This experiment was carried out to determine the treatment interval on neem product for control of Bemisia tabaci on eggplant using eco-friendly agriculture. We have investigated the control effect of B. tabaci, growth characteristics of eggplant, economics according to neem product treatment interval on eggplant. The longer neem processing interval tended to decrease control effect on nymphs of B. tabaci. Control effect of nymph of B. tabaci according to treatment interval of 3 days, 5 days, 7 days, 10 days, and 15 days were 96.7%, 89.7%, 76.1%, 73.4%, and 51.0%, respectively. This result was the same tendency in adult of B. tabaci control effects on eggplant. Growth characteristics of eggplant according to neem the treatment interval of 3 days, 5 days, and 7 days, was less damaged on of B. tabaci. However, the 10 days, 15 days, and untreated of neem treatment intervals were badly damaged by B. tabaci. Therefore, neem treatment interval of 3~7 days for control of B. tabaci was high control effect. However, it is considered to be the most suitable to process every seven days considering the economics and so on. The results of economic analysis from income of 7 days neem treatment interval was the most high as 19.505 thousand won per 10a and the most economical treatment for control of B. tabaci.
