| Abstract: | The current situation of pesticides used in five counties in mulched maize areas in the south of the Loess Plateau from 2017 to 2019 were investigated and analyzed. The results showed that the sales of insecticides, fungicides and herbicides accounted for 35.8%, 26.1%, and 38.2% of all pesticides sales by 15 major pesticides sellers and 100 farmland holders in 2019, respectively. There were mainly 13 types of insecticides, 10 types of fungicides and 11 types of herbicides. In terms of pesticide used in the Farmers'' maize fields from 2017 to 2019, insecticides were the most frequently employed, 1.6 sprays per season, with an average dose of 591 mL/ha per spray. Herbicides were usually sprayed once per season with the highest dose of 2 257 mL/ha. Fungicides were almost never used, only 0.3 sprays per season with the dose of 909 m/ha. |
