Symptoms mainly affect the leaves, stems and pods. The leaves became reddish-brown at the beginning of the disease, later became dark brown or black, and expanded into a polygonal reticular pattern. Petiole and stalk lesions were singulated and cracked, showing brownish rust-colored strips, and lesions forming slivers. The bean pods began to have brown dots at the beginning of the disease and expanded to brownish-brown-brown circles to form oval spots. The peripheries rose slightly, surrounded by reddish-brown or purple halo rings, and in the middle of the dents. When the humidity was high, pink viscous material was spilled. Contains large numbers of conidia. Seed spotted yellow-brown pits of varying sizes.
The pathogen, Colletotrichum lindemuthianum (Sacc. et Magn.) Br. et Cav., is called anthrax fungus, which is a fungus belonging to the genus Aspergillus. The conidia plate is black, buried under the epidermis, and then penetrates through the epidermis, round or nearly circular, with a size of 30-903-5 (μm). Scattered black spiny bristles on the disc. The conidiophores are short, single-celled, colorless and dense on conidia. Conidia are round or oval, unit cells, colorless, round at both ends or slightly narrow at one end, size 6-121-3 (μm), spores contain 1-2 nearly transparent oil droplets. The growth and development of germs is suitable for temperature 21-23°C, maximum 30°C, minimum 6°C, conidia 45°C and lethal for 10 minutes. In addition to invading mung beans, it also infects lentils, cowpeas, and broad beans.
Transmission routes and onset conditions mainly occur through the winter of mycelium lurking in seeds and attached to seeds. Sprouting seed with bacteria, seedlings infected, producing conidia on the cotyledon or young stems, spread by rain, insects. The mycelium can also cause winterization of mycelia in the diseased body, conidiospores in late spring, initial infection through rain splash, germination, conidial germ tube generation, invasion from the wound or direct, after 4-7 days of incubation Symptoms appear and reinfestation occurs. Temperature of 117°C and relative humidity of 100% are conducive to the onset; temperatures above 27°C and relative humidity below 92% are less likely to occur; conditions below 13°C stop developing. The disease is heavily planted in wet, dew, and humid cold and humid areas, and the wet weight of the soil is heavy under heavy soil.
Control methods (1) selection of disease-resistant varieties. (2) Use disease-free seeds or perform seed treatment. Note that seed is collected from disease-free alfalfa, or seed dressing with 40% seed weight of 50% carbendazim or thiram, 40% polysulfide suspension or 60% anti-seed Mildew ultrafine 600 times liquid soaking for 30 minutes, wash and dry sowing. (3) 2 years or more rotation. (4) After flowering, spray 25% carbon tetrachloride wettable powder 500 times or 80% Dasheng M-45 wettable powder 600 times, 75% chlorothalonil wettable powder 600 times, 70% methyl Sulfasalm (thiophanate-methyl) WP 500 times, 80% Anthraquinone omeprazole WP 800 times, 70% thiophanate-methyl WP 800 times 75% chlorothalonil WP 800 Double liquid, every 7-10 days 1, continuous control 2-3 times.
Laser Therapy Machine is a painless, no side effects physical therapy device. It can alleviate human pain effectively, accelerate blood circulation of the human body, and promote a high-cell oxygen carrying capacity. Common laser therapy wavelengths are 650 nm and 810 nm. Laser Therapy Machine is our company main product, Laser Therapy Machine include Laser Therapy Wrist Watch, Laser Pain Relief Machine and Laser Knee Massage.
Laser Therapy Wrist Watch:
The Laser Therapy Wrist Watch is an innovative 3-in-1 device that uses the latest research findings in the field of low-level-laser therapy. It combines acupuncture, local pain management and external blood irradiation and will become your ideal companion-whether at home, at work or on the go.
Laser Knee Massager :
Function Description:
• laser light:
[Mechanism] through the wavelength of 808nm, single laser output of the maximum power of 5mW laser irradiation of the nasal cavity or acupuncture points to the blood into a large number of photons, photons absorbed by blood cells and converted into internal energy, activation of blood cells, improve its ability to deform Oxygen-carrying capacity, improve blood flow and viscosity, improve blood rheology parameters, play to eliminate inflammation, reduce blood viscosity and lipid levels.
• LED red light rejuvenation:
[Mechanism] through the wavelength of 808nm, single laser output of the maximum power of 5mW laser irradiation of the nasal cavity or acupuncture points to the blood into a large number of photons, photons absorbed by blood cells and converted into internal energy, activation of blood cells, improve its ability to deform Oxygen-carrying capacity, improve blood flow and viscosity, improve blood rheology parameters, play to eliminate inflammation, reduce blood viscosity and lipid levels.
global mode corresponding function: air bag kneading + heating + laser irradiation + infrared.
Maintenance mode Corresponding function: air bag kneading + heating + laser.

Laser Pain Relief Machine :
Applications:
1. Pain clinic, such as soft tissue injury, heel pain, acute lumbar muscle sprain, scapulohumeral periarthritis, stiff neck, tennis elbow, cervical spondylosis, knee-joint disease of old-people, rheumatoid arthritis, neuropathic pain, wound healing, local infection, chronic pharyngitis, etc.
2. Women's Problems, such as pelvic inflammation, annexitis, dysmenorrhea, Inflammation of the vagina itch, mammitis, wound healing, etc (Note: hospital Laser Pain-Relief Instrument are more convenient for private place).
3. Skin disease, such as allergic dermatitis, thromboangiitis obliterans, 15 neurodermatitis, Herpes zoster and after herpes zoster pain, erysipelas, bedsore, eczema, cutaneous pruritus, etc.
4. Dermatology, such as swollen, cold injury, scald, acne, alopecia areata, alopecia, skin transplantation, etc.
Laser Knee Therapy Machine combines with laser light (650nm), LED light (630nm) and vibration technology to irradiate and massage on your knee and joint cavity. It improves microcirculation and metabolism in the related area, increase richer blood supply to tissues. In addition, it increases tensile strength of tissue repair, resolves inflammation, reduces edema and stiffness in joints, and gives pain relief.
Attention:
Laser therapeutic instruments are recommended to be used under the guidance of professionals.
