In the production of edible fungi, the chemical and chemical control of pests and diseases should be strictly followed, and the principles of safe use of pesticides should be strictly followed to ensure the safety of the products and the personal safety of the applicators.
First, know medicine selection
Before using the edible fungi, you should be familiar with the nature of the pesticide. You should understand the difference between the two major categories of pesticides and fungicides, which are used to control pests and diseases, and cannot be exchanged. Acaricides are not a substitute for nematicides. Be familiar with the physical and chemical properties, functional characteristics, methods of use, concentration and spraying time of pesticides.
Second, the right medicine
The edible fungus produces eyelid mosquitoes and fecal mosquitoes. The 500-fold trichlorfon in the shed has special effects on adults and larvae of the mushroom flies, but it has poor killing power to the mites. Pleurotus ostreatus is sensitive to dichlorvos. If the concentration is slightly higher, it may cause phytotoxicity. It is best to use trichlorfon or phoxim. Agaricus bisporus is sensitive to trichlorfon, it is best to use dichlorvos. If there are mosquitoes and mites at the same time, the effect of mixing with phoxim and acaricide is better.
Third, the use of reasonable concentration
In the production of edible fungi, the concentration of the drug should be determined according to the different growth stages of the drug type, pests and diseases, and edible fungi. Generally, the range and concentration of disinfection medications for stockpiling and mushroom housing materials before seeding are relatively large. The dosage 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, phoxim plus acaricides can control pests such as mites, and 500 times of liquid is used before stocking, and the fruiting stage must be reduced to 1000 times when used.
Fourth, the banned pesticides in the mushroom period
Pay attention to prevention before the mushroom, and create an excellent environment for the growth of edible fungi, and enhance its own disease resistance. When you have to take the medicine, you should choose it before the mushroom is taken, or you can pick it up. Because the cultivation period of edible fungi is short, the drug is likely to remain and cause food poisoning, which in turn will have a serious impact on the circulation and consumption of the product. Moreover, these pesticides can also cause phytotoxicity to edible fungi.
5. Use high-efficiency, low-toxic and low-residue agents
Select high-efficiency, low-toxicity and low-residue agents, and disable the fungicides commonly used in highly toxic pesticides: carbendazim, chlorothalonil, ketomycin, daisen zinc, methyl thiophanate, Bordeaux mixture, stone sulphur mixture and sulphur powder. Commonly used insecticides are phoxim, dichlorvos, trichlorfon, chlorpyrifos, aluminum phosphide, and chlorpyrifos. Microbial preparations can also be used. Whether it is mixing, stocking or mushroom house control, it is strictly forbidden to use highly toxic, long-lasting organic mercury, organic phosphorus and other agents. The use of different agents can avoid the resistance of bacteria and pests and reduce the efficacy.
Sixth, pay attention to protect personal safety
Phosphine has a strong penetrating power of phosphine formed by water, and has good control effect on eyelid mosquitoes, fecal mosquitoes, hoppers, nematodes, etc., and has no residual toxicity, but it is toxic to humans and must be worn during fumigation operations. Protective mask, the operator must have more than 2 people to ensure personal safety.
