The latest control methods of Streptomyces lucidum
Streptomyces is also known as Alternaria oryzae, Alternaria, etc., the hyphae are transparent, branched, multi-septum, and loose, reticulate, conidiophores grow from the hyphae and produce conidia at the top of the conidiophores. The main species are Alternaria oranges, Alternaria, Alternaria, Alternaria and so on. Let's take a look at the control methods of Alternaria lucidum.
Incidence regularity of Ganoderma lucidum Alternaria
The main results are as follows: 1. Alternaria is widely distributed, lives on organic matter and spreads through airflow. The main ways of primary infection of Neurospora are unsanitary site, poor aseptic condition, incomplete sterilization, wet and loose cotton plugs and sand holes in bacterial bags. Once infected, the new conidia produced is the way of re-infection.
2. Streptomyces has strong growth activity, likes high temperature and humidity, and grows rapidly when oxygen is sufficient. It can grow in 4-44 ℃, and the fastest growth is in 25-36 ℃. When the water content of the culture material is 53 ~ 67%, pH3~9 can grow rapidly. The hot season is a period of high incidence.
Damage characteristics of Streptomyces lucidum
1, the momentum is fierce, spread quickly, the harm is very great, once occurs, it is difficult to control, generally carry on burial or incineration.
2. Conidia germinate faster than other mold hyphae.
3. The aerial mycelium has strong resistance and can penetrate the cotton plug and break the bacterial bag.
4. The damage of Alternaria is rampant in the summer with high temperature and humidity, which mainly spreads rapidly at the mouth of the culture bag and the root and edge of the fruiting body, producing a large number of orange powdery spores.
Control methods of Ganoderma lucidum Alternaria
1. The culture material should be fresh without caking and mildew, exposed to the sun before use, and sterilized thoroughly to prevent the cotton plug from getting wet and reduce the damage to the strain bag.
2. The training ground, bed frame, wall, etc., are sprayed with 500 times 70% methyl topiramate solution.
3. For mild cotton plug infection, under aseptic condition, the bottle mouth and cotton plug are burned and sterilized by flame, and the cotton plug is dipped with lime powder and put back to the original place. If the cultivation bag is polluted but the mycelium vitality of Ganoderma lucidum is still very strong, you can dig 30-40 cm in the shade, drain the bag and cover it with wet soil, and the fungus will disappear in about half a month. In case of serious pollution, burning or deep burial should be removed in time to prevent conidia from spreading and infecting again.
4. Once the orange-red conidia appears, carefully wrap it with wet cloth or wet paper, soak it in the liquid or bury it deeply. Do not spray the bacteria directly with a sprayer to prevent the spores from flying.

Trichoderma viride has the highest frequency and harm, and can occur in all stages of Ganoderma lucidum cultivation. It can be described as devastating and catastrophic diseases and miscellaneous bacteria, which seriously affect the yield and quality of Ganoderma lucidum. It is the focus of disease control in Ganoderma lucidum cultivation.

Ganoderma lucidum yeast is a kind of ascomycetes without filamentous mycelium structure, which is widely distributed in nature. Ganoderma lucidum, Tremella fuciformis and other edible fungi can pollute the culture medium and culture materials in the process of production and cultivation, mainly polluting the culture materials, causing the culture materials to deteriorate and inhibit the hyphae.
