The registration site is now open for the 66th annual meeting of the California Weed Science Society (CWSS). This year, the meetign will be held January 22-24, 2014 at the Portola Hotel & Spa in Monterey, CA. The theme of the meeting is "Meeting the Challenge for a Hungry World: Weed Management Strategies in the Coming Decade". CDPR has approved the meeting for 18 hours of continuing education (includes 4 laws and regs hours).
For those that have not come to this conference before, it is one of the longest running state weed conferences in the country. It is generally a 2.5 day meeting with around 500-600 attendees ranging from weed scientists to weed managers, to herbicide applicators from around the...

Please fill out this short survey from researchers in UC San Diego.
"We are conducting a short, 3-minute online survey in an effort to understand how different stakeholders perceive and define success in conservation. Your input can help us identify keys to success and will allow us to provide insight into how success is measured and perceived in the conservation community.

Earlier this year, Lynn posted an explanation of herbicide modes of action and what that means for herbicide resistance management in orchards and vineyards.
I thought to myself "Self, we should put this in a table so it would be easy to understand". Then I remembered that we actually did this already in one of the four glyphosate resistance publications that I mentioned in an August posting.
Here's an excerpted table from ANR Publication 8501 "Preventing and Managing Glyphosate-Resistant Weeds in...

Abstract: Reduction in herbicide use in non-agricultural areas is being imposed by a growing number of governments, triggering the development of alternative strategies for weed prevention and control. This study aimed to determine the weed preventive abilities of different paving types, the required treatment frequency of non-chemical weed control scenarios on these pavements and the associated weed species composition. A test parking area, constructed with four concrete paving types, was sown with a mixture of dominant weed species. Six scenarios with repeated use of a single weed control method (brushing with waste removal, hot air, selective application of hot water and three scenarios with flaming) and two...

Saving Glyphosate
Glyphosate, the active ingredient in Roundup, is the most commonly used herbicide in California. Highly effective, safe for the user and the environment, and now inexpensive, glyphosate is a valuable weed management tool. How valuable? Imagine the cost of weed control if you couldn’t count on glyphosate!
Resistance–the inherited ability of a plant to survive and produce healthy seed after being sprayed with enough material to kill non-resistant plants of the same species–has developed to glyphosate in several weeds in California. These include rigid ryegrass, annual ryegrass, marestail (Horseweed), Hairy fleabane, and jungle rice. Glyphosate resistance is a...
