How to prevent orchid viral diseases? Introduction to practical methods

To date, there is still no specific drug that can completely cure viral diseases, nor is there a good method that can avoid harming the orchid plants while achieving a relatively good therapeutic effect. This is simply because there is no drug or method that can distinguish the virus inside the cell from the cell's own proteins, kill the virus, and yet not damage the cell's own proteins. Therefore, fororchidsthe prevention and control of viral diseases is mainly based on prevention, as well as improvingcultivationconditions, so that they grow vigorously and increase their resistance. 1. Strictly select disease-free plants forcultivation. 2. Control and eliminate virus-transmitting insects. In combination with spraying fungal drugs once a week, add systemic drugs such as dimethoate and methomyl, etc., to eliminate insects with piercing-sucking mouthparts. 3. Improvecultivationconditions, mainly by doing a good job of cooling and ventilation, increasing humidity, and applying fertilizer reasonably. 4. Prevent artificial mechanical transmission. Becauseorchidviral diseases have a latent symptom phenomenon, disinfection work should be done well for pruning and other tools that come into contact with the plants. Before and after cutting each plant, the scissors must be heated over fire before use. 5. Cut off the source of infection. Once a diseased plant is found, it must be isolated or burned. 6. During cultivation, try to avoid artificially causing damage to the orchid plants, so as to prevent the disease from invading through wounds. Liu Zhongjian
