What are biorational insecticides derived from?

Biorational insecticides are derived from biological or natural origins, which is what makes them a key part of integrated pest management strategies. Unlike conventional synthetic insecticides that may have broad-spectrum effects and can harm beneficial organisms, biorational insecticides are usually designed to target specific pests while minimizing impacts on non-target species, including beneficial insects, humans, and the environment.

These products often include insecticidal substances derived from plants, microorganisms, or naturally occurring compounds that have low toxicity and environmental persistence. This approach not only aligns with ecological principles by promoting biodiversity but also offers a way to manage pest populations sustainably.

The other options relate to sources of pesticides that typically do not fall under the biorational category. Synthetic compounds are human-made and can have negative effects on the ecosystem. Petroleum-based products are also synthetic and can lead to severe environmental and health risks. Meanwhile, mineral sources often refer to inorganic pesticides, which do not fit the biorational classification as they are not derived from biological or natural origins.
