Which statement about application methods is true?

• A. Some pesticides cannot be applied by air
• B. All pesticides can be applied by air
• C. Pesticides must be applied by air
• D. Pesticides can be applied only by ground equipment

Answer: (A)

Applying a pesticide is governed by the product’s label, which specifies which methods are allowed. Not every product is approved for aerial use; some pesticides have drift risks, safety concerns, or specific formulation limits that restrict them to ground application. If the label says aerial application is not permitted or that ground application is required, you must follow that instruction even if you could physically apply it from the air. This is why the statement that some pesticides cannot be applied by air is true—the permitted method depends on the label and regulatory guidance.

It wouldn’t be correct to say all pesticides can be applied by air, or that pesticides must be applied by air, or that they can be applied only by ground equipment, because the label for many products may allow aerial use or require ground application, depending on the product. Always consult the label and abide by any local regulatory requirements to determine the proper method for each product.
