Rate 1 quart/A
Time Apply within 4 hr of mixing, or activity will be reduced.
Remarks For uniform plantings, spray once when two true leaves have developed. Spray nonuniform plantings twice: when first true leaf is the size of a quarter and again when third true leaf is expanding. Plant male or pollen rows ahead of seed parent; treatment often causes flowering 7 to 10 days earlier. Growth may be inhibited temporarily because of shortened internodes.
