Join UCCE's Grain Cropping Systems Specialist, Mark Lundy next week (11 a.m. on November 6th, 2020) for a presentation on nitrogen management in California Small Grains (hosted by the California Wheat Commission and Golden State Grains).
Dr. Lundy will review methods of measuring soil and plant nitrogen status. This will include some of the decision-making tools being developed by UC agronomists, and discuss methods and strategies for nitrogen management/ monitoring in California small grain rotations. Registration is free.

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 Italian ryegrass individuals.
Background
Italian ryegrass (Lolium multiflorum) has been shown to be a persistent weed for growers in rainfed winter grass systems. It is particularly problematic due to its...

Wheat season is a few months away, but after a pathogen-friendly winter, growers may want to keep an eye out for fungal diseases in the coming season. Warmer temperatures and consistent rainfall last winter created an ideal environment for diseases of winter grasses in the southern Sacramento Valley. High disease rates last year meant some depressed yields in susceptible fields and, if conditions are right, could potentially lead to greater outbreaks next year due to higher inoculum loads.
Septoria leaf blotch (also known as septoria tritici blotch, STB) is caused by the fungal...
