Which of the following reduces pesticide use in landscaping?

Accurate pest identification is crucial in reducing pesticide use in landscaping. When a landscape contractor can correctly identify the pests affecting plants, they can determine the most appropriate and targeted control measures. This can involve selecting biological controls, using less harmful pesticides, or even implementing cultural practices that mitigate pest pressure without resorting to extensive chemical use.

Inaccurate pest identification could lead to unnecessary pesticide applications, which not only pose risks to the environment but also contribute to the development of pesticide resistance among pests. By knowing precisely which pests are present, landscape professionals can make informed decisions that enhance the health of the ecosystem, promote beneficial insect populations, and reduce reliance on chemical treatments.

The other options would likely lead to increased pesticide use rather than minimizing it. Improper plant selection can create environments more susceptible to pest infestations, while ignoring soil conditions can contribute to unhealthy plants that attract pests. Overwatering can stress plants and make them more vulnerable to infestations, potentially leading to increased pesticide applications.
