Bio MP can be applied through fertigation, conventional spray, or root injection. It may be applied alone or tank mixed with other products✝. Shake well before using.
Conventional Spray:
Apply 6 to 15 oz. diluted in 2 to 2.5 gallons of water per 1,000 sq. ft. (2 to 5 gallons diluted in 80 to 100 gallons of water per acre) per month. To maximize performance, rates may be split into weekly or bi-weekly applications.
Soil Drench:
Mix 1 – 2 fl. oz. of Bio MP per gallon of water. Drench to thoroughly saturate the root zone. Repeat application monthly or as needed.
Root Injection:
Dilution Rate: Mix 32 fl. oz. of Bio MP per 100-gallon tank. Apply as needed.
Operating pressure: 150 – 200 lbs PSI or ½ gal per 4 seconds
Area Method: Trees: Apply 50 gallons of solution per 1,000 sq. ft. Inject 4-8 inches into the soil where the feeder roots typically occur. Begin injections 1-3 feet out from the trunk to avoid injury to large roots and work in a grid pattern away from the tree to within 2 feet of the drip line. Apply 1 pint (16 fl. oz.) of diluted solution per injection site at 18 inch spacing or ½ gallon (64 fl. oz.) of diluted solution per injection site at 3 foot spacing.
Shrubs: Apply 50 gallons of solution per 1,000 sq. ft. Inject one pint (16 fl. oz.) of diluted solution per injection site. Inject 4-6 inches into the soil with 18 inch spacing between injections.
DBH Method: Use the chart below to determine the volume of diluted solution to apply per inch of trunk diameter at breast height (DBH).
