Handouts from recent IPM workshops

Thanks again for those of you who were able to attend IPM workshops.  I hope you enjoyed the meetings, and if you have any suggestions or comments, please do not hesitate to contact me.

Here are copy of fungicide updates and interactive fungicide planning presentations.

2016 Fungicide updates
(Please note: I just learned that Luna Tranquility won't be available for grape...  Too bad since it would be a good material for Botrytis management.  We still have Luna Experience, but there will be a label language change for grape.  I will post it once I learn more about it.)

Interactive fungicide planning.

Also, I think many of you have already participated, but there is a survey for evaluation of my Extension activities.  If you could spend 3-4 min of your time to answer it, I would greatly appreciate. (This is the same as the one Tremain sent out and I distributed at the VVA and other meetings.)


This is a questionnaire to help evaluate impact of the grape pathology extension program of Dr. Mizuho Nita at the AHS Jr. Agricultural Research and Extension Center. We would like to gauge the public value of this work and to help identify areas that to strengthen. We greatly appreciate your time and input here in determining if and how these research and educational programs have benefited your business. The survey is anonymous.

Two IPM workshops and two webinars

There are several extension activities in the next few weeks that you maybe interested in.

1) IPM workshop at Early Mountain Vineyards
This will be a full day IPM workshop to cover viticulture, entomology, weed science, plant pathology, and legal and safety updates. This will count towards VA private pesticide applicator license hours (full credit for category 90).

Date: Feb. 16th 2016.
 
Agenda
9:30 Introduction and overview of workshop 
9:45 Viticulture updates – Tony Wolf
10:15 Worker Protection Standards- Roberto Quintero
11:00 Entomology updates - Doug Pfeiffer
11:45 Weed science updates - Jeff Derr
12:30 Lunch (please bring a lunch)
13:15 Laws and regulations - Roberto Quintero
14:15 Pathology Updates- Mizuho Nita
15:00 Interactive Scheduling – in teams
16:00 Meeting Adjourns
 
2) Interactive Integrated Grape Disease Management workshop at Dobson, NC
This will be a half-day IPM workshop that focus on grape disease management and legal and safety updates. This will also count towards your private pesticide applicator license hours.
Title: Interactive Integrated Grape Disease Management Workshop 

Date and time: February 18 from 1-5 pm Location: NC Cooperative Extension, Surry Center, 210 North Main Street, Dobson, NC 27017. 

Mizuho Nita, Assistant Professor and Grape Pathology Extension Specialist, AHS AREC, Virginia Tech Joanna Radford, NC cooperative Extension agent 
 
In this workshop, audiences will participate on a development of a full season grape disease management plan. This will be hands-on workshop with a lot of interactions. Items to be discussed are: integrated pest/disease management, fungicide resistance (FRAC code, rotation, etc.), and biology and management strategies for key diseases at each grape growth stages, from dormant to after harvest. At the end of the workshop, we will develop a mock-up plan(s) for a season, and critique as a group. This will count toward four hours of NC pesticide credits – categories N,O,D,X.  Also, full credit for VA category 90.

Agenda
1:00 PM - 1:10 PM Introduction
1:10 PM- 1:40 PM  Safety and legal updates (Joanna Radford)
1:40-3:20 PM Grape pathology, fungicide updates (Mizuho Nita)
3:30-4:45 PM Interactive fungal disease management planning (Mizuho Nita)
5:00 PM Discussion and adjourn
 

3) Webinar on clean plants for the eastern wine and grape industry
How the National Clean Plant Network, new testing protocols and a revitalized NY certification program will reduce the risk of nursery-transmitted viral pathogens.

Time: Thursdays at Noon (Eastern Time). March 10, 17, 24, and 31.

Since 2008, National Clean Plant Network Centers have joined together to efficiently produce, maintain, and distribute healthy grapevine budwood to the industry.  These materials are starting to make their way to nurseries, and ultimately, to end-users.  This four-part webinar series will cover the process of producing and distributing virus-tested plant material, graft-transmissible diseases and their impact, New York State’s new testing and certification program, and New York nurseries’ investment in new motherblocks and propagation procedures.

March 10: The Pipeline:  From tissue culture to your vineyard.
Joshua Puckett, FPS, UC Davis and Tim Martinson, Cornell University
March 17: Viral diseases transmitted through nursery stock in the East: Grapevine Leafroll Disease, Tomato Ringspot, and Grapevine Red Blotch
Marc Fuchs, Cornell University; Annemiek Schilder, Michigan State University; and Mizuho Nita, Virginia Tech
March 24: Crown gall biology and management; Value of virus-tested plant material.
Tom Burr, Cornell University and Shadi Atallah, University of New Hampshire
March 31: New York’s revitalized grapevine certification program, and New York nurseries’ plans for the future
Marc Fuchs, Cornell University; Margaret Kelly, NYS Department of Ag and Markets; Dennis Rak, Double A Vineyards; Eric Amberg, Grafted Grape Nursery; Fred Merwarth, Hermann Weimer Nursery

 4) Webinar on grapevine red blotch disease
 
Grapevine Red Blotch Disease: What You Need to Know


Friday, February 26, 2016
 
Summary:

Grapevine red blotch disease and the virus associated with it has been confirmed in many major grape production regions of the United States and Canada. Since the identification of the virus in 2011, several teams of researchers from across North America have been intensely characterizing the disease and effects on grapevines, as well as characterizing the virus, its spread, and potential management. Considerable progress has been made, but much remains unknown. Speakers representing many of these labs will be presenting their work and what it means for the grape industry. For more information, please contact Frank Zalom at fgzalom@ucdavis.edu . (or visit their registration page)

Handouts from 2016 VVA meeting

Here are handouts from my presentations from the VVA meeting.

1) Slides from "Interactive Grape Disease Management Workshop"
2) Results from the "planning session". Please note that this is the results of answers from randomly selected people, and I am providing this as a note from the workshop.  Although it looks "OK", this is not what we recommend.
3) Slides from "Biology and Management of Grapevine Crown Gall"

It was very nice to see you all at the meeting.  As usual, I really enjoy talking to all of you!

If you have missed the VVA, there will be two meetings that we will host:
1) IPM workshop at Early Mountain Vineyards on 16 Feb from 9:30 AM
2) Interactive grape disease management workshop at Surry county Extension Center (210 North Main St., Dobson, NC 27017) on 18 Feb from 1:00 PM.

I will post details of these meeting in a few days.
