Mechanical Weed Control under the Vine
Vineyard floor management can be divided into two areas, the area under the vine and the area between the rows. Cover crops are often planted between the rows and mowed as needed during the season. Under the grapevines, a two- to four-foot strip is kept weed-free with herbicide applications. The most widely used.../h3>/span>

We are having more and more difficulties controlling watergrass over the past 20 or so years. We know that as of the early 2000s, we had found multiple-herbicide resistant late watergrass (also known as mimic), as well as multiple-herbicide resistant barnyardgrass. For early watergrass, we now have resistant biotypes (to thiobencarb), with none recorded as being multiple-herbicide resistant.
In 2017, two rice fields were identified with an unknown watergrass biotype (or species) that looked very different than the three main known species that infest California rice fields (late watergrass, early watergrass, and barnyardgrass). Both fields had...
In a previous article we gave a general background of branched broomrape (Phelipanche ramosa), a parasitic weed which was the focus of a $1.5 million eradication effort four decades ago in California, and now a re-emerging threat to California processing tomato (

Automated weeders remove weeds inside the three- to five-inch-wide uncultivated band left around the seedline by standard cultivation. Automated weeder technology has improved significantly over the past decade. All automated weeders use 1) cameras to detect plants, 2) a computer to process the image and make decisions about which plants to keep and which to remove and 3) a kill mechanism. Kill mechanism that operates in the seedline used by currently available machines are either a split blade that opens around keeper...
