A new palmtop computer program was introduced in 1993 to help cotton growers use plant monitoring to better manage their crops. The program suggests what plant characteristics to monitor at different times of the year and provides interpretation of the plant monitoring information to help in Pix applications, lygus treatments, irrigation decisions, and defoliation timing. The program runs on an inexpensive ($400) Hewlett Packard HP 95LX palmtop computer or an IBM desktop computer, as a Lotus 123 menu driven macro.
