is a maggot. These small insects occur in the case of animal fertilizer application and wet potting soil, with the most abundant in spring. You've poured it with yogurt, and it's the spring season when small bugs are most likely to multiply. This small insect will turn into a small flying insect in a few days, and it should be killed as soon as possible.
In addition to soaking a few cigarette butts in water for a day and then trying to water them, there are two ways to do this:
1 Carbofuran Insecticide Carbofuran is a broad-spectrum insecticide that is effective against insects in the soil and leaves. Flower markets have small packages dedicated to home purchases, and the usage and dosage can be seen in the packaging.
2 Household insecticides Try with household insecticides, which are generally effective. It is also the most commonly used method and has quick results.

If it is a white bug, it should most likely be a scale worm.
Prevention should be the main focus on scale insects. It is necessary to always pay attention to the inspection of the plant, find insect pests, and eliminate them as soon as possible to prevent the spread.
When the disease of Junzi Orchid occurs, it can be treated with artificial and drug treatment. If only 1 or 2 leaf tips are found to be infestation, they can be scraped by hand, sharpened with thin wooden strips or removed with bamboo skewers.
If a large number of insects appear, they can be sprayed with 2-imidothion emulsion solution, or dimethoate emulsion, which can be killed by spraying 1 or 2 times.
Extended information: The body wall surface of the scale insect may be hardened with 1 layer of hard shell, or have powdery waxy secretions (or body wax secretions are white powdery, glassy, or tan shell-like, and therefore secrete waxy shells, and females have no eyes, no feet, and no antennae. Males have well-developed feet, antennae and wings, and are parthenogenetic or hermaphroditic, and some species are important pests.
Common shapes are round, oval, linear, or oyster-shaped. The larvae have short legs, and the young can move to feed, and the longer legs are degraded and sedentary. The common ones are red scale, brown scale, Kang scale, sagittal scale and blow scale scale and so on.
In addition, the secretion of scale insects can also cause soot disease.
The female adults of scale insects are all wingless, and the division of the head, thorax, and abdomen is not obvious, and the appearance appears to be similar to that of nymphs, some of which are only larger, while others have distinctly different body colors.

It is estimated that it should be a flea fly.
Larvae, due to the fact that the pots often pour tea leaves, wash rice water.
Milk, buckle egg shells and other substances, which cause fermentation, are just right for small flies.
Flea flies, mushroom flies, etc. reproduce and grow, and a spray can only kill a part of the adults, and the eggs in the soil will hatch, so it is always in a steady stream, and it is difficult to break the roots. So, it's best to start with the breeding base.
1. Irrigate the potting soil with 1 1500 dimethoate water, and kill it all once or twice. The dimethoate flower shop sells a small bottle for 2 yuan, which is not used up. This pesticide works very well, but the taste is relatively large, it is best to use it outdoors, and it will be tasteless after two or three days, citrus peel liquid:
Take 50 grams of citrus peel, add 500 grams of water and soak for 24 hours, filter and pour the filtrate into the soil.
Pepper liquid: Take 50 grams of chili pepper and add 10 times water to boil for 20 minutes, then filter and put to room temperature, and pour into the soil.
2. Homemade insecticides:
Mash the garlic and sprinkle it in the potting soil to kill the earthworms.
Soil pests such as ants and nematodes.
Citrus peel liquid: take 50 grams of citrus peel, add 500 grams of water and soak for 24 hours, filter and pour the filtrate into the soil.
Pepper liquid: Take 50 grams of chili pepper and add 10 times water to boil for 20 minutes, then filter and put to room temperature, and pour into the soil.
Hygienic balls. After grinding the sanitary ball, it is sprinkled in the potting soil to loosen the soil, which can control pests in the soil.
of sundries.

1. How to get rid of small white worms that wriggle in flower pots.
If you see a wriggling white worm in the pot, you should first take out all the plants in it and move it to another pot, remember not to hurt the roots, it is necessary to save the plants first. Next, you can boil the water, and when it boils, you can pour it into the soil, so that the little white worms can be scalded to death, and the effect is quite good. The water in the pot can be slowly filtered through the holes at the bottom, and then put it in the sun to dry, and finally this kind of soil can still be used, and there should be no worry about small white worms, and the previous small white worms are in the soil, which can also be said to be a good fertilizer.
Second, there is a wriggling white worm in the flower pot to eliminate the method.
If you see small white insects in the flower pot, you can first put the cigarette butt in the soil, which has a good effect on many small insects. Or you can get some tobacco out, and then put it in a water cup to soak, about half an hour or so to pour the water into the pot, if the water is not a lot, you can also get a few more glasses, remember not too much. Or you can roast the soil over the fire, but you should take out the plants before you get them, so as not to kill them.
In fact, it is not very difficult to eliminate the wriggling white worms in the flower pot, only the reasonable use of the method is enough. In addition to the above, you can also prepare some laundry detergent to dilute it in water, and then pour it into the flower pot, which can also kill the small white worms.
This kind of white insect is a scale insect, this kind of insect pest can harm the leaves, branches, fruits, etc. of plants, can lead to leaf yellowing and death, branches are dry, fruits are eroded, etc., the harm is very large, this insect pest can be said to be the most common in flower maintenance, the most easily induced insect pest.
Potted flowers at home are susceptible to scale insects, which is mainly due to the long-term humidity of the soil, coupled with poor indoor ventilation conditions, indoor maintenance after all can not be compared to the outdoor breeze extending in all directions, strong wind can make the soil moisture volatilize quickly, but also take away a lot of harmful substances, but the environment of home maintenance is not the same, usually many flower friends maintain their flowers indoors, or close the balcony, and do not often open the window for ventilation, which leads to the production of scale insects.

If there is a small white bug in the potting soil, most of them are mealybugs, and if there is a mealybug in the soil, it is a kind of scale scale worm. However, there are no scales on the insect body, and if there is a mealybug in the soil, it will be covered with white cotton around the roots of the plant.
As a harmful insect in the soil, mealybugs can be prevented by changing the potting soil regularly, such as changing the potting soil 1-2 times a year. In addition, you can also water the flowers with onion water every half a month to prevent the occurrence of pests and diseases in the soil.

1. Kill them with lime or spray mosquito repellent.
2. Take 2 grams of laundry detergent, add 500 grams of water and stir into a solution, add a drop of clear oil, and spray the insects on the plants.
3. 50 grams of Sichuan pepper, add about 500 grams of water, heat and boil in a pot, boil into 250 grams of liquid medicine and spray.
4. After the mosquito coil is lit, hang it on the insect-containing plants, cover the plants and flower pots with plastic bags, and the pests will be eliminated after 1 hour.

The leaves of the junzi orchid are relatively sticky, and they are generally infested by scale insects, so it is best to use drugs to spray as much as possible, and you can use phosphorus and chlorpyrifos. You can also use your own insecticide, use 300-500 times the laundry detergent water, and gently wipe it with a soft cloth. It is best not to let the water of the laundry detergent run to the base of the leaves, it is best to use it every other day, and then wipe it with a clean soft cloth.
In the cultivation methods and precautions of Junzi Orchid, we must first prepare suitable soil for it, choose deep pots to plant, master the correct watering method, and pay attention to thin fertilizer and frequent application, so as to give Junzi Orchid sufficient nutrition. In addition, the pot should be rotated frequently during maintenance, and the plant can be planted by dividing the soil when changing the soil, and it can be well maintained by avoiding direct sunlight in summer.
1. Soil preparation.
It is best to use the soil containing humus to cultivate the Junzi orchid, and it is required to have good air permeability, good drainage and water retention, and the family can choose humus: muck soil: pastoral soil ratio of 2:
1:1 ratio. Be careful not to use humus completely, as the water evaporates too quickly, although it is breathable.
2. Choose a deep basin.
When maintaining the Junzi orchid, there is no need for a large flower pot, as long as its depth is deep enough, the size of the flower pot is determined according to the specific plant size, it is best to choose a breathable mud pot, followed by a clay pot, and the worst is a porcelain pot.
3. Water properly.
Orchid likes a humid growing environment, so in the summer, when the temperature is high and the water evaporates quickly, it should be watered once a day in the morning and evening. In spring and autumn, it is watered every 3 or 4 days, once a week in winter, and more watering is required for outdoor maintenance.
4. Apply thin fertilizer frequently.
When maintaining the Junzi orchid, it is necessary to give it sufficient nutrients, and apply a well-rotted liquid fertilizer every half a month, such as rice washing water, etc., or soybeans, fish offal, etc. In the dormant period in summer, no fertilization is required, and some potassium dihydrogen phosphate with fertile leaves should be applied when the flower buds are grown.

It may be caused by scale insects.
Planting skills: 1: First of all, we must prepare suitable soil for it, choose deep pots to plant, and master the correct watering method.
2: It is also necessary to pay attention to the diligent application of thin fertilizer and give sufficient nutrition to Junzi Orchid. You can choose fertile leaf water-soluble fertilizer, which is safe and hormone-free.
3: In addition, the pot should be rotated frequently during maintenance, and the plant can be planted by dividing when changing the soil, and direct sunlight should be avoided in summer.

Hello answer, I have seen your question, and I am sorting out the answer, please wait a while This is caused by the harm of scale insects in your Junzi orchid, and it is best to spray special pesticides to prevent and control this situation, such as killing phosphorus, chlorpyrifos, etc. If the agent is not easy to buy, it is recommended to use an environmentally friendly method, soak the rag with 300 500 times the liquid laundry detergent solution and wipe the leaves, and put it in a well-ventilated and well-lit position. 2 After 3 days, wipe it again with a clean water rag to wipe off the residue of laundry detergent.
Question: What is the reason for the yellowing of the leaves of the gentleman's orchid?
Orchid is not tolerant of stagnant water, so wait for the soil to dry before watering. 3. Excessive fertilization: It is best to apply rotten fertilizer or diluted thin fertilizer to Junzi Orchid.
4. Soil compaction: The potting soil should be replaced every 1-2 years of cultivation.
-
This kind of thing is generally caused by bugs, which will block some foam. In this case, it is best to put it in a sunny place, which can be used to repel insects with ultraviolet light. It can also be sprayed directly with insect repellents.

The white sticky thing between the leaves and leaves of the junzi orchid should be a scale insect disease.
1.Scale insects are insects of the order Homoptera, the family Shield Scale, the female is wingless, and the feet and antennae are degenerated; The male has a pair of soft wings, well-developed feet and antennae, and stinging and sucking mouthparts. There are 6 common species, including Blowing Cotton Scale, Camphor Camphor Round Shield Scale, Bran Scale, Korean Ball Scale, Mulberry White Scale, and Kang's Mealybug.
2.Scale insects insert their stinging and sucking mouthparts into the leaf tissues of the orchid for life. It not only plunders a large amount of plant juice, destroys leaf tissue, and causes tissue fading and death; It also secretes some special substances to make local tissues deformed or form galls.
3.Spray once every 7-10 days, 2-3 times in a row. It can be sprayed with 40% dimethoate 1000 times, or 50% malathion 1500 times, or 255 imithion 1000 times, or 50% dichlorvos 1000 times, or deltamethrin 3000 times.

1. Changing soil and exposing to the sun.
There are insects in the soil of the orchid, which is generally the reason why the soil is not clean, and it can be changed in time to expose to the sun. Depot the orchid plants from the pot and remove the soil attached to the roots, taking care not to harm the root system. Prepare the new soil, spread it out in the hot sun, and dry the eggs and pests in the soil by exposure to the sun, and then replant it into the soil.
Second, hang sticky insect boards.
If the insects in the Monarch Orchid are small black flies, you can hang a sticky insect board next to the Monarch Orchid plant, so as to attract the little black flies to stick to the board, and the effect is relatively good.
3. Water oranges.
The orange peel is collected, then soaked in clean water, after soaking for a few days, the orange peel water is taken out and watered into the soil, the substances in the orange peel can kill the insects in the soil of the orchid. In addition, the orchid is very acidic, and soaking orange water can adjust the acidity and alkalinity of the soil, thereby providing a suitable growing environment.
Fourth, the tobacco is soaked in water.
Collect the tobacco, soak the tobacco in clean water, and then use it to water the Junzi orchid, the tobacco can also play a role in driving away insects and killing insects.
5. Spray pesticides.
Select the insecticide according to the type of insect, and then dilute it with water according to the instructions and spray it on the plant to avoid pesticide damage caused by excessive concentration.
2. How to deal with the rotten roots of Junzi Orchid?
1. Adjustment of water and fertilizer management.
You can't water too much of the orchid, and you should water it in moderation. Too much watering will make the nutrient soil too much water content, poor air permeability, the growth of roots can not get enough oxygen, resulting in rotten roots. When watering, you should also be careful not to pour water into the center of the orchid, so as not to cause water accumulation along the stem to the root.
Watering is usually done once every 2 weeks, accompanied by fertilization.
2. Treatment of potting soil.
The nutrient soil bought from the market has poor air permeability, and the soil is too raw or too ripe. If the soil contains components that are not completely decomposed, long-term watering and fertilization in the potting soil will produce heat and are easy to rot roots. Or the home-prepared flower soil is more clayy, has a large water content and is not easy to evaporate, and the air permeability is poor, and bacteria will invade the plant with the wound, resulting in root rot.
Therefore, the choice of soil is very important before planting. If the flower pot of the cultivated gentleman's orchid is poor, you can consider replacing it with a porcelain pot or a stoneware pot.
3. Treatment of rotten roots of Junzi Orchid.
Remove rotten roots: Plant the rotten roots of the orchid from the pot, gently peel off the soil, then rinse the roots with water, and use scissors to clean the rotten roots. If the leaves are yellow or weak, it is best to cut off the damaged leaves as well.
Disinfection treatment: Soak the cleaned roots in potassium permanganate solution for 5 minutes, and then dip a little sulfur powder or plant ash or carbendazim, and then dry in a cool place (about 2 days).
The petals are large and scattered, a pot of high-grade Junzi orchid can bloom 28-45 or even more flowers, the interval between the flowering of each flower is not more than 7 days, and the flowers are neatly round for the top grade. The flowers are not neat, and the flowers are not much, and the junzi orchid that blooms in batches is of medium grade. If the flowering period of the orchid is one or two months, and one or two flowers bloom, it is inferior. >>>More
Before potting, all these roots are pruned off to avoid unnecessary trouble in the later stage.
One is to pay attention when watering, the second is to often put it in a sunny place, the third is to use the bottom bracket to put it under the flower pot, and the fourth is not to choose too short when choosing a flower pot.
When changing pots, whether to replace all the original old soil with new nutrient soil, if the spring change, it is best not to replace all the old soil, at least leave a part of the soil on the root system, otherwise, it is easy to hurt the roots, easy to affect its subsequent growth and survival, because this soil is the heart of the soil, that is, the root system should leave a part of the original soil, and the other soil can be replaced with new nutrient soil. If you use nutrient soil to raise Junzi orchid, it is best to add a little garden soil to it, that is, ordinary soil and sand, or perlite vermiculite, so that if you match the soil, the nutrients are more comprehensive, and it is also relatively loose and breathable, and the drainage is good.
The reason for the yellow leaves of the Gentleman's Orchid is mainly due to improper management. There are several reasons for the yellow leaves of Junzi orchid: 1. The water is too big: >>>More
