AbstractTo understand the characteristics of pesticide application and reduction potential in Zongyang County, Anhui Province,an analysis was conducted based on field surveys and statistical data,employing descriptive statistics, structural decomposition,and trend analysis.The study examined theplanting structure of major crops,theoccurrence and management status of diseases,pests,weeds,androdents,as wellas thecompositionof pesticideapplication and its toxicitycharacteristics.Theresultsshowed thatin2O24,thetotal planting areaof majorcrops intheresearcharea was 98 979.07hm2 , with rice and rapeseed being the primary crops. The annual occurrence area of diseases, pests, weeds, and rodents reached 184833.33hm2⋅ times,with a control area of 447 413.33 hm 2⋅ times, recovering 56 996.49 tons of crop losses.Pesticide application continued to decline,totaling 150.O6 t in 2O24,a reduction of 7.57% compared to 2020.The pesticide structure wascontinuouslyoptimized,withadecrease inthe proportionof insecticides,an ncrease in fungicides,and herbicides remaining stable at approximately 51% -67%.Slightly toxic and low-toxicity pesticides accounted for 90.52% of the total, indicating an overall trend toward reduced toxicity in pesticide application. Correlationanalysis revealed that changes in planting structure and the occurrence patterns of diseases and pests jointly influenced thepesticideapplication structure,while thepromotion of greenpreventionand control technologies and specialized unified control were key driversof pesticide reduction.Based on these findings,it is recommended to continue advancing eforts in“optimizing planting structures to reduce cross-risks ofdiseases and pests,strengthening disease and pest monitoringand early warning for precise control,and continuously improving the coverageof green prevention and control and specializedunified control.”These measures aimto further amplify the reduction ffectsof technology promotionandachieve coordinatedoptimization of planting structures,diseaseand pest management,and pesticide application.
