Black spot Black spot is a bacterial disease caused by Pseudomonas. After onset, mushroom cap appeared oval brown or dark brown spots, the beginning of the needle-like, expanded diameter of 2 to 4 mm, the edge of the neat, sometimes cap cracking. The prevention methods are: 1. The key is to control the appropriate temperature and humidity. Mushrooms to the sprinkler, the water can not be sprinkled directly on the fruiting bodies of mushrooms, to prevent spraying with cold water. Mushroom room humidity should not exceed 90% for a long time, depending on the weather changes sprinkler, sunny sprinkler to light, diligent, fine. 2. Rainy days to sprinkle less or sprinkler. After each sprinkler to enhance ventilation, and then cover the film. 3. fruiting period should be adjusted to indoor temperature below 17 ℃. 4.
