GENERAL APPLICATION INSTRUCTIONS
This product is for use with the ARBORJET TREE INJECTION SYSTEMS or those systems that meet the label and dosage requirements. Follow manufacturer's directions for use. Micro-injection Applications for use as formulated PHOSPHO-jet may be applied undiluted by micro-injection. The PHOSPHO-jet dose rate is 5 mL per inch DBH.

Calculating Application Rate
The dosages and number of application sites are based on tree diameter.
To determine the application/dose rate per tree:
1) 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.)
2) Calculate the number of injection sites by dividing the DBH in inches by 2.
3) Multiply the tree DBH by the dosage rate (5 mL per inch DBH) to calculate the total dose in milliliters per tree.
4) Divide the total dose by the number of injection sites to determine required dosage per injection site. Example: For a tree with a DBH of 12 inches (or circumference of 36 inches) and 5 mL dosage rate:
1) DBH = 12" (circumference 36" -r 3 =12")
2) Divide DBH of 12" by 2 = 6 injection sites.
3) Multiply DBH" of 12 by 5 mL = 60 mL total dose per tree.
4) Divide 60 mL by 6 injection sites = 10 mL per injection site to deliver the required dosage.

Ornamental, Forest, Conifers, and Crop Trees
CALCULATING APPLICATION RATE AND MIXING INSTRUCTIONS (for micro-injection; for other methods see supplemental information)
1) To determine the application rate, refer to Table 1. Identify plant size by determining tree diameter in inches at breast height (DBH") (measured at approximately 54" above the soil line). (If measuring tree circumference divide by 3 to obtain the DBH".)
2) Multiply the DBH" by the corresponding amount in the rate column to determine the application rate appropriate for plant size.
3) 1 part PHOSPHO-jet is diluted with 2 parts water. Determine the amount of water to be added by multiplying the ml PHOSPHO-jet (obtained in step #2 above) by 2.
4) Fill the tank with the water before adding PHOSPHO-jet.
5) Add PHOSPHO-jet slowly to the tank, close and gently agitate to mix.
Example: To treat a 10" DBH oak for root rot, see Table 1. Add 50 ml of PHOSPHO-jet (10" DBH x 5ml) into 100 ml (2 x 50 ml) water for a total injection volume of 150 ml. Inject 30 ml of the PHOSPHO-jet/water solution every 6" of trunk circumference as directed in Supplemental Label Arborjet Injection Procedures.
