The symptoms are also known as black mold, aspergillosis. More occurs in the seedling stage. Stems at the base of the stem appeared dark concave chloasma, and the edges were brown. After the lesions were enlarged, the epidermis was longitudinally cracked, and it was dry and rot. Only the broken fibrous tissue remained and the pith of the vascular bundle became purple-brown. The disease minister is full of black moldy matter, namely the conidiophores and conidia of pathogens. The diseased plant showed water loss in the upper part of the plant and soon withered to death. The nuts are rotted and cannot germinate and grow black mold. The cotyledon and hypocotyl junctions were infested, and the cotyledons blackened and rotted. The pathogen is Aspergillus niger van Tiegh. It is called Aspergillus niger and belongs to the fungus Aspergillus spp. The tip of the conidiophore stem is inflated with a nearly spherical shape, with an upper radial stem and a series of round, single cell, brown conidia. Conidia size 2.5-5 μm. In addition, A. pulverulentus (Mcalpine) Thom can also cause disease.
Transmission Pathways and Pathogenic Conditions Germs use hyphae or conidia to overwinter in soil, sickness or seeds. After sowing peanuts, the wintering germs produced conidial invading cotyledons and germs, severe deaths could not be excavated, and lighter people had conidia on root and neck lesions after unearthing, and reinfested by wind and rain and airflow. Peanut trees are the most severe onset. Alternating between high temperature and high humidity or drought or wetness facilitates the onset of disease. Poor drainage, management of heavy land mass. Continuous cropping of peanut fields is easy.
Control methods (1) Select seed selection full of disease-free, mildew-free seeds. (2) Implement 2-3 year rotation. (3) Strengthen field management. Sowing should not be too deep. Do not apply organic fertilizer. Remove water after the rain. (4) Seed treatment with seed weight of 0.2%-0.5% 50% carbendazim wettable powder seed dressing or liquid soaking, can also be used seed weight 0.5% -0.8% of 25% phenanthrenequinone powder or 0.2% of 50% Fumei double powder dressing.

The main features:
1)Ideal cold light effects
Using the new LED cold light source, ensure energy saving and environmental protection and long service life up to 80,000hours and more.
The temperature increase of surgeon`s head below 1℃. LED do not engender infrared ray and ultraviolet radiation, without the temperature
rise and tissue damage caused by halogen shadowless light, also it can accelerate the wound healing after surgery, and without Radiation pollution.
With color temperature constant and soft, LED is very close to the sunshine.
1) Excellent shadowless effect
Lamp with the most scientific radian and Multi point light source design, ensure better uniform illuminance. When the lamps are partially occluded,
also can achieve perfect shadowless effect.Lamp panel radius of gyration ≥182cm, the lamp can be pulled to vertical floor, convenient to any angle illumination.
2) Excellent deep lighting
It is based on modularize method by Computer Aided Design, focused to irradiating with more beams of LED. It produces the deep lighting which beams
more than 1200cm,the illumination of center up to 180,000Lux or more, and offer the color temperature that can be adjusted from 3700K to 5000K which
is close to sunshine. Absolutely, it really reflects the color of human tissue and satisfied by all kinds of operating light needs.
3) Advanced control system
The use of liquid crystal display button control, to meet the needs of the medical staff of different patients with the brightness of the operation.
It offers illuminance memory function.
It does not effect using when a single circuit or one bulb is broken.
4) Universal suspension system
Rotating arm, a new type of alloy material is made of eight edge type.
Balanced system using imported arm module, more than 5 group universal joints, every cantilever must has more than 3 joints which can be rotated in 360°,
The structure is light, easy to manipulate, accurate positioning, can provide the maximum range of regulation.The equipped with fatigue correcting unit and
fix position hand handle device, easy to fix position after long time use.
5) Modern laminar lamp
The thickest part of lamp-chimney is not more than 10cm.
The lamp-chimney is made of ABS, The handle on the central of lamp can be detachable, can take high temperature (≤ 134°C) sterilization treatment,
easily adjust, flexible fixed.
