Carnation is most susceptible to leaf spot blight and rot disease. The spores of the leaf spot blight are found in the carnation plants and the decayed plants and spread through the air. When the surface of the plant has water for 8-10 hours, the bacteria can be wetted. Symptoms of leaf spot blight are: taupe leaves or spots with purple edges on the petals. The spots are clustered by black spores, and the stems begin to dry with yellow from the internodes and then develop to wilting around the stem. The pathogen of sputum rot remains in the old leaves, lower stems or rotted plants of carnation. High humidity conditions are conducive to the occurrence of pathogens. The symptoms are: first, it begins to rot at the tip of the flower bud, and then spreads to the base of the sputum. In addition to the removal of weeds around the carnation garden, in addition to the cultivation of carnation in greenhouses, the two methods must always supply air to the greenhouse to maintain low humidity. If irrigation is required, it should be carried out in the early morning. During irrigation, two plastic pipes are placed on both sides of the carnation seedling bed, and a flat fan nozzle is installed every 50 cm, and the angle to the ground is less than forty-five degrees. This will prevent the irrigation water from wetting the leaves of the flowers. During high humidity, spray or spray powder with daisen zinc, captan, mancozeb or sterilized.
