Weed management in landscaped areas can be challenging. Weeds may need to be controlled for public safety, fire reduction, aesthetics, and elimination of harborage for other pests. While many nonchemical options for controlling weeds exist—such as physical removal with tools, steam, flame or steam devices, grazing animals, and others—there are some situations that may require the application of herbicides.
For decades, glyphosate has been a common active ingredient used to control weeds in both agricultural and nonagricultural settings. However, there has been significant public concern about the use of glyphosate and other herbicides due to their potential...

Knowing what weedy grass you have in your lawn or landscape is very important in being able to properly control it. Dallisgrass is a common perennial weed that is easily identified and grows in uneven clumps in lawns and turf. This growth pattern creates a tripping hazard as well as a poor playing surface for parks, front lawns, and athletic fields. Clumps must be dug out to prevent its growth. Solarization with clear plastic can help control dallisgrass.
For more details about the biology of dallisgrass, management methods, and extensive information about herbicides, see the newly updated Pest Notes: Dallisgrass, authored by UC Cooperative Extension...

As the days get shorter and the temperatures begin to cool, now is the time to practice weed management for annual cool-season weeds. It's also not too early to consider management for weeds that emerge in springtime.
Using integrated pest management (IPM) methods can help reduce the presence of most weeds. In lawns, good practices such as proper watering, mowing, and fertilizing can help maintain healthy turfgrass. Likewise, in landscapes, hand-weeding, cultivation, and use of mulches can be effective in controlling weeds. More specific information about these and other IPM practices can be found in our Pest Notes publications on
