Texas Pesticide Applicator Practice Exam

True or False: You can still apply the wrong amount of pesticide even when you have the right mixture in your spray tank.

1. True

2. False

3. Depends on the pesticide

4. Only if mixed improperly

The correct answer is: True

The statement that you can still apply the wrong amount of pesticide even when you have the right mixture in your spray tank is true. This highlights the distinction between the proper formulation of the pesticide and the volume or rate at which it is being applied. Having the right mixture means that the pesticide is combined with water or other carriers in the correct proportions, which is critical for ensuring efficacy and minimizing harm to the environment and non-target organisms. However, even with the correct mixture, if the applicator does not adhere to the recommended application rate—either by using too much or too little—the results can be detrimental. Applying too high a concentration can lead to phytotoxicity, harming plants and the surrounding ecosystem, while too low a concentration may not effectively control the target pests, causing ineffective treatment. In practice, it’s essential to follow the label instructions, which specify both the appropriate mixture and the correct application rate to achieve desired results without adverse effects.
