VINT A GE 2010 Pests/Diseases: European grapevine moth (Lobesia botrana) was detected and associated quarantine measures put in place; grape mealybug populations tended to be larger than in previous years. Tools/Techniques: Optical berry sorting machines were used by a limited number of growers with much success. Logistics: Labor and harvest machinery demands were great dur- ing a compressed harvest. Monica Cooper Viticulture farm advisor, UC Cooperative Extension SAN JOAQUIN COUNTY Yield across varieties was way down from 2009 (20% to 30%) and below long-term average by 10% to 15%, with the usual exceptions of young vineyards and site variability. Bunch rot was very minimal to nonexistent. Berry and cluster size were on the smaller side, and flower set was variable in weather-sensitive va- rieties such as Merlot. Colors, acids and flavors were excellent— maybe best since 1985. Weather: Above average winter rainfall with slightly delayed bud break. Early spring was wet and cool, and the rest of the season was very cool, dry and windy. Central district caught up, but not new production areas. Pests/Diseases: There was some powdery mildew, but it was minimal with good spray programs. Mites and hoppers were only scattered problems. Vine mealybug continues to spread, while LBAM is an ongoing issue, and EGVM has been found in the area. bw.7.625x4.875.pdf 11/25/08 9:49:55 AM Supply/Demand: Prices are up slightly for Cabernet and Merlot, while other varieties are static or down. There is demand for Mus- cat and Riesling types, and for quality blend-Petit Verdot, etc. Logistics: Regulatory burden and costs are greatly up, especially in labor; input cost up. Varieties: Fruit quality and the consistency of yield for major varieties are this area's big strength. Wines are competitive with good value for consumers; recognition grows. Paul S. Verdegaal Farm advisor, UC Cooperative Extension AND SANTA BARBARA COUNTIES The 2010 season was very challenging for San Luis Obispo and Santa Barbara County growers. Production was about average, but quality suffered due to the lateness of the season and difficulty ripening. Mildew damage, heat and sunburn damage from a September heat wave and rot damage from subsequent rains were all challenging. Fruit harvested before the fall heat and rain was very good, while fruit harvested later was worse. SAN LUIS OBISPO Weather: Winter had abundant rainfall continuing into April. A cool spring led to delayed bud break and growth. Moderate summer temperatures, with severe heat in late September, fol- lowed by damaging rain. Pests/Diseases: Unusually high powdery mildew pressure for the region; mildew problems widespread. Fall rains led to elevated bunch rots in susceptible varieties.
