Most of the symptoms occur in the base of the stem of the plant, forming dark lesions, which are slightly sunken after expansion. The diseased part produces filamentous hyphae, which are bundled into bundles and radiate to the upper part of the stem. The soil is moist, hyphae and even stem base. Develop along the soil surface. After the damage, the stem and root cortex of the diseased plant rotted, the xylem was exposed, the leaves were yellow, and the plants were wilting until the whole plant died.
Prevention and treatment methods 1. Implement rotation. Severely developed plots, with 4 to 5 years of rotation with gramineous crops, can work best with paddy fields, and can be effective once.
Second, strengthen field management. The diseased plant was removed in time, and the lesion was infused with 45% of a solution of 400% of a solution of ammonium water, or 250 ml of lime powder. After the tomato is pulled, clean the garden, deepen the soil, and apply lime powder 75-100 kg before the preparation of the soil.
3. After the onset of the disease, sprinkle pentachloronitrobenzene on the ground around the plant. That is, 70% pentachloronitrobenzene powder 0.5 kg, add fine soil 15 ~ 25 kg and mix well, apply 1 ~ 1.5 kg per acre, sprinkle once every two weeks, even sprinkle twice. Spray with 20% triazolone EC 2000 times solution, 35% methyl thiophanate suspension 500 times solution, 40% quintozene suspension 400 times solution or 50% mixed sulfur suspension 500 times solution. Spray once every 7 to 10 days to control the disease.
Humanized structure design makes installation and maintenance of lamps easier. The installation angle can be adjusted between -45°~75°, suitable for a variety of installation methods, mainly used for tunnel lighting, outdoor flood lighting, architectural decoration lighting, industrial lighting, sports centers and outdoor stadiums, ports, docks, etc.
