One principle: prevention, prevention and treatment
The reason why the prevention in production is repeatedly emphasized is that the effect of prevention is far superior to that of treatment alone. In the production of edible fungi, investing a fund and energy for the prevention of pests and diseases is much better than investing three funds and energy. The so-called "preventing the problem" is reflected here.
In actual production, the "medical high temperature shack" method can generally be used to kill the pathogens in the mushroom shed, that is, after removing the coverings such as grass stalks, the sterilizing agent such as carbendazim is sprayed into the shed, and then the vents are sealed. Waiting for the sun to be exposed to the sun, the drug molecules move at high speed under high temperature, and are quickly released and decomposed under high temperature conditions, killing the bacteria quickly and efficiently, and degrading to the maximum extent to avoid residue. Generally, the new mushroom shed can be used to achieve the purpose once; the old shed or the area with the highest number of pathogens can be reused once every 2 to 3 days, and can be activated after two days of sealing.
Two concepts: the right medicine, high efficiency and low residue
The right medicine consists of two aspects. One is that the medicine should be symptomatic, and the symptom type is used to kill the disease. In actual production, many mushroom farmers do not care what disease, whether or not they are symptomatic, as long as they are said to be bactericidal, they are used, often because the medicine is not symptomatic, and the optimal prevention time is delayed, making "small lesions serious, A serious illness is a terminal illness." Second, the dosage of the drug should be appropriate, and the drug should not be used excessively. Generally, the range and concentration of disinfection medications for stockpiling and mushroom shed materials before seeding are relatively large. The concentration of the drug after sowing and before the mushrooming should be strictly controlled within the safe range, and the concentration of the fruiting body should be lower. For example, using phoxim and acaricide to control cockroach pests, 500 times before the stocking to the mushroom, and the concentration of 1000 times when the fruiting stage must be used.
Efficient and low-residence refers to the use of high-efficiency, low-toxic and low-residue agents to ban highly toxic pesticides. Commonly used fungicides are carbendazim, chlorothalonil, carbendazim, dexamethasone, methyl thiophanate, Bordeaux mixture, stone sulphur mixture and sulphur powder; commonly used insecticides are phoxim, dichlorvos and enemies. Hundreds of insects, pyrethroids, aluminum phosphide, chlorpyrifos, etc. Microbial preparations can also be used. Regardless of the mixing of materials, stockpiles or mushroom sheds, it is strictly forbidden to use organic mercury and organophosphorus agents with high toxicity and long residual period. Alternate application of different agents can prevent pathogenic bacteria and pests from developing drug resistance and reduce drug efficacy.
Three differences: the difference between inside and outside the mushroom shed, inside and outside the base material, prevention and treatment
In the mushroom shed, in addition to the nutrition of the base material, in addition to the Saibai 09 mixture, it should be sprayed once every 5 days during the period of hair growth and mushrooming to prevent the low concentration of the disease, Saibai 09, etc. The focus of medication is on the ground, walls and vents. It is not allowed to use the medicine directly. The shed can be sterilized with carbendazim and chlorothalonil.
Do not use carbendazim, thiophanate-based medicinal agents to prevent residue; stacking materials or mixing sites with the shed environment, can be treated with carbendazim, ketomycin and so on.
Preventive medication generally adopts a low-concentration and regular strategy, and after a disease occurs, it should adopt a high-concentration, one-time killing method to prevent resurgence, and the medicine can be selected as a silly, sterilized king.
