White silk disease

The root and stem are often infected, and the diseased part is often waterlogged, sometimes accompanied by yellow fluid exudation. A white silk-like substance grows in the affected area, sometimes radiating. The sclerotia the size of rapeseed was produced on the hyphae, which was white at first and brown in the later stage, which finally led to the lodging and death of the plant. During the rainy season, the substrate should be prevented from getting too wet and ventilation should be paid attention to. The substrate should be disinfected before use, the sclerotia can be killed when the temperature reaches 100 ℃, and the silk is easy to die when exposed to the hot sun.

If you find diseased plants, isolate them immediately, destroy them immediately, clean up diseased plants, diseased leaves, cultivation substrates, etc., and block the source of infection. At the same time, the surrounding plants can be sprayed with Jinggangmycin 500 × 700 times, directly sprayed gonorrhea plants for 2 or 3 times, and can be completely removed. Jinggangmycin is one of the most effective drugs to control white silk disease at present. You can also use 15% pink rust rather than wettable powder mixed with fine dry soil to spread 200 parts on the rhizome of the diseased plant.

Stem rot

Damage to the base of the stem, the base of the stem turned brown at the initial stage, the leaves turned green, the leaf axis bent downward, the interior of the stem rotted like a sponge, and finally the whole plant died. It was found that the diseased plants were incinerated immediately, and the other plants were sprayed with 600 times of 27% copper noble suspension and 800 times of 50% thiophanate.

How to deal with the growing insects of the money tree, the prevention and control of diseases and insect pests / 4 diseases and 1 insect

As an excellent foliage plant, money tree not only has a beautiful shape, its unique and beautiful meaning, deeply loved by the majority of flower friends. However, because it is not maintained according to the cultivation method of the money tree, the money tree will also grow insects or get sick, thus seriously affecting the ornamental value of the plant, what about the money tree with worms? The following is the pest control of the money tree selected by the editor. Go in and have a look!

First, the money tree grows worms, spray with medicine

In the home money tree does not need to be outside, as long as careful maintenance, it is very difficult to be disturbed by diseases and insect pests. However, in a high humidity environment, the money tree will also grow worms and get sick, so what to do at this time? In fact, it is very simple, we just need to determine which kind of diseases and insect pests, and then spray them with medicine. The details are all in the prevention and control of diseases and insect pests of the money tree, let's move on.

Second, the prevention and control of diseases and insect pests, one insect and four diseases.

1. Scale insects

One of the most important pests of the tree, which occurs all the year round in the greenhouse, stabs into the leaves with mouthparts and sucks the sap from the leaves. Symptoms of damage: the leaves of the tree turn yellow, and the plant will die in severe cases.

Prevention and control methods: when there are few shell insects, you can gently wipe the diseased plant with alcohol to get rid of it; there are many diseases and insects, and when you see the shell insects climbing out from the mother, you should immediately spray: dichlorvos 1000-15000 times, 50% marathon emulsion 1000 times and so on.

2. White silk disease

The disease, also known as sclerotia root rot, harms the roots and stems of seedlings and young trees. Symptoms: money tree disease root stem cortex gradually become brown necrosis, severe cortical decay.

Prevention and control methods: the diseased plants were cleared in time; at the initial stage of the disease, 50g of 25% verapamil wettable powder was used to water the roots of the diseased plants with 50kg.

3. Brown spot

Another kind of disease and insect pest of money tree, it mainly harms leaves. Symptoms: the lower leaves began to get sick, gradually spread to the upper part, the initial stage was round or oval, purple-brown, the later stage was black, in severe cases, the sick class could be connected into pieces, so that the leaves withered and yellow fell off and affected flowering.

Prevention and treatment: after finding the above symptoms, you should immediately spray 50 carbendazim wettable powder 500 times, or 25% chlorothalonil 500 times, once every 7-10 days, 2-3 times will be effective.

4. Stem rot

As the name implies, it is a disease that harms the stem of money trees. It is generally spread by water splash, and moisture retention time is long and easy to occur. Symptoms of the disease: the stem or base of the tree rotts, causing the whole plant to die quickly.

Control methods: prevention and control measures of stem rot of money tree: at the initial stage of the disease, the noble suspension of 27% copper can be sprayed 600 times; when the disease is serious, some chemicals can be added during root irrigation or spray, such as: Ralstonia 50ml + carbendazim 15g.

5. Late blight

One of the main diseases of Artemisia mandshurica, it mostly occurs from July to August. Symptoms: the lower leaf tip of the money tree began to suffer from the disease, initially a dark green water-immersed anplastic disease spot, and turned brown after expansion. When the humidity is high, the head of the leaf back disease and health department is white mildew.

Prevention and treatment: remove the newly diseased leaves as soon as possible and burn them centrally so as to reduce the pathogen. The disease is mainly based on defense, before the onset of the disease, can be timely spraying 27% copper noble suspension 600 times liquid; the peak of the disease, spraying 72.2% Prike water agent 600 times 700 times liquid for prevention and treatment.

Artemisia angustifolia is a shade-tolerant foliage plant of Araceae, which was introduced from the Netherlands and is a popular indoor ornamental plant in recent years. Its leaves are short, round and string-shaped, like a string of coins, so it is named the money tree. With underground tubers, the plant spider grows from the latent buds on the tuber, and the petiole at the base of the plant expands and thickens.

The money tree gets its name because its thick leaves are arranged neatly, much like copper coins. The height of the tree is generally 50-80 cm, and there are very large tubers under the ground, with a diameter of 5-8 cm. The aboveground part has no main stem, and the feathery compound leaves are drawn from the top of the tuber. Each leaf axis has 6 pairs of opposite or nearly opposite leaflets. The leaves are ovate, thick leathery, dark green and metallic luster. Here is a detailed introduction to how to raise the tree.

The leaves of the money tree are yellow. I don't know what to do. Please poke here: what if the leaves of the money tree turn yellow?

1. Soil selection for the cultivation of Artemisia mandshurica

6. Prevention and control of diseases and insect pests in the culture of Artemisia mandshurica

The main results are as follows: (1) Leaf tip scorch: it is common in production, mainly on new leaves, leaflet tip yellowing at first, then scorched yellowing, and also leaf yellowing.

(2) Stem rot: 50% thiophanate methyl, 800 times of sulfur suspension or 50% chlorothalonil + 600 times of sulfur suspension can be sprayed once a week for 3 or 4 consecutive times, and the control effect is better.

(3) Brown spot: at the initial stage of the disease, 50% carbendazim wettable powder 500 times solution or 0.5% carbendazim 1.0% Bordeaux solution or 40% chlorothalonil 500 times solution, sprayed once a week for 3 times 4 times, the control effect is better.

(4) White silk disease: 1000 times of 50% compound Yinhujing wettable powder or 50% chlorothalonil can be used in the onset season.

7. Matters needing attention in the cultivation of Golden Tree

The main results are as follows: (1) the tree likes warmth, the suitable growth temperature is 15: 25 ℃, it is not tolerant to low temperature, grows slowly when it is lower than 10 ℃, stops growing when it is below 5 ℃, and may cause main chilling injury. The money tree is more shady, can grow in darker places, and its leaves can glow. Generally speaking, the shading degree of the tree should be up to 90% in the cultivation and production, and the strong thread will cause the leaves to turn yellow. When planting money trees, too much water can easily lead to rotten balls.

(2) the height of accessory plant 25~50cm. There are tubers in the ground. Pinnately compound leaves drawn from the ground, leaflets to cattle, Mao-shaped, apex acute, entire, thick leathery, glossy. The cow is strong, shade-tolerant, early-resistant, suitable for garden shade beautification or potted plants.

(3) the money tree is not very strict with the light and can be placed indoors for a long time to watch. Summer should be placed in a place where there is no direct light, otherwise it is very easy to cause young leaves to be burned.

(4) the money tree should be moved to a place where the indoor light is brighter in winter, less watering, no fertilization, and the temperature should be maintained at about 10 ℃ room temperature. It is watered about half a month in winter, once a week in spring and autumn, and once every three days in summer.

8. The breeding method of Chimonanthus chinensis

The propagation methods of Artemisia angustifolia include split propagation and cutting propagation.

Cutting method can be used to propagate in spring, summer and autumn. The object of cutting can be a mature and thick single leaf, a single leaf axis or a leaf axis with 2 leaves, and the human-soil depth of the leaf axis is 1 inch, 3 cycles, 1 inch, 2, 2 of the total length. After inserting the soil, spray through the water. Put it in a shaded place and keep the ambient temperature of 2527 ℃. According to the degree of dryness and wetness of the soil, spray the leaf surface once or twice a day to keep the substrate slightly moist.

There are latent buds on the tubers. During meristem propagation, the tubers can be cut into small pieces with 2 or 3 latent buds. Chimonanthus chinensis can use its leaves for cutting propagation. After inserting the leaves into the seedbed, a very small bulbous stem could be formed at the base of the leaves after 10-14 days, after which the bulbs continued to expand and latent buds grew on the tubers, and plantlets could grow after 2-3 months of culture. The growth of cutting propagation is relatively slow and the propagation coefficient is low. Large-scale production can be propagated by tissue culture.
