¶ A. Emergence to Tillering (Feekes 1 to 4)
Plant Part: Whole plant
Sampling Procedure: Collect 30 to 40 tillers, cutting off about ½ inch above ground level. At least a pint of loosely packed tissue (a ball about 4 to 5 inches in diameter) should be submitted for analysis. Place sample in a paper bag, not a plastic bag, for shipment to the laboratory.
