COTMAN is a crop information system based on in‑season plant monitoring. The COTMAN computer software makes it easy to enter and generate the reports used to make management decisions. It is divided into two parts, squareman and bollman.


SQUAREMAN is used to monitor crop development up to time of first flowers. Reports provide feedback on square retention and plant stress.


BOLLMAN is used when the crop is flowering to monitor boll-loading stress and to assist with end-of-season crop termination decisions. BOLLMAN utilizes NAWF data. A non-computer version of BOLLMAN is available.
