WEATHER OUTLOOK and TOOLS

Long Range Outlook… Growers are probably wondering if this upcoming rainy season will be a benefit to the water picture for 2017. Present long range outlooks are calling for a weak La Nina to develop over the waters of the Equatorial Eastern Pacific this fall and remain in place at least through the winter months. These slightly cooler than normal conditions would be in sharp contrast to the moderate strength…

MAKING VINEYARD MANAGEMENT DECISIONS

MAKING VINEYARD MANAGEMENT DECISIONS

At the most basic level, business management involves setting goals, planning, organizing, staffing, directing, and controlling.  Vineyard management, of course, is more complicated than this, especially given large amounts of borrowed capital, increasing regulations, rising investment per worker, intensifying needs for mechanization, the dynamics of the wine grape market, and the increasing sophistication of grape growing and expectations of grape buyers.  Also, unlike nonagricultural business endeavors, grape growers must positively…

Fruit Set Factors

Fruit Set Factors

Fruit set is the process in which flowers become fruit and potential fruit size is determined.  It occurs after pollen is released from male flower parts (anthers), lands on receptive female flower parts (stigmas), produces a tube that grows to the ovules, and fertilizes eggs contained in them.  Fertilized eggs form seeds, which induce surrounding (pericarp) tissues to grow and form a berry.  The size of the berry will be…

Rainfall, Frost, Weeds, Spring Diseases, Invasive Pests

As the 2016 El Niño returns after a month hiatus, much progress is being made towards a Drought Recovery. February had only 0.6 inch of rain, but the first two weeks of March brought 5.2 inches of rain, exactly double the long term average. Good rains in January wetted the soil profile well enough to get thorough a dry February, with the possibility of more frequent rains in March as…

ON THE NATURE OF VINEYARDS AND VINEYARD MANAGEMENT

  The wine grape industry, like all of agriculture, is under intensifying pressure from outside.  Increasingly, regulators, retailers, consumers, environmentalists, and others are weighing in on how we conduct our businesses.  While most are well intended, many are ignorant about the true nature, complexity, and requirements of our work and the risks involved.  At the same time, the demands of our work keep us so close to it and overwhelmed…

EVALUATING VINEYARD SOILS IN TRENCHES

We wine grape growers invest great efforts in managing canopies, crops, and other vineyard attributes above ground.  In comparison, our efforts below ground are often nominal.  And yet, the vineyard below ground is essential to the success and long-term viability of our vineyard businesses.  In the vineyard soil lies about 16% to 27% of vine biomass, depending on time of year, and about 43% of stored carbohydrate reserves. And it…

Control of Overwintering Structures of Grapevine Pathogens

Control of Overwintering Structures of Grapevine Pathogens

W. Douglas Gubler, Department of Plant Pathology, University of California, Davis, CA Fungal pathogens of grapevines all produce structures that allow them to overwinter on grapevine cordons, spurs, and canes.  In this way the fungi produce spores the following year that can further cause disease.  For example, grapevine powdery mildew produces a structure called a chasmothecium (cleistothecium) that washes from the leaves in the fall and winter.  They reside on…
