What is one potential downside of relying solely on chemical control?

Relying solely on chemical control can lead to significant ecological issues, particularly the development of pesticide resistance in pest populations. When a single chemical is used repeatedly, the pests may adapt to it over time, resulting in a situation where the chemical becomes ineffective. This resistance can escalate the pest problem, requiring stronger or more toxic chemicals to achieve the same level of control.

Additionally, the use of chemical controls can inadvertently harm beneficial organisms, such as pollinators, predators of pest species, and microorganisms that contribute to soil health. This not only disrupts the ecosystem but can also lead to secondary pest outbreaks, as the natural controls provided by these beneficial organisms are diminished.

In contrast to other choices, which either highlight benefits that do not stem from sole reliance on chemical methods or misrepresent the complexities of pest management, the downside associated with pesticide resistance and harm to beneficial organisms underscores the importance of integrated pest management (IPM) strategies. Integrating various pest management techniques can help mitigate these risks while promoting sustainable practices in horticulture.
