1、 With what medicine

To disinfect orchids, carbendazim or potassium permanganate are usually used, which are also more common disinfection drugs. Carbendazim solution can be sprayed on the leaf surface or soaked in the root. Potassium permanganate solution is mainly used to disinfect roots. In addition, tolbutrazine methyl and chlorothalonil also have disinfection effects

2、 Disinfection process

1. Dilution with water: both Carbendazim and potassium permanganate need enough water to use. The content of carbendazim solution should be controlled at about one thousandth, and potassium permanganate solution should be diluted to pink before use. Too high concentration will cause damage to the plant

2. Leaf disinfection: carbendazim solution is usually used for leaf disinfection. It is usually used for diseased plants. After the diseased leaves are removed, put the diluted disinfectant into the watering can and spray it on the leaf surface

3. Root disinfection: carbendazim or potassium permanganate can be used for root disinfection. Carefully remove the plant from the pot, remove some of the old soil and expose its roots. Then cut off the old and rotten roots and soak them in disinfectant. This method is usually carried out when rotten roots or pots are changed. After disinfection, it should be dried and replanted to avoid the residual disinfectant in the soil

4. Plant material disinfection: plant material is the matrix required for planting orchids, which is often plant fiber with high permeability. Generally, it can be disinfected by exposure, or soaked in potassium permanganate and carbendazim
