Survey on the current status of pesticide use for sanitary purposes in Shandong Province from 2019 to 2021
Objective To understand the current situation of the use of sanitary pesticides in Shandong Province,and to provide a theoretical basis for the scientific use of sanitary pesticides and the effective delay of the occurrence and development of drug resistance.Methods The use of sanitary pesticides in vector biological control-related units(CDC,Ai Wei Office,Pest Control Organization)in each city of Shandong Province was investigated using an on-site questionnaire survey;Summary and statistics on the types,formulations,quantities and methods of use of sanitary pesticides used,etc.,using Excel 2019;SPSS23.0 was used to carry out x2 test on the compounding of sanitary pesticides,the composition of active ingredients,and the amount of use,and to carry out a trend analysis of the use of sanitary pesticides over three years based on Spearman's correlation analysis.Results Chemical insecticides accounted for 68.69％of the pesticides used for sanitation in Shandong Province in 2019-2021,dominated by single agents and binary compounding agents;Among the formulations,wettable powder accounted for 23.76％,emulsifiable oil accounted for 18.80％,suspending agent accounted for 14.53％,bait and paste accounted for 12.69％,and water emulsion accounted for 8.88％,and the prevention and control targets were mainly mosquitoes,flies and cockroaches.Among rodenticides,bromadiolone accounted for 91.48％,bromacil accounted for 4.26％,while the formulations included 78.36％of baits and pastes,11.48％of granules,and 5.57％of water emulsions.Differences between pesticide compounding for sanitation in different units were statistically significant(x2=13.954,P＜0.05).Conclusion Among the pesticides for sanitary used in Shandong Province during the period 2019-2021,insecticides were dominated by pyrethroids,and the main formulations were wettable powders,emulsifiable oils,suspensions,and baits and pastes;the rodenticides were dominated by bromadiolone,followed by brodifacoum,and the main formulations were baits and pastes.Since the long-term use of large quantities of sanitary pesticides might cause resistance,the use of sanitary pesticides should be scientifically and rationally selected in future control in conjunction with the results of resistance monitoring.
