Which of the following practices aids in reducing the risk of phytotoxicity?

Conducting a small test application is a prudent practice that helps in reducing the risk of phytotoxicity. Phytotoxicity refers to the negative effects that pesticides can have on plants, which can manifest as leaf burn, stunted growth, or even plant death. By performing a small test application on a limited area, you can observe the effects of the pesticide on a small scale before applying it to a larger area. This allows you to identify any harmful reactions without risking significant damage to your entire crop or landscape.

This approach is particularly useful for assessing how different plants respond to various pesticides and helps in determining the appropriate concentrations and application methods to minimize potential plant injury. It also provides an opportunity to adjust your strategy based on the test results, ensuring safer and more effective use of pesticides.
