Whether that translates into a vintner banner year remains to be seen. There is no doubt 2012 will be a solid year.<br /><br />It was encouraging to watch you still pick at modest levels. <br />I will confess widespread disappointment at how many winemakers resorted back to practices of extended hang time and over ripening, pre 2010 & 2011. <br /><br />I had hoped the challenge, but in many ways gifts, of the previous years may have stuck longer, but watched over & over as people picked reds at 28 brix and did huge water & acid adds, or thought Chardonnay just wasn't ripe enough mid Oct at 24-25 brix. <br /><br />Behind the scenes, containers of water, sugar (yes.) etc all in wide use.<br /><br />Clearly many are unable to resist the temptations of extended hang time, for extra 'flavor ripeness' unless forced by nature to do otherwise.<br /><br />Bravo to you, and others like you, that take the gift of a good year and don't abuse it. Lets hope the very slow market shift continues.Two Shepherdshttps://www.blogger.com/profile/13426506978949387662noreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-13606365983390217432012-10-12T09:03:00.240-07:002012-10-12T09:03:00.240-07:00Which portions, if any, of the St. Supéry harvest ...Which portions, if any, of the St. Supéry harvest remain to be completedAnonymousnoreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-34846788427209014552012-08-15T11:32:38.123-07:002012-08-15T11:32:38.123-07:00We are at the end of the second flight of EGVM in ...We are at the end of the second flight of EGVM in the warmer areas of Napa County and so far no moths have been trapped for this generation. There have been a total of 77 moths caught this season in sharp contrast to the 100,000 moths caught in spring of 2010. All of the moths caught this season can be attributed to vineyards that were not treated the previous year. Most of these were from residential or abandoned vineyards. Compliance to treatments for EGVM has been good for 2012 with nearly all growers in the treatment area taking advantage of the subsidized pheromone program, and most growers also applying spray treatments for the first two generations. We should be able to finalize these numbers once all the pesticide use reports have been turned in. <br /> <br />No moths outside of Napa County have been caught yet this season. There is a good possiblity that all previously infested counties will be removed from the quarantine by next year. This will only leave Napa County and neighboring areas of Solano and Sonoma counties still in the quarantine area. We will know by the end of the year what is in store for Napa County after the Technical Working Group submits their recommendations to USDA and CDFA. It is possible that some areas of the county may be targeted for removal from the quarantine at the end of 2013 if they are 3 miles from finds from this season and remain free of EGVM with high density trapping. Isomate pheromone use will probably be curtailed so that detection traps will work to their optimum, but spray treatments will need to be applied for the first two flights next season regardless of the outcome of the TWG recommendations. <br /> <br />Compliance to sanitation and harvest requirements should be followed closely to prevent any spread of EGVM at harvest this season. I have attached a memo from the Napa County Agricultural Commissioners office on compliance and harvest inspections by their office. Their website has information on compliance issues including sanitation, tarping or short-filling of loads, and green waste disposal. Please call them or me if you have questions on these subjects. <br /> <br />Finally, this will be the final EGVM update of 2012. Thank you all for your cooperation and continued efforts to get us to where we are now in this program. We are more confidant then ever that we can get rid of this pest from Napa County but it will depend on your continued vigilance in the future. Please feel free to call me with any questions and good luck with harvest. <br /> <br />Martin Mochizuki<br />Napa County EGVM Grower Liaison<br />707-975-2133<br />707-252-9218 fax<br />martinmoch@sbcglobal.net<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-1795867056321065242012-08-15T11:32:12.301-07:002012-08-15T11:32:12.301-07:00We are in the latter portion of the predicted seco...We are in the latter portion of the predicted second flight of European Grapevine Moth in Napa County and so far no moths have been caught for this flight.

Conventional growers in all areas of the county should have treated or be in the process of treating with Intrepid, Altacor or other larvicides. Organic growers in the warmer areas from Yountville to St. Helena should be treating with their second or third application of BT products or Entrust. Organic growers in the cooler areas such as Carneros, American Canyon, East Napa, or later areas such as Calistoga, Pope Valley, Chiles Valley and hillside vineyards should start treating this week with the first of weekly sprays with BT products or Entrust. All growers should treat for this generation, even if you used pheromones for mating disruption and treated the first generation. Please contact me if you have any questions about the timing, materials, or rates for this application. <br /> <br />Representative from CDFA and the Napa County Agricultural Commissioners office placed pheromone dispensers or stripped fruit in backyard vineyards in the Olive Hill area east of the city of Napa this past week. Also, the Agricultural Commissioners office will be sponsoring three meetings to review the compliance agreements and harvest sanitation requirements for EGVM. All growers, shippers, and wineries should try to attend one of these meetings.

There are still growers who have received Isomate pheromones but have not reported this application on their monthly use reports. It is very important that this information is reported as future considerations for treatment and quarantine areas will be based on these reports.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-2187535864801747652012-07-06T11:55:09.516-07:002012-07-06T11:55:09.516-07:00Two more moths were reported a week ago in the aba...Two more moths were reported a week ago in the abandoned vineyard on Bennett Lane north of Calistoga. This vineyard has since been removed and the vines are piled up to burn. Since this is a later area it is presumed that these moths were still from the first flight of EGVM. So far no moths have been caught yet from the second flight. The total for the first flight of EGVM in Napa County in 2012 was 77 moths compared to 96 in 2011 and 99,000 in 2010. All of the moths caught so far this season were caught near residential vineyards, abandoned vineyards, or in previously uninfested vineyards that were not treated in previous seasons. It is of the utmost importance that all growers treat again for the second generation of EGVM even if you have used pheromones for mating disruption. This will be the last scheduled applications for this season. <br /> <br />If you have not treated yet for the second generation of EGVM larvae this should be done in your next mildew spray application for all conventional growers using Intrepid or Altacor. Growers using other larvicides and organic materials should start treating this week in the warmer areas of Napa county from Yountville to St. Helena. Organic growers in cooler or later areas of the county such as Carneros, American Canyon, East Napa, hillside vineyards, Calistoga, Pope Valley, and Chiles Valley should start their applications the week of July 16th. Organic growers should use a minimum of two applications of BT products or Entrust. <br /> <br />CDFA, in conjunction with Napa County Agricultural Commissioners office, will be conducting public meetings and a neighborhood awareness program in the Olive Hill area to confirm that control measures are being implemented in residential vineyards in that area. <br /> <br />As a reminder , please turn in all spray applications for EGVM in your pesticide use reports.

The predicted egg-laying and egg-hatch of the 2nd generation of European Grapevine Moth in Napa County has been delayed slightly from the original projections due to cooler than normal temperatures. Growers should follow the following timelines for treatment:<br />Warmer areas of Napa County from Yountville to St. Helena-conventional growers using ovicidal/larvicidal materials like Altacor and Intrepid- add materials to next mildew spray. Growers using larvicidal materials including organic growers should start treating the week of July 2nd. Organic growers using Bt products or Entrust should repeat this treatment in 7 days.<br />Cooler areas of Napa County like American Canyon and Carneros, and later areas such as most hillside vineyards, East Napa, Calistoga, and Pope Valley should not start treating with conventional materials until the week of July 9th. Organic growers in these areas should start treating the week of July 16th and repeat BT or Entrust sprays in 7 days. <br />All growers who used pheromones for mating disruption and all growers in the treatment areas of Pope Valley, Chiles Valley, Gordon Valley, and the Howell Mountain and Angwin areas should treat for this second generation of larvae. Please contact me if you have any questions about materials or treatment timing for this application.<br /> <br />The abandoned vineyard on Bennett Lane north of Calistoga will be removed this week through the abatement process by the Napa County Ag. Commissioners office. Residential properties in the Olive Hill Lane area east of Napa will be recontacted later this week by CDFA and Ag. Commisioner's personnel to confirm compliance to treatment procedures. <br /> <br />Please remember to turn in your treatments on your monthly pesticide use reports.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-49393833555019546692012-04-18T19:33:51.770-07:002012-04-18T19:33:51.770-07:00a fantastic tour of Napa Valley~

The flight is projected to start in the cooler areas next week. <br /> <br />Just a reminder to sign and send in all new exhibits to the compliance agreements so the Agricultural Commissioner can update your agreement on their list on the website. If you have not received these new exhibits they are available by calling the Ag. Commissioner at 253-4357 or by downloading them from the website at http://www.countyofnapa.org/AgCommissioner/EGM/ , go to information for growers and wineries and then to the page for compliance agreements. <br /> <br />Now that we are approaching harvest, please be on the alert for any EGVM damage on the clusters. If you or your crews see any evidence of feeding damage from the larvae or an unusual amount of rot associated with larval feeding please take a sample and give me a call or bring it in for identification. We are not anticipating seeing any substantial damage due to the low populations at this point, but it is important to gauge the effectiveness of the program by the amount of damage we might see at harvest. <br /> <br />The Technical Working Group (TWG) will be meeting in December to evaluate the control efforts in the various counties and they will be making recommendations for how we will proceed next year in the deregulation process. <br /> <br />This will be the last weekly update of the season, but I will continue to send out updates if we begin to catch moths or see significant damage from this third flight.

One moth was found in a trap where a few moths were caught earlier on Spring Mountain Rd near Langtry Rd. All growers within 500 meters of the find have treated. This moth was most likely a remnant of the second flight. This brings the total moth count for the second flight to 16. The third(and last) flight of the season is projected by UC Cooperative Extension to start at the end of the month. No more treatments are expected except where there are finds in previously untreated areas.<br /> <br />As a reminder, compliance agreements are required for all growers, wineries,and haulers of grapes in Napa County. Last year's agreements are acceptable this year but they will need to be updated if you are farming new vineyards. Also, the Agricultural Commissioner will be sending out an update to the compliance agreements with a few new addendums. If you do not receive them in the next two weeks please call the Commissioner's office at 253-4357.<br /> <br />All growers who are planning to ship fresh grapes out of the state will need to contact the Commissioner's office so they can start monitoring your vineyard to certify that it is pest free so it can be cleared to ship.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-31002061060978224522011-08-11T14:49:26.861-07:002011-08-11T14:49:26.861-07:008/8/11 update from Martin Mochizuki, Napa County E...8/8/11 update from Martin Mochizuki, Napa County EGVM Grower Liaison<br /><br />The second flight of the European Grapevine Moth has come to an end in Napa county. Projections by UC Cooperative Extension indicate that mid to late instar larvae should be present on the clusters based on the degree day model. So if you have not applied a treatment for this second generation of larvae you can still do so and get effective control. So far in Napa County there have been 15 moths caught during this second flight, and 109 total moths for the first two flights of 2011. In 2010 there were 1284 moths caught in the second generation and over 100,000 total moths at this stage. The third flight of moths for 2011 is expected to start in 2-3 weeks. <br /> <br />Residential treatments are finishing up in some areas of the city of Napa with residences having the option of pheromone treatment or stripping of fruit. <br /> <br />Please remember to turn in all treatments for EGVM to the Agricultural Commissioners office with your pesticide use reports. These reports are critical for future planning by USDA and CDFA for control efforts and subsequent lifting of the quarantine.Juliehttps://www.blogger.com/profile/17141784257745253577noreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-84485234572057535692011-08-02T10:56:46.763-07:002011-08-02T10:56:46.763-07:008/1/11 update from Martin Mochizuki, Napa County E...8/1/11 update from Martin Mochizuki, Napa County EGVM Grower Liaison<br /><br />We are at the end of the second flight of EGVM in Napa County. We caught a few more moths in the Taplin Rd. area east of St. Helena last week. The total for the second flight now stands at 15 from 5 sites. There have been no finds so far from this flight in the previously infested core areas from Yountville to St. Helena, and in the Third avenue/Coombsville area. The total for both the first and second flights for 2011 is 109. Statewide, there have been no other finds so far for this second flight other than in Napa County. Sprays at this time will only be needed if you have not previously treated both generations or there are new finds during this flight. <br /> <br />Residential treatments in Napa, Carneros, and American Canyon are also wrapping up. So far a total of 845 residences have been treated with either pheromones or fruit was stripped from host plants. This has been a very successful program and some valuable lessons have been learned so we can continue the fight in earnest next season in the residential areas. <br /> <br />Maturity sampling for grapes will be handled similar to last season. Fresh samples from infested areas should be in sealed bags, and the winery should dispose of crushed grapes as unfermented green waste. Juice samples are exempt from these restrictions. If clusters or grape berry samples from Napa county are going to a winery not in a quarantined area than they will need a compliance agreement as a receiver of grapes from a quarantined area. Also, if they are going to a private lab for analysis the lab will need state certification.<br /> <br />Please call if you have any questions.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-65615283354702148912011-08-02T10:56:12.096-07:002011-08-02T10:56:12.096-07:007/25/11 update from Martin Mochizuki, Napa County ...7/25/11 update from Martin Mochizuki, Napa County EGVM Grower Liaison<br /><br />We are now past the projected peak of the second flight of EGVM in Napa County and we have not caught any moths in the core infested area from Yountville to St. Helena during this second flight. UC Cooperative Extension monitoring efforts have not turned up any life stages in the last two weeks. However, the state detection traps have caught moths in 2 other locations this week . One area was a previously infested area by Bennett Lane north of Calistoga, and three moths were caught in a new area off of Spring Mountain Rd and Langtry Lane. Growers were informed of the finds and most had already treated for the second generation. Growers in the new area will be treating this week. <br /> <br />If you are in the treatment area (vineyards within 500 meters of a find in 2010 or 2011) and you have not treated yet for the second generation you should do so now. Conventional growers should use Intrepid or Altacor. Organic growers in later areas should be finishing up their second applications for this second generation of larvae. BT products or Entrust should be used for this spray. These should be the last applications of the season for most growers except for vineyards in newly infested areas. <br /> <br />So far we have caught a total of just over 100 moths in the first and second generations of 2011 in Napa County, compared to over 100,000 moths for the first and second generations of 2010. Thanks to eveyone for all your hard work to get us to where we are now.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-7037390285595507610.post-33380491255799973892011-07-19T09:30:51.759-07:002011-07-19T09:30:51.759-07:007/18/11 update from Martin Mochizuki, Napa County ...7/18/11 update from Martin Mochizuki, Napa County EGVM Grower Liaison<br /><br />We have reached the peak of the second flight of EGVM moths in Napa County, and we have still not caught any moths in the state detection traps in the initial infested areas of the county. However, last week four moths were caught in the county. One was in Gordon Valley close to the Solano county line near where one moth was caught earlier during the first flight. In addition, three moths were caught in a previously unifested area off of Green Island Rd in the south part of the county. Growers within 500 meters of these finds were contacted and all have agreed to treat these properties.<br /> <br />If you are in the treatment area (any vineyards within 500 meters of an EGVM find in 2010 or 2011) and you have not treated yet for the second generation of larvae, now is the time to do so. Conventional growers should use Intrepid or Altacor, and organic growers should use BT products or Entrust. Organic growers should apply a minimum of two applications for this second generation about 7 days apart. Please contact your local PCA and winery representatives before applying any materials.<br /> <br />Residential treatments are continuing in Carneros, American Canyon, and parts of the city of Napa. Crews will either be spraying with Dipel, placing pheromone ties or dropping the grape clusters depending on the preference of the homeowner. If you have any questions about these crews working on your properties, reference the name on their badge and call the Agricultural Commissioners office for verification.Anonymousnoreply@blogger.com
