Knotweed Symposium
science & management webinar

Wednesday, March 1, 2023

The webinar is intended to share information on control of Japanese knotweed, Fallopia japonica, with researchers, land managers, and landscape professionals who work with riparian weeds. The webinar will emphasize attempts at practical control strategies for California's Central Coast within a broader context of its ecology.

In 2022, I estimate rice acreage in the Delta, south of the Yolo Bypass, was at least 8,000 acres. Most Delta rice is grown in San Joaquin County, but there is some acreage in Sacramento County. While Delta rice acreage is relatively small compared to that in the Sacramento Valley, it has been steadily increasing over the last several years (Table 1).

Given the increasing interest in rice production among Delta growers, and the differences in production practices from the Sacramento Valley, UC Cooperative Extension and UC Davis will be releasing a cost of production report specifically for Delta rice later this year or in early 2023. A Delta rice cost study was...

Agronomic cover crop management supports weed suppression and competition in California orchards

Steve Haring and Brad Hanson (UC Davis)

Abstract

Cover crops enhance the biodiversity of cropping systems and can support a variety of useful ecosystem services, including weed suppression. In California orchards, cover crops are typically implemented as annual plants that can replace resident vegetation in orchard alleyways during the rainy winter season. Our research objective was to evaluate cover crop management factors that support a...
