Vineyard Views & Events
Latest information on viticulture, UC research and newly released UC publications.
The results of the Napa County 2013 VMB Trapping Program are now available as downloadable maps on the Agricultural Commissioner's website.
Vine mealybug (VMB) is a serious invasive pest of grapes in California. In 2012, the Napa Agricultural Commissioner's office, with support from the Napa County Wine grape Pest and Disease Control District, implemented a more intensive VMB survey program, using pheromone-baited sticky traps. All vineyard acreage in Napa County was trapped for VMB at a density of 25 traps per square mile. These trap results are now available on the Napa Agricultural Commissioner's website
For additional information on vine and grape mealybug populations in Napa County, please see the UCCE-Napa Vineyard Mealybugs newsletter.
|California Farmers & Ranchers Offered Drought Help||
USDA’s Natural Resource Conservation Service (NRCS) is providing information for farmers and ranchers interested in applying for $20 million in drought assistance. The initiative will provide assistance to farmers and ranchers to install conservation practices. Top priority will go to helping farmers without access to water who need to protect fragile, uncovered soil.
Farmers and ranchers should consult with their local NRCS office as soon as possible in order to apply for assistance. Deadline to apply for assistance is March 3, 2014.
Napa County farmers and ranchers can contact: Rita Steiner at (707) 252-4189 ext. 101 or Kelly Gin at (707) 252-4189 ext. 104. Other counties can contact the NRCS in Davis, CA at (530) 792-5600 to find your local county contact information.
To help ranchers, NRCS can offer practices such as livestock well development, piping, troughs and fencing.
To help farmers who have access to water and want to make every drop count, NRCS can provide improved irrigation hardware with an irrigation management plan to optimize efficiency.
For cropland, NRCS can help with irrigation water management and flow meters and other practices as well.
There are 32 practices on the list, allowing NRCS to provide financial incentives to implement these practices. A few of the practices include: cover crop, critical area planting, mulching, dust control on unpaved roads and more.
Additional information can be viewed from the news release from USDA Natural Resources Conservation Service.

|Water limiting (drought) conditions||
Resources for water management of grapevines under drought conditions (courtesy of our colleagues in Australia) are available in the Irrigation section of the UC Cooperative Extension-Napa County website: http://cenapa.ucanr.edu/Napa_County_Programs/Viticulture/Irrigation/
Considerations for managing vine growth & yield under water-limiting conditions include:
1. Managing crop size through reductions in bud numbers and/or thinning after set. Adjust crop size to predicted water availability.
2. If possible, target supplementary irrigation to critical physiological periods: (a) budburst to flowering, (b) flowering to fruit set, (c) veraison to harvest, (d) harvest to leaf fall--hopefully will be raining by then!
3. Organic residues (from cover crops or weeds) and mulches may moderate soil surface temperatures.
