Professional Use Guidelines


Open container that is partially filled with soluble concentrated powder. Top off container with water leaving enough head space to agitate (warm water is better). Replace cap and shake vigorously. Add to agitating spray tank. Apply with any type equipment that delivers an even spray pattern to the target area. Lightly water in immediately after application.


Extreme soil deficiencies should be corrected over a period of time with several applications. Frequent soil testing is recommended to ascertain soil magnesium levels and to maintain magnesium at desired levels. Defense-Mag is not recommended if either the irrigation water or the soil has high levels of magnesium. For actively growing turf, apply 14.4 lb / acre (12.8 kg / ha) every 4-6 weeks as needed. Do not apply to turf under heavy stress.


Defense-Mag is tank mix compatible with many systemic fungicides, insecticides, and nutrient solutions. Jar test when in doubt. Defense-Mag will tend to dramatically lower the pH of the spray solution. For best mixing results, remove tank strainer prior to product addition.
