Abstract: Excessive use of chemical fertilizers and pesticides in potato （Solanum tuberosum L.） production not only leads to resource waste and cost increase, but also causes a series of problems, such as declining soil fertility, increasing pesticides resistance, declining quality of potato tubers and low utilization rate of fertilizers and pesticides. The application of chemical fertilizers and pesticides in the main potato producing areas in the northern plain of Hubei province was systematically investigated, and the main problems due to overuse of chemical fertilizers and pesticides were analyzed, such as the lack of efficient substitute products and technology, the backwardness of precision application equipment, and the unscientific application of fertilizers and pesticides. Finally, combined with the actual potato production in the northern plain of Hubei province, some countermeasures were put forward, such as strengthening government guidance, formulating relevant industrial support policies, accelerating the research and demonstration of key technologies for reducing fertilizer and pesticide application, increasing propaganda guidance and technical training, and strengthening brand building.
