Reducing Spray Drift – A Crash Course

Click here to read more about reducing spray drift.sprayer

Drift reduction is an ever increasing priority in pesticide applications. Education on new technology and principles of drift reduction is a focus of TPSA and was a key topic at the 2016 TPSA Annual Conference. Below are highlights from conference presentations that provided information on some of the fundamental factors influencing drift potential and steps that can be taken to prevent off-target movement.

1. Forces acting on spray droplets: wind speed – gravity – evaporation – temperature inversions
Many forces can impact spray droplet movement, including:

  • Wind speed – the stronger the wind current the more likely drift will occur.
  • Gravity impacts the direction of falling droplets, goal is downward to crop.
  • Evaporation causes droplets to shrink making them more susceptible to off-target movement. Smaller droplets are more likely to drift.
  • Temperature inversions (still air with near zero wind speed) limits dispersion and allows small droplets to “hang” in a cloud, slowly moving across the landscape.

2. Droplet size
Droplet size is very important to ensuring the application reaches the target. Smaller droplets are more likely to be impacted by air drag, moving along with transient wind currents. The American Society of Agricultural and Biological Engineers (ASABE) have standards by which every nozzle is rated and droplet size is classified.

3. Nozzle Selection
Nozzle selection is an important part of the spray application. To avoid drift, applicators will need to replace conventional nozzles with nozzles engineered to reduce drift. This includes selecting nozzles capable of producing larger droplet sizes but still maintaining appropriate spray coverage. Selecting nozzles with spray droplet sizes that are medium (M) and larger, as classified and recommended by ASABE, will help prevent off-target movement. Specific recommendations depend on product and application conditions and can be guided by the pesticide label. Pressure, Spacing, Volume, and Speed are also factors in nozzle selection.

4. Drift reduction and deposition aid adjuvants
Drift reduction agents can influence droplet size and stability and reduce off-target movement of pesticides. Thicker solutions tend to increase the number of large droplets while decreasing small droplet production in the spray spectrum.
The objectives of adjuvants used for drift reduction are to:

  • increase active ingredient deposition on the target
  • improve spreading, sticking, and penetration capabilities of the active ingredient
  • thicken the spray solution and reduce the incidence of driftable fine spray particles

Applicators still need to follow all recommendations: avoid spraying in high winds, adjusting boom height, and using drift reducing nozzles. For best practices, keep in mind the use of a drift reduction adjuvant is a single step in the drift reduction process.

5. Weed resistance triggers need for additional site of action herbicides
Increases in the development and distribution of glyphosate-resistant weeds have necessitated the need for additional herbicides with different sites of action. The new, pending herbicide-seed technologies that include synthetic auxin products pose both physical drift and vapor drift concerns.

Gas Cylinder Assessment & Management Training – Videos and Presentationsgas-cylinders

Three sessions dedicated to Gas Cylinder Assessment & Management Training were presented by Jeff Gold of Integrated Environmental Services, covering Gas Cylinder Anatomy, Assessment and Management Processes. The session presentations are included on the TPSA site in the Members dropdown menu under Member Area. Access is limited to TPSA Members.
camera Video versions – The Gas Cylinder sessions are also being produced as a package of four videos. Two are complete at this time and are also posted on the TPSA site in the Members drop-down menu under the TPSA members-only Member Area.


Worker Protection Standard (WPS) & International Center for Personal Protective Equipment (ICPPE)

WPS – Information on current and new revisions in the January 2016 updated EPA Worker Protection Standard was presented. Included in the sessions was a panel discussion on resources needed and steps necessary to educate individuals and businesses on the new requirements. Personal protective equipment for pesticide applicators, spray drift label language, and use issues were also covered.

Mini-Bulk Containers Cleaning, Recycling and Trackingtank1

Encouraging the cleaning and recycling of Mini-Bulk and IBC containers has been a TPSA goal for many years, in particular caged tanks as they have the most value in post-use. Several presentations were made in pursuit of this TPSA goal.  pdf_icon IFCA – Mini-Bulk Recycling Project – David Stengl

Benefits of Participating in TPSA – Member Perspectives

Paul Derig – J. R. Simplot – Environmental Health and Safety Manager
Why TPSA? It is the only forum that I have found where Academia, Government, and Industry can have on par discussions and input around best management practices, current and future regulations, as well as communications, across the spectrum of pesticide stewardship.
 

Allan Hovis – Bayer CropScience – Director Stewardship/State Affairs – retired
TPSA was one of the highlights of my career over the last 15 years. I can easily say I got way more out of TPSA then I ever put in. I will miss it.

 

 

Jeffrey Rogers, Virginia Department of Agriculture and Consumer Services
Our membership in TPSA and attendance at the annual conferences has totally changed the way that we do business in Virginia. Between participation in the sessions and the business contacts made, our processes and contracts have improved and we have seen dramatic growth in our program areas.

acrc-image10,440,000 pounds of pesticide containers recycled in 2015
TPSA sponsor ACRC achieved a new record for recycling pesticide containers of 55 gallons or less. In 2015, 10,440,000 pounds of pesticide containers were collected and recycled in the USA under the auspices of the industry funded ACRC, representing a 4% increase over 2014. This record marks the sixth year in a row that pesticide container recycling exceeded eight million pounds. Since 1993, over 163 million pounds of pesticide containers have been collected and recycled.
