Tarweeds, vinegarweed and turkey mullein are native forbs that stand out in Fresno and Madera County rangelands during the summer. Unfortunately, they aren't the most welcome. Horse owners despise tarweed because its sticky resin turns even brightly colored horses a grim muddy color; many rangeland owners dislike vinegarweed for its pungent smell; and turkey mullein, though common, is often disregarded until it looks like it has taken over dozens of acres overnight.
Although their native status may appease some landowners – they can provide food and habitat for some bird and pollinator species – most ranchers couldn't care less. Why, you may ask? These plants are poor forage for livestock, and most animals tend to...
Southern San Joaquin Valley rangeland owners and land managers are invited to an upcoming weed management workshop in Tulare on Tuesday, May 1, 2018. Online registration and agenda information is available at: http://ucanr.edu/weeds2018
In the job listing for my position, weed identification and management were never explicitly mentioned. “Natural resource efforts” in the listing only mentioned water, forage, soils and “the wide array of issues” relating to rangeland ecosystem services. Of course, pests are an issue relating to rangeland ecosystem services (healthy water, soil, and air; biodiversity; etc.), but when I first joined UCCE, I did not expect to spend a large amount of time on weeds.
Now I know, a year and a half in, an incoming phone call is more likely to relate to weed management than to any other topic. Ranch visits for any purpose will usually include a discussion of weedy species on the property. While weed management is...
As a livestock and natural resources advisor, I don't expect to get questions about fruit trees such as figs. As it turns out, I recently needed to know just enough about figs to provide information on how to kill them - a west Fresno County landowner contacted me to ask how he could get rid of some fig trees that were threatening his belowground water pipelines.
Before writing this post, I did my due diligence and confirmed that no one has already discussed fig trees as the target of weed control on this blog. The only mentions of fig trees in the UC Weed Science blog history are a listing of approved herbicides to control weeds in California subtropical crops as of 2 years ago1 and a mention that fig was one of...
