This product may be applied as a water, oil, or adjuvant based spray. Use 
coarse sprays to minimize drift. DO IIOT apply where spl'ay may cOlbe in contact 
with any desirable plants or susceptible cropa other than those l~sted on this

When using ground squipment, keep boom or nozzles close to crop, apply 2U 
gallons o~ more of spray per acre using flooding or flat fan nozzles with 20 
pounds or less of pressure. If wind exceeds 7 miles per hour, spraying should 
stop. DO HOT· apply. with hollow cone or any other mist producing nozzle. 
When using aerial equipment, apply a minimum of 3 to 5 gallons of spray per acre 
at 20 pounds or less nozzle pressure using nozzles that produce a coarse spray 
pattern. Spray only when w~nd is blowing less than 5 miles per hour.

quart jar test as follows: The amount of this product to add to one pint of 
liquid nitrogen fertilizer is determined by using this table --

The amount in the table is based on galions of finished spray per acre. 
Different spray volllllles will require appropriate changes in the amount of this 
produot added to one pint of fertilizer. Add the required alliount of this 
produot to one pint of fertilizer in a quart jar and shake to lIIix well. Let the 
mixture stand and examine it after 5 lIIinutes and again after 30 lIIinutes. The 
produot is incompatible if it balls up, fol'lls flakes, sludges, gels, oily films, 
layers, or other precipitates. If the precipitate oan be suspended with 
agitation the combination can be used if the equiPlilent has vigorous agitation 
throughout mixing and spraying operations. . 
In some cases, wb .. n incompatibility occurs, the addition of 11" teaspoon o:r a 
compatibility agent to the jar before adding this produot may solve the problelll 
(11" teaspoon is equal to 2 pints per 100 gallons of fertilizer). IF THIS DOES
