Which method can be used to control pest populations organically?

Using natural predators to control pest populations is a fundamental method of organic pest management. This biological control strategy involves the introduction or encouragement of natural enemies, such as insects, birds, or other creatures, that prey on the pests. By maintaining a balance in the ecosystem, these natural predators can help keep pest populations in check without the adverse effects associated with synthetic chemicals.

This method promotes biodiversity and can reduce reliance on chemical interventions, which can have harmful impacts on non-target species and the environment. Natural predators are often considered a sustainable approach, as they work within the ecosystem to manage pest populations, encouraging healthier agricultural practices.

In contrast, the other methods involve chemical or modified organisms that do not align with organic management principles. Broad-spectrum chemicals and highly toxic pesticides can harm beneficial organisms and disrupt ecosystems, while genetically modified organisms might not be considered organic due to the alterations made at the genetic level. Thus, the use of natural predators stands out as a preferred organic method for controlling pest populations.
