You can also get a great deal of information from the WSSA web resource on the topic https://wssa.net/endangered-species/
Today I wanted to share a WSSA link to a webinar presentation "Endangered Species Act and Pesticides: an Example" made by Dr. Bill Chism who is the chair of the WSSA ESA Committee (I'm also on that...

Several of us are part of a multi-state project on electrical weed control in organic blueberry and orchard crops.

From the Cornell team: We are conducting a survey on grower attitudes towards establishing wildflower strips. This survey is part of a project we are doing on using seed pellets to establish wildflower strips. The basic idea of the project is to put multiple small wildflower seeds into a seed pellet the size and shape of a field crop seed. These pellets could then be planted using standard grain drills/planters, significantly...

The USDA Agricultural Research Service's Invasive Species and Pollinator Health research unit recently shared their annual activities report. There are several interesting updates on biological control of weeds and management of aquatic invasive weeds that are highly relevant to California weed managers and land management folks.
The full report is attached at the bottom of this post, but here are a few of the topics that grabbed my attention and might be of interest to the readers of this blog:
- Invasiveness of yellow flag iris (Iris pseudacorus L.) with climate change
- Biological control of yellow...
