How to control diseases and insect pests by planting bamboo shoot after flood?

How to control diseases and insect pests by planting Dictyophora after disaster? The pathogens that often occur in Dictyophora cultivation after flood: slime mold, ash fungus, pests: slugs, termites, mites and so on. The control methods are introduced as follows for mushroom farmers' reference.

The main results are as follows: 1. Slime mold occurs on the bare soil or covered rice straw on the surface of Dictyophora border, which is sticky at the initial stage, will deform and move, showing milky white, orange and yellowish green, so that the growth of mycelium is affected or gradually disappears, and in serious cases, it no longer grows Dictyophora; the buds of Dictyophora are waterlogged and moldy. Prevention and control measures: strengthen ventilation. In the initial stage, carbendazim, 1000 times of thiophanate methyl, 500 times of copper sulfate and 10% bleach can be sprayed continuously for 3-4 times.

2. Botrytis cinerea often occurs in the environment of high temperature and humidity. In the initial stage, the dirty white fluffy hyphae appeared in the overlying soil layer of Dictyophora border, which soon turned pink and black, and the colony was dark smoke gray, and produced a large number of black spores. It mainly harms the hyphae of Dictyophora, causing the mycelium to break until death. Prevention and treatment: early appearance of dirty white villous hyphae is the best period for treatment, when 3% carbonic acid or 2% formaldehyde can be sprayed directly on the disease. When black spores appear, it can be sprayed with a 700-fold dilution of formalin (70%) and thiophanate methyl (70%). In severe cases, cut off the culture material around the affected area, sprinkle fresh lime in and around the affected area, and cover the affected area with plastic film to control its spread.

3. Slug is a mollusk, commonly known as "slug". It has no shell and has an exposed body. it mainly engulfs the ball of Dictyophora, causing the ball to perforate and leaving a white mucus. Prevention and treatment: trap and kill with 1:50:50 calcium arsenate, wheat husk and water in places infested by slugs, or spray 5% coal phenol soap solution and 50% salt water in places infested with slugs.

4. The common termites harmful to Dictyophora are house termites, black-winged termites and yellow-winged termites. Can eat the hyphae of Dictyophora, affecting the yield of Dictyophora. Control method: pursue the ant nest and the main ant road, use 80% arsenite, 15% salicylic acid and 5% iron oxide to form a poison, spray 6-15g per nest and the whole nest will die.

Mites are easy to break out at high temperature and humidity, and occur in both the mycelium growth stage and the mushroom stage, which can bite off the hyphae, shrink the hyphae, bite the Dictyophora ball and spread germs, resulting in a bad harvest. Control method: spray 2.5% Uranus 2000 times solution or other special acaricides.
