Stem rot and soft rot can be judged intuitively, early prevention!

During the growing period, half-age new seedlings and adult seedlings, it is generally not easy to observe stem rot and soft rot diseases immediately, and so on to see that the problem is already too late, so I have no choice but to give up the green seedlings that do not change color, and I am deeply distressed! Is there any way to predict in advance and detect the disease as soon as possible? According to my practical observation for many years, there is a way, as long as you observe carefully, it is not difficult to find! Of course, there should be more than 2 pots of orchid pots for comparison. When it is found that the basin noodles are not dry for three days, while the other basin mouths are dry and white, it is a sign of soft rot and stem rot. At this time, Langen no longer has the function of breathing and absorption, but there is a water stain "reverse osmosis" phenomenon, which is reflected in the fact that the basin surface is wet and dry. Smell with your nose, there is a strange smell (similar to moldy smell)! At this time, it is necessary to promptly and decisively pull out the basin plant material for inspection, the conservative treatment is: pull out the plant material to expose the bulb and part of the root, let it dry by the wind, do not water it within 3 days, dry and then irrigate the root with chloramphenicol and carbendazim twice. Chloramphenicol eyedrops can also be used to drip the infected corm. If necessary, pour the pot and check. After removing the rotten roots, soak in potassium permanganate 1pm 1000 solution for more than 1 hour. Cool and dry thoroughly after using clean plant material on the basin, shade for more than a week, during the period still need to buckle water, with dry maintenance. This is the best policy.
