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

Pokeweed can outcompete native or landscape plants, contaminate agricultural produce, and reduce forage for livestock. All parts of the plant, including the glossy purple-black berries, are poisonous to humans.
Pokeweed is spread by seed and often sprouts in areas where birds roost. The best way...
Public concern regarding the risk of illness from long-term exposure to glyphosate is on the rise. In order to reduce exposure to this common herbicide, or any other pesticide, it's important that applicators wear the right personal protective equipment (PPE), not only for personal safety, but also to comply with California regulations.
Signal words and glyphosate
Pesticide labels contain a signal word, which describes the effects of acute or immediate toxicity from unprotected exposure to the chemical. Signal words are CAUTION, WARNING, DANGER, and DANGER-POISON (see the Spring 2019 issue of the retail newsletter for more/h2>

When using any kind of pesticide, including herbicides, it's important to read the pesticide label carefully and to be sure that you have the proper equipment for applying the pesticide correctly and safely. You will need certain clothing to protect yourself from the unwanted effects of acute (immediate) and chronic (long-term) exposure, even when applying organic or lesser-toxic pesticides.
Personal protective equipment, or PPE, is the term used for clothing and eyewear that act as a barrier between your body and the pesticide. However, for home use pesticide products, PPE is not always listed on the label—some simply say to avoid contact with eyes, skin, or clothing. So how do you know what to wear?
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...
