Prevention measures: after each watering, open the doors and windows for 30 to 60 minutes to ventilate.

What are the control methods for mushroom rust spot disease?
Mushroom rust spot disease, also called brown spot disease or bacterial blotch, is caused by Pseudomonas tolaasii, an acidophilic species of the genus Pseudomonas. It spreads through insects, tools, the hands of workers and other carriers. The disease is severe when the casing soil of the mushroom bed has a pH below 5.5, when ventilation is poor, when humidity is too high, and when the mushroom caps remain constantly moist and sticky after watering. Its symptoms are: it generally infects only the epidermal layer of the mushroom cap, causing spots of varying size that are initially yellowish-brown and rust-like in appearance, which later gradually turn brown or black, and sometimes scars with mucus also appear on the caps.

How to prevent rust-colored spots on mushroom caps
This is generally caused by failing to open doors and windows promptly for ventilation after watering, which makes the humidity in the mushroom house too high; water droplets then collect on the cap surface for a long time, producing rust-colored spots in localized areas. Rust-colored spots resemble bacterial spots, but they are limited to the surface. Preventive measures: open doors and windows for ventilation on schedule or when the weather is suitable, bring in fresh air, and evaporate the moisture on the surface of the mushrooms.
