Stem rot and soft rot can be judged visually, and prevention must start early

Stem rot andsoft rotcan be judged visually, so prevent them early!
For half-year-old new seedlings and adult plants during the growing period, stem rot and soft rot are generally not easy to spot right away, and by the time you do see the problem it is already too late, leaving you no choice but to painfully pull up the still-green seedlings that show no change in color, which is heartbreaking! Is there any way to predict it in advance and detect the disease early? Based on my years of practical observation, there is a way, and as long as you observe carefully it is not hard to notice! Of course, you need more than 2 orchid pots for comparison. When you find that the surface of one pot does not dry out for 2-3 days, while the surface of other pots has already dried completely and turned white, that is a sign of soft rot and stem rot. At this point the orchid roots no longer have respiratory or absorptive function, and instead show a water-soaked "reverse osmosis" phenomenon, which is reflected on the pot surface as being constantly wet and never drying! If you smell it with your nose, there is a strange odor (similar to a moldy smell)! At this time you must immediately pull back the potting medium on the surface to check. A conservative treatment is: pull back the medium to expose the pseudobulb and part of the roots, let them dry in the wind, do not water even a drop for 3 days, and after they are completely dry use Bingchongqing and carbendazim to drench the roots 1-2 times; you can also use chloramphenicol eye drops to drip-irrigate the affected pseudobulb. If necessary, knock the plant out of the pot to check, remove the rotted roots, and soak in a 1/1000 potassium permanganate solution for more than 1 hour. After thoroughly air-drying, repot with clean potting medium and keep it in shade for more than a week, during which you should still withhold water and maintain dry care. This is the best approach.
