Over the weekend, the Sacramento Bee published an article discussing the invasiveness and spread of yellow starthiste (Centaurea solstitialis) in California. http://www.sacbee.com/2011/08/21/3847369/invasive-yellow-star-thistle-aims.
Today I'm asking for input from folks who work in orchard and vineyard weed control (land owners, managers, pest control advisors, sprayer operators, etc.) on your take on herbicide resistant weeds.
The nursery industry has introduced thousands of ornamental plants, but only a small percentage (~1%) has escaped to become invasive and cause economic or ecological damage. Thus, the removal of these known invasives should not present a major economic hardship on the industry.
Field Bindweed (Convolvulus arvensis) The late spring rains that fell in Northern California seemed to benefit some plants more than others. One weed that appears to be doing very well this year is Field bindweed.
