Causes and Control measures of Auricularia auricula

The phenomenon of auricularia auricula is easy to occur in the process of cultivation, which leads to a decrease in yield and no harvest, which seriously affects the economic benefits of growers, so the prevention of auricularia auricula can significantly improve the economic benefits. Let's take a look at the detailed introduction with the editor.

1. Symptoms

When auricularia auricula occurs, the damaged ear slices will appear light yellow or brown in the early stage, the surface will be sticky, and will be accompanied by a fishy smell, and the whole fungus will rot in the later stage. Most of them are caused by nematodes and bacteria, among which nematodes are the main cause of auricularia auricula phenomenon. Nematodes suck the juice of fungus cells and tissues, and the toxins of its excreta can directly harm Auricularia auricula, leading to fungus infection and decay.

2. The cause of disease

In addition to nematodes, management factors are also the cause of auricularia auricula. When Auricularia auricula is mature, it will continue to conidia and consume the fruiting body, which makes the fruiting body tend to aging, which will be very easy to rot in case of high humidity. In the unsuitable temperature environment, ear flow phenomenon will also occur. When fungus is a high-temperature edible fungus, it can grow normally between 22 and 34 degrees Celsius, which requires higher humidity, but it is also a period of rapid propagation of nematodes. If the environmental hygiene is poor, the reproduction speed of nematodes is accelerated, and the phenomenon of ear flow is easy to occur. During cultivation, the ear shed is poorly ventilated, resulting in excessive concentration of carbon dioxide, which reduces the vitality of ear fungi, slows the growth of fruiting bodies or stops growing. At the same time, it provides a favorable breeding environment for bacteria, nematodes and microorganisms.

3. prevention and control measures

To do a good job in cooling measures at high temperature, we can close the shed windows during the day, spray water mist to cool down, strengthen ventilation at night, and control the temperature within 30 degrees as much as possible. In this temperature environment, Auricularia auricula grows very fast. And it will also inhibit the reproduction rate of nematodes. The ear shed ground should have a certain slope, and the topsoil should be sandy loam soil to avoid water seepage, and the clean water source should be deep well water. When the ear-flowing phenomenon occurs, first remove the ear-flowing ears, spray low concentration of salt water, and at the same time spray lime water on the ground to control the spread rate of nematodes, and fumigate with aluminum phosphide for 24 hours.

The above is the introduction of the causes and prevention measures of Auricularia auricula. I hope it can help you. If you want to know more about it, please follow us.
