【摘要】 为筛选出安全高效防治茶小绿叶蝉的化学药剂，达到控虫减药的目的，利用喷雾法于2023年在舒城县舒茶镇选择10种常用药剂开展对茶小绿叶蝉田间药效试验。结果表明，各供试药剂对茶小绿叶蝉均有一定防治效果，其中25%呋虫胺·唑虫酰胺悬浮剂(450 mL/hm~2)防效最佳，药后7 d防效在92%以上；43.7%甲维·丁醚脲悬浮剂(600 mL/hm~2)、5%桉油精可溶液剂(1 350 mL/hm~2)、20%呋虫胺可溶粒剂(450 g/hm~2)防效次之，7 d防效在83%以上。上述4种药剂对茶小绿叶蝉均表现出较好防效，对茶树和天敌昆虫相对安全，可在生产上推广使用。更多还原

【Abstract】 In order to screen the chemical agents that prevent Empoasca pirisuga Matumura, and achieve the purpose of the insecticidal degradation, by spraying method in 2023, 10 commonly used pharmaceuticals in Shucha Town, Shucheng County were selected to carry out field efficacy tests on Empoasca pirisuga Matumura.The results showed that all the tested insecticides had a certain prevention effect on the Empoasca pirisuga Matumura, of which 25% dinotefuran·tolfenpyrad SC(450 mL/hm~2) was optimum, and 7 d after the drug was 92%.43.7% emamectin benzoate·diafenthiuron SC(600 mL/hm~2),5% eucalyptol SLX(1 350 mL/hm~2),20% dinotefuran SG(450 g/hm~2) was more than 83%.The above four insecticides showed better preventive effect on Empoasca pirisuga Matumura, and were relatively safe to tea tree and natural enemy insects.It is recommended to use alternately in production.更多还原
