Why is it important to monitor soil moisture levels before pesticide application?

Monitoring soil moisture levels before pesticide application is crucial for ensuring optimal efficacy and reducing runoff. If the soil is too dry, pesticides may not be absorbed effectively by the plants or the soil, leading to diminished effectiveness of the pesticide treatment. On the other hand, if the soil is overly saturated, there is a higher risk of runoff, which can lead to potential contamination of nearby water bodies and can reduce the pesticide's effectiveness.

Understanding soil moisture levels allows for better timing and method of application, which is essential for maximizing the benefits of the pesticide while minimizing harmful environmental impacts. The application made under optimal moisture conditions can help ensure that the pesticide targets the intended pests more effectively and reduces waste and environmental risks.
