Mixing modes of action does what?

Explanation:
Mixing modes of action reduces resistance risk because it forces pests to overcome multiple, different ways to kill them. If only one mechanism is used, a single resistance trait lets some individuals survive and reproduce, spreading that trait quickly. With multiple mechanisms, a pest would need several independent resistance traits to survive all, which is much less likely, so the spread of resistance slows and the efficacy can last longer. It’s important to note this doesn’t guarantee pest elimination, and using products with closely related modes or poor integration can lessen the benefit, so choose genuinely distinct modes and follow label guidance.
