Which practice contributes to sustainable pest management?

Promoting biodiversity within the agro-ecosystem is a key practice that contributes to sustainable pest management. Biodiversity enhances ecosystem stability and resilience, making it more difficult for pest populations to proliferate unchecked. A diverse array of plants and animals can naturally control pest populations through predation and competition, reducing the need for chemical interventions. Additionally, a diverse environment can provide habitats for beneficial organisms, such as natural predators and pollinators, which further supports ecological balance.

In contrast, the other options do not align with the principles of sustainable pest management. Relying exclusively on pesticides can lead to resistance in pest populations and harm beneficial organisms. Planting a single crop species can create vulnerabilities, as it may not support a diverse range of natural pest controls. Finally, using only chemical controls ignores integrated approaches that utilize biological and cultural strategies, which can be more effective and environmentally friendly in managing pest issues.
