis, most of my time was spent in specialty crop systems (trees and vines, processing tomatoes, and melons). Consequently, I entered my current position as an Agronomy and Weed Science Advisor less familiar with the concerns and requirements of the agronomic crop industry.

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...
