Dishui Guanyin, with bright green leaves, is a kind of home plant that likes sunshine. As a person who loves flowers, I believe we all know how to cultivate Dishui Guanyin. However, in the process of breeding, it is inevitable that diseases and insect pests will be caused by improper cultivation or careless maintenance. what about the Guanyin worms in dripping water? First of all, flower friends need to calm down, then find the cause, and finally solve the problem, and this requires us to learn about the pest control of dripping Guanyin.

First, dripping water Guanyin long worm how to do

As a common ornamental plant, Dishui Guanyin is tall and beautiful. However, their large body size is also more affected by insect pests. Many flower friends will find that if they do not see Guanyin for a few days, they will be sick, and the leaves are full of rotten holes, and sometimes they will see small worms. This shows that there are insect pests. What about Guanyin worms in dripping water? The following are several kinds of diseases and insect pests of dripping Guanyin and their control methods. Flower friends should keep in mind!

Disease and insect pest control of Dishui Guanyin

1. Reaction on leaves, leaf spot and anthracnose

Different parts of the symptoms, the corresponding disease is different. It is understood that if it is reflected on the leaves, then dripping Guanyin generally has two kinds of diseases and insect pests: one is leaf spot, and the other is anthracnose.

① leaf spot

Leaf spot disease, as the name implies, there will be spots on the leaves of dripping Guanyin, which suffers from the disease.

Solution: foliar spray with chlorothalonil or carbendazim 800 times, 2-3 times in a row, every 7 days.

② anthracnose

After suffering from this disease, dripping Guanyin leaves will produce small black or black-brown round spots, which will soon expand and connect into pieces. 2 the whole leaf will turn black and rot in 3 days, and a large number of orange-red sticky particles will be produced on the spot, that is, conidia and conidia.

Solution: anthracnose should be foliar sprayed with 75% methyl topiramate 500 times, once every 7 days, 2-3 times in a row, basically controllable. Because Guanyin is a foliage plant, once the leaves get sick, it will inevitably affect its ornamental effect, so we should give priority to prevention.

2. Reaction on the stem, Fusarium wilt

Reaction on the stem, there is a Fusarium wilt, caused by bacterial infection, this disease is not easy to detect at first, once found, it will be very serious. If it is found that the stem is crooked to one side, or there is wilting, it must be Fusarium wilt.

Solution: the disease can be removed with a knife, and the boundary between the disease and the non-disease is very clear, and it can be broken off by hand. If the diseased area is less than 1/3 of the stem, you can apply a layer of chlorothalonil solution to the non-diseased area and keep it dry. Apply it again every 10 days, and you can basically recover after 20 days.

4. Reaction on the back of leaves, red spider

The most serious diseases and insect pests in Dishui Guanyin are mites, commonly known as red spiders. Red spiders are generally born on the back of leaves. They not only absorb the nutrients of leaves, but also spread various viruses. It greatly affects the growth of plants, so you must check it frequently and treat it immediately once it is found.

Solution: it is worth mentioning that the reproductive ability of red spiders is very strong, five days in summer can reproduce a generation, less than ten days, a plant is basically red spiders. Therefore, the harm of red spiders can not be ignored. In order to protect dripping Guanyin to grow normally, it is necessary to eliminate red spiders. In addition to spraying special pesticides, another way is to spray washing powder with water.

① spraying pesticides, prevention and control of red spiders, usually should pay attention to observation, found that the leaf color is abnormal, should carefully check the back of the leaves, individual leaves injured, can remove insect leaves; more leaves occur, should be sprayed as early as possible, the commonly used pesticides are propargite, triclofenac, dimethoate, Huachongjing, quick killing, and so on.

② washing powder sprayed with water, washing powder is a daily necessities, the main ingredient is sodium alkylbenzene sulfonate. Sodium alkylbenzene sulfonate in washing powder enters the body through the respiration of pests, causing them to die of poisoning. The 400-fold solution was sprayed on the back of leaves and twigs. After 1-2 days, the death rate of pests such as aphids, whitefly, red spiders, inchworms and diamondback moths reached 100%.

5. Rotten root

That is, the root of dripping Guanyin is completely rotten. This is mainly caused by dripping Guanyin basin soil is too wet, it is easy to cause dripping Guanyin root rot phenomenon.

Solution: dripping Guanyin rotten roots how to do, first keep the bottle clean, combined with water or nutrient solution, and then wash the tuber and root mucus, cut off the rotten roots.

6. What is the disease of dripping Guanyin giving birth to white hair

Some flower friends bought a pot of dripping Guanyin on a treasure in early February, but unexpectedly, it has been five or six days since I bought it. What if I found white hair when I got up this morning?

Solution: cut off the rotten parts with a knife, apply carbendazim or dry them. There is no need to put on the basin this season, throw it in a dry place, and put on the basin again at the beginning of spring. If you have to serve it, don't water it.

Matters needing attention in dripping Guanyin Culture what if the leaves of dripping Guanyin turn yellow?

Under the condition of warm and humid air and sufficient soil moisture, water will drip down from the tip or edge of the leaf, and the flowers bloom like Guanyin, so it is called dripping Guanyin. Now there are also a lot of people breeding Dishui Guanyin, but what if the leaves of Dishui Guanyin turn yellow? what do we need to pay attention to during the breeding process? The following is to introduce the matters needing attention in Dishui Guanyin culture, as well as the treatment of the yellowing of Dishui Guanyin leaves.

Matters needing attention in Dishui Guanyin Culture

As a result of dripping Guanyin stem tissue is relatively loose, such as poor water quality is easy to be polluted and cause rotten roots and stems rot. Therefore, to keep the bottle water clean, we should also wash the mucus on the tubers and roots and cut off the rotten roots in combination with changing water or back culture solution.

Dishui Guanyin is a very common domestic green potted plant, but because it is a tropical plant, it generally does not blossom in the north. But if the temperature at home and other conditions are suitable, it will also blossom.

It does not have high requirements for soil, but it grows best in sandy loam or humus loam with good drainage and organic matter. As Dishui Guanyin naturally likes a warm, humid and semi-overcast environment, it is not cold-resistant, so it is necessary to keep the basin soil moist during the growing season.

In summer, the flowerpot should be placed in a semi-overcast ventilated place, and water should often be sprayed around and on the leaves to increase air humidity, reduce the leaf temperature and keep the leaves clean.

Because dripping Guanyin grows very fast, it likes fertilizer. Nitrogen, phosphorus and potassium compound fertilizer is applied once or twice a month (in which the proportion of nitrogen can be appropriately higher). If a little ferrous sulfate can be applied, the leaves will be bigger and greener. Long-term lack of fertilizer is easy to cause the lower end of the stem of dripping Guanyin empty, affecting the ornamental value. When the temperature drops into the dormant period, it can be reduced or not fertilized.

If you want Dishui Guanyin to be small and exquisite indoors, just wait until its seedlings grow to about a foot, suitable for family display, and immediately spray the whole plant with 2% paclobutrazol solution, and then the stems and leaves are no more than 40 centimeters high. and the leaves are thick, the ornamental value is very high. Spraying once in half a year or so can play a good role in controlling height. The juice in dripping Guanyin leaves has itched the skin after human contact, so be careful when you touch it.

Temperature: Dishui Guanyin can only grow well in an environment of no less than 18 ℃. If the temperature is lower than 18 ℃, Dishui Guanyin will be dormant and stop growing. Special attention should be paid to indoor ornamental cultivation.

Fertilization: dripping Guanyin likes fertilizer, we should fertilize dripping Guanyin every month.

Watering: dripping Guanyin should be watered more in summer, but not too much, dry and wet when appropriate, and there can be no stagnant water in the soil, otherwise the tubers will rot. Dormancy in winter, less watering, stop fertilizing.

Sunshine: dripping Guanyin likes yin, don't let the sun shine directly. Let Dishui Guanyin become wilted, mainly because there is not enough fertilizer, we should pay attention to topdressing.

Winter maintenance

Dishui Guanyin likes a warm, humid and slightly shaded environment, but the flowering period should be sunny, otherwise the Buddha flame will be green and affect the quality. It is necessary to ensure that the light lasts for 5 hours every day, otherwise the petiole will lengthen and affect the ornamental value. Dishui Guanyin is not cold-resistant and will be moved into the greenhouse in mid-October. In summer, under the condition of shade, we often spray water to cool and moisturize.

Dripping Guanyin likes moist and fertile soil, which is often called "big fat and big water". It should be watered during the growth period. Topdressing can be applied alternately with liquid fertilizer such as rotten bean cake water and chemical fertilizer (compound fertilizer or diammonium phosphate), once every 2 weeks. When topdressing liquid fertilizer, do not pour fertilizer and water into the leaf sheath to avoid decay. The use of ferrous sulfate in potted dripping Guanyin, the application of ferrous sulfate can make the leaves bigger, thicker, green, smooth and shiny, and the petiole is not easy to elongate, so as to ensure the beauty of the leaves. At the same time, it can promote the formation of buds and prolong the florescence. The specific method is to dilute ferrous sulfate into a 2% solution and pour it once every one month, each time thoroughly.

Pest control measures

There are generally two kinds of diseases of dripping Guanyin on leaves, one is leaf spot, the other is anthracnose. Leaf spot disease can be sprayed with chlorothalonil or carbendazim 800 times for 2-3 times in a row, each time every 7 days. Anthracnose needs to be sprayed on the leaf with 75% methyl topiramate 500 times.

Fog, once every 7 days, 2-3 times in a row, is basically controllable. Because Dishui Guanyin is an ornamental plant, once the leaves get sick, it will inevitably affect its ornamental effect, so we should give priority to prevention.

Reaction on the stem, there is a Fusarium wilt, caused by bacterial infection, this disease is not easy to detect at first, once found, it will be very serious. If it is found that the stem is crooked to one side, or there is wilting, it must have given birth to Fusarium wilt, and the disease can be removed with a knife. The boundary between the disease and the non-disease is very clear, and it can be broken off by hand. If the diseased area is less than 1/3 of the stem, you can apply a layer of chlorothalonil solution to the non-diseased area and keep it dry. Apply it again every 10 days, and you can basically recover after 20 days.

The most serious pest in Dishui Guanyin is the mite, commonly known as the red spider. Red spiders are generally born on the back of leaves, it not only absorbs the nutrition of leaves, but also spreads various viruses, seriously affecting the growth of plants, so it must be checked frequently and treated immediately once found. It can be treated with mifengqing, Saomijing, imidacloprid and other drugs.

What if the leaves of Guanyin turn yellow?

1. Lighting problem

Dripping Guanyin needs to grow in a cool and bright environment. If you don't get enough light for a long time, the leaves of dripping Guanyin will lack chlorophyll. As time goes on, the leaves will turn yellow. Therefore, to pay attention to the lighting problem, you can put it in a light-ventilated place.

2. Too little watering

Dripping Guanyin is more addicted to water, and if it is not watered for a long time, the leaves will turn yellow because of drought. Therefore, always keep the soil moist, pay attention to watering thoroughly, not just wet the surface of the soil.

3. Lack of nutrients

If the soil is too barren and lack of nutrition, it will also cause the leaves to turn yellow. therefore, it is necessary to add nutrition to the soil in time and apply some nitrogen, phosphorus and organic fertilizer.

4. The temperature is too low

Dishui Guanyin is more suitable for warm and humid climate. due to the low temperature in winter and being out for a long time, it is easy to frostbite leaves and turn yellow. At this time, it should be placed in an indoor place with constant temperature and plenty of light.

5. Insect pests

Dripping Guanyin is also easy to cause worms to appear, especially when red spiders are concentrated on the leaves, which will cause the leaves to lose nutrients and turn yellow, so you can spray potions to prevent and cure them.
