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>
Days are getting shorter and evenings cooler as winter approaches. Sweater weather also means a change in the to-do list around the yard.
Here are a few things to consider when preparing your landscapes and gardens for winter.
- Protect sensitive plants from cold injury when freezing or frost is predicted. Cover plants with cloth or a similar material at night, leaving the covers open at the bottom so heat from soil can help warm plants.
- When frost or freezing is expected, irrigate dry topsoil at least 3 days before the cold weather to increase the soil's ability to retain...
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...
Many gardeners and landscapers enjoy growing and caring for roses. Through careful selection of varieties and appropriate cultivation, roses can be grown with a minimum of pest problems. Establishing rose plants to grow in environments with adequate conditions will allow them to grow well, while reducing their susceptibility to pests.
Find more information on growing healthy roses in UC IPM's newly updated Pest Notes: Roses in the Garden and Landscape: Cultural Practices and Weed Control, authored by John Karlik, Environmental Horticulture Advisor with UC Cooperative Extension, Kern County.
