Symptoms Brown rot of Fusarium oxysporum is also called brown spoilage disease. Is an important disease in the production of yam. The early ground floor does not show obvious symptoms, and it can be seen at harvest time. Juvenile potato infections are now corrupted with irregular brown spots or deformity. The diseased part becomes soft after a slight rot. After the incision, the browning part of the tubers is often larger and deeper than the external lesions. Transmission routes and onset conditions wintering on soil or seeds with noxious or chlamydospores or conidia. Contaminated fertilisers, seeds, and diseased soils become the primary source of infection for the following year, and conidia are produced on the diseased section. Infestation spreads by rain splashing. Planting land and continuous cropping or low-lying, poor drainage, overly viscous soil, and underutilized soil miscellaneous fertilizer are all easy to induce the disease. Control methods (1) Collect residues of the disease as early as possible during harvest, and burn the soil deeply or use sun heat and film to seal and disinfect the soil. At the same time, rotate the crop to reduce the incidence. (2) Choose a healthy seed potato, do not plant seeds with diseased seed potatoes, and if necessary, cut the seed potatoes and dry them for 20 to 25 days. (3) At the beginning of the drug control, 70% thiophanate-methyl WP can be sprayed with 100% liquid plus 75% chlorothalonil wettable powder 1000 times or 70% thiophanate-methyl WP 1000 times plus 30%. % Copper Chloride Suspension 600 times, 40% Sulphur Suspension 500 times, every 10 days or so, control 1 or 2 times Ge (Tungia) leaf spot.
The micro circulation is by blood, the lymph and tissue fluid flowing which directly participates in the organization, the cell matter, the energy, the information transmission . May directly observe the blood flows in the thin artery, the blood capillary, and the thin vein through the micro circulation microscope , but if it does not do the special handling is that cannot see clearly the lymph and tissue fluid mobile, therefore, on clinical usually thought the micro circulation refers to the blood micro circulation in the blood capillary. Directly the blood, the lymph, tissue fluid flowing which participating in the matter, the information, the energy transmission of organization, and the cell , is called the micro circulation.
The Nailfold Capillaroscopy Microcirculation Microscope is an advance medical photoelectric apparatus,equipped with built in special LED light source,used mainly in observation on human nail fold capillary microcirculation or term as video Nailfold capillaroscopy,Such as capillary blood flow, abnormal microcirculation of the vascular structure, cell adhesion, through its powerful optical magnification. Undistorted, real time dynamic video streaming via Sony CCD imaging device onto the LCD monitor screen.

Simply insert the finger to the holder below the optical lens apparatus, fine-tune to fix the focal length and uncover the desired images within seconds.Blood capilliary microcirculation microscope is a non-invasive diagnostic tools, which is gaining large credit among physicians of different specialities in for study of skin blood capilliary network.
