Two years ago, I shared my first blog about the Zasso electrical weed control (EWC) unit—a tractor-mounted device powered by the tractor's PTO. (My first blog about the basic of EWC and unit specifications
In spring 2023, we established two organic blocks, one with almonds and one with blueberries, to further evaluate the weed control efficacy and crop safety of the Zasso unit in newly established tree and berry systems. In these trials, we tested different combinations of speed and power to control the total current/energy flowing into the ground. This approach is similar to herbicide trials where we often test at different rates to evaluate crop...

Large scale demonstration of chemigated rimsulfuron treatments for branched broomrape control in California processing tomato
Matthew Fatino, Brad Hanson
Plant Sciences Department, University of California, Davis
Branched broomrape is an obligate holoparasite that can attach to a wide variety of agricultural crop hosts, including tomato. It has been reported in numerous California commercial processing tomato fields in recent years and is of growing concern to the tomato industry in the state. In late 2022, a 24c Special Local Need (SLN) label was approved for broomrape management with chemigated Matrix...

Last week, I shared a press release about theEPA's educational materials toolbox related to pesticides and the Endangered Species Act. Today, I wanted tofollowup with another "explainer" document from the Weed Science Society of America about the current version of the Herbicide Strategy.

from a Weed Science Society of America press release (Oct. 11, 2014)
The U.S. Environmental Protection Agency (EPA) released an online toolbox with educational materials related to pesticides and endangered species -- another step in the agency's efforts to protect endangered species, support farmers, and provide critical environmental protections for communities across the country.
When EPA registers a pesticide or reevaluates it in

One of the first steps in ecological restoration is often controlling invasive weeds, which can be a major barrier to native plant establishment. But what happens after restoration is complete? At most sites, weed pressure is an ongoing challenge that land managers must grapple with to maintain the diversity, structure, and functioning of native plant communities.
The Invasive Weed & Restoration Ecology Lab at UC Davis is currently exploring the use of “competitive planting” as a method for weed suppression in restored grassland communities. As part of a USDA-funded project, we are evaluating what seed mixes can best facilitate the establishment of native perennial bunchgrasses while also preventing reinvasion of...
