Disease Control of Cat's Eye Taro

1, white silk disease

The incidence of white silk disease was higher. When the plant is infected with white silk disease, the stems and leaves near the soil will rot and change color, and the white fungus silk virus will appear in radial form. Then the infection will expand and turn dark brown, spread throughout the plant and eventually cause the plant to die. It should be noted that July and August are the high incidence period of white silk disease, and careful attention should be paid to the growth of plants. If infected branches and leaves are found, remove them in time to avoid expansion.

control methods

Because white silk disease occurs mostly in soil moisture is too large or soil nutrient deficiency. Therefore, in order to carry out control, it is necessary to ensure that the soil moisture is moderate and the fertilizer is sufficient. Secondly, keep the plants in a cool and ventilated place, and regularly trim the branches and leaves to avoid being too dense and prone to bacterial infection; if diseased plants are found, they should be thoroughly cleaned up and replaced.

Control of white silk disease of arrowroot

The incidence of white silk disease was higher. When the plant is infected with white silk disease, the stems and leaves near the soil will rot and change color, and the white fungus silk virus will appear in radial form. Then the infection will expand and turn dark brown, spread throughout the plant and eventually cause the plant to die. It should be noted that July and August are the high incidence period of white silk disease, and careful attention should be paid to the growth of plants. If infected branches and leaves are found, remove them in time to avoid expansion.

Control methods: white silk disease occurs in soil moisture is too large or insufficient soil nutrients. Therefore, in order to carry out control, it is necessary to ensure that the soil moisture is moderate and the fertilizer is sufficient. Secondly, keep the plants in a cool and ventilated place, and regularly trim the branches and leaves to avoid being too dense and prone to bacterial infection; if diseased plants are found, they should be thoroughly cleaned up and replaced.

leaf spot

More common in leaves and leaf sheaths. When the disease was reddish brown spots continue to expand, no obvious halo around. Leaf spot disease has no fixed onset period and is possible all year round, but the incidence probability is greater in early autumn, so prevention and control should be done well. When the disease occurs, a large number of leaves will dry up and die. The infection of diseased plant residues is the source of initial infection.

Control methods: leaf spot disease may be caused by insufficient fertilizer, so should increase fertilizer, enhance disease resistance; second, to remove the diseased branches and leaves in time, eradicate the source of bacteria; spray chlorothalonil wettable powder antibacterial solution before the disease to prevent

Pest control of cat-eye arrows-suffering from scale pests

Shell pests often appear on the edge or surface of leaves, both front and back are possible, especially the back is not easy to find, should pay more attention. Scale insects suck plant sap, if the pest is light, it will make the leaves yellow and wither, affecting the beauty of the plant type. Serious words will lead to leaf drying, plant lesions until death; in addition, the wound after scale insect bite is more sensitive, easy to suffer from virus, must be dealt with in time. The most annoying point is that scale insects have a strong reproductive ability. Once found, they must be eradicated in time, otherwise they will be difficult to deal with. If necessary, they will need to spray pesticides.

Control methods: pay attention to plant ventilation, ensure that it grows in a relatively cool place. If pests have occurred, pesticides such as dichlorvos can be sprayed. Spray once every other week, spray continuously for 2-3 times.

Cat-eye arrowroot infested by red spiders

Red spider pests are more common, absorbing nutrients from leaves, resulting in plant nutrition imbalance, affecting its normal growth and development. Such pests are often associated with excessively dry environments and high temperatures, so extra care should be taken in summer.

Prevention and control methods: keep the environment ventilated, avoid easy infection of germs; red spiders encounter water difficult to reproduce, can spray water to the leaves from time to time to maintain humidity, can effectively avoid red spiders growth. If the disease has been encountered, dicofol emulsifiable concentrate can be sprayed to kill, it should be noted that because pesticides almost do not cause harm to eggs, so it is necessary to wait until the eggs are broken and then spray the larvae before they can be completely removed.

What is the role of cat's eye arrowroot cultivation method?

Nowadays, people like to cultivate plants indoors to beautify and green the home environment. At present, there are many kinds of plants that can be cultivated indoors. Cat-eye arrowroot is one of them, but many people don't know much about cat-eye arrowroot. What is the role of cat-eye arrowroot? What are the breeding methods of cat's eye arrowroot? Let's get to know it together with Xiaobian.

What does cat's eye do:

When it comes to what role cat-eye arrowroot has, usually cat-eye arrowroot originated in tropical and subtropical areas, shade tolerance, easy cultivation, and colorful, elegant shape, its main role in addition to viewing, there are certain purification effects, specifically to see the following introduction:

1. Appreciation value:

Cat-eye arrowroot has the characteristics of shade tolerance, and good feeding, and at the same time has a beautiful growth form: the overall plant is cluster-like, broad leaves, dense growth, stretching upright appearance, due to the main veins of the leaves on both sides of the white belt and dark green belt interwoven into a feather-like arrangement, so bright color, colorful, in addition, its leaves are also distributed with black spots, like panda eyes, round interesting, this is also the origin of its name.

Cat-eye arrowroot is suitable for home decoration and beautification, used to decorate balconies, studies, bedrooms, etc., adding elegance, but also can be used to decorate commercial places, such as shops, hotels, in South China can often be seen planted in courtyards, parks, roads and other places, as landscaping.

2, purification effect:

Purifying the air is also a big role of cat-eye arrowroot, although it can not be compared with hanging orchid, but also can not underestimate the role of cat-eye arrowroot purifying the air, cat-eye arrowroot absorption of formaldehyde, ammonia and other harmful gases is far better than many plants, therefore, for just decorated houses, cat-eye arrowroot is also a good choice.

The above is a brief introduction to the role of cat-eye arrowroot. I believe that after the introduction above, we will have further understanding and understanding of cat-eye arrowroot. The leaves of cat-eye arrowroot are wide, and the round black spots on the leaves are just like the eyes of pandas. It is interesting. This is also the main reason why people like to cultivate it indoors. However, the cultivation of cat-eye arrowroot is also different from that of other plants. What are the cultivation methods of cat-eye arrowroot? Let's take a look at the following introduction:

The breeding method of cat-eye arrowroot:

1. Temperature:

Cat-eye arrowroot originated in tropical and subtropical regions, high temperature resistance, suitable for growth environment of 20-30℃, winter growth temperature should be maintained at about 16-18℃ is the most appropriate.

2. Light:

Shade-tolerant plants, like semi-shade, should be placed in bright indoor light, avoid direct sunlight, exposure, etc., to avoid burning leaves, summer to do a good job of shading and ventilation.

3. Watering:

During the growth period of us us, sufficient watering should be done to keep the pot soil moist. Meanwhile, attention should be paid to avoid causing water in the soil to prevent root rot and even death of the plant. As the leaves of us us are larger and the water evaporates rapidly, it is necessary to maintain a higher air humidity around them. Spray the leaves frequently to keep the air around the leaves moist, which is conducive to the growth and extension of the leaves. Once the leaves are found to curl and shrink, It means the plant is in a state of water shortage.

4. Fertilizer:

Follow the principle of "frequent application and thin application", stop fertilization during winter dormancy period and continuous high temperature in summer.

5, change basin work:

Every other year for a basin, it is appropriate to select fertile, loose, good permeability and drainage, containing rich humus slightly acidic soil.

6. Pest control:

Common pests mainly include scale insects, red spiders, etc. For scale insects, according to the disease situation, 40% omethoate 1000 times solution or 50% dichlorvos 1000 times solution, 2.5% deltamethrin 3000 times solution can be sprayed for control. For red spiders, it is generally controlled during the adult period after egg hatching, and 20% dicofol EC 1000 times solution can be used. It can also be sprayed with 40% omethoate EC 1000 times solution.

7. Disease control:

Common diseases mainly include white silk disease and leaf spot disease. For white silk disease, quintozene (70% of soil weight) can be added to disinfect soil, remove diseased plants and diseased soil, add new soil and ventilate well. For leaf spot disease, diseased leaves should be removed in time, basal fertilizer should be added to enhance disease resistance.
