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...

Dry Bean Field Meeting
UC Davis
Friday, August 16, 2019, 10 am- 12:00 pm
UC Davis Agronomy Farm
Directions to the UC Davis Plant Sciences Field Facility:Note: this is a different location from previous years:From Hwy 113 in Davis, exit on Hutchison Drive. Go west, and head straight through the first roundabout, then turn left at Campbell Road. The gate to the bean fields will be on your right about 1,300-ft down Campbell Drive,...

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...

With the heavy rains last week and over the weekend, soils are very susceptible to compaction and structural degradation, affecting plant growth. Although it may be tempting to get into the field as soon as the rain stops, the long-term consequences to soil structure are hard to fix.
It's important to wait for soils to dry down before working the field. Heavier soils will take longer to dry down. While tillage or land prep is more harmful to soil structure than driving over the field, even driving over a wet field should be avoided if possible.
Refer to this article from last year about soil compaction for more information:
