Desired Changes

Participants will learn from one of the world’s leading experts of vineyard spraying technology how to increase the efficacy of their sprayer applications.

Participants will take what they have learned and the “Effective Vineyard Spraying “ book they received as a guide to improve their vineyard spray applications and/or educate others of these techniques.

Participants will use this information to apply or teach others to apply pesticides with greater efficacy, greater personal safety and with less off-site drift and impact.

(Why is it important to address this issue with education? What are the desired changes?)

The commercial winegrape vineyard industry is still relatively young in Iowa and the Midwest. Many if not most of these vineyard operators have not had any hands-on formal training withairblast sprayer calibration, operation or use. Many do not have the correct  equipment needed and/or their equipment is not set up correctly.

Learning of and following effective pesticide sprayer operation fundamentals produces more profit and safety for the operator with less impact on the environment.

(Outputs: activities, numbers reached, publications, products)

Thirty two participants attended this workshop. They were composed of Extension educators, junior college educators, researchers, winery owners and vineyard operators.  They came from Iowa, Minnesota, South Dakota, Nebraska and Missouri to attend this workshop.  Each participant walked away with a copy of Dr. Andrew Landers book – “ Effective Vineyard Spraying” .  Half of this full day workshop was composed of classroom training and half was composed of actual hands-on equipment demonstrations.

RESULTS(Outcomes:  specific changes that occurred in Learning, Actions,Conditions; how outcomes were measured)

Twenty three of the participants filled out the after meeting evaluation. Three of these participants intended to buy new or replace the sprayer equipment they currently have because of this workshop.  When asked to rate the workshop (1- poor to 5 excellent), they rated the personal economic value of the workshop as 4.87 and the overall workshop rating as 4.78. 

Here were the comments when asked “what was the most important thing they learned today”:
- Everything,
- Nozzle selection
- Sprayer calibration& adjustment,
- Air & water management. Can probably get by with less of each.
  Thinking about going from air shear to regulated nozzle.
- That I have a cheap sprayer
- Boom sprayers may make a comeback. Air induction spray tips.
- Protection; Industry standpoint what’s out there. How to spray
correctly, creative ways to spray. More than anything – need to
keep on learning.
- Learning more about diff nozzle & a big refresher on all phases of
   spraying excellent workshop – ex. Speaker (presentation)
- All excellent
- Too many to list
- Latest sprayer technology
- Nozzles, air speed, mixing of spray
- Spraying Tech – nozzles
- Spray Pattern Determination
- use of CF Valve. Actually many valuable items.
- Better, more efficient way to calibrate and spray
- Complexity of vineyard spraying. Good science available to grape
- The need for and process of accomplishing variable application.
   Protect the environment. Economic benefit.
- Importance of droplet size for differential targets

Public Value (now or future)
(Impact:  Who benefits beyond participants and how?  What conditions changed?)

It is not unusual for a Midwest commercial vineyard to make 8-12 pesticide applications per season.  Wine grapes are a VERY pesticide use intensive crop.  Learning to apply these pesticides correctly saves money for the grower, reduces the pesticide health risks, protects a valuable crop and reduces the impact on the environment.
