5 Tips for reducing spray drift

One of the major problems challenging pesticide applicators is spray drift. Spray drift not only results in wasting expensive pesticides and pollution of the environment, it may damage non-target crops nearby, and poses a serious health risk to people living in areas where drift is occurring. 

Although complete elimination of spray drift is impossible, problems can be reduced significantly if you are aware of major factors that influence drift, and take precautions to minimize their influence on off-target movement of droplets. The factors that play a role in either the creation, or reduction of spray drift are: a) Spray characteristics, such as volatility and viscosity of pesticide formulation; b) Equipment and application techniques used for spraying pesticides; c) Weather conditions at the time of application (wind speed and direction, temperature, relative humidity and stability of air around the application site); and most importantly, d) Operator care, attitude and skill. Here are five cost-effective tips on how to minimize spray drift.

1. If you can, keep your nozzles as close to the target as possible while still producing a uniform distribution of spray on the target. This doesn’t cost any money as long as it is practical to make it happen.

2. When you’re ready to change nozzles, consider selecting nozzles that produce much fewer of the extremely small droplets that are most likely to drift away. Low-drift nozzles are in the market and do a tremendous job of eliminating extremely small, drift-prone droplets from the droplet spectrum.

3. There are chemicals sold in the market that are designed to increase the droplet size, and reduce the number of very small droplets when added into the spray mixture. Most of them are some sort of polymer that tends to increase the viscosity and density of the spray mixture, which leads to larger droplets. This, however, should be the last defense against drift. First consider the other option such as better targeting of the spray and switching to low-drift nozzles.

4. Use shields that cover partially or fully the distance between the target and the nozzles. There are companies manufacturing and selling such attachments to the boom. Shields prevent small droplets from moving away from the immediate application area. This, however may not be practical for sprayers with extremely large booms.

5. If there are any doubts about a spraying job that might result in drift, wait until there is no longer that element of doubt. Always pay attention to wind direction and magnitude. The best investment you can make is to buy a wind meter that tells you how high the wind velocity is at any given time. Having a wind meter handy will help you avoid a costly problem associated with spray drift.

More detailed discussion on these tips and other drift reduction strategies are outlined in following OSUE Extension Fact Sheets available online:

Actual User Testimonial:

"Last year (2013) after I installed my new "blockage monitor," it worked fine in the yard & was ready to go to the field. So when I got to the field, my very first pass the monitor went off telling me I had a blockage, I couldn't believe I could have a problem so soon, sure enough, I had an orifice plugged, I may have planted all day before checking flow again. So I unclogged the orifice & got back to planting, this time assured I was getting fertilizer to every row.

"The potential loss of crop from not having fertilizer to each row is just too great... now I have peace of mind."

8 Management Practices For Spray Drift Control

Dr. Robert Wolf, Wolf Consulting & Research, LLC, Mahomet, IL, is one of the leading experts in drift management strategies. The past few years, Wolf has spent much of his time conducting the On Target Application Academy (with cooperation from TeeJet Technologies and BASF). 

In his training, Wolf offers a list of drift management strategies that he works from. Thus, here are eight best management practices applicators should follow to manage spray drift, according to Wolf.

  1. Nozzle Selection: The key with nozzle selection is finding a balance between drift reduction and maintaining maximum product efficacy.
  2. Use Lower Pressure: Wolf advises that using a drift reduction nozzle at low pressure (30-40 psi) can result in uneven spray patterns/coverage and recommends using air induction nozzles at pressures between 50-80 psi.
  3. Increase Flow Rates: The problem with using less water in applications is that it typically results in smaller, more drift-prone spray droplets.
  4. Lower The Boom Height: Wolf recommends applicators get their boom heights down to 24 inches, which he says “goes a long way toward reducing drift.”
  5. Watch Application Speeds: Wolf says many applicators are unaware that higher application speeds require higher pressure to deliver the correct volume.
  6. Avoid Adverse Weather Conditions: Wolf says an applicators best option is always to choose to not spray when environmental conditions are not favorable.
  7. Use Buffer Zones: The increase in different herbicides, coupled with label requirements, in the near future will make these more important for applicators to achieve proper on-target work. However, size could be an issue.
  8. Consider Other Technology Solutions: According to Wolf this could include the use of shields, air-assist or pulse-width modulation or drift reduction additives such as adjuvants.
