EUROPEAN GRAPEVINE MOTH 1ST GENERATION TREATMENT RECOMMENDATIONS

 

Now is the time to treat for the 1st generation of the European Grapevine Moth (EGVM) if you have yet to do so. Growers within 500 meters of a find in 2011, 2012 or 2013 are encouraged to follow the treatment protocol below.   Pheromone distribution for mating disruption for select areas around 2013 finds is still planned and individual growers will be notified to pick up their Isomate ties at the Agricultural Commissioner's office. It is important for the County that all sprays for EGVM be reported at your earliest convenience on your pesticide use reports.

 

1st GENERATION EGVM treatment protocol

·         The optimal time to treat the 1st generation with conventional and organic products is just prior to the beginning of bloom.  Growers should use the flower cluster as an indicator for this treatment timing. At the optimal treatment timing, the flower cluster will be fully expanded, with the individual flowers separating.

·         Growers using conventional products should only need to treat once if applied at the optimal time

·         Organic growers should begin treatment during this optimal time and continue through egg hatch and early larval development (typically 3 applications at 7-10 day intervals)  

·         Conventional and organic treatments are considered late if the vines in the block are in full bloom.  If this is your scenario, please start your insecticide spray applications immediately.

·         Conventional and organic treatments are considered early if the applications occurred more than 14 days before 1% bloom.  If this scenario occurs, conventional growers should consider retreating and organic growers adding one treatment for the 1st generation.

Vine development varies by region, variety and block, so please follow your vineyard development closely to ensure you are timing your insecticide applications appropriately.  Click here for relevant EGVM photos and to read the complete UCCE 2012-2013 treatment recommendation.
