Handout from the VVA 2014 meeting #2 (Grape disease updates)

Here is a copy of grape disease updates presentation I have given at the VVA meeting.  (It will open Google Drive, if you find the images to be blurry, please download the file to you computer by clicking "print" icon.  You do not need to sign in to download.)  There are quite a bit of information to cover, so, hopefully this and handout you have in the package would be good companions.  Once again, we will have four IPM workshops throughout the state in the months of February and March.   Please join us.

Luna Tranquility supplemental label for wine grape

There is a supplemental label for the use of Luna Tranquility with wine grape (you can click this link to download.  It will open Google Doc, but you can download via clicking print icon on Google Drive) .  Luna Tranquility is a sister fungicide to Luna Experience.  It has a fluopyram (FRAC group 7 = SDHI, medium risk) mixed with a pyrimethanil (FRAC group 9, the same as Scala).  As a product, it has an efficacy against powdery mildew and Botrytis . ž Application rate is 16-24 fl oz/A, and the maximum usage allowed is 54.7 fl oz/A per season; however, as usual, we recommend not to use it more than twice a season for management of fungicide resistance.  PHI is 7 days, which is shorter than that of Luna Experience (14-days).  It has a 12-h REI, but it does not have the 5-day cane work restriction as Luna Experience has.   We have tested in Winchester in 2013 season, and both Luna Experience (FRAC groups 7 + 3) and Tranquility provided excellent control against Botrytis.   My only co
