Recently, when the author interviewed ancient cities in Shouguang City, Sunjiaji Subdistrict, and Qingzhou City, many vegetable growers who reflected on sweet peppers reported that the recent phenomenon of bad culms was very serious and caused serious dead trees. The author observed the symptoms of sweet pepper rotten stalks in several sheds and found that it was mainly caused by two kinds of diseases. Some plants were mixed with two diseases to cause rotten stalks. At present, bacterial rot and gray mold are mainly caused by the occurrence of rotten stalks in sweet peppers. First, bacterial soft rot disease. The main damage to fruits and stalks, from the wounds caused by the pruning began to infect the diseased part of the primary water-immersed dark green spots, after the brown soft rot, the surface of the disease after the decay of the membrane, and the disease more than a bad smell Taste, it will fall off in case of external force. Seedling disease also began to get infected from the wound. It was soft and rot-like in water, and eventually the seedlings died. Second, gray mold. The pathogenic factors of gray pepper mold are various. Low temperature and high humidity are the characteristics of early spring climate. The optimum temperature for pathogenic bacteria is 23°C. In addition, current vegetable farmers do not release the water in time, watering is too much, and the humidity in the greenhouse must be high. It is the main cause of the gray mold epidemic. Some vegetable farmers put prevention and control on the prevention and control of disease and powdery mildew. The drugs used can not cure gray mold and miss the timing of prevention, leading to the current outbreak of gray mold. Both of the above diseases are like high humidity environment. Reducing the humidity in the greenhouse is the key to prevent and control these two diseases. Coverage is through plastic film, control of watering, timely release of air, aerosol and dust agent prevention and treatment, spray prevention and treatment as a supplement. Measures to reduce humidity. If the above two diseases are mixed, it is recommended that the farmer use agricultural streptomycin or methamphetamine and prophylaxis spray or spray.
