Symptoms of sorghum can develop throughout the reproductive period. Infection can cause seedling blight or root rot. The roots became watery at the beginning of the disease and became black afterwards. The internal tissues collapsed and the cortex rotted and extended to the lateral roots. The culm infected plants matured earlier, the spikes were small, and the wind easily collapsed. After disintegration of the internal tissues of the stems, vascular bundles remain, including a large number of black sclerotia. China's sorghum production areas have occurred.
The pathogen, Macrophomina phaseoli (Maubl.) Ashby, is known as the bean fungus of the genus Aspergillus subsp. Conidiophore dark brown, spherical, early buried, scattered, diameter 89-275um; sporogenous cells gourd-shaped, colorless, size 5-134-6 (um); conidia unit cells colorless, cylindrical or Spindle shape, size 16-325-10 (um). Sclerotia black, hard, diameter 5-100um.
Transmission routes and pathogenic conditions The pathogenic bacteria in the soil with mycelium or sclerotia overwinter in the soil. The conditions of late spring are suitable for producing conidia, which are transmitted by rainwater spattering, and the spores germinate for initial infection, causing the onset of seedlings or adult plants. The conidia produced by the disease department were repeatedly infested by wind and rain. The high temperature and humidity in the field, low-lying terrain and soil moisture contribute to the disease.
Prevention methods (1) Dispose of the diseased body promptly after harvest, and concentrate deeply or burn it to reduce the bacteria source. (21 conditions can be used with rice and wheat rotations.) (3) Application of enzyme compost composting, pay attention to increase potassium fertilizer to enhance the host disease resistance. (4) Trichoderma viride inhibition of this bacteria can be It is mixed with cake fertilizer to make antibiotic protoplast fertilizer.(5) Spray 50% ceric acid copper (DT fungicide) wettable powder 500 times or 80% new Wansheng wet powder 600 times if necessary. L0 days, continuous control 2-3 times.

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.
