Which of the following statements about pesticides is true?

The statement that some pesticides can be beneficial for crops is accurate because it highlights the role of pesticides in pest management and crop protection. Pesticides, which include herbicides, insecticides, and fungicides, are designed to target specific pests that threaten plant health and agricultural yield. When used correctly and responsibly, these substances can effectively control harmful organisms that damage crops, thereby improving agricultural productivity and ensuring food security.

This benefit is also tied to integrated pest management practices, where the use of pesticides is balanced with other methods, such as biological control and crop rotation, to minimize harm to non-target organisms and the environment.

In contrast, the other statements present misconceptions about pesticides. The notion that all pesticides are harmless to humans overlooks the potential risks and health impacts associated with improper use or exposure. Similarly, claiming that all pesticides are toxic to all organisms fails to consider the selective nature of many pesticides, as they are formulated to affect specific pests while being less harmful to other organisms. Lastly, suggesting that pesticides are only used for agricultural purposes disregards their application in various settings, including residential areas, public health, and landscaping, where they can also serve vital roles in controlling pests.
