How to prevent and control pests and diseases after bamboo fungus cultivation is flooded? Please give guidance
The pathogens that commonly occur in bamboo fungus cultivation after flooding: slime molds, sooty mold fungi; pests: slugs, termites, mites, etc. The control methods are introduced below for mushroom growers' reference.
1. Slime molds occur on the exposed soil of the bamboo fungus bed or on the covering rice straw. In the early stage they are sticky, can deform and move, and appear milky white, orange-yellow, or yellow-green, causing mycelial growth to be inhibited or gradually die out; in severe cases, bamboo fungus no longer grows; affected bamboo fungus primordia become water-soaked and rot. Control measures: strengthen ventilation. In the early stage, carbendazim, 70% thiophanate-methyl at 1000 times, copper sulfate at 1:500, or 10% bleaching powder can be sprayed continuously 3-4 times.
2. Sooty mold fungi often occur in high-temperature and high-humidity environments. In the early stage, dirty-white cottony mycelia appear on the casing soil layer of the bamboo fungus bed, quickly turning pink and black; the colony becomes dark sooty gray and produces a large number of black spores. They mainly damage bamboo fungus mycelia, causing the mycelia to break and eventually die. Control method: the early appearance of dirty-white cottony mycelia is the best treatment period; at this time, 3% carbolic acid or 2% formaldehyde can be sprayed directly on the affected area. When black spores appear, 20 times formalin plus thiophanate-methyl (70%) wettable powder at 700 times dilution can be sprayed. In severe cases, cut off the substrate around the affected area, spread fresh lime on and around the affected area, and cover the affected area with plastic film to control its spread.
3. Slugs are a type of mollusk, commonly known as "snails without shells." They have no outer shell, their bodies are exposed, and they mainly devour bamboo fungus primordia, causing perforation of the primordia and leaving a trail of white mucus. Control method: use 1:50:50 calcium arsenate, wheat bran, and water placed where slugs appear for trapping and killing, or spray 5% cresol soap solution or 50% salt water where slugs appear to kill them by dripping.
4. Termites. The termites commonly damaging bamboo fungus include Coptotermes formosanus, Odontotermes formosanus, and Macrotermes barneyi. They can bore into and feed on bamboo fungus mycelia, affecting bamboo fungus yield. Control method: trace the ant nest and main ant routes, and apply a poison made of 80% arsenious acid, 15% salicylic acid, and 5% iron oxide; spraying 6-15 g per nest can kill the entire nest.
5. Mites are prone to outbreaks under high temperature and high humidity. They occur during both the bamboo fungus mycelial growth stage and the fruiting stage. They can bite off mycelia, causing the mycelia to shrink and stop growing, and can also bite bamboo fungus primordia and transmit pathogens; in severe cases they cause total crop failure. Control method: spray 2.5% fenbutatin oxide at 2000 times dilution or other specialized acaricides.
