- (Public Value) UCANR: Safeguarding abundant and healthy food for all Californians

Hello
We have been evaluating several herbicides on direct-seed Brassica vegetables: Bok choi, broccoli raab, collard greens, mizuna, mustard greens and radish. We also have evaluated several herbicides in transplanted Brussels Sprouts and Kale. Most of these crops appear to be quite tolerant of Dual Magnum.
The individual trial reports are attached.

In 2017, I started getting reports of a watergrass biotype/species (Echinochloa spp.) that was difficult to control using our suite of herbicides registered in rice. At the time, I knew we had multiple herbicide-resistance in late watergrass (Echinochloa phyllopogon), so I initially just thought the resistant biotype was spreading, and had maybe gained resistance to additional herbicide modes of action. However, once I started visiting fields, it quickly became apparent that this was not late watergrass (phenotypically-speaking). It also did not appear to be barnyardgrass (Echinochloa crus-galli), although the Echinochloa species are notoriously difficult to identify, and phenotypically quite variable in...

Advisors seek practical use of steam in weed control
By Bob Johnson
Steam-treating a shallow band of soil within the seed line before planting may offer, when combined with advanced cultivators, an economical weed control option for organic farmers and conventional growers looking to reduce herbicide use.
University of California specialists said their research in Salinas Valley vegetable fields this year showed the technique can significantly reduce weed pressure...
