What does the term biopesticide refer to?

The term biopesticide refers to pesticides derived from natural materials, such as plants, bacteria, fungi, and other biological sources. These substances are designed to target specific pests or pathogens while minimizing impact on non-target organisms and the environment. The natural origin of biopesticides often makes them a more environmentally friendly alternative to conventional synthetic pesticides, which are created from chemical processes.

Biopesticides typically include microbial pesticides, which are based on living microorganisms, and plant-incorporated protectants, which are substances produced by plants themselves. By utilizing naturally occurring substances, biopesticides can offer effective pest control with a reduced risk of resistance development in pest populations and decreased toxicity to beneficial organisms.

Other options describing synthetic pesticides, limitations on effectiveness, or broad-spectrum applications do not accurately capture the essence of biopesticides, which is their derivation from natural materials.
