Is it true or false that pesticide resistance is limited to one active ingredient?

Pesticide resistance is a phenomenon that occurs when a pest population becomes less sensitive to a specific pesticide over time, making the pesticide less effective against that pest. The key aspect of this resistance is that it is not confined to just one active ingredient. When a pest develops resistance to an active ingredient, it can also exhibit cross-resistance to other pesticides that share similar modes of action, meaning that the efficacy of multiple related active ingredients can be compromised.

Additionally, resistance mechanisms can vary based on pest species and environmental factors, but the overall concept remains that resistance can transcend individual products. This means that if proper management strategies are not implemented, such as rotating different modes of action or using integrated pest management practices, resistance can spread to other chemicals as well. Therefore, the assertion that pesticide resistance is limited to one active ingredient is incorrect, leading to the conclusion that the answer is false.
