内容是:
症状:
1.蒂部初期暗褐色,无光泽,病健交界明显,不久病部转为深褐色至黑褐色,病果的果肉液化,果皮开裂,有汁液外流.
2.发病初期在果蒂上产生暗黄褐色病斑,病斑后转为深褐色,果肉液化、流汁,有酸味.
3.在发病初期蒂部呈暗黄色,水渍状,病部果皮皱缩,无汁液外流,后期病部转成浅褐色至黄褐色.
芒果蒂腐病 主要为害果实,贮运期发病.
病 原 :
芒果黑色蒂腐病的病原菌为球二孢菌(Botryodiplodia theobromae Pat,异名为Diplodia natalensis Evans),属于半知菌亚门.未成熟分生孢子无色、单胞、壁厚、椭圆形;成熟的分生孢子为榄褐色,双胞,表面具纵纹.
病 原 :
芒果褐色蒂腐病的病原为芒果拟茎点霉(Phomopsis mangiferae Ahmad),属半知菌亚门,A型分生孢子多数椭圆形,透明,单胞;在培养基上有时出现钩丝状的B型分生孢子.
发病规律:
蒂腐病菌的侵入途径是从花期侵入,在幼果内潜伏,在果实后熟阶段表现症状.此外,病菌可以从采果时的伤口及剪口侵入,而且这是病原菌更重要的侵入途径.
果园发生蒂腐病的传播途径主要是分生孢子通过雨水和气流传播.而在果实采后的运输期,则主要是靠病果与健果相互接触、由菌丝体传播.
 紫花芒、桂香芒、串芒、粤西一号、秋芒等品种较感病.
防治方法 :
 1.采前栽培防病综合措施 :
(1)种植丰产优质又较抗病品种.
(2)适当密植
(3)整形修剪
(4)清园卫生
(5)在采前采后及贮运过程中尽量减少果实的损伤.
(6)药剂防治
 2.采后处理措施 包括
(1)剪果
(2)洗果
(3)选果
(4)防腐处理
(5)分级包装
Symptoms:
1. Pedicle initially dark brown, dull, ill health at the junction of obvious disease soon became dark brown to black Department of brown rot of the pulp liquefaction, skin cracking, a juice outflow.
2. In the early stages to generate dark brown at the stem end spots were changed to dark brown, pulp liquefaction, flow juice, sour taste.
3. Pedicle in the early stages, was dark yellow, Shuizi Zhuang, Department of skin disease shrinkage, no juice drain, later turned into light brown disease to the Department of brown.
Major damage mango fruit rot, storage and transportation of disease.
Diseases of the original:
Mango black rot pathogen was ball two sp (Botryodiplodia theobromae Pat, different name Diplodia natalensis Evans), a semi-known fungus door. Immature conidia colorless, single cells, wall thickness, oval; mature conidia brown for the rugby, twin, surface with vertical lines.
Diseases of the original:
Brown rot of mango for the mango pathogen Phomopsis (Phomopsis mangiferae Ahmad), is a semi-known fungus door, A-type conidia most oval, transparent, single cell; sometimes appear in the medium hook filamentous B-type conidia.
Occurrence:
City rot pathogen pathways from flowering invasion, hidden inside the young fruit, the fruit ripening stage presenting symptoms. In addition, the bacteria can result from mining and rhizoma wounds when invaded, and it is more important pathogenic pathways.
Fruit rot occurred in the main mode of transmission is the spread of spores by rain and airflow. In the post-harvest transport period, mainly through disease and healthy fruit fruit contact with each other, spread by the mycelium.
Purple Mount, cinnamon fern, string Mountain, west of Guangdong on the 1st, autumn Mountain and other species more susceptible.
Control methods:
1. Adopt comprehensive measures to prevent diseases before planting:
(1) high yield of high quality planting more resistant varieties.
(2) proper dense
(3) pruning
(4) clear health park
(5) in the preharvest and postharvest fruit storage and transportation process to minimize the damage.
(6) Chemical control
2. Postharvest treatment measures, including
(1) cut fruit
(2) washing fruits
(3) election results
(4) treated with preservatives
(5), grading and packaging
