Port Slowdown Impacts California Agriculture

Port Slowdown Impacts California Agriculture

California agriculture exported about 26% of its production in 2013 worth $21 billion. The top six destinations for California agricultural exports are Canada, European Union, China (including Hong Kong), Japan, Mexico, and Korea. Most export destinations rely almost exclusively on West Coast ports. The slowdown did not greatly restrict shipments from California to Mexico and Canada because most shippers use rail and truck for that trade. Exports of some products to…

2014 Lodi Grower Survey – Report of Results

2014 Lodi Grower Survey – Report of Results

It is common, and even recommended, for winegrape growers to collect various types of information, or data, which they then used to make informed vineyard management decisions. PCAs walk vineyards to collect pest monitoring data, which is the basis for pest control decisions. Lab analysis of soil and petiole samples are used to develop nutrient management recommendations. Meteorological data collected by in-field weather stations is used to alerts growers when frost control…

Potential for Biological Control of Brown Marmorated Stinkbug in California

Potential for Biological Control of Brown Marmorated Stinkbug in California

The  brown marmorated stink bug (BMSB), Haylomorpha halys, was first reported in California in 2002 and was found as a live adult in a storage locker in Riverside County. This interception (as opposed to found in the environment) was followed by a similar finding in Vallejo, Solano County in 2005. The first well established, reproducing populations in California were reported from Pasadena in 2006. A large, reproducing population was first…

Vineyard Airblast Sprayer Calibration for Improved Deposition

Vineyard Airblast Sprayer Calibration for Improved Deposition

In November of 2014 I had the opportunity to attend a week-long spray application technology seminar at Cornell University taught by Andrew Landers. Andrew is well known in the industry as a spray technology guru and has come to the Lodi area to spread his knowledge on multiple occasions. A week-long training hardly makes me an expert, but I did come away with a new appreciation for application technology as…

Recommendations for Revising CDFA Regulations on Nursery Stock – Opportunity to Improve the Quality of Vines

The California Grapevine Registration & Certification Program, administered by CDFA, aims to eliminate specific grapevine diseases such as leafroll, fanleaf, corky bark, stem-pitting and fleck that are spread from vine to vine by grafting and/or vegetative propagation. However, for many years, grape growers have been frustrated by the fact that CDFA certified grapevine nursery stock available from participating California grapevine nurseries are often found to be contaminated by these regulated…

Making the Economic Case for Early Adoption of Practices to Prevent Trunk Diseases

Making the Economic Case for Early Adoption of Practices to Prevent Trunk Diseases

All California vineyards become infected at some point by trunk diseases: Botryosphaeria dieback, Esca, Eutypa dieback, and Phomopsis dieback. The symptoms do not become obvious until years 6-8. Trunk diseases limit the productive life of infected vineyards, and can do so only a few years after the breakeven point. The preventative practices of delayed pruning, double pruning, and applications of thiophanate methyl (TopsinM) have been shown to reduce infections. However,…

Hilgardia: A New Old Resource for Viticulture Research

Hilgardia was the primary technical publication of UC Agriculture and Natural Resources (UC ANR) for 70 years. The journal was established in May 1925 and succeeded the Technical Paper series which ceased with issue No. 20 (April 1925). Although production ceased in 1995, the 900-plus issues include classic research making up the cornerstones of agricultural, environmental and nutritional science. These issues are frequently still cited in scientific literature.  Many of…

Cover Crop Performance and Nitrous Oxide Emissions in a Lodi Vineyard

Cover Crop Performance and Nitrous Oxide Emissions in a Lodi Vineyard

Cover crops are a critical piece of a sustainable vineyard system. Retaining plant cover in tractor rows helps reduce soil loss, limiting wind or water erosion. [1] Cover crops also influence vineyard nutrient levels [1, 2]. The inclusion of cover crops in vineyard management plans can also result in less desirable effects such as increased greenhouse gas emissions, especially if leguminous cover crops are utilized [1, 3]. Our study in…

A Checklist to Reduce Spray Drift

A Checklist to Reduce Spray Drift

What I learned in The New Yorker, in an article titled “The Checklist” written by Atul Gawande, and published on December 10, 2007, was that a simple and effective technique for reducing human error is the checklist. Gawande later wrote an entire book on the subject entitled The Checklist Manifesto: How to Get Things Right. For many years I have said that the single best publication that a person can read in the…
