Do orchids need to be flushed after using fungicides

After the use of fungicides for orchids, they usually do not need to be specially flushed.

Because the bactericidal drug is generally no longer effective after about 7-10 days after application, then the flush may reduce the efficacy of the drug and cannot effectively prevent germs.

If a serious disease occurs in the orchid, it is recommended to take the following steps:

1.Cleanup: Remove infected leaves and tissues and dispose of them properly.

2.Ventilation: Strengthen the ventilation of the orchid environment and avoid humid and closed environments.

3.Light: Provide proper sunlight but avoid sun exposure.

4.Sterilization: Use appropriate fungicides for prevention and control, such as carbendazim, methyl tobuzin, etc.

It should be noted that bactericidal drugs are only one of the means of prevention and prevention, and good maintenance management is equally important for the prevention of diseases. Providing the right growing environment, such as temperature, humidity, light, and moisture management, can help improve the disease resistance of orchids and reduce the occurrence of diseases.

It is best not to rush to use water for orchids after medication, mainly for the following reasons:

1. Rinse the leaves, which will reduce the efficacy of the medicine, and if you water it, it will be equivalent to sprinkling the medicine in vain.

2. Watering at this time may cause soil compaction, and watering is the most appropriate after about three days.

3. At this time, the stomata of the leaves are closed, and watering will make the temperature of the leaves too high, which is not conducive to the growth of plants.

It is best not to rush to rinse the leaves of orchids with water after medication, which will reduce the efficacy

When repotting orchids, do orchids need to be sterilized?

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.

OK. Orchids can be disinfected with alcohol before potting, but be sure to choose a slightly higher concentration. For example, 75% alcohol is a good choice.

Of course not, alcohol still has a certain corrosiveness, if it is after the elimination of milk poison, it is not conducive to the growth of orchids, and may be inhibited, causing orchids to wilt.

Personally, I think it can be disinfected with alcohol, but don't choose a high and high concentration, appropriate alcohol is fine, and it volatilizes relatively quickly.

Can be disinfected with alcohol. It is better to use 75% alcohol, which will be more effective.

1. The orchid basin is soaked with clean water and detoxified, which can be disinfected with disinfectant water or by heating.

2. Prepare planting materials and other supplies. If you use fairy soil and planting stone as planting materials, you should soak the planting materials in water a week in advance. For example, orchid mud is used as planting material, which is dried under the scorching sun to kill insects and disinfect.

3. Disinfect orchid plants. Soak the pruned orchid plants in a solution of 1:1000 of tobuzin and potassium dihydrogen phosphate for an hour, and then cool until the roots are soft.

Suggestion: Healthy plants can grow well without disinfection, disinfection will harm the bluegrass, not conducive to growth, but if there is a wound, the wound should be dried in the pot.

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

What is the purpose of sterilization, if you divide the plant, treat the wound, and plant it without dividing the plant.

Methyl tobuzin or carbendazim! Carbendazim 10 grams 1 yuan.

I'm afraid I don't need to be so particular...

We will spray the orchids with some fungicide regularly, which will avoid some pests and diseases. Then, the fungicides we usually use are potassium permanganate, carbendazim, mancozeb and other fungicides. If we use a bad concentration of fungicide, especially potassium permanganate, its concentration is very high.

If you don't grasp it well, this orchid will have some anthrax problems, that is, black spots will appear on this leaf, so this disease is leaf spot. When we use fungicides, if we don't grasp the concentration, it will backfire, because some flower lovers often use fungicides that dilute Jianxiao, so the concentration will kill the orchids in the orchid. So, how do we use fungicides on it, it will not cause the phenomenon of drug damage, in fact, is very simple.

I'm going to share it with you today. In fact, the disinfectant we use for it can use this mancozeb. It is a broad-spectrum disinfectant and belongs to the systemic type.

Once 1000 ml of water is ready, the water that we dilute with this small spoon will not be too strong. Just right. In this case, it will have a bactericidal effect and will not cause pesticide damage.

If we need to dilute water when using carbendazim, we can also apply thifluzamide, a small powdered medicine. It is a systemic medication, that is, granules, and the method of use is very simple. We only use this small spoon to sprinkle it spoonful by spoonful, so that its concentration is not too high and affects the growth of the orchid.

It will be good to spray on the back, even the front, or even the surface of the potting soil.

As I shared with you before, when we care for orchids, we do this kind of neutering for them at least once a month. The sterilization work is mainly to play a preventive role. Then some commonly used fungicides are mancozeb or carbendazim.

But it should be noted here that you can't blindly use the same medicine. These two drugs are best used alternately. If a drug is used for a long time, it can develop resistance.

So when we use these drugs, we recommend that you use this spraying method, which is to spray the leaves of your orchid plant and the surface of the potting soil, which will have a very good preventive effect. But after using this method, if we spray these fungicides on the surface of the pot, it will slowly penetrate into the potting soil and kill some of the rhizopus and some beneficial bacteria in the potting soil, so this is not conducive to the growth of orchid plants. If these fertilizers are not supplemented in time at this time, it will take a long time to resume their growth in the later stage, so it is very important to supplement these fertilizers.

When do I need to replenish? 1.When the fertilizer is replenished, we can use these fungicides for about 8 to 12 hours.

These drugs have basically been absorbed by the plant, and then the evaporation is almost gone, and the effect has passed. So let's supplement it with this fungus fertilizer. In this case, it will have a very good effect.

2.Fertilizer selection. There are two types of fertilizers that I usually use.

One is this granular microbial organic fertilizer. This microbial organic fertilizer is relatively simple to use. Sprinkle a small spoonful in the potting soil about every twenty days, and the other is this em original dew.

This EM original dew, its pasta here has a large number of microorganisms and beneficial live bacteria, which can effectively promote the reproduction of Rhizopus, so that it can quickly recover growth, but also enhance the resistance of stool plants, as well as the cavity effect of promoting roots. Dilute it with water at a ratio of one to five hundred each time, give your orchid roots every seven to ten days, especially after using this fungicide, if we replenish it one more time, then the orchid will soon return to normal growth. Usually people give you orchids, and you must pay attention when you spray some fungicides to prevent them.

In the later stage, you must supplement them with this bacterial fertilizer in time, so that the orchid plants can resume growth as soon as possible.
