1. Potassium permanganate treatment. Soak the planting material with a concentration of one thousandth for more than 10 minutes. Potassium permanganate is a strong oxidant, and its purple liquid is too concentrated to burn the orchid plant, so it should be used with caution.
2. Methyl tropium (methyl tobuzin) or carbendazim treatment. It is also soaked in planting material with a concentration of one thousandth for more than 10 minutes. Both are broad-spectrum fungicides, which are often used in soil disinfection in agricultural production and have good results. This concentration of liquid medicine can also disinfect and prevent diseases of orchid plants.
3. Steaming in a pressure cooker. Add an appropriate amount of water to the planting material and put it directly in the pressure cooker like cooking rice, and wait for 10 minutes after the heat rises. All germ eggs can be killed 100%.
4. Stir-fry in an iron pan. The principle is the same as 3. But first remove the "sludge" from the pot.
5. Microwave oven treatment. Put the planting material in the stainless steel liner of the waste pressure cooker (see the last picture), and then put it in the microwave oven for 3---5 minutes, and the effect is also good.
6. Sun exposure, the cheapest, affordable and effective method. The "waste" planting material accumulated by depotting is exposed to the sun on the cement floor for more than 3 days on the "dog days" of summer heat. Exposure to sunlight has two functions, one is the use of strong ultraviolet light sterilization; The second is to use scorching high temperature sterilization.
According to the measurement, when the daily maximum temperature is 35 °C, the cement floor can reach more than 60 °C at 2 p.m. The maximum temperature of coagulation and denaturation of biological proteins is 45 °C, so it can be sterilized. In fact, the natural environment deep in the mountains orchids can grow well without artificial pesticides, in addition to the environment ventilation and suitable climate, the sun shines is an irreplaceable factor.
Note: Take advantage of the sun exposure to the planting material, it is best to check the weather forecast in advance, choose a sunny day of 35°C for more than three consecutive days, and move out of the stall in the cool morning. After sunset in the afternoon or before sunrise the next day, be sure to sieve to remove the dust that affects Langan's breathing.

Hello, we generally don't need sterilization, if you want to sterilize, you can spray it on the page with light lime water.
-
Sterilization can use carbendazim, methyl tobuzin, chlorothalonil.
1. Anthrax.
It is held all year round, and the hot and rainy season is even more rampant. In addition to improving the environment, the prevention and control methods are improved.
2. Scale insects.
In the case of high temperature and humidity and poor air flow, the reproduction is the fastest. Use conventional methods to prevent and control.
-
Drugs such as scale-dead, carbendazim or chlorothalonil.
During the growth period, orchids are susceptible to scale insects, which are relatively easy to handle. During the maintenance period, the insect leaves need to be pruned in time, and after pruning, the orchid can be sprayed with pepper water or pepper water, etc. If the number of scale insects is large, you can also spray the orchid with pesticides such as scale-dead, carbendazim or chlorothalonil.
During the growing season, orchids can also be attacked by spider mites, which can endanger the young leaves of orchids. If the orchid is infested by red spiders, after cutting off the leaves, you can spray it with mite removal, mite-sweeping, grasshopper forest or dimethoate. The agent 7 10 days can be sprayed on the orchid 1 time, and it needs to be sprayed 3 or 4 times in a row.

What medicine is good for orchid sterilization, and introduce you to this most effective bactericidal drug.

Potassium permanganate or carbendazim are generally used for disinfection of orchids.
Chlorothalonil or methyl tobuzine can also be used.
Dilute the disinfectant solution with water first to ensure that the content is about 1/1000. If you want to disinfect the foliage, you need to put the disinfectant in a watering can and spray it on the leaves. If the roots are disinfected, the plants need to be removed from the pot, the old roots and rotten roots should be cut off, and then soaked in disinfectant solution, dried and replanted.
If the planting material is disinfected, in addition to soaking the disinfectant, it can also be exposed to sunlight.
1. What kind of medicine to use.
Orchids are usually disinfected with carbendazim or potassium permanganate, which are also more common disinfectants. The carbendazim solution can be sprayed on the foliage and can also be soaked in the roots. Potassium permanganate solution.
It is mainly used to disinfect the roots. In addition, methyl tobuzin and chlorothalonil also have disinfection effects.
Second, the disinfection process.
1. Dilution with water: Whether it is carbendazim or potassium permanganate, enough water is needed to use it. The content of carbendazim solution should be controlled at about one thousandth, and potassium permanganate solution should be diluted to pink before it can be used. The concentration is too high.
Cause damage to the plant.
2. Foliar disinfection: Foliar disinfection usually uses carbendazim solution. It is usually used for diseased plants, after the diseased leaves are removed, the diluted disinfectant is put into a watering can and sprayed on the foliage.
3. Root disinfection: Root disinfection can use carbendazim or potassium permanganate. Carefully remove the plant from the pot and remove some of the old soil to expose its roots.
After that, the old and rotten roots are cut off and soaked in disinfectant. This method is usually carried out when the roots are rotten or repotted, and after disinfection, it should be dried and replanted to avoid the disinfectant residue in the soil.

1. High temperature disinfection method:
Put the planting material in the pot and cook, or put it in a plastic bag, and heat it in the microwave for 5 minutes to kill germs and eggs.
This method is cumbersome and is only suitable for disinfection when the amount of planting material is small.
2. Scorching sun exposure method:
Spread the planting material evenly on a clean ground or wooden board, accept sun exposure, and often turn the planting material to make it fully exposed to the sun, about 5-7 days, you can kill most of the germs and insect eggs.
Although this method is not as thorough as the previous one, it is simple and convenient, and it is more commonly used.
3. Potassium permanganate disinfection method:
Put the planting material in a large plastic bucket, water it thoroughly with potassium permanganate 500 times, then cover the lid, rinse it with water two days later, and then use it to grow orchids. Sails are sold.
4. Fungicide irrigation method:
The orchid planting material was watered thoroughly with the dilution of the soil disinfection fungicide sodium disulfon, sealed for 24 hours and then dried in the sun.

Disinfection of planting material depends on what material you use, if it is cinder or pond mud, then use fire, volcanic pebbles are washed away, humus soil bark or something to ferment.

A solution of potassium permanganate will do.
1.The planting material for raising orchids must be loose and love, because the roots of orchids also need to breathe, and its root system is also fleshy roots, and it does not like too much water, so the better planting materials are volcanic stones, broken bark, etc. >>>More
