Pest control of round-leaf taro

Round-leaf taro has a strong ability to resist insect pests, but it will still be plagued by insect pests due to various reasons in the process of culture, so how to control common insect pests?

Dendrolimus rotundus

This kind of shell insect is mainly pink scale, which is mostly born on the back or edge of the leaf, and the occurrence of the page is less. They will seriously affect the growth and health of plants, and even withered leaves and fallen leaves may appear in serious cases. Affected by shell insects, plants are very easy to be infected with virus. This highly fertile creature can produce many generations in a year, with a high incidence in May each year. Once it happens, the prevention and control work will be more difficult.

Prevention and cure method

For the control of shell insects, they can be sprayed at the nymph stage. At this time, most of the scale insects do not hatch, and the shell has not yet been formed, which can be killed with chemicals. 1000 times of omethoate is sprayed every 7-10 days.

Round-leaf taro red spider

The harm of red spiders to round-leaf taro is obvious, they will affect the normal balance metabolism of the plant, so that it can not develop normally. Red spiders breed very fast in high temperature and dry environment, and the harm ability is serious.

Prevention and cure method

Keep the air usually, the environment is the same, the humidity is more than 40%, often spraying water on the leaves can prevent the breeding of red spiders, you can use 20% dicofol 1000 times solution to spray.

In fact, it is not very troublesome to plant a pot of round-leaf taro at home. Round-leaf taro is not only beautiful, can beautify the room, the most important thing is the home with a touch of green flowers, even their own mood can feel happy every day!

Dendrolimus rotundus

The shell insects of round-leaf taro are mainly pink scale, which mostly occur at the back of the leaf or the edge of the leaf, and the occurrence of the page is very few. They suck the leaf sap of the plant by piercing and sucking, which seriously affects the healthy growth of the plant, and even withered leaves and fallen leaves appear in serious cases.

How to raise round-leaf taro culture methods and matters needing attention

Round-leaf taro must be familiar to many people, and it is a very common plant. Round-leaf taro has high ornamental value, so many people choose to breed it. Presumably, what we are most concerned about before breeding is its breeding method! Next, let's study together.

How to raise round-leaf taro

1. To strengthen the control of room temperature, the most suitable temperature is 18 ℃ at night and 20-22 ℃ in daytime.

2. It should be properly ventilated at noon to maintain the best planting humidity.

3. Observe and maintain, pay attention to the occurrence of diseases, and don't water too much.

4. Cut off the diseased leaves in time and isolate the diseased and disabled plants.

5. Strengthen the management of fertilizer and water, gently and slowly during watering, not too fast, to prevent spraying on the leaf surface.

Culture method of round-leaf taro

1. Temperature. Round-leaf taro likes a warm and peaceful environment, so it is not resistant to heat, is afraid of high temperature, and its cold resistance is poor. The suitable temperature for its growth environment is 18-30 ℃. When the ambient temperature exceeds 25 ℃ in late spring and early summer, it is necessary to build a shed for shade and spray water to create a cool, ventilated, moist and dark environment. Ambient temperature in winter. No less than 10 ℃. If the room temperature is less than 5 ℃, the round-leaf taro will sleep and suffer serious freezing damage. Generally speaking, at the end of autumn, taro should be moved to a sunny place in time for protection and overwintering.

2. Light condition. Round-leaf taro likes semi-shade, avoid high-temperature exposure, avoid serious burns to the leaves. It causes the leaves to be dim and dull and loses its original sense of beauty. Therefore, it should be placed in the greenhouse to replenish light in winter. In daily life, it can be placed indoors as a potted plant, and should be placed in front of a window with sufficient scattered light.

3. Water condition. Round-leaf taro likes the wet environment, so the growing season should be watered once a day, and the spray around the page and environment should be strengthened to keep it moist and not too dry. Strict control of watering in winter, basin soil is too wet will lead to poor drainage, root rot, so that the leaf withered phenomenon. When the spring is full of flowers, the plant will reproduce new leaves. The germination of new leaves should not be watered too much, along with the increase of new leaves, gradually increase the amount of water, which is conducive to the healthy growth of the plant.

4. Soil conditions. Round-leaf taro prefers well-drained, fertile and slightly acidic humus soil. The basin soil should be mixed with humus fertilizer and river sand.

5. Fertilization method. During the growing period, round-leaf taro should apply thin organic fertilizer once a week. Potted plants are suitable for viewing at home and in public places. In the high temperature season in summer, when the temperature is higher than 32 ℃, the fertilization of round-leaf taro should be stopped. At the end of autumn and the beginning of winter, stop all topdressing, otherwise it will cause rotting roots.

Matters needing attention of round-leaf taro

Round-leaf bamboo taro should make the basin soil slightly dry in winter, in order to pass the winter, usually watering should not be too waterlogged, otherwise there may be rotten roots or root diseases; if the plant is too shaded, the silver-gray stripes on the edge of green apple bamboo taro leaves will be darkened, affecting the ornamental effect. When fertilizing, we should pay attention to the ratio of nitrogen, phosphorus and potassium, do not apply nitrogen fertilizer alone, otherwise it will affect the color of leaves.

Pest control of round-leaf taro

1. Round-leaf taro scale. Control methods: for the control of shell insects, they can be sprayed in the nymph stage. At this time, most of the scale insects do not hatch, and the shell has not yet been formed, which can be killed with chemicals. 1000 times of omethoate is sprayed every 7-10 days.

2. Round-leaf taro red spider. Prevention and control methods: keep the air usually, the environment is the same, the humidity is more than 40%, often spraying water on the leaves can prevent the breeding of red spiders, 20% dicofol 1000 times solution can be used to spray.

In fact, the culture method of round-leaf taro is very easy as long as it has mastered the skills. You can start by understanding its growth habits. In the later stage of breeding, it needs strong pest, fertilizer and water management. only by doing these work well can its growth be good and its ornamental ability be high.
