Be on guard against white silk disease

It rained all day on May 30. When we got up the next morning to take a closer look at each pot of orchids (this is my daily habit), I suddenly found that a pot of autumn lotus from the mountain was covered with white hair. The first reaction of the mind was a bad cry: "White silk disease" was immediately poured out, three new buds were cut off with a knife and washed with water, soaked with 500 times agricultural streptomycin for 15 minutes, and dried. Do not change the original plant material into a basin. Then mix the immortal soil with 500 times pentachloronitrobenzene, put the orchid seedlings on the pot, and then irrigate them with 500 times Jinggangmycin. Now it's basically under control for the past five days.

Think about it is too terrible, the spread of white silk disease is amazing, it will destroy the whole plant in a day or two, so I would like to remind you that the orchid pot should not be too wet during the mildew and rainy season, the plant material should not be too sour, ventilation is the key, and proper lighting should be given. Disinfect the whole orchid room with quicklime. (lan Huiming)
