Tomatoes have rotten fruits and yellow leaves, what is the cause?

I think the main reason should be too much watering, or no water, the sun is too dry, this phenomenon will occur, my family used to grow tomatoes, generally because of these two conditions will rot the fruit.

I think it probably rained, got drenched, and then waterlogged, so its leaves rotted. Hurry up and do moisture-proof treatment.

If the tomatoes are planted in a relatively low-lying location, and the stagnant water is not discharged in time, soak the tomatoes with stagnant water for a long time, which is also the cause of the yellow leaves and rotten fruits of the tomatoes.

It is caused by a lack of phosphorus and potassium. Generally speaking, tomatoes have rotten fruits and yellow leaves, which is a lack of nutrients, and you can supplement him with some compound fertilizer.

Tomatoes enter the fruit stage after the phenomenon of rotten fruit, mainly caused by soft rot, anthracnose, brown rot, etc., in the planting process must be prevented and treated early to avoid losses.

It is likely to be caused by a lot of water, or it may be caused by a lack of fertilizer, so be sure to pay attention to the growth of tomatoes and the drainage of the soil.

It is very likely to be caused by a bacterial infection, so be sure to pay attention to the growth of the plant, or it may be caused by too much watering.

Introduction: Tomato scrambled eggs, I believe many people like to eat them. So does anyone know how tomatoes are made?

When I was a child, my grandmother had a small garden in front of her house, and sometimes she would grow tomatoes. However, sometimes the tomatoes have rotten fruits and yellow leaves. At that time, it was not very clear what caused it, but it was later found out after investigation.

When I first saw the rotten fruit and yellow leaves of the tomato, I thought that the tomato was unhealthy, and it had some minor problems, but what caused these problems? The first thing to pay attention to is the fertilization problem, and we must pay more attention to the fertilization of tomatoes when planting. When fertilization is not done properly, over-concentration of fertilizer or other reasons can lead to fertilizer damage, and the symptoms of fertilizer damage are that the entire tomato plant will wilt, the leaves will turn yellow, and the flowers and fruits will fall.

Therefore, pay more attention to the time of fertilization and the amount of fertilization, including the concentration of fertilizer.

Lack of calcium, tomato photorespiration, produces various organic acids, among which oxalic acid can cause poisoning, and then onset. It is also possible that the water supply is out of balance, and the temperature is higher when entering the large number of fruits, but the evaporation of the leaves is larger, and the required water is taken away by the leaves, resulting in water loss and fruit rot.

First of all, pay attention to the time when fertilizing. The second is to pay attention to the concentration of fertilization in the process of fertilization, so as to avoid excessive or too little concentration of tomatoes that cannot bear fruit normally. The second is to give birth control tomatoes with plenty of water, especially during fruiting.

The fruit basically appears in a period of time, and if it is not hydrated enough, it will lead to rotten fruit. After that, we should also pay more attention to the pests in the pests, and if there are too many, we should deal with them in time. Avoid pests that can corrode the plant and lead to a reduction in tomato yields.

Infected with the virus, or because of excessive fertilization, because of excessive watering, we must pay attention to the way of breeding, pay attention to the light.

Because it is not fertilized in time, in fact, tomatoes also need to be fertilized, otherwise rotten fruits and yellow leaves will appear.

I think it's probably due to lack of water. If the tomato plant is short of water, it will not have enough water to supply the leaves and fruits. This causes the leaves to turn yellow and the fruit to rot.

In drought, when tomatoes lack water, the leaf vacuoles will shrink, the chloroplast will partially die, and yellow leaves will appear, which need to be watered frequently; If the fertilization concentration is too high, the roots will be burned, and the leaves will turn yellow without sufficient nutrients, so it is necessary to pay attention to diluting the fertilizer when fertilizing; If the temperature is too low, the nutrient transport of tomato plants will be blocked, and the leaves will turn yellow, which can be solved by building greenhouses and mulching.

1. Drought. The reason for the yellow leaves of tomatoes may be drought, and frequent watering is required in the dry and rainy season to ensure that the tomatoes have sufficient water absorption. When tomatoes are unable to absorb water from the soil, the leaf vacuoles will shrink, and the chloroplasts will partially die, showing the phenomenon of leaf wilting and yellowing.

2. Fertilizer. Tomatoes may appear yellow leaves because of excessive fertilizer concentrationWhen the fertilizer touches the roots of tomatoes, the high concentration of fertilizer will absorb water from the root cells with low osmotic pressure, resulting in dehydration and even death of the roots of the tomatoes, and the ground part shows the symptoms of yellow leaves, so it must be diluted when fertilizing.

3. Lack of nutrition.

The lack of elements needed for the growth of tomatoes in the soil will also lead to yellow leaves, and tomato leaves need a variety of elements to grow, and when the lack of elements will cause the leaves to underdevelop and yellow leaves. Multi-element compound fertilizer should be used as much as possible for daily application of fertilizer, and organic fertilizer can be used as base fertilizer before planting.

4. The temperature is too low.

The reason for the yellow leaves of tomatoes may also be that the temperature is too low, the suitable growth temperature of tomatoes is 20 30, if it is lower than 10, it is necessary to keep warm to prevent low temperature from causing poor nutrient transportation and yellow leaves. Generally, you can build a greenhouse and cover the soil surface with a layer of plastic film to keep warm.

Tomato yellow leaves are caused by root damage, poor ventilation, wound infection, if it is overwatering caused by root watering, then to cut off the water treatment, and then watering after the soil is about to dry out, usually strengthen ventilation, plant densely planted to knock off some leaves, in addition to the tomatoes to choose a sunny day, before and after watering, rainy weather do not interrupt. Cover search.

1. Root damage:If the leaves of the tomatoes are yellow, you can consider whether the tomatoes have damaged their roots, such as overwatering, causing water in the soil, and the roots of the plant are stuffy, such as the root system is diseased, and the phenomenon of yellow leaves will also be shown.

2. Poor ventilation:If the leaves of the tomato are yellow, you can also consider whether the maintenance environment is ventilated, if the plant is lush and the maintenance environment is poorly ventilated, the leaves of the tomato will turn yellow.

3. Wound infection:If the tomato has yellow leaves after pruning, and the xylem inside the plant turns brown when the stem is cut open, it is most likely caused by an infection in the wound of the plant after the forking.

How to treat the yellowing of tomato leaves.

1. In view of the yellowing of tomato leaves caused by excessive watering, it is necessary to cut off the water in the short term, and then water after the soil is about to dry out.

2. In view of the yellowing of tomato leaves caused by poor ventilation, it is necessary to strengthen the maintenance environment as much as possible, and remove some leaves from densely planted plants, which can effectively reduce the occurrence of tomato yellow leaves.

3. To the tomatoes should be selected on sunny days, before and after watering, in rainy weather, not lead type to be divided, for those who have been forked and yellow leaves, all the stems and leaves in question should be cut off, and bacterial agents such as spring leimycin should be sprayed to prevent bacteria from continuing to be infected.

Yellow leaf control of tomatoes.

Tomatoes like a warm environment, it is best to provide a temperature of 15 degrees to 28 degrees during the maintenance period, it needs a lot of water to grow, but there can be no standing water in the soil, it needs to be fertilized every half a month during the growth period, and foliar fertilizer needs to be applied, which can promote the growth of leaves.

Summary. The leaves of the tomato are rolled up, which may be infected with a viral disease, which will cause the affected leaves to fade green, shrink, and curl, and also cause the infected plants to become short, affecting growth. Before planting tomatoes, prevention should be done, choose varieties with strong virus resistance, soak seeds in advance for disinfection, spray imidacloprid or acetamiprid to eliminate pests that spread diseases, and spray virus A 500 times mixed with nanmycin 300 times to control diseases.

What disease does this condition appear in tomato leaves?

The leaves of the tomato are rolled up, which may be infected with a viral disease, which will cause the affected leaves to fade green, shrink, and curl, and also cause the infected plants to become short, affecting growth. Before planting tomatoes, prevention should be done, choose varieties with strong virus resistance, soak seeds in advance for disinfection, spray imidacloprid or acetamiprid to eliminate pests that spread diseases, and spray virus A 500 times mixed with nanmycin 300 times to control diseases.

Symptoms: The leaves of tomatoes are rolled up, which may be infected with a viral disease, which is transmitted by insects such as aphids and whiteflies. When infected with a viral disease, the affected leaves will turn green, shrink, and curl.

Not only will the leaves be problematic, but the infected plants will also be dwarfed, which will affect their growth. Control method: Before planting tomatoes, you should choose varieties with strong virus resistance, soak the seeds in 10% trisodium phosphate in advance, soak for about 20-40 minutes, then remove and wash, and then sow seeds.

Because viral diseases are transmitted by pests, imidacloprid or acetamiprid can be sprayed to eliminate pests, and virus A 500 times mixed with niminomicin 300 times can be sprayed to control the disease.

1. Physiological leaf curling: improper maintenance, it may cause physiological leaf curling, which is generally due to the following reasons, namely, soil drought and lack of water, root damage, poor water absorption, lack of nutrients and insufficient nutrition. 2. Effects of drug damage:

If the concentration is too large or the drug is not used properly, it will cause damage to the tomato plant, and it will also cause the pesticide damage and cause the leaves to curl. 3. Premature topping: If the tomato plant is topped too early, it will also lead to the growth of axillary buds, which will affect the nutrient delivery and eventually lead to the aging and curling of the leaves.

There is tomato leaf mildew, the leaf is diseased, the front of the leaf appears irregular or oval light yellow green spot, the edge is not obvious, the back of the leaf appears gray-white to black-brown dense mold layer, and the later becomes purple-gray or dark gray to black or yellow-brown; When the humidity is high, the leaf surface lesions can also grow a mold layer, which can be treated with azimethiamine, chlorothalonil or mancozeb, iprodione or pythium, thiophanate-methyl and other sprays, with an interval of seven to ten days, and two to three times.
