My name is Clebson Gonalves and I am the UC Cooperative Extension (UCCE) Diversified Agricultural Systems Area Advisor for Lake and Mendocino counties. My educational background consists of studies focused on plant production, crop protection, and weed science.
Winter annual grasses are one of the major invaders on rangelands in the intermountain region. They also can be problematic in a variety of systems from farm ground to forestry (cheatgrass in particular).
New varieties of rice that offer more effective weed control with less herbicide were showcased by UC Davis Department of Plant Sciences researchers at the recent Rice Field Day north of Yuba City in California's Central Valley.
Oregon leads the United States in the production of Christmas trees, with almost 8.5 million trees sold in 2015. Weed control is essential in Christmas trees to reduce competition for moisture and nutrients, allow fast and robust tree growth, and ensure growers top prices for high-quality trees.
