Phyllotreta striolata is one of the main pests of cruciferous vegetables at present. Due to its biological characteristics, the commonly used method of foliar spray is inefficiency and causes problems of excessive pesticide residue. In order to explore the control methods and effective agents for controlling P. striolata, the effects of 2% thiamethoxam and cypermethrin granules on the field control efficiency and yield of P. striolata were evaluated by soil treatment with mustard as the experimental vegetable. 2% thiamethoxam-cypermethrin granules had a strong control effect on P. striolata. At the dosage of 2 kg/667 m 2, the control effect was 76.67%, 72.00% and 70.64% at 14, 21 and 28 d, respectively. At the same time, the agent also had a certain effect on promoting the growth of mustard. The total yield at the dose of 2 kg/667 m 2 was 58.80% higher than that of the untreated fields. The residue analysis of mustard postharvest showed that the residue of thiamethoxam and cypermethrin in mustard and soil was less than 0.5 mg/kg, which met the corresponding terms of National standard for food safety-maximum residue limits for pesticides in foods (GB 2763-2016). Therefore, it is safe and effective to apply 2% thiamethoxam - cypermethrin granules to control P. striolata on mustard. In addition, the soil application method used in this study was a one-time application, which greatly reduced the dosage and labor cost compared with foliar spraying.
