What effect does temperature have on the viscosity of pesticides?

The correct answer is that temperature generally lowers viscosity with increasing temperature. When the temperature rises, the energy of the molecules in a liquid increases, which causes them to move more freely. This increased molecular motion reduces the intermolecular forces that contribute to viscosity, allowing the pesticide to flow more easily. As a result, higher temperatures typically lead to a decrease in the viscosity of liquids, including pesticides, making them easier to spray and apply.

Understanding this principle is critical for aerial application, as lower viscosity can improve the performance of the pesticide by ensuring better atomization and coverage during application. Knowing how temperature influences viscosity can help operators optimize their techniques and achieve more effective pesticide distribution.
