摘要
为筛选出用于防治茶树茶小绿叶蝉的高效低毒药剂,选择8种杀虫剂开展了田间药效试验并进行了比较.结果表明:20％呋虫胺可溶粒剂对茶树茶小绿叶蝉的防治效果最好,药后1、3、7 d防效分别为72.34％、90.34％和94.99％;其次为25％丁醚脲悬浮剂和20％氟啶虫酰胺悬浮剂,药后7 d防效分别为89.88％和86.06％;150 g/L茚虫威乳油、0.5％甲维盐微乳剂和15％唑虫酰胺悬浮剂对茶树茶小绿叶蝉速效性和持效性均不突出;10％联苯菊酯水乳剂和240 g/L虫螨腈悬浮剂虽速效性较好,但持效性较差.8种杀虫剂在试验剂量下对茶树安全.
Abstract
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.
