UC Cooperative Extension entomologist Larry Godfrey, a 26-year member of the UC Davis Department of Entomology and Nematology faculty and widely known for his research on applied insect ecology and integrated pest management (IPM) strategies, died April 18, succumbing to cancer. He was 60.
Dr. Godfrey was internationally acclaimed for his research on rice and cotton. He was heavily involved in developing IPM to maintain the sustainability of California agriculture, seeking “to reduce the ‘footprint' of agriculture on the environment and society, and to advance the science of entomology and applied insect ecology.”
At UC Davis, he...
It's not clear that alfalfa growers fully knew that one of the most widely-used insecticides in their crop was about to be completely eliminated from use nationwide.
But it was - nearly. NOT an April Fools Day joke!
A complete withdraw of ‘tolerances' (legal uses) for chlorpyrifos (Lorsban, Lock-on) was scheduled for 31 March, 2017 but on 29th March, the US Environmental Protection Agency (EPA) made a decision that it would not proceed forward at this time with a revocation of all uses for this pesticide.

According to the Centers for Disease Control and Prevention (CDC), poisoning is the number one cause of injury-related death in the United States, and 1073 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...
As if one more example of our interconnected world was needed - the depletion of an aquifer 8,000 miles away is likely to impact on alfalfa growers in Seeley, CA or Pasco, Washington.
Figure 1. Compressed hay awaiting export, Long Beach, CA
Seeley and Pasco (the Imperial Valley of California and the Columbia River Basin of Washington, respectively) are major producers of hay for export. Exports are a key aspect of hay markets in the entire western US, and have buoyed hay prices in the past two years, as domestic dairies have been in an economic slump. Exports have grown considerably the past 10 years (

Fiddleneck is everywhere this year, and common groundsel is common too! As winter annuals, these weeds are early-season plants. They tend to be shallow rooted, and do best in wet conditions like we've been having with all our rainfall this season.
Colorful but Deadly. Fiddleneck (Amsinckia spp.) may look bright and colorful on our hillsides, but this weed, as well as groundsel (Senecio vulgaris), are toxic to livestock, because they contain toxins known as pyrrolizidine alkaloids (PAs) that affect the liver. Cattle and horses are most sensitive to PAs; pigs and chickens are less sensitive, and sheep, goats and turkeys are the least sensitive. Younger animals are more susceptible than...
