It’s that time of year when hot weather fuels the creation of ozone, or smog. Some pesticides emit volatile organic compounds (VOCs) that contribute to ozone formation. Using pesticides that release VOCs may be restricted in certain California locations between May 1 and October 31.
If you plan to apply a pesticide, use the Department of Pesticide Regulation’s VOC calculators to determine emissions from fumigant and nonfumigant pesticides. Get there by clicking the Air Quality button at the top of each treatment table in the UC IPM Pest Management...

It's National Pollinator Week. Have you hugged your pollinators today, particularly the bees?
If you don't pay attention to the bees around you, you may think that every floral visitor is a honey bee (Apis mellifera) or a bumble bee (Bombus).
If you look closely, you'll see bee diversity: leafcutter bees, green metallic sweat bees, cuckoo bees, long-horned bees, carpenter bees, and squash bees, just to name a few.
Native pollinator specialist Robbin Thorp, UC Davis emeritus professor of entomology, has detected 80 different species of bees - and counting -...

A glorious foothill display of yellow flowers and their spicy-sweet fragrance may delight the senses, but they pose a serious problem for California.
Scotch, Spanish and French broom were introduced from Europe in the mid-1800s as lovely, easy-to-grow garden accents and land stabilizers, but they have become aggressive invaders threatening native plants and increasing fire hazards.
“These brooms crowd out our native flora and form large, dense stands of just broom,” said Scott Oneto, UC Cooperative Extension advisor in the Central Sierra. “It’s also displacing the birds and animals that would live in this environment with native...
