The function of photosynthetic inhibitors in pest management is primarily to prevent photosynthesis, which leads to rapid wilting of the plants. These chemicals disrupt the photosynthetic process by targeting key components involved in light absorption and energy conversion within plant cells. As a result, the affected plants are unable to produce the necessary energy and building blocks needed for growth and survival. This ultimately causes the plants to wilt and die, which can be an effective strategy in managing certain pest populations by eliminating the host plants they rely on for food and habitat.

The other options describe functions that are not aligned with the purpose of photosynthetic inhibitors in pest management. Enhancing photosynthesis or facilitating faster growth would work against the intended effect of controlling pest populations, while improving soil health does not relate to the direct action of these inhibitors.
