More product information
Choosing a product: This combines deltamethrin adulticide with PBO synergist; it does not contain an insect growth regulator. For deltamethrin without built-in PBO, compare Centynal EC. For deltamethrin plus an IGR, compare Diacon IGR Plus. See application equipment and the grain protectant calculator. Always follow each product label.
