At right is a helpful table to calculate how much Paczol® should be added to a gallon of water to achieve a desired PPM when applying with a chemical injector. A common injection ratio is 1:100, meaning one gallon of concentrate (stock solution) is evenly dispersed via injection into 100 gallons of irrigation water.
For a 1 PPM rate with an injector set at 1:100, you mix 95 mL Paczol (3.2 fl oz) into one gallon of water (stock solution) and run the injector until the gallon is gone. Be sure to check that the 100 gallons used is appropriate for the square footage of bench space sprayed or for the number and size of pots being drenched.
| Injector Ratio All quantities are expressed in milliliters per gallon stock solution. |

Remember, sprays of PGRs, including Paczol, are typically applied at 2 qt. per 100 sq. ft. of bench space or 100 gal. per 20,000 sq. ft. Drenches are done at 2 fl. oz. per 4-inch pot, 4 fl. oz. per 6 inch pot, etc. Please check the Paczol label for specific instructions.
It is advised to leave a small portion of the crop untreated so an accurate evaluation of the growth suppression may be observed.
