UC Weed Science (weed control, management, ecology, and minutia)

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.

Experimental robots are reducing the costs of hand-weeding by learning the difference between weeds and lettuce.

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.

Thanks to Steve Fennimore (UC Davis Cooperative Extension Weed Specialist) for sharing the following. "These inventors in India made a smart weeder with a smart phone. There is hope for low-cost smart weeders!" https://youtu.
