Orchid Medication Knowledge, Part Five: Getting to Know Hydromycin

In nature, living organisms interact, balance one another, and both promote and restrain each other, sustaining the continuation of life. In the process of life's continuation, microorganisms play a very important role. When organisms flourish, microorganisms are needed to create nutrients through decomposition; when organisms die, microorganisms are needed to turn decay into something wondrous. So-called microorganisms are what we commonly call fungi. From the human perspective, fungi can be divided into beneficial fungi and pathogenic fungi. The pathogens of infectious plant diseases are: fungi, bacteria, actinomycetes, mycoplasma-like organisms, viruses, viroids, and so on. The famous antibiotic agents through which people use beneficial fungi to control pathogenic fungi include penicillin, streptomycin, chloramphenicol, gentamicin, and others. This article introduces a new type of fungicide to everyone - Hydromycin. Hydromycin is a new high-tech fungicide recently created and exclusively produced by a certain pesticide factory in Sichuan. It belongs to the antibiotic class of pollution-free biological pesticides. It has special efficacy against bacterial diseases of crops such as melons and fruits and vegetables, and can also concurrently control fungal diseases and viruses of melons, fruits, and vegetables, and can enhance the disease resistance of crops. Hydromycin is a professional bactericide, with a specific killing effect on bacteria, and its bactericidal effect is even more prominent on crops that have long used streptomycin. It is not prone to inducing resistance, belongs to biological agents, has no cross-resistance with other fungicides, and has remarkable control efficacy against bacterial diseases that have developed resistance to currently used fungicides. It is convenient and safe to use, and can be mixed with other agents except strongly acidic and strongly alkaline pesticides. In addition to spraying, it can also be used as a root drench or splash irrigation treatment. When applied at the recommended dosage, it will not cause phytotoxicity. This April is precisely the high-incidence period for soft rot and stem rot. Yaoyuan, in order to prevent and controlsoft rotdisease, often ran to the nearby pesticide station to ask questions, so the service staff at the pesticide station recommended to Yaoyuan Hydromycin, which has special efficacy in controllingsoft rotdisease. Hydromycin is packaged in common small medical penicillin vials, with very good sealing, ensuring it can be used within its shelf life. Each vial contains 5 grams, and the price is only 2 yuan, belonging to the inexpensive category of pesticides. According to the instructions, each vial can be diluted with 15 kilograms of water; the calculated ratio is 3000 times. For use onorchidsfor prevention, it can be 2000 times; if used for treatment, the dosage needs to be appropriately increased. Prevention is primary; when used in the early stage of disease onset, it can control the development and spread of the disease. Spray once every 7-10 days, for 2-3 consecutive sprays. In the past, Yaoyuan mostly used drugs such as streptomycin to deal with bacterial diseases likesoft rotdisease. As the frequency of use increased, bacteria would develop antibodies, so the drug concentration had to be increased to achieve control effects. New drugs often have special efficacy against pathogens that have already developed antibodies to a certain drug, and the dosage need not be very large. Alternating the use of several different drugs is a principle we should follow. According to the introduction, Hydromycin is very safe for crops, and applying it at any stage of crop growth will not cause phytotoxicity. It is also said that long-term use can resist infection by external pathogens (perhaps this is only promotional, as it has not been confirmed due to the short time it has been in use). Using drugs is a last resort; the emphasis should be placed on prevention. Currently, drugs for preventing and controlling fungal and bacterial diseases are effective in prevention, but in treatment they must be somewhat discounted. As the saying goes: "Illness comes like a landslide, but goes away like drawing silk thread." Even if the disease is cured, the road to recovery is still: long and far, oh so distant. (Gao Haiyong)
