If the field is in an active eradication zone and will receive sprays for diapause control of boll weevil, late season plant bugs will also be controlled. This alone will create the possibility of setting a good top crop. After the top crop is set, weather becomes a limiting factor. Plant populations in the low 20,000 range, or as low as one per row foot with no, or very few skips, may maintain good yield potential. If a large percentage of those plants are severely damaged or if the stand is broken with numerous skips, replanting would be in order at populations below 30,000 plants per acre, depending on the size and frequency of skips.
Calendar date comes into play significantly.
A stand that you would plow up on May 1 would probably be kept on May 27. When making stand counts in a hailed damaged field, determine what percent of the field is damaged. Next examine plants to see what percent have a terminal, what percent do not have a terminal and what percent are cut off below the cotyledon node. Those cut off below the cotyledon node will probably not recover. Those that do not have a terminal will probably recover, but produce a crazy plant with many branches.
