Pair of studies offers evidence into "superweed's" defensive tactics, strategy
FAYETTEVILLE, Ark. — A study of the effects of mowing on a common weed has found that what doesn't kill you can make you stronger.
A study published in Nature's Scientific Reports has found that frequent mowing of Solanum elaeagnifolium may help create a “superweed.”
Solanum elaeagnifolium — also known as silverleaf nightshade — can be found from south Texas to South Africa and Greece, infesting fields and soaking up valuable nutrients intended for cash crops. The weed with purple flowers – sometimes white and light purple – has prickly...

The direct annual cost to monitor and control invasive plants in California is $82 million, and the indirect economic impacts are even larger. Join the fight to reduce noxious weeds and get trained at the 2016 Workshop Series!

Recently I was a participant on an educational noxious weed tour in Sierra Valley. It is a beautiful mountain valley where most agricultural production is devoted to grazing and hay production. The tour was set up by the Plumas Weeds group, to show land managers and ranchers various noxious weeds which are invading Sierra Valley. We discussed identification, biology, and control options for a variety of weed species. One of the questions which was inevitably brought up for each species was: “How long is the soil seed life of this weed?” This question led to interesting conversations.
When we stopped to look at hoary cress (Lepidium Draba) we had a relatively optimistic conversation. Hoary cress is a B list...

A repost and link today to a recent Weed Science Society of America press release entitled: "WSSA Scientists Stress the Importance of Early Response to Invasive Weeds" Click the link to go to the full article.
I'll also give kudos to the WSSA web team on the brand new redesigned (and really sharp-looking Society webpage here: http://wssa.net/ A great resource for weed science info, jobs, and links to issues...

In the United States, only species listed on state or federal noxious weed lists are regulated. According to our analysis, these regulatory lists poorly represent invasive plants in unmanaged (i.e., nonagricultural) systems. To improve the representation of invasive plants on state regulatory lists, we recommend allocating listing authority to invasive species councils and provide guidance for the science-based reform of noxious weed lists. We also recommend commercial best practices to test for invasiveness prior to intentional introduction of new plant products. Finally, we introduce a negligence liability scheme to discourage the introduction of potential invaders. If adopted, our recommendations could benefit nonagricultural...
