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...

Even though only a small percentage of ornamental species escape cultivation and become invasive, those that do can have major negative impacts. In California, more than half of the most invasive plants damaging the state's wildlands and natural areas are derived from horticultural ornamentals. PlantRight™ (

Note that it's pretty much the only plant present: it can regrow from small rhizome fragments, and is very tolerant of hot and dry conditions. It's also poisonous to livestock. It is a listed noxious weed in many states and in a number of Mediterranean-climate countries...

This project was spearheaded by Cheryl Wilen (UC IPM) and Jutta Burger (CAL IPC) who worked with a team to develop a Best Management Practices Manual for non-chemical weed control and worked with Tunyalee and UC IPM to build the online interactive interface to access the information.
