Causes of Button Mushroom Death and Detailed Control Methods

The button mushroom (Agaricus bisporus) is one of the most commonly cultivated edible fungi in China. With the continuous development of cultivation technology, the yields from greenhouse and factory cultivation are also relatively high. But for growers, the most feared thing is the occurrence of various diseases and dead mushrooms in button mushrooms. What causes this? Let's take a look together.

I. Causes of Button Mushroom Death

There are many causes of button mushroom death, such as sustained high temperatures, long-term nutrient deficiency, poor ventilation conditions, improper watering, unsuitable soil pH, mycelial aging, high mushroom density, pest and disease infestation, and improper pesticide use. These factors can all cause button mushroom death, and they are all relatively common during the button mushroom cultivation process.

II. Control Methods

1. Select superior spawn

Spawn selection is a key point in growing button mushrooms. Only spawn with good mycelial growth capacity has a relatively high possibility of achieving high yield after planting, and it can also excellently prevent the phenomenon of dead mushrooms. In addition, attention should be paid to the sanitation of the culture room, keeping the air fresh. During the spawn cultivation period, pay attention to the temperature inside the mushroom shed, and be sure to let it grow at a suitable temperature. Once inferior or poorly growing spawn is found, it must be disposed of in time.

2. Master the correct planting time

Button mushrooms are widely cultivated in China, so the planting time should be determined according to the local climate and geographical environment. For example, in North China and Central South China, cultivation materials are generally prepared in August, and sowing is carried out in September. Planting too early or too late is not conducive to the growth of button mushrooms, and the phenomenon of dead mushrooms is very likely to occur.

3. Do a good job of ventilation

During the growth of button mushrooms, sufficient oxygen must be maintained. If the indoor carbon dioxide concentration is too high, it may cause the fruiting bodies of button mushrooms to be unable to grow and develop. If the carbon dioxide concentration continues to rise, then the possibility of button mushroom death will be very high.

4. Use water correctly

The watering amount for button mushrooms must be determined according to factors such as climate and mushroom yield. It should not be too much or too little. If there is long-term rainy weather, then pay attention to the watering amount, and also spray very little water or no water. If it is a high-temperature summer season, because evaporation is large and the air is relatively dry, it is necessary to spray appropriately more water to play a role in cooling and humidifying.
