Use & Instructions

Ready To Use Applications: For best results, spray before the disease is visible or at first sign of disease symptoms. Spray directly onto all plant parts thoroughly. Make sure to spray both tops and bottoms of leaves. Repeat applications every 7-10 days. Reapply after rainfall.

  4. To BEGIN spraying, point nozzle toward treatment site and:
    • Bend the safety tab back (located on the right of the dial) with your thumb.
    • Using your other hand, QUICKLY turn the dial clockwise until it stops. Water will automatically mix with the product.

  6. To STOP spraying, QUCKLY turn the dial in the opposite direction of "ON" until it stops and the safety tab engages the notch in the valve. Turn water off at faucet. To relieve pressure before removing nozzle from hose, bend the safety tab back and turn dial "ON" until water stops spraying.
