At the turn of the spring and summer seasons, it is a season of mushroom diseases. Many mushroom farmers report that the good bacteria bags were destroyed by the disease overnight and suffered heavy losses. Here, the author summarizes the prevention and treatment experience of transactions in spring and summer, for the reference of the majority of farmers. Bacterial control All other microorganisms that are inconsistent with the biological characteristics of the inoculum (mushroom varieties or strains) are all bacteria. Common such as Trichoderma, Mucor, Aspergillus, Streptomyces, Rhizopus, Water Mold, etc. In addition to fungal fungus, there are some bacterial bacteria, all of which are harmful to the production of edible fungi. For germs, there are three main prevention and control measures: First, clean up the environment and destroy the breeding ground for germs. In addition to sanitizing the haystacks, garbage, and ditch around the production site, it is best to have no squat toilets, farms, etc. within 200 meters of the shed. If any, sterilizing must be done. Bacteria control can generally be sprayed with Sebastian 09 and used alternately with silly bugs to ensure preventive effects. Second, standardize the operation so that no bacteria enter the base material. It is mainly the sterilization and inoculation of strains or clinker cultivation. It requires standard operation and aseptic operation to prevent bacteria from entering the base material. Third, strictly ignore miscellaneous items and be vigilant to "net fish." Practice has proved that even if the conditions are good, experienced, and rigorous, it will inevitably lead to bacterial contamination in germs. Therefore, in the cultivation of bacteria and after-ripening culture, we must pay attention to the “check and miscellaneous†process, the purpose is to be in the base material. In the cultivation of high purity mycelium, lay a good foundation for mushroom. Disease prevention and treatment Any disease that may directly or indirectly cause harm to the fruiting body of the edible fungus, or produce some metabolites that are potentially harmful to the cultivation base or fruiting body, or is itself a productive pathogenic symptom of a certain pathogen, can be considered as a disease. In production, there are still some abnormal phenomena caused by improper human management, climatic reasons, or mechanical damage, which are called physiological diseases. There are three main pest control measures: First, sterilize the sheds and cut off the sources of diseases. The main approach is: mature bacteria stick into the mushroom studio before a week or so to conduct a thorough clean-up, and then use the sick silly 300-500 times liquid and Saibai 09 drug carpet alternately sprayed, sprayed once every other day. After application, it is sealed for 2-3 days, and conditions can be used for drying. The effect is better. Heating conditions can be increased to 35 °C, maintain two days, you can achieve the desired results. Second, effective prevention during fruiting. During the fruiting period, spray the medicine every 3-7 days to prevent the disease. The direction of drug use during fruiting is the wall, ventilation channels in the work lane and the booth, etc. Never make the drug contact the fruiting body, regardless of spraying or falling. Third, we must completely eradicate the disease. During the mushrooming period, it is necessary to inspect frequently and find that any infected fruit bodies and fungus bags (sticks) should be properly disposed of according to the disease conditions: just in time the disease should be promptly used to completely kill the pathogen, although the medication area is no longer mushroom, but Eradicate the disease at the first time to prevent the disease from continuing to spread. The disease 2 days after the onset of disease is still in its initial stage. If the proportion of diseased bacilli reaches 1%, the humidity should be reduced, ventilation should be increased, and then the drug should be used for treatment. On the basis of the above-mentioned dehumidification and ventilation, the disease on the 5th day of onset should be sprayed with two kinds of drugs, ie increasing the drug concentration to 300 times and 200 times, and increasing the density of the drug to 2-3 days once. The fulminating disease is fierce. If it is assessed that if it can be saved, all doors and windows can be opened on the basis of stopping the use of water, and the mushroom surface of the infected bacteria bag will be slightly destroyed, with 300 times more silly solution to all bacteria. The bags were sprayed one by one and sprayed continuously 3-4 times. Afterwards, the greenhouse shall be enclosed and left to stand for 2-5 days according to the temperature, and then the condition of the disease shall be checked. If no signs of disease continue, the mushroom will be re-emerged; if the disease condition of more than 10% of the bacteria bag still exists, the medication shall be continued. Until no more disease. If the disease is particularly serious, clean the shed should be handled. After pouring the base material, the organic fertilizer can be smashed.
We adopt a comprehensive classification method, which is divided by the ionicity of surfactants as follows which can all be provided by Insen Biotech: 1. Anionic surfactant: stearic acid, sodium dodecylbenzene sulfonate. 2. Cationic surfactant: quaternary ammonium compound. 3. Zwitterionic surfactants: lecithin, amino acid type, betaine type. 4. Non-ionic surfactants: fatty acid glycerides, fatty acid sorbitan (Span), polysorbate (Tween).
