Gun-type sprinklers should not be used. They spray a fine mist high into the air which is more likely to be carried by the wind. Locate the irrigation equipment to cover the entire field but do not place the sprinklers close to the field edge. This reduces the likelihood of pesticide runoff or drift into non-target areas. Apply only those pesticides labeled for use in irrigation systems.
Labels also have information on procedures and restrictions.
Consult your county extension agent if you are in doubt. Make sure your equipment is in good operating order at all times. If chemigation is to be safe and efficient, the equipment must be in good working order. A complete listing of specifications, inspection requirements, and methods of operation of a chemigation system may be obtained from your county extension agent or from the North Carolina Department of Agriculture.
