What medicine is used to disinfect orchids

1. What medicine to use

Carbendazim or potassium permanganate are usually used to disinfect orchids, both of which are also relatively common disinfectants. The carbendazim solution can be sprayed on the leaves or soaked on the roots. Potassium permanganate solution is mainly used to disinfect the roots. In addition, thiophanate-methyl and benomyl also have disinfecting effects.

2. Disinfection process

1. Dilute with water: Whether it is carbendazim or potassium permanganate, sufficient water is needed for use. The content of carbendazim solution should be controlled at about one thousandth, and the potassium permanganate solution should be diluted to pink before use. Too high a concentration can harm the plants.

2. Foliar disinfection: Carbendazim solution is usually used for foliar disinfection. It is usually used on diseased plants. After removing the diseased leaves, put the diluted disinfectant into a spray bottle and spray it on the leaves.

3. Root disinfection: Root disinfection can be done with carbendazim or potassium permanganate. Carefully remove the plant from the pot and remove some of the old soil to expose its roots. Then cut off the old and rotten roots and soak them in disinfectant. This method is usually used when the roots rot or when repotting. After disinfection, the plants should be dried before replanting to avoid disinfectant remaining in the soil.

4. Disinfection of planting material: Planting material is the matrix needed to grow orchids, which is often plant fiber with high air permeability. Generally, disinfection can be done by exposure to the sun or by soaking in potassium permanganate and carbendazim.
