Professional Use Guidelines


Apply with any equipment that delivers a fine, even spray mist to the target area utilizing 02-04 tips for a total spray volume of 20-40 gpa (200-350 L/ha). Do not water in. Wait at least 2 hours to irrigate.


Knife Plus can be applied as a corrective measure for iron deficiencies or, more ideally, as a maintenance spray program to preclude the development of deficiency signs and symptoms. Apply to turf at the rate of 1-3 fl oz / 1000 sq ft (5-10 L/ha).


Knife Plus is tank mix compatible with many systemic fungicides, insecticides and nutrient solutions. Jar test when in doubt. For best mixing results, remove tank strainer prior to product addition. Shake well before using.
