If pesticides persist in the environment, what may be a direct consequence?

When pesticides persist in the environment, a direct consequence can indeed be the risk of crop injury. Persistent pesticides remain in the soil and water for extended periods, leading to potential buildup in the environment. This buildup can result in unintended exposure of crops to these chemicals, which may cause phytotoxicity—where the pesticide inadvertently damages the plants. Symptoms of crop injury can include stunted growth, leaf curling, discoloration, or even death of the plants.

The persistence of pesticides can also disrupt the natural balance of ecosystems, allowing for the development of resistant pest populations while harming non-target organisms, further jeopardizing crop health. This risk emphasizes the necessity for careful management and application of pesticides to minimize environmental impact and safeguard crop production.
