Tools Needed

To apply PHOSPHO-jet Systemic Fungicide, you will need a handheld pump sprayer, hydraulic sprayers, backpack sprayer, hose-end sprayer, chemigation system, micro irrigation (spaghetti systems), or ebb and flow systems.

How to Use

• Step 1: Determine how much PHOSPHO-jet Systemic Fungicide to use by measuring the square footage of the treatment area. To do this, measure the length and width of the treatment area in feet then multiply them together (length X width = square footage). Measure the tree diameter in inches at chest height (54" from ground) to find the Diameter at Breast Height (DBH). (If measuring tree circumference, divide circumference by 3 to obtain the DBH in inches.) Calculate the number of injection sites by dividing the DBH in inches by 2. Multiply the tree DBH by the dosage rate (5.0 mL per inch DBH) to calculate the total dose in milliliters per tree. Divide the total dose by the number of injection sites to determine required dosage per injection site. For citrus trees, apply 2 1/2 quarts of PHOSPHO-jet Systemic Fungicide in 250 gallons of water per acre as a foliar spray. For palm trees, use 4 tsp. and 2 fl. oz of product per tree. For turfgrass, apply 5 to 10 fl. oz. of product in 2 gallons of water per 1,000 sq. ft.
• Step 2: Fill your sprayer with half the amount of water, add measured amount of PHOSPHO-jet Systemic Fungicide, then fill with the remaining half of water. Close the spray tank lid and shake until the solution is well-mixed.
• Step 3: Spray the PHOSPHO-jet Systemic Fungicide mixture until the entire tree trunk and plant leaves are saturated to the point of runoff. Apply every 14 to 21 days in a fungicide rotational program. When applying to indoor plants, do not overspray and use care to apply only to target plants.
