Thiamethoxam can be applied in various ways depending on the target pests and the crop being treated. Here are some common application methods for thiamethoxam:

1. Foliar application: Thiamethoxam can be applied as a foliar spray, where it is mixed with water or a suitable carrier and sprayed onto the foliage of the target crops. This method is commonly used to control chewing and sucking insects present on the leaves and stems. The application rate and timing may vary depending on the specific pest and crop being treated.

2. Soil application: Thiamethoxam can also be applied to the soil, either as a granule or as a liquid formulation. Soil applications are typically used to control soil-dwelling pests such as termites, wireworms, and grubs. The pesticide is incorporated into the soil or applied as a drench around the base of the plants. This allows the active ingredient to move into the plant tissues through root uptake, providing systemic protection against pests.

3. Seed treatment: Thiamethoxam is commonly used as a seed treatment pesticide, where it is applied directly to the seeds before planting. This method ensures that the young plants are protected from early-season pests, as the insecticide is taken up by the emerging seedlings as they grow. Seed treatments are frequently used in crops such as corn, soybeans, cotton, and cereals.

4. Trunk injection: In certain cases, thiamethoxam can be injected directly into the trunk or stems of trees to control pests such as borers or leaf-feeding insects. This method allows the insecticide to be distributed throughout the entire tree, providing systemic protection.
