Weeds in the landscape can be tough to manage. But there are many options for weed management using an integrated approach that combines nonchemical and chemical methods.
- Start by identifying the weeds you want to manage. UC IPM has a weed photo gallery that includes most weeds found in California landscapes. Knowing how a weed grows and spreads is an important step in successful control.
- Once you know what weed or weeds you're dealing with, consult the Pest Notes series on weeds to find specific management options.
UC ANR's charge is research and extension and we provide guidance about how to manage weeds using registered pesticides and by non-chemical methods. UC ANR includes information in its publications on how to effectively and safely use glyphosate where it is legal to do so as well as provide options for alternative chemical and non-chemical approaches for managing weeds.
UC ANR recognizes that the use of any pesticide carries risks, including in some cases the possibility of acute (immediate), chronic (long term) or carcinogenic effects, to those who may be exposed to them. This is true of any pesticide, which includes herbicides such as glyphosate.
UC ANR has not specifically addressed carcinogenicity or other health...
