COTMAN procedures were used to identify Type I and Type II growth patterns in fields located in three regions of the state in 1995. Comparisons are made as to the total number insecticide applications and their associated costs in Type I and Type II fields. Potential savings ($/A) with implementation of the COTMAN Insecticide Termination Rule were also examined. Results indicate greater control costs associated with Type II fields. When insecticide treatments are terminated according to COTMAN recommendations, a great potential for savings was realized.
