How long can pesticides be applied in the field without a pest control license while in training under supervision?

The correct duration for applying pesticides in the field without a pest control license while in training under supervision is 90 days. This regulation is designed to ensure that trainees gain practical experience and training while still under the oversight of a licensed professional, ensuring safety and compliance with laws regarding pesticide application. During this period, trainees can learn the necessary skills and knowledge to handle pesticides appropriately before obtaining their own license. This approach not only strengthens their understanding of pesticide safety and application but also protects public health and the environment by ensuring that treatments are conducted responsibly.
