How to prevent passion fruit pests and diseases?

1. Stem rot, which is a fungal disease, its early symptoms are water-stained, then brown, and slowly spread, so that the base of the main stem is soft rot, resulting in the chronic death of passion fruit plants. The main control measures are to strengthen the drainage of the orchard and avoid damage to the passion fruit stems.

2. Blight, which is also a fungal disease, after the passion fruit seedlings are infected, the initial manifestation is that there are water-stained lesions on the stems and leaves, and then it spreads rapidly, causing the leaves to fall off or the plant to die. The control measures are mainly in the selection of seedlings to carry out strict selection of healthy branches and seedlings, if found disease can be carried out by chemical drugs**.

You can use plant-specific insect repellent to spray evenly on plant leaves, and it should not be watered during the medication, otherwise there is no effect.

It is necessary to select virus-free vines for seedlings, and strengthen the management of passion fruit to enhance the resistance of plants to diseases and pests. The orchard must be frequently removed from weeds, dead branches, diseased branches, and weak branches, and then burned.

Cataplexy:Cataplexy occurs in the seedling stage, when it occurs, the stem of the plant has a water-stained shape, and spreads rapidly, until the stem of the plant withers and lodging with the ground, if the ground humidity is large, a layer of white mildew will grow around the plant, and then the leaves and roots all rot and die.

Prevention and control methods: choose plots with high terrain, low groundwater level and good drainage performance when sowing seedlings, disinfect and sterilize seeds and soil before planting, and regularly spray diluted potassium dihydrogen phosphate when seedlings to prevent diseases. In addition, the seedling stage should pay attention to ventilation and light transmittance, and watering should be based on the soil and climate.

Mosaic disease:Mosaic disease is a worldwide viral disease, not only on passion fruit, the leaves begin to fade and appear lesions at the onset of the disease, and the leaves will shrink and deform when they are severe, and will also cause flower deformities and scarcity of flowers during flowering. The plants grow weakly, dwarf, and bear very little fruit.

Prevention and control methods: cultivate virus-free, disease-resistant plants, strengthen management, increase plant resistance, mosaic disease is transmitted by many insects, so eliminate vector aphids and other insects, find diseased leaves, diseased plants and clean up in time.

Passion fruit planting precautions.

Passion fruit likes light, daily maintenance should let passion fruit bask in the sun, the more light is more beneficial to the growth of the plant, and can make passion fruit grow vigorously, more flowers and fruits, if there is a lack of light, the stems and leaves of passion fruit will be weak, less flowering or even no flowering.

Passion fruit is originally a tropical plant, so in the daily maintenance of passion fruit to give a relatively high temperature environment, the south of the high temperature area can be open in winter, the cold area in the north of the winter to move into the indoor maintenance, and always pay attention to the maintenance of the environment ventilation.

The method of prevention and control is to spray some drugs, to fertilize and disinfect the soil during planting, and to maintain passion fruit during growth, so as to prevent insect pests.

In the passion fruit growth cycle, spray some pesticides around the passion fruit, prune the passion fruit branches, pay attention to the environment, add more fertilizer, and sprinkle some salt on the land to prevent insect pests and reduce passion fruit insect pests.

It is necessary to use pesticides for prevention, or to do a good job in water and fertilizer management, or to apply fertilizer regularly, to prevent insect pests in advance, to control the temperature, and to pay attention to the growth process of passion fruit.

When planting passion fruit will encounter diseases in the fruit, usually fruit farmers will choose to spray drugs on the fruit to ** and prevent, and different ** drugs are also different.

1.Passion fruit wilt.

Passion fruit wilt is a disease caused by a fungus that usually causes all or part of the plant to wilt and, in severe cases, die.

The main symptoms of the disease are yellowing, wilting, and wilting of the leaves, and gradually develop from bottom to top, eventually leading to the death of the whole plant. Pathogenic microorganisms enter the plant after infecting the roots of passion fruit and spread upward through the root system, causing damage to the plant.

Ways to prevent passion fruit wilt include applying more organic fertilizer, watering according to soil moisture status and adequate sunlight exposure, applying jujube fertilizer with plant ash, maintaining a reasonable plant density and maintaining a good ventilation environment.

2.Passion fruit anthracnose.

Passion fruit anthracnose is a parasitic disease caused by the bacterium anthracnose, in which the pathogen infects flowers, fruits, leaves and stems, causing the death and withering of plants.

The disease often manifests as small ulcers on the plant, which then spreads to different areas and develops into a complete circular necrotic area with black charring.

Methods to prevent passion fruit anthracnose include cleaning up the agricultural environment, removing infected flowers, fruits, stems, leaves, etc. as early as possible, using healthy seedlings, and spraying plants with fungicides that are effective in preventing anthracnose. Acres of Exciting Hall.

3.Passion fruit blight.

Passion fruit blight is a disease caused by the fungus, the pathogen is mainly parasitic on the root neck, will infect the roots and stems of the plant, and eventually lead to the death of the whole plant.

The disease is characterized by the gradual roll-up and yellowing of the leaves of the plant, after which it dies completely. Healthy seedlings are also susceptible to infection in diseased areas, resulting in the benefit of the entire plant area.

To prevent passion fruit blight, it is necessary to choose healthy seedlings, pay attention to soil ventilation and air permeability, reasonably control soil moisture, regularly carry out soil removal and leaf removal, and loosen soil between rows to maintain the growth of plants.

Conclusion. Passion fruit is a fruit loved by many people, but it is also threatened by a variety of diseases. In order to protect the safe production of passion fruit and increase the yield, we need to pay attention to the prevention and prevention of passion fruit diseases, and take corresponding measures and methods in time to reduce disease infection.

At the same time, in daily life, it is also possible to strengthen the care of plants and create beneficial conditions for the healthy growth of passion fruit.

First choose the right soil, then fertilize it scientifically and water it properly, and you can grow passion fruit. First of all, it is necessary to choose varieties with strong resistance to diseases and pests, and secondly, spraying drugs to control pests and diseases, and we must do a good job in water and fertilizer management and pay attention to drainage.

Passion fruit is a common tropical fruit, and passion fruit cultivation requires a complex process. During the growing season, it is necessary to pay attention to field management to prevent diseases and insects.

This unique plant grows in the tropics, grown from seeds, and we should control the temperature and humidity, water less, increase ventilation, and use pesticides to prevent passion fruit insects.

We can plant passion fruit saplings in the soil, and we should spray passion fruit with some pesticides. Passion fruit seedlings can grow fruit when they grow well in the soil, and when it has corresponding pests and diseases, we should spray it with pesticides.

These strange creatures grow in the cold zone, and those planted through seeds should control the temperature and humidity, water less, add ventilation, and manipulate pesticides to prevent passion fruit from growing insects.
