Results from the logistic analysis show that IPM training and improving farmers' knowledge will significantly reduce pesticide misuse by the farmers, while the errors in farmer's expectation on yield loss due to pest attack will significantly increase the probability of pesticide misuse by the farmers. Pesticide misuse is also expected to decline with the increase of time spent for filed visit and pest monitoring. Since there were large errors in the farmers' expectation on yield losses due to pest, improving farmers' estimation on yield losses due to pests will significantly decrease pesticide misuse by the farmers.
