How is a selective pesticide defined?

• A. Effective against multiple types of pests
• B. Effective against one organism but not another
• C. Pesticides used only in agriculture
• D. Always organic in nature

Answer: (B)

A selective pesticide is defined as one that targets specific organisms while leaving others unharmed. This targeted approach allows for the management of pest populations without disrupting non-target species, such as beneficial insects, plants, or animals. For example, a selective herbicide may kill certain types of weeds while remaining safe for the surrounding crops, which is crucial for maintaining ecological balance and promoting sustainable agriculture. Selective pesticides are essential in integrated pest management (IPM) strategies, where the goal is to manage pests effectively while minimizing negative impacts on the environment and non-target species. This is in contrast to non-selective pesticides that indiscriminately affect a wide range of organisms, which can lead to broader ecological consequences. Understanding this distinction helps pesticide applicators choose appropriate products for their specific pest control needs.
