The mixing rate for Agrisel BioPhos Pro Systemic Fungicide varies depending on where you are treating (residential, commercial, agricultural, crops, etc) and what disease you are treating for. Please refer to page 3-5 of the product label for specific mixing rates. The residential/homeowner application instructions are below. For preventative control of certain diseases in ornamentals. For soil drench, apply BIOPHOS™ PRO Fungicide at a 0.5% dilution. Mix 1/8 cup (2 tbsp) of BIOPHOS™ PRO Fungicide per gallon of water, and apply with a watering can or other device so as to wet the root zone. For foliar application, apply BIOPHOS™ PRO Fungicide at a 1% dilution. Mix 1/4 cup (4 tbsp) per gallon of water and apply with a hand or backpack sprayer. Apply to run-off.
