Atomization and drift models for spray drift mitigation
| Problem: | Aerial spray operators have been introduced to atomization and drift models, but training on individual use of the models has been limited. The EPA PR notice on product label statements for spray and dust drift mitigation and Arkansas Plant Board regulations have highlighted the need for aerial applicators to use and document applications with droplet spectra classification |
| Objective: | Cooperate in the development of an interactive training module for use in the NAAA PAASS program. |
| Approach: | Survey state and regional aerial applicator associations and determine commonly used aircraft and operational conditions. Develop operational scenarios with USDA ARS atomization models and the AgDRIFT model for interactive presentation. Participate in train-the-trainer sessions for PAASS presenters |
|
Significant Impact: |
A 2-hour PowerPoint presentation was developed for the 2002-2003 PAASS program to introduce the models and their utility to aerial applicators. Arkansas and Kansas Extension Specialists have agreed to cooperate in development of the 2003-2004 training module. The NAAA PAASS Director and NAAREF PAASS Program Committee have offered travel support as needed for the project. Printed material could include the Spray Nozzle Handbook if ARS publishes the document by fall 2003. |
