The 59th annual Weed Day at UC Davis will be held next week on Thursday July 16th. It's not too late to register but there are only a few spots left before we reach capacity.
CE Specialist Joe DiTomaso is the Weed Day chair this year and he has organized a great morning field tour where we'll look at on-going herbicide trials in tomato, melon, safflower, and nut orchards. We'll also have a demonstration of a machine vision robotic cultivator in transplanted vegetables, a herbicide symptomology demonstration, and a visit to the USDA-ARS aquatic weed research facility. Following tradition, we'll also have a weed ID quiz (with...

For the past couple of years, an important postemergence herbicide active ingredient, glufosinate-ammonium, used in orchards and vineyards has been in pretty short supply (see my earlier post about Rely 280 scarcity).
This was largely due to supply issues caused by unexpectedly high demand in the South and Midwest due by herbicide resistant weeds (particularly Palmer amaranth). The resulting manufacturer supply bottleneck has caused a few weed management challenges (and high prices for limited supply!) in some regions of the state, particularly for growers dealing with our own glyphosate-resistant weed problems in trees and...
