Our cotton is looking pretty good right now and the oldest fields have started squaring.
There isn’t too much going on in the fields to be concerned about right now. Insect pressure has been low (just a few aphids here and there) and there are plenty of natural enemies present. Rain has been coming pretty regularly also.
Squaring is when we want to sidedress our remaining nitrogen as the plants will be needing it once bloom starts. Clemson Cotton Specialist Mike Jones recommends 70 total lbs of N per acre in dryland fields and 100 total lbs in irrigated fields. He recommends putting out 25-33% at planting and squaring is the time for the rest.
