Xu Dongsheng: how to treat Bayras disease

Bellas virus disease, although judged as an incurable blue disease, is not absolute. In fact, orchid gardeners and growers everywhere have made some progress in the treatment of Ballas disease orchid. The author also conducted an experiment on the treatment of a cluster of orchid seedlings suffering from viral diseases. After 3 years, the old strain has withered, and the three new strains germinated have no symptoms of virus disease. Although it has not been examined by tissue section, it is not certain that it is cured, but the recent surface control can be said to be successful. The method of treatment is:

(1) breeding plants should create suitable ecological conditions to cultivate infected orchid plants, and do not put them in glass greenhouses. According to the habits of orchids, it is necessary to adjust light, temperature and humidity, more natural wind, and appropriate supply of fertilizer and spraying, so as to strengthen plants and improve resistance.

(2) to inhibit and eliminate virus, spraying and spraying should be carried out in both ways, spraying to treat the aboveground part, pouring medicine to treat the underground part, and carrying out omni-directional treatment. Spray once every 7 days, once every 10 ~ 15 days, after 10 ~ 15 times, change to once every half a month or once a month for more than one year to consolidate the curative effect. The agents used in the treatment were as follows: the finished pesticide of ① was 500 times of virus Bike, and 250 times of edible rice vinegar with strong human osmotic function was added to introduce the medicine directly to the disease department to enhance the efficacy. In addition, nutrients rich in amino acids and other ingredients are taken to enhance the ability of orchid plants to dispel pathogens. ② was treated with heat-clearing and detoxifying traditional Chinese medicine with antiviral function. Such as Radix Isatidis, Daqing leaf, honeysuckle, Guanzhong, Huanglao, quilt, one see Xi, seven leaves a flower, Scutellaria barbata, Scutellaria barbata and purple flower underground, are the first choice of medicinal materials. You can choose a combination of three or five flavors and use them alternately every month. First use the leaching solution, then use the boiled solution, and then sprinkle with the residue. The suitable solution is 10 ~ 100 times. ③ was sprayed with 1000 times solution of antipyretic and analgesic aspirin once a season to induce plants to produce resistant proteins to inhibit or kill the virus. In doing so, there is considerable synergy.

(3) Fuzheng and dispelling evil orchid plants consume too much, and they are unable to transport drugs to dispel evil, so Fuzheng is indispensable. The main measures for strengthening the upright body are as follows: ① gradually increasing the amount of light, ② more natural wind, more bath dew, ③ fertilizing normally, applying compound trace element fertilizer or plant biotics once a year, spraying medium concentration foliar fertilizer once a week or half a month, such as plant power 2003, Galida, Gaole, Aishi brand foliar fertilizer and so on. If we can make unremitting efforts in accordance with the above methods, we may be able to achieve the effect of short-term cure, or at least the effect of controlling its spread.
