Passion fruit pests and diseases are serious, how to eliminate and prevent them?

Passion fruit anthracnose mainly harms passion fruit and fruit stalk, young fruit will appear water-soaked black spots, yellow halo spots appear around the spots, the fruit appears concave and convex in the later stage, and finally the fruit falls, the fruit stalk appears black spots, and the fruit falls off before it is ripe. During prevention, attention should be paid to improving the light and light transmission conditions of the orchard, and draining and reducing humidity in the rainy seasonIn the early stage of the disease, mancozeb prochloraz + pyraclostrobin can be used for prevention and treatment. It should be noted that the pathogenic bacteria of the disease can also induce root rot, so it is necessary to pay attention to soil maintenance and sanitization, such as increasing the application of live soil monarch compound bacteria.

<> common diseases that harm the growth of passion fruit are mainly the following, let's elaborate on them below: the first is called mosaic disease virus disease, when passion fruit is replaced with this disease, the leaves of passion fruit will show a flower and leaf shape, and light yellow spots will appear on the leaves, Choose clean soil for planting, maintain the soil moisture content in the field, prevent water accumulation, stay away from all kinds of melons, nightshade vegetables and bananas, and remove the burned diseased leaves and branches in time. Red Spider:

The insect body is small, it is difficult to find with the naked eye, for the disease symptoms are the leaves turn yellow, the hatchling, when this symptom appears, the back of the leaf should be carefully examined, such as the size of the needle tip of the red spider, should be sprayed in time to prevent and control. available"Dimethoate"、"Dimethoate"、"Insecticidal phosphorus"Apply a spray.

Stem base rot: ** high cost, should focus on prevention. It is necessary to pay attention to soil management, keep the orchard ventilated and transparent, reduce stem wounds, and choose fludioxonil + potassium permanganate as a timely preventive agent in high temperature and rainy periods.

At the beginning of the disease, scrape the diseased part, and use methyl frost and mosaic disease as a worldwide viral disease, not only on passion fruit, but also on the leaves at the onset of the disease and the appearance of disease spots, and in severe cases, the leaves will shrink and deform, and will also cause flower deformities and sparse flowers when flowering. The plants grow weakly, dwarf, and bear very little fruit.

Agricultural control methods of mosaic disease: First, choose an orchard where passion fruit is planted, do not choose a vegetable plot that has been planted with melons and fruits, and do not choose a nearby land where such fruits and vegetables have been planted. Second, passion fruit should be grown using virus-free cultivation techniques.

Passion fruit seedlings should be sprayed with pesticides during the flowering and fruiting process, or some bee-like things should be cultivated.

First of all, the branches and leaves with particularly serious pests and diseases should be cut off, and some pesticides can be sprayed to control the pests and diseases of passion fruit.

Spray some pesticides, pesticides can get rid of bugs and prevent insect infestations.

We should spray pesticides to prevent pests and diseases, so that it is fine, and we should get rid of all these pests and diseases, and we should water them more.

The main diseases of passion fruit are mainly mites, leaf miners, flower and fruit diseases and other diseases. First of all, we have to introduce how to prevent this

We need to choose the right soil for cultivation, and we need to maintain some water content in the field to prevent this water accumulation, and we also need to remove some burned diseased leaves, diseased branches and so on. It can remove some diseased leaves and branches in time, and stay away from all kinds of melons, eggplant, fruits and vegetables and bananas.

We can also use some drugs to prevent and treat it, such as cataplexy: use 600 times the solution of cataplexy, for example, there is also superficial patches: we can use 600 to 800 times the liquid of light yellow, and some of the avermectin:

6,000 to 10,000 times the liquid can be used. Of course, it is also very important for us to do some necessary protective measures, we mainly focus on prevention, supplemented by comprehensive prevention and control, and advocate some ecological prevention. In addition, we prohibit the use of pesticides 30 days before fruit picking, because it will cause harm to the human body.

The above is my sharing of some knowledge points on passion fruit pest control.

The method of prevention and control is to spray some drugs, fertilize and disinfect the soil when planting, and maintain the passion fruit during the growth process, 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, do a good job of preventing insect pests in advance, control the temperature, and 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 prevent it, and different drugs are different.

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 are planted 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.

Summary. Hello dear, there are 2 reasons for passion fruit rotten, one is watering problem, and the other is light problem. The moisture of passion fruit is uneven, the water is too dry or too wet, and during the fruit expansion period, such as sudden heavy rain after a long-term drought, the fruit absorbs too much water and expands, and the peel is easy to burst and crack.

Therefore, it is necessary to do a good job in water management, so that the weather is sunny and not dry, and the rain does not sink the roots. Passion fruit orchards with weak trees, poor lighting, poor ventilation and partial nitrogen fertilization are prone to fruit splitting. Soil is also an important factor affecting fruit cracking, and fruit cracking is serious in orchards with poor soil drainage, severe compaction, poor permeability, and soil acidification. It is recommended to increase the application of organic fertilizer to enhance the ability of soil water and fertilizer retention.

What causes passion fruit rotten? How to prevent metallurgy?

Hello dear, there are 2 reasons for passion fruit rotten, one is watering problem, and the other is light problem. The moisture of passion fruit is uneven, the water is too dry or too wet, and during the fruit expansion period, such as sudden heavy rain after a long-term drought, the water absorption is too large and the peel is easy to burst and crack slowly. Therefore, it is necessary to do a good job in water management, so that the weather is sunny and not dry, and the rain does not sink the roots.

Passion fruit orchards with weak potholes, poor lighting, poor ventilation and partial nitrogen fertilizer are prone to fruit cracking. Soil is also an important factor affecting fruit cracking, and fruit cracking is serious in orchards with poor soil drainage, severe compaction, poor permeability, and soil acidification. It is suggested to increase the application of organic fertilizer to enhance the ability of soil mold and water and fertilizer conservation.

Precautions for passion fruit planting 1, passion fruit do not apply herbicides and pesticides, do not use systemic herbicides (such as glyphosate), spray other herbicides not excessively, and strictly prevent the liquid from seeping into the soil to hurt the roots. 2. Do a good job of pruning and thinning the leaves of passion fruit, especially the first.

When the second and third batches bear fruit, the overlapping vines and flowerless vines on the plants should be cut off, and the leaves should be properly thinned to make the fruit shed well ventilated and transmitted, and at the same time avoid nutrient consumption. 3. Strengthen the prevention and treatment of pests and diseases, and prevent the occurrence of major diseases such as epidemic diseases and stem base rot.

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.

1. Select good plants: for future planting, the selection of plants with good genes saves time and effort, it is recommended that planting friends choose plants with strong resistance to plants, and cultivate healthy and strong plants in the early stage.

2. Early detection and: The prevention of passion fruit virus disease should be detected early, and pesticides should be sprayed in time to prevent the continuation of the disease in the early stage of detection. A mixture of fungicide and octamine acetate should be used for prevention and**, while the occurrence of aphids and other pests should be well controlled.

High-efficiency liquid fertilizer is used for foliar spraying, spraying 2-3 times, once every 7-10 days, to weaken virus activity, accumulate nutrients, enhance plant fiber, improve resistance, control plant diseases, and restore normal growth of diseased plants.

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.
