National Poison Prevention Week — March 19-25, 2017

Never eat while wearing personal protective equipment or without washing up. This increases your risk of pesticide poisoning!
According to the Centers for Disease Control and Prevention (CDC), poisoning is the No. 1 cause of injury-related death in the United States, and 1,073 people in California were poisoned by pesticides in 2014 alone. Each year since 1962, National Poison Prevention Week has taken place during the third week of March to raise awareness about avoiding these tragedies. No one wants their workers or family members to experience illness or death from pesticide exposure, so the UC IPM Pesticide Safety Education Program (PSEP) would like to bring special attention to preventing pesticide poisoning this week. The program also published a new edition of The Safe and Effective Use of Pesticides in 2016, which contains a wealth of pesticide safety and hazard prevention information for people who work with pesticides.

Both agricultural and household pesticides can poison people if they are not properly handled. In agriculture, poisoning most often results from pesticide mixing and loading, and the most harm occurs due to spills, splashes and equipment failure. In the home, many pesticide poisoning incidents involve children swallowing pesticides, including garden products, disinfectant cleaners, or other chemicals used to control pests.

One of the most important things you can do to prevent pesticide poisoning is to follow the instructions on the pesticide label. Labels address critical information about how to use a pesticide safely, including the kind of personal protective equipment (PPE) you should wear to prevent overexposure, how much of the product to apply, the minimum time you must wait to enter the area after applying the pesticide (the restricted entry interval), and the minimum time that must pass between application and harvest (preharvest interval).

Labels also include important signal words such as “Danger,” “Warning,” or “Caution” that indicate how acutely toxic the chemical is to humans, as well as directions to avoid pesticide contamination of sensitive areas such as schools and hospitals. These instructions are meant to protect anyone who is at risk of being exposed to hazardous pesticide residues. It is essential to thoroughly read and understand the pesticide label before working with the pesticide, and to carefully comply with label instructions throughout the process. The UC IPM guide to Understanding Pesticide Labels for Making Proper Applications can help you do this, and is available in both English and Spanish.

Never store pesticides in food or drink containers. It is illegal!

If you apply pesticides in or around your home, be sure to store them properly and keep them out of the reach of children. Keep in mind that even mothballs may look like candy to very young children. It is illegal and unsafe to store pesticides in food or drink containers, which can easily fool people into consuming them and being poisoned. According to the California Department of Pesticide Regulation, these mistakes caused 62 incidents of child poisoning from pesticide ingestion in California in 2014, and 47 of those cases involved children under six years of age.

Read the label every time you handle a pesticide. Don't rely on your memory.

Succulent Color

When we discuss succulents, we often paint them with a broad brush. We think about shades of green, gray and blue, along with an occasional stripe of pink or maroon tingeing their edges. We forget that seasonal temperatures play a role in the intensity of their colors, especially in the winter.

This spring I'm enjoying the effect that our cooler wetter winter weather had on the potted collection of succulents on my patio. The photographs below don't do justice to the vivid accent colors now on display. 

Frankly, I must admit that I used to think succulents needed heat and dry soil to morph from simple greens to vibrant oranges, brilliant reds and deep blues. Not so. Since succulents prefer temperatures in the 70s, extremes in both hot and cold can intensify their color palette.

I'm pleased to say that this year the sunshine yellow daffodils are not the only March performers strutting their stuff in my backyard. They were upstaged by pots full of spectacular succulent color.

Bouquets to Art at the de Young Museum in San Francisco

Bouquets to Art @ the de Young Museum In SF - limited time only from March 14, 2017 to March 19, 2017

There is a very short-lived exhibit called "Bouquets to Art" at the de Young Museum in SF which runs from March 14, 2017 to March 19, 2017 (I assume short-lived because the exhibit can only last as long as the cut flowers do).  This exhibit has been held annually for at least 32 years and is intended to be a fundraiser to support the de Young's special exhibits, conservation projects, and educational programs.  Although I am unable to attend this year's exhibit, I have attended this event in the past and found it to be enjoyable.  Well-known floral designers create elaborate interpretations of paintings that are part of the de Young's permanent collection (paintings mostly depicting flowers) by arranging flowers in such a way to evoke and bring art to life.  In addition to the exhibit, there are lectures ranging on a wide variety of topics related to flora and fauna (note that some have already sold out), which are as follows:
