What application method is generally used for insecticides?

The application of insecticides can be accomplished through various methods, each suited to different situations and target pests. Foliar application involves spraying the insecticide directly onto the plant leaves, allowing for quick absorption and effectiveness against pests that feed on foliage. Soil application involves applying the insecticide to the soil where it can target root-feeding insects or be taken up by plants for systemic activity. Granular application refers to the use of solid insecticide granules that can be spread over the soil, providing controlled release and targeting pests in the soil or at the plant's base.

All of these methods—foliar, soil, and granular application—are commonly used in pest management, depending on the pest's life cycle, the type of insecticide used, and the specific crop or environment. Therefore, recognizing that each of these methods has its advantages, a comprehensive approach employs multiple application methods to enhance effectiveness and achieve better pest control results.
