What is the potential risk of using systemic pesticides?

• A. Their immediate effectiveness
• B. Their toxicity to humans
• C. They can affect non-target pests that consume treated plants
• D. They are not biodegradable

Answer: (C)

Systemic pesticides are designed to be absorbed by plants and transported throughout their tissues. This property allows them to effectively target pests that feed on the plant, such as insects, by making the entire plant toxic to them. However, this same characteristic can pose a significant risk because non-target organisms, including beneficial insects, wildlife, or even pets that consume parts of treated plants, can also be affected. For instance, a ladybug that feeds on aphids on a treated plant may inadvertently ingest the pesticide, leading to harmful effects on its health. This risk emphasizes the importance of careful application and consideration of the surrounding ecological environment when using systemic pesticides, as they can unintentionally harm organisms that were not the intended targets of the treatment.
