To help reduce pesticide resistance, which practice is recommended?

• A. Use the dosage and amount listed on the label
• B. Use less than the indicated amount
• C. Always use the same class and action in the pesticides applied
• D. Use more frequent applications

Answer: (A)

Using the dosage and amount listed on the label is the best approach to slow pesticide resistance. The label dose is based on research to achieve effective pest kill while minimizing sublethal exposure that can give survivors a chance to carry and spread resistance traits. Underdosing leaves pests alive and selects for those with resistance, making future control harder. Applying more or using the same class repeatedly increases selection pressure and can hasten resistance, plus it wastes product and can raise non-target risks. Following the labeled rate helps maintain efficacy over time and keeps use safer and more predictable.
