Annual bluegrass is a common winter growing grass in agricultural and urban environments. It is a well-known weed of turfgrass systems but its ability to grow in a range of environments makes it an increasing problem for other agricultural systems. Annual bluegrass has a short life cycle which may range from annual to perennial, seeds can germinate rapidly and multiple times in a growing season and has a high degree of survival when defoliated or trampled (Galera, Chwedorzewska et al., 2015).
All of these traits make chemical control an attractive and primary mode of management for annual bluegrass. This is true for turfgrass systems where managers use regular applications of PRE and POST herbicides and orchard systems where...

Click here for a link to the PDF version on the Weed Research and Information Center page (this is probably your best bet for the most up-to-date version). I've also attached the pdf version at the bottom of this posting as well as the low-resolution image right here. --->
There were quite a few updates to this version compared to the last one I did in early 2016. This reflects both real activity in label expansion as well as...

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

From Cal-IPC's Doug Johnson:
Cal-IPC is proposing additions to our California Invasive Plant Inventory and we are soliciting input during a 60-day comment period. I would appreciate your help in distributing this widely to your interested colleagues.
We are proposing to add:
- Ten plant species that are currently deemed invasive in California, based on completed assessments of impact and spread
- 87 species deemed to be a high-risk for becoming invasive in California. (We completed assessment for 200 species established outside cultivation in California, and these 87 are those that scored “high-risk.”)
