Pleurotus ostreatus culture material can add carbendazim
Inquiries: I am a farmer in Tianshui. I recently saw online that Pleurotus ostreatus was not effective in adding carbendazim when it was used to mix ingredients, and it also made the mushroom mycelium short and increased pollution. Will carbendazim be added to the mix?
Answer: The statement that there is no effect has a long history. The reason for this is that, first of all, it is subjective that carbendazim will be decomposed during high-temperature sterilization, so there is no effect. Actually, carbendazim decomposes at 306°C. Not to mention that ordinary sterilizers used by our peasants, including autoclaves, cannot reach this temperature during use. Therefore, high temperature failure is not credible. Second, there is a problem with the use of methods, carbendazim in alkaline environment is easy to break down, so can not use lime and carbendazim at the same time, at the same time, we must also pay attention to, carbendazim easy to make bacteria resistant, so Long-term use should be avoided, and other fungicides such as clotrimazole can be used interchangeably. Carbendazim has a good effect on green molds, but it has poor effects on mucor such as mucor and rhizopus, so it is necessary to select the types of agents for the types of fungi that occur.
As for the inhibition of mycelial growth, first of all, if we do not increase the dose without our recommended amount of use, there must be an inhibition of mycelial growth. Second, if you produce edible fungus species such as fungus, hedgehog fungus, and white fungus, these species are particularly sensitive to carbendazim, and there will certainly be suppression. Therefore, you must not use it.
In terms of safety issues, we recommend using 40 to 50 days of inoculation and germination during the seasoning. Therefore, it will definitely exceed the safe interval before mushrooming. In addition, the amount used is very small, and it will not cause any residues exceeding the safety regulations for the products produced.
Specific to the mixing process, if you use raw materials that are fresh, there is no mildew, and then sterilization equipment sterilization effect is good, you can not use it. However, if it is to reduce costs, raw materials are mixed with mildew or raw materials that have been infected by bacteria, combined with sterilization at normal temperature and pressure, in order to reduce the fungal infection rate of bacteria bags, it is best according to our recommendation Methods Correct use of related agents.
