What to do when the iron tree grows insects? pest control of the iron tree / 2 insects and 2 diseases are sprayed with medicine.

I believe many flower friends know that the iron tree is poisonous, but even so, some people still keep it at home because the iron tree is really good-looking. However, in the process of breeding, because of negligence, the iron tree will also grow insects and get sick, which will destroy its ornamental. So, what should we do if the iron tree grows worms? The following are four kinds of iron tree pest control, follow the editor to have a look!

1. Iron tree worms, spray with medicine

In the process of breeding iron tree, because of high temperature, dryness, poor ventilation, high air humidity and other factors, the plant will grow insects and get sick. Among them, the main insect pests are shell insects and small gray butterflies, and the main diseases are white spot disease and coal pollution disease. Once the long worm gets sick, it will affect the growth of the iron tree, so as soon as it is found, we should immediately spray to prevent and cure it. Specifically, you can refer to the prevention and control of diseases and insect pests.

II. Disease and insect pest control of iron tree

1. Scale insects

The iron tree has strong adaptability and is rarely affected by diseases and insect pests, but its leaves are also vulnerable to shell insects at high temperature, dryness and poor ventilation. The insect sucks the sap from leaves and twigs with stinging mouthparts, resulting in yellowing of iron tree leaves and death of branches or leaves in severe cases.

Prevention and control methods: when there are few shell insects, you can brush them off with a brush and rinse them with water; when there are many shell insects, spray 50% omethoate emulsion or 50% monocrotophos in time, which has a special effect on shell insects, and the control effect can be achieved in one time.

2. Small gray butterfly

In addition to shell insects, the small gray butterfly is also one of the main pests of the iron tree, which usually occurs from May to November. The insect mainly bites on the tender leaves of the iron tree, causing the plant not to send new leaves all the year round and lose its ornamental value.

Prevention and control method: knowing the habits of the insect, flower friends can watch it every day from June, and spray it in time after finding the small gray butterfly. The medicament can choose 21% to kill EC 1000 times, 20% chrysanthemum EC 800 times 1000 times, 5% Fuling 2500 times 3000 times, and so on.

3. Coal pollution disease

Coal fouling disease, also known as black mold and soot disease, is one of the main diseases of iron tree. The disease is mainly harmful to the leaves, and a black mildew layer is formed on the surface of the affected parts, which looks like a layer of soot. This will seriously hinder the photosynthesis of the iron tree, weaken the growth potential, and in some cases cause the branches and leaves to wither and die.

Prevention and treatment methods: when the above diseases are found, it can be manually scrubbed or sprayed with 80-1000 times liquid of Bishi shark, 70% methyl topiramate and other agents for prevention and treatment.

4. White spot disease

In addition to coal fouling, iron trees are also prone to white spot disease at high temperature and high air humidity. The disease mainly harms the leaves of the iron tree, making the diseased leaves appear irregular disease spots, and the disease spots will gradually expand in the later stage, and purplish red or reddish brown spots can be seen on both sides.

Prevention and control methods: after autumn, the diseased leaves should be completely cut off and burned centrally to reduce the source of the disease. at the initial stage of the disease, carbendazim 50% wettable powder or topazine 70% wettable powder can be mixed with water 1000 times, and the diseased plants can be sprayed in the early morning.

With regard to the prevention and control of iron tree diseases and insect pests, the editor has introduced this. I believe that if you encounter iron tree worms or get sick again, you should know how to do it! Generally speaking, as long as it is maintained according to the breeding method of the iron tree, it will generally not be affected by diseases and insect pests. Of course, if the iron tree worm is sick, don't be afraid, just follow the above method to solve it. Finally, may everyone's iron tree grow beautifully.

1. Red spider

To say that the Brazilian iron tree worm, the first consideration should be the red spider, because it is the enemy of foliage plants. It is understood that red spiders mainly use mouthparts to pierce the leaves of the Brazilian iron tree to suck juice, so that the chlorophyll of the plant is destroyed, causing the leaves of the Brazilian iron tree to turn yellow and even detach.

Prevention and control methods: for red spiders, we should always take precautions and check the back of leaves in time. When individual leaves are damaged, insect leaves can be removed; when more leaves are damaged, propargite, dimethoate, Huachongjing and other drugs should be sprayed as soon as possible to control them.

2. Spodoptera litura

Among the pests of Brazilian iron tree, sugarcane moth needs to be considered, which is a potentially dangerous insect. After being attacked by the sugarcane moth, the fleshy part under the epidermis of the Brazilian iron tree is completely emptied and replaced with insect dung, and the plant will face death.

Control methods: after the discovery of sugarcane moth, quick-killing agents such as chrysanthemum EC can be used to irrigate the injured parts of the stem, and trichlorfon is used to make poisonous soil and sprinkle it in the topsoil of flowerpots.

3. For grain wood bark beetle

A pest that harms the Brazilian iron tree, it mostly appears in the growing period, the harm is very serious. To the grain wood bark beetle, the body size is small, the insect feces is slightly fine, and usually occurs with the sugarcane moth. Therefore, after being attacked by the insect, the harm of the victim is basically similar to that of the sugarcane moth.

Control method: once it is found that the grain beetle should be sprayed immediately, 40% omethoate EC 1000 times mixed with 90% trichlorfon 1000 times solution can be effective every 7 to 10 days, 4-5 times in a row.

4. Anthrax

Anthracnose is one of the most important diseases and insect pests in Brazil, which is easy to occur in rainy season, poor indoor ventilation and excessive humidity. If the leaf tip of the Brazilian iron tree turns black and the leaves have yellow spots, it should be suffering from anthracnose.

Prevention and control method: after anthracnose is confirmed, spray 75% chlorothalonil 600 times or 50% thiram wettable powder 500 times, once every 7 to 10 days, three times in a row. In addition, fertilizing once every 20 to 30 days during the peak growing season can effectively reduce the occurrence of this disease.

5. Epidemic disease

Another Brazilian iron tree disease, which mainly harms the leaves and the ground of the plant, resulting in water-immersed spots on the diseased leaves, then quickly expands to black-brown rot, resulting in fallen leaves, sometimes with a thin white mildew layer on the damaged surface of the leaves.

Prevention and treatment: cut off the diseased leaves in time and burn them or bury them in soil in order to reduce the source of the disease. When the disease occurs, it can be sprayed with 72.2% Pulicol water agent 600-700 times for prevention and treatment.

6. Grey mold

In the process of breeding Brazilian iron tree, if the soil is too wet, lack of light, and poor ventilation, it is easy to suffer from gray mold. After suffering from the disease, the leaves and petioles of the Brazilian iron tree are gray and water-stained, and even the tissue softens to rot.

Prevention and treatment methods: find the above symptoms, cut off the diseased leaves in time to reduce the source of the disease; at the initial stage of the disease, 1000 times of methyl topiramate wettable powder can be sprayed for prevention and treatment.

Flowerpot: a flowerpot for a Brazilian iron tree, which needs to be selected according to the stem of the plant. Generally speaking, 12-20cm caliber pots are fine, but if there are 3 stems of Brazilian iron trees, use 25cm caliber pots.

Soil: according to the growth habits of Brazilian iron tree, it likes soil that is loose and fertile, has good drainage and contains humus. In this regard, the editor recommends that we choose peat soil, rotten leaf soil, pastoral soil, perlite mixed according to the same proportion of soil.
