What is the purpose of applying pesticides at the correct application rate?

Applying pesticides at the correct application rate is essential to minimize waste and environmental impact. When pesticides are applied at the appropriate level, it ensures that the amount used is sufficient to manage the pest population effectively without leading to an excess that could contaminate surrounding ecosystems. Over-application can result in run-off, affecting non-target species and potentially harming beneficial insects, soil health, and water quality. Conversely, under-application may not effectively control pests, leading to recurring infestations, which can require additional applications and increase overall chemical use. Thus, following the recommended application rates helps balance effective pest management with the responsibility of protecting the environment.
