The Comparison of Control Efficacy for 8 Insecticides Against Empoasca pirisuga Matumura
In order to screen the high-efficiency and low-toxicity agents that can be used to prevent Empoasca pirisuga Matumura,8 insecticides were selected to conduct the field efficacy test.The results showed 20％dinotefuran SG had the best control efficacy,the results were 72.34％,90.34％and 94.99％1,3 and 7 days after treatment respectively.25％diafenthiuron SC and 20％flonicamid SC had the second best control efficacy,the results were 89.88％and 86.06％7 days after treatment respectively.The rapid efficacy and persistence of 150 g/L indoxacarb EC,0.5％emamectin benzoate ME and 15％tolfenpyrad SC were not prominent.Although the 10％bifenthrin EW and 240 g/L chlorfenapyr SC had good rapid efficacy,their persistence were poor.Within the testing dosage,these eight insecticides were safe for tea trees.
