Air-assisted sprayers are particularly useful for penetrating dense foliage and ensuring thorough coverage. They are commonly used in orchards and vineyards.
• Electrostatic Sprayers: These sprayers give the pesticide droplets an electrical charge, which causes them to be attracted to the target surface. This results in better coverage and reduced drift, as the charged droplets are less likely to be carried away by the wind. Electrostatic sprayers are used in greenhouses, nurseries, and other enclosed environments.

Granular Application

Granular application involves using granular pesticides, which are solid particles coated with the active ingredient. These granules are applied to the soil or target area using spreaders or applicators. Granular pesticides are often used for controlling soil-borne pests, weeds, and insects.

• Broadcast Spreaders: These spreaders distribute the granules over a wide area, making them suitable for large fields and lawns. Broadcast spreaders can be either push-type or tractor-mounted, depending on the size of the area to be treated.
• Drop Spreaders: These spreaders drop the granules directly onto the soil, providing more precise application and reducing the risk of off-target drift. Drop spreaders are often used for applying granular herbicides along sidewalks and driveways.
• Rotary Spreaders: Rotary spreaders use a spinning disc to distribute the granules, providing a wider and more uniform coverage compared to drop spreaders. They are commonly used for applying fertilizers and pesticides to lawns and gardens.

Fumigation

Fumigation involves using gaseous pesticides to control pests in enclosed spaces, such as buildings, warehouses, and soil. Fumigants are highly toxic and require specialized equipment and training to apply safely. They are often used for controlling stored product pests, termites, and nematodes.

• Soil Fumigation: This involves injecting fumigants into the soil to control nematodes, fungi, and other soil-borne pests. Soil fumigation is often used in agriculture to prepare the soil for planting crops.
• Structural Fumigation: This involves sealing a building or structure and releasing fumigants inside to control pests such as termites, cockroaches, and rodents. Structural fumigation requires careful planning and execution to ensure the safety of people and the environment.
• Space Fumigation: This involves releasing fumigants into an enclosed space, such as a warehouse or container, to control stored product pests. Space fumigation is often used to protect grains, fruits, and other commodities from infestation.

Seed Treatment

Seed treatment involves applying pesticides to seeds before planting to protect them from pests and diseases during germination and early growth. Seed treatments can be applied as a coating, dust, or liquid, depending on the pesticide and target pest.

• Fungicide Seed Treatment: This involves applying fungicides to seeds to protect them from fungal diseases such as damping-off, seed rot, and seedling blight. Fungicide seed treatments are commonly used in crops such as corn, soybeans, and wheat.
• Insecticide Seed Treatment: This involves applying insecticides to seeds to protect them from insect pests such as wireworms, cutworms, and aphids. Insecticide seed treatments are often used in crops such as cotton, canola, and sunflowers.
• Combination Seed Treatment: This involves applying a combination of fungicides and insecticides to seeds to provide broad-spectrum protection against pests and diseases. Combination seed treatments are becoming increasingly popular as they offer comprehensive protection and reduce the need for foliar applications.

Other Methods

Besides the methods mentioned above, other pesticide application techniques exist, including:

• Baiting: This involves using pesticide-laced baits to attract and kill pests. Baiting is commonly used for controlling rodents, insects, and other pests.
