What is an example of a practice LEAF promotes for pest control?

Biological control methods are a key practice promoted by LEAF for pest control due to their focus on sustainable and environmentally friendly approaches. This method involves the use of natural predators, parasites, or pathogens to manage pest populations. By harnessing the natural ecosystem, biological control helps to maintain pest levels below damaging thresholds without the heavy reliance on synthetic chemicals, which can have harmful effects on the environment and human health.

In contrast, heavy pesticide application tends to lead to increased resistance in pests and can harm non-target organisms, including beneficial insects. Burning pest-infested crops is a more destructive method that can lead to soil degradation and loss of fertility. Lastly, dependence on genetically modified organisms may not align with LEAF's emphasis on sustainable agriculture practices, as it can lead to reduced biodiversity and environmental concerns related to monocultures.
