Based on panel data from 25 provinces(regions,cities)in China from 2005 to 2018,this study investigated the effects of accumula-ted temperature and precipitation during crop growth on pesticide inputs.The baseline regression results showed that climate factors had a signif-icant impact on pesticide input.Both accumulated temperature and precipitation during the crop growth period had a significantly positive effect on pesticide input,and their synergistic effect was also significant.Heterogeneity analysis showed that pesticide use in northern and high-yield regions was more sensitive to climate factors,with a greater impact.Farmers'education level increased,labor per acre decreased,and regional disaster rates increased,the promoting effect of climate change on pesticide use became more pronounced.Therefore,when formulating pesticide reduction policies,we should pay attention to the impact of climate change,establish an early warning mechanism for agricultural climate,im-prove the agricultural insurance system,and reduce the potential motivation of farmers to over-apply pesticides through effective risk manage-ment.
