One principle: focus on prevention, prevention and treatment
The reason why prevention is repeatedly emphasized in production is that the effect of prevention is far better than that of prevention alone. In the production of edible fungi, investing a fund and energy in the prevention of pests and diseases is more effective than putting in three funds and efforts to control the disease. The so-called “preventive measures†benefits are reflected here.
In actual production, the “drug high temperature stuffy shed†method can be generally used to kill pathogens in the mushroom shed. After removing mulch and other coverings from the shed, spray fungicide such as clotrinone in the shed and close the vents. Such as, so that it receives the sun, in the role of high temperature, the drug molecules high-speed movement, and quickly released and decomposed under high temperature conditions, rapid and efficient kill bacteria, and can be the maximum degree of degradation, to avoid residue. Generally, the mushroom shed is newly constructed, and once the medicine is used, the purpose can be achieved. In areas with high sheds or bacterial bases, the medicine can be used every 2 to 3 days. After two days of confinement, it can be used.
Two concepts: remedy, high efficiency and low residual
There are two aspects of the remedy. The first is that the medicine should be symptomatic, and for the types of diseases that occur during production, the symptomatic agent is used to kill it. In actual production, many farmers do not care about disease, and whether or not they are symptomatic. As long as they are sterilized, they are often used because they are not suitable for the disease, but they delay the optimal timing of prevention and control, making small lesions serious. Severe illness became terminal illness." The second is that the amount of the agent should be appropriate and not be overdose. In general, the range of application and concentration of disinfection material and stock material before planting are relatively large. After sowing and before mushrooming, the drug concentration should be strictly controlled within the safe range, and the fruit body stage concentration should be lower. If phoxim plus acaricides are used to control acarid pests, they should be used 500 times before stockpiling and fruiting should be reduced to 1000 times when fruiting stage must be used.
High-efficiency and low-residue refers to the use of highly effective, low-toxicity, low-residue pharmaceuticals and banned highly toxic pesticides. Common bactericides include carbendazim, chlorothalonil, clotriaxacin, dexamethasone, thiophanate-methyl, Bordeaux mixture, lime sulfur and sulfur powder; commonly used insecticides include phoxim, dichlorvos, and Hundred insects, cypermethrin, aluminum phosphide, and chlorfenone. Microbial preparations can also be used. Whether it is mixing, stacking or mushroom shed prevention and control, it is strictly prohibited to use highly toxic and long-lived organic mercury and organic phosphorus agents. Alternate application of different agents can prevent germs and insects from developing resistance and reduce efficacy.
Three differences: inside and outside the mushroom shed, inside and outside the base material, the difference between prevention and treatment
Mushroom shed medication, in addition to the deployment of base nutrition, with 100 races, but should be sprayed every 5 days during the fungus and mushroom spraying a low concentration of silly, Saibai 09 to be prevented, Medication is mainly on the ground, walls and vents, etc., and direct use of the drug should not be applied to the fruiting body; outside the shed, carbendazim, chlorothalonil and other agents can be used for sterilization.
Don't use carbendazim or thiophanate-fungicides in spices to prevent residue. Stacked materials or spices can be treated with carbendazim or clotrimazole.
Preventive use of drugs generally take a low-level, regular strategy, and the occurrence of disease, it should take a high concentration, one-time killing methods to prevent the resurgence of fire, the drug can choose all kinds of silly, decontamination king and so on.
