UC Weed Science (weed control, management, ecology, and minutia)

James Schaeffer and his UCCE and CSU Fresno colleagues are conducting a survey to gather information on a relatively new weed problem in orchard crops of the San Joaquin Valley.

Occasional good news on the weed front...

Back in 2017, I wrote a brief blog about myrtle spurge being present in Lassen County. Myrtle spurge was evaluated by CDFA and determined to warrant being placed on the A list of noxious weeds here in California.

You just KNOW that some plants are considered weeds. Their common names give them away. They sound awful. Giant hogweed (Heracleum mantegazzianum). Ripgut brome (Bromus diandrus). Devil's claw (Proboscidea lutea). Smellmelon (Cucumis melo). Itchgrass (Rottboellia cochinchinensis).

The environmental conditions under which parental plants are grown can affect the progeny population in many ways.
