After thorough mixing, let stand for 5 minutes. If the herbicidelfertilizer combination remains mixed. or can be relT',)..ed readily, the mixture is compatible and can be sprayed.

Precautions for All Applications to Sorghum: (1) Heavy rain immediately follOWing application tends to cause excessive concentrations of herbicide in seed furrow, resulting in possible crop injury. Do not apply to furrow-planted sorghum until furrows are leveled ~plowed in). Level deep planter marks or seed furrows before application. (2) Application to sorghum growing under stress caused by minor element deficiency or to sorghum growing on highly calcareous SOil may result in crop injury. ~3) FollOWing harvest, plow (moldboard or disk-plowl and thoroughly till soil In fall or spring to minimize possible Injury to spflng-seeded rotational crops, regardless of rate used.
