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:
A reminder to please join us for our annual UC Small Grains/Alfalfa-Forages Field Day next week! This event is on May 15th at the University of California, Davis Department of Plant Sciences Field Headquarters from 8AM – 4:30PM.
This field day showcases UC efforts in breeding and agronomic research related to small grains, alfalfa and forage crops and is one of the longest running field days in the state. The schedule for the day is available
Fava Bean Nitrogen Fixation Trial Field Day
Fava bean is an ancient food crop that is extensively grown and consumed around the world. In California, fava bean is largely grown as winter cover crop to protect the soil and add to soil nitrogen. In this field day event, several speakers will talk about the benefits and selection of cover crops for different cropping systems. We will also demonstrate a field trial that aims to identify fava bean genotypes with enhanced nitrogen...
