What is the primary goal of applying a fungicide?

The primary goal of applying a fungicide is to prevent or control fungal infections in plants. Fungicides are specifically designed to target fungal pathogens that can cause various diseases, negatively impacting plants' overall health and development. By using fungicides, growers can protect their crops from diseases such as powdery mildew, rust, and blight, which can lead to significant yield losses if left untreated.

While enhancing plant growth, repelling insect pests, and improving soil health are essential components of overall plant care, they are not the primary objectives of fungicides. The formulation and application of these chemicals focus solely on managing issues related to fungal pathogens, making option B the most accurate choice in this context.
