The breeding of resistant rice varieties takes many years of trials and is not easy. In the transition stage, proper cultivation systems, such as rational fertilization, can help to increase crop disease resistance and insect tolerance. In the previous study, it was found that lacking trace elements in plants displayed higher susceptibility to diseases; while increasing the concentration of trace elements can enhance plant insect resistance. However, there is little know about the correlation between the trace elements and rice insect resistance, which makes it difficult to apply for. This project first determines the concentration of different trace elements, which is supposed to not affecting the growth of rice plants. Next, the insect resistance to the rice leaf folder ( Cnaphalocrocis medinalis ) were compared and evaluatedwhether different trace elements can contribute to the resistance of the common Taiwan insect pests in rice. The application of micronutrients to increase the crop insect resistance can reduce the use of pesticides, leading us closer to the goal of environmental sustainability.水稻微量元素瘤野螟ricetrace elementsCnaphalocrocis medinalis
