What do I do if mycelium is contaminated?
If spotted early, you can control cobweb mold and salvage your grow using hydrogen peroxide. Hydrogen peroxide (H2O2) spray is a great weapon in the battle against mold because it will not harm your mycelium but will kill any mold and/or spores trying to take over your monotub. So spray, spray, spray away.
How do you tell if your mycelium is contaminated?
If you spot green, blue, grey, or black patches on or in your fruiting box, your culture is most likely contaminated. Do keep in mind, however, that small blue stains in the mycelium may just be bruising and not mould. Especially where the rye presses the mycelium against the grow box, you may see some blue spots.
How do I get rid of mushroom contamination?
If it’s a small patch but mushrooms are already growing: Ideally, if you have it available, spray the small patch of mould with isopropyl alcohol (rubbing alcohol) to kill it before removing it. If you don’t have isopropyl alcohol, don’t worry, just be careful not to touch it or disturb it as it may release spores.
How do you prevent bacterial blotches?
Adding sodium hypochlorite at 150 ppm chlorine to water used in irrigating the crop will control blotch, providing the mushrooms can be kept dry. But if the mushroom stays wet, chlorine has little effect since the bacterial population reproduces at a rate that neutralizes the effect of the oxidizing agent.
What does contaminated mycelium smell like?
The growing mycelium should give off a clean mushroomy smell (similar to the end fruiting product), it should be mild and not overwhelming. Any foul or strong smells should be observed in an attempt to discover whether your substrate is contaminated. Note: Oyster mushroom mycelium will smell like aniseed or liquorish.
How do you disinfect a mushroom house?
Therefore, to be safe and avoid any possible migration of chemicals into the room, it is best to use a FCS chemical or soap and water that would not be a food safety concern.

Is mycelium supposed to be fuzzy?
Mycelium can look fuzzy to thread-like or both at the same time. This is a very dense population of mycelium, however, you can hopefully see the water droplets sitting on the mycelium.
What is leaf blotch disease?
Leaf blotch damages young bermudagrass seedlings or adult plants that are weakened by factors such as excess thatch, nitrogen deficiency, and other unfavorable growing conditions. The disease attacks during cool, wet weather, with symptoms usually seen from late autumn to spring.
What is mushroom disease?
Verticillium fungicola), is one of the most common and serious fungal diseases of mushroom (Agaricus bisporus) crops. Traditionally, the bacterium Pseudomonas tolaasii has been considered the main causal agent of Bacterial Blotch or Brown Blotch, although it has also been linked with P. reactans.
