Branched broomrape is a parasitic plant that is an “A-listed” noxious weed in California, requiring crop destruction and a hold order to be placed on reported fields. It has been reported in several commercial tomato fields in Yolo County in recent years and is of growing concern to the California tomato industry. Until recently, there have been no registered chemistries to control branched or Egyptian broomrape in California.
Rimsulfuron, marketed as Matrix SG by Corteva, is registered on tomatoes in California is widely used both PRE...

In the middle of January, the California Weed Science Society celebrated its 75th anniversary with a meeting in Monterey, California. We had a good number of attendees with nearly 550 people registering and attending our conference. There were lots of great presentations made during the sessions. As well as much good discussion in between the breaks, and around the bar.

Sucker control in Oregon hazelnut orchards is a season-long struggle against the tree's natural growth habit. Hazelnut trees grow naturally as a multi-stemmed bush, but in Oregon, hazelnuts are trained as a single-trunk tree to facilitate mechanical maintenance, harvest, and reduce pathogens. In Willamette Valley orchards sucker, or basal sprout growth begins in April and ends in September or October. Managing sucker growth requires multiple applications per season, and hand pruning may be required as well.
Sucker control practices place very young orchards at risk of herbicide injury, because trees from zero to three years old are more susceptible to herbicide damage (Figure 1). Trunk guards and latex paint are used to shield...
