What can applicators do to make spray droplets heavier and reduce the likelihood of drift?

Close all building windows near the application site
Choose low-volatility products
Apply products on hot days
Use adjuvants

The correct answer is: Use adjuvants

Applicators can use adjuvants to make spray droplets heavier and reduce the likelihood of drift. Adjuvants are chemicals that are added to spray solutions to modify the physical properties of the spray droplets, making them larger and more uniform in size. This increases the weight of the droplets and reduces the chances of them being carried away by wind, which results in less drift. Options A, B, and C are incorrect because they do not directly address the issue of droplet size and weight. Closing building windows may reduce the exposure of non-target organisms to the spray, but it does not affect droplet size. Choosing low-volatility products may reduce the volatility of the chemicals in the spray, but it does not impact the weight of the droplets. Applying products on hot days may increase evaporation, but it does not necessarily make the droplets heavier. Adjuvants are the most effective option for controlling droplet size and reducing drift.
