I recently participated in a UCCE meeting focused on orchard management decision making when times are hard. This was in the context of the current low walnut prices facing producers in the state, but given the cyclic nature of agriculture could easily apply to other perennial crops as the ups and downs of agricultural commodities respond to domestic...

Concerns about a growing resistance to herbicides
In Mediterranean or arid climates, particularly in areas with marginal soils, crop rotations are often limited to a narrow range of hay, pasture, a handful of winter legumes, or rainy-season grasses. Arid conditions and weathered soils drove Australia's rainfed grain growers to adopt no-till strategies earlier than their counterparts in California. While beneficial from a water use perspective, successful no-till systems depend on herbicides to control weeds that were traditionally kept in check with tillage.
Dependence on herbicides alone in these systems has resulted in weeds with resistance to multiple modes of action. In Australia, there is one...

Summary Note
Mechanical cultivation is a useful tool in controlling herbicide-resistant Italian ryegrass individuals in a rainfed wheat system but is only about half as effective as Axial in reducing overall pressure from Italian ryegrass (expressed as a percentage of total groundcover). Growers should consider multiple approaches (chemical and mechanical) and integrate IPM strategies to reduce the spread of resistance among...

If you grow rice in California, you already know that effective weed management is not only essential for economical rice production, but also very challenging, complex, and regulated. The good news is that there is a new resource to help growers and pest control advisors with the prevention, monitoring, and control of the most common rice weeds in California. The University of California Integrated Pest Management (UC IPM) Pest Management Guidelines: Rice now includes a brand new weed management section!
The guidelines are authored and reviewed by University of California's advisors, specialists, and faculty to bring the...
