Blight is the main disease in the seedling stage. It occurs widely and the host is extensive. 1. Symptoms: The buds become brown and dead after infection. After the adult plant has been victimized, it begins to turn yellow from the lower leaves, and then the whole plant turns yellow and dies. After the bulbs were victimized, they gradually turned brown and irregular brown patches formed on the scales. 2. Incidence of disease: The bacteria can survive in the soil or in humus. Generally, it can survive for 2 to 3 years. It can spread under suitable conditions and infect young shoots with wounds or directly from hyphae. The suitable temperature for growth and development is 24°C. Humidity, poor ventilation, and lack of light are the main conditions for occurrence of blight. 3, control methods (1) The disease is transmitted by soil and rotation should be implemented. (2) Before sowing, the bulbs were impregnated with 1:500 Fomex solution, or impregnated with 40% formic acid solution and 50 times with water for 15 minutes. (3) Strengthen field management, increase phosphorus and potash fertilizers, make seedlings robust, and enhance disease resistance. (4) Spray 1:2:200 Bordeaux mixture 1 time before emergence, and spray 50% carbendazim 1000 times for 2 or 3 times to protect seedlings after emergence. After the onset, the diseased plants were removed in a timely manner and the wards were disinfected with 50% lime milk. leg massager with heat,leg massager machine,best leg massager,leg massager air compression,leg massage at home,leg massager best Shenzhen Urion Technology Co., Ltd. , https://www.urionhealth.com
