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/hm2)防效最佳,药后7d防效在92%以上;43.7%甲维·丁醚脲悬浮剂(600 mL/hm2)、5%桉油精可溶液剂(1 350 mL/hm2)、20%呋虫胺可溶粒剂(450 g/hm2)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.
Abstract
In order to screen the chemical agents that prevent Empoasca pirisuga Matumura,and achieve the purpose of the insecticidal degra-dation,by spraying method in 2023,10 commonly used pharmaceuticals in Shucha Town,Shucheng County were selected to carry out field effi-cacy 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/hm2)was optimum,and 7 d after the drug was 92%.43.7%em-amectin benzoate·diafenthiuron SC(600 mL/hm2),5%eucalyptol SLX(1 350 mL/hm2),20%dinotefuran SG(450 g/hm2)wasmore than 83%.The above four insecticides showed better preventive effect on Empoasca pirisuga Matumura,and were relatively safe to tea tree and natu-ral enemy insects.It is recommended to use alternately in production.
