I need to know how much Biophos to add to 30 gal of water for a root drench?
For soil drench for homeowners, apply BIOPHOS PRO Fungicide at a 0.5% dilution. Mix 1/8 cup (2 tbsp or 1 oz) of BIOPHOS PRO Fungicide per gallon of water, and apply with a watering can or other device so as to wet the root zone. So for 30 gallons you would use a total of 30 oz of the BIOPHOS PRO Fungicde.
