TESTING FOR PRODUCT COMPATIBILITY IS IMPORTANT! Since formulations sometimes change and are not all created equally, users should perform a jar test to determine the physical compatibility of the products being introduced into the spray tank and to determine water volume proportional to the water volume of the planned spray tank. NOTE: If the tank mix is not compatible, a higher water volume, reduced rate of tank mix partners, reduced number of tank mix partners or a compatibility agent (such as KALO’s Compex or Compex Extra) may be needed.
JAR TEST INSTRUCTIONS
Pour 1 pint (16 ounces) of water into a 1 quart (32 ounce) jar.
Add the correct proportion of fertilizer and wettable powders to the water and ensure that the materials are uniformly mixed. Add aqueous components individually, again ensuring each is mixed uniformly.
Add emulsifiable concentrates (EC) compounds last. Invert (DO NOT SHAKE) the jar 10 times to mix and let stand for at least one hour.
Inspect for unusual signs such as participates, clumping or layering in the mixture.
It is important to remember that a jar test will only show physical incompatibilities and not phytotoxic incompatibilities.To check for the latter, test by spraying an inconspicuous spot.
