- 摘要:
- 以红枣缩果病病果样品为试材，通过常规组织分离、致病性测定、病原菌鉴定和田间药剂试验，研究巴州地区红枣缩果病病原菌种类以及常用杀菌剂对该病的田间防治效果。结果表明：从采集缩果病典型病样38份中，分离获得了156 个菌株，其中链格孢菌Alternaria 154个，占总菌株数的98.72%;镰刀菌Fusarium 2 个，占1.28%。确定巴州地区红枣缩果病是链格孢Alternaria alternata (Fries) Keissle所致的真菌性病害。80%大生M-45WP、75％百菌清WP和50%多菌灵WP在7月中旬以前进行田间防治效果较好，可作为防治枣缩果病的药剂。
- Abstract:
- Taking disease fruit samples caused shrink disease of jujube as test materials，through routine tisseue separation and determination of pathogenic，pathogen identification and field potions test,Bazhan area jujube-fruit shrink disease pathogen reduction type and the field control effect commonly used fungicides were studied.The results showed that a total of 38 samples fruit shrink disease of jujube were collected from 22 jujube orchards in Xinjiang Bazhou area and 156 isolates were isolated，among them，there were 154 Alternaria strains，accounting for 98.72% of the total.There were 2 Fusarium strains，accounting for 1.28%．The pathogenic of isolates were determinated and the morphology were identified．A．alternata (Fries) Keissle，were pathogen of Jujube-fruit shrink disease.Screening test for 3 kinds of 80% Mancozeb WP，75% chlorothalonil WP and 50% carbendazim WP before middle of july to the field control effect was good，it could be used as prevention and control of jujube-fruit disease fungicides.
