Data collection is required once or twice per week.
The Target Development Curve begins with first square at 35 days after planting. At 60 days after planting, or approximately first flower, the curve reaches an apogee of 10.25 squaring nodes, or 9.25 nodes above first square. The target development curve then begins its descent and should reach 5 nodes above white flower at 80 days after planting. The first fruiting node is also recorded. Insecticide termination for bollworms and boll weevils is advised at 350 heat units after cutout, and defoliation is advised at 850 heat units after cutout.
