Weed resistance issues are nothing new for university researchers and the farmers they advise.

Nevertheless, science continues to partner with agriculture to find ways to address the challenges of herbicide resistance in crops like tomatoes, melons, and a host of other agricultural applications.

The popular Weed Day at the University of California stands as a shining example of such concern. For at least the last five years. the annual event has drawn a capacity crowd to address herbicide resistance to weeds impacting everything from rice to rangeland and row crops to trees.

The 58th annual Weed Day at UC Davis drew about 160 participants, according to university weed scientist and event Chairman Brad Hanson.

The purpose of the event is to draw people together to discuss the science related to weed control measures, Hanson said.

“Beyond the specific research that is presented at Weed Day, this serves as a great networking opportunity for many of us that work in weed control in California,” said Hanson. 

One such topic of continual research is what Lynn Sosnoskie; an assistant project scientist at UC Davis is working on related to tomatoes and melons.

According to a paper written by Sosnoskie, Hanson, Seth Watkins and Oscar Morales with the UC Davis Department of Plant Sciences, several factors have combined to aid the proliferation of bindweed in processing tomatoes.
