What medicine is used for carob yellow leaf disease, and what medicine is used for carob yellow leaf

If only a small amount of yellow leaves appears, it is a normal metabolism. If the amount is large, it is considered a pest. Method:

Carob aphids. It is mainly carob chlorophyll, which affects photosynthesis and makes carob grow poorly and affects the fruit. Removal method:

Use 800 times of 40% dimethoate emulsifiable concentrate or 1500 times of cypermethrin to spray after the dew dries in the morning on a sunny day or before the sun sets in the afternoon.

Carob bugs. This pest sucks the tender juice of young beans with stinging and sucking mouthparts, so that the damaged beans grow and develop poorly, shriveled and thin, and the quality is inferior and inedible. Manual capture:

You can take advantage of the feigned death of the carob bugs, shake the bean stalks in the early morning or evening, and hunt and kill the bean bugs when they fake their death when they land. Drug treatment: use 25% Zhongke Meiling 1000 1500 times liquid of pesticides that are safe and non-toxic to humans and animals, and spray them in the evening on sunny days.

It can also be sprayed with 1500 times of cypermethrin in the afternoon to dusk on a sunny day.

Beanhorn zebra. This pest eats the carob flowers, making the carob flowers unfruitful. Artificial killing:

In the morning before the dew dries or at dusk, wear rubber gloves to kill. When hunting carob zebras, do not let their juice splash on the **, otherwise, it will cause allergic blisters. Drug removal:

Use 25% Zhongke Meiling 1000 1500 times solution or 90% trichlorfon 800 times solution to spray after the dew dries in the morning or evening on a sunny day.

Sterilization was carried out, and the roots were irrigated with carbendazim. The yellow leaves of carob caused by root rot need to be disinfected and sterilized in the soil, and the roots should be irrigated with carbendazim; 2. For the yellow leaves of carob caused by the lack of trace element root rot, foliar fertilizer can be appropriately sprayed to supplement nutrition; 3. If the yellow leaves of carob are caused by improper temperature and medication, it is necessary to spray the plants with Bihu and Brassinolide, and pay attention to reasonable watering and heat preservation.

Carob yellow leaf disease is generally treated with carbendazim, bihu, brassinolide and other agents**, and the yellow leaf medication caused by different reasons is also different. The leaves at the bottom of the bean turn yellow, which may be infected with root rot, so the soil needs to be disinfected and sterilized and the roots should be irrigated with domothalonil. The leaves of carob are yellow and may lack trace elements, so foliar fertilizer can be appropriately sprayed to supplement the degree of nutrition;

The leaves at the bottom of the bean turn yellow, which may be infected with root rot, and the soil needs to be disinfected and sterilized and the roots should be irrigated with carbendazim; The leaves of carob are yellow, and there may be a lack of trace elements, so foliar fertilizer can be sprayed appropriately.

1. Symptoms of yellowing of carob leaves.

There are two main cases of carob yellow leaves. One is that the bottom leaves are yellow, easy to fall off, and gradually expand upward, resulting in dead trees. The second is the yellowing of the new leaves at the top, often accompanied by falling flowers and fruits. The third is that the plant does not die, but the leaves and veins of the plant are yellowed in the middle.

2. Cause analysis.

1. Carob root rot, commonly known as "red root disease". This is a soil-borne disease, the early pathogen infects the root system, the plant is malnourished, the bottom leaves are yellow, the plant wilts at noon, and recovers in the morning and evening, resulting in the death of the tree.

2. Lack of trace elements. The leaves at the top growth point appear yellowish-white, which is caused by iron and zinc deficiency. The yellowing of the new leaves at the top generally occurs when the new leaves are sunny after the shade, the root growth is poor, the weather changes from cold to warm, and the early plant bears too much fruit.

3. Poor plant growth. This situation will not cause the plant to die, mainly because the plant is not growing well, resulting in yellowing in the middle of the middle and lower leaf veins, which is easy to cause premature senescence of the plant. For example, the temperature of the shed is too high, the root system is underdeveloped, the roots are damaged, and the fertilizer and water are not scientific.

Methods for the prevention and control of yellowing of carob leaves.

1. Carob root rot can be irrigated with pesticides. Choice of potion: carbendazim. Formeidi (allicin) + oxafen + copper pine acid root irrigation.

2. Foliar spray can be used in bad weather and in the middle and late stages of plant growth: Bika amino acid foliar fertilizer (chelating various trace elements such as boron, calcium, magnesium, iron, zinc), which can effectively alleviate the yellowish-white color of the top new leaves.

3. Enhance plant resistance, cultivate strong root system of plants, and use fertilizer reasonably to prevent yellowing in the middle of the leaf veins, resulting in premature leaf aging.

<> apply more farm fertilizer and improve soil structure; Balanced formula fertilization, supplementation of trace elements (zinc, iron, sulfur, calcium, etc.); Forbidden gods harvest wheat stubble in spring and protect soil structure; When yellow leaf disease occurs, it can be sprayed with micro-fertilizer, spraying zinc sulfate 2 taels per mu, and preparing a bag of fungicide to protect it; Plant regulator Sandayling or Green Wind 95, Hui Manfeng (choose one), edible brown sugar 2 taels, three days after spraying to turn green, restore mindfulness and blind companionship.

Yellow leaves often occur in the process of bean cultivation, and if not prevented in time, there is a high possibility of yield reduction and harvest failure. This is mainly caused by carob root rot or insufficient trace elements. **Dimethoate emulsifiable concentrate or cypermethrin for carob yellow leaf virus can be sprayed on a sunny day after the dew dries in the morning or before setting in the afternoon.

Symptoms of carob yellow leaf disease.

The main symptom of carob yellow leaf disease is that the bottom leaves turn yellow, fall off easily, and have a tendency to gradually expand upward, which can lead to dead trees in severe cases. The new leaves at the top of the beans turn yellow, often accompanied by the occurrence of fallen flowers, and the pulse of the bean leaves turns yellow in the middle, affecting the yield and quality of the beans.

Carob yellow leaf disease hazards.

Yellow leaves often occur in the process of bean cultivation, and if not prevented in time, there is a high possibility of yield reduction and harvest failure.

Causes of carob yellow leaf disease.

1. Carob root rot: Commonly known as red root disease, this is a soil-borne disease, the early pathogenic bacteria infect the root system, the plant is malnourished, the bottom leaves are yellow, the plant withers at noon, recovers in the morning and evening, and dies.

2. Lack of trace elements: The leaves of the upper growth point of the bean are yellowish-white, and lack of iron and zinc. The new leaves at the top turn yellow, sunny after the shade, poor root growth, cold and warm weather, excessive plant fruiting in the early stage, etc.

3. Poor plant growth: This condition does not cause the beans to die, mainly because the plant grows poorly, and the middle of the middle and lower leaf veins turns yellow, causing premature senescence of the plant. For example, a similar situation may occur when the temperature of the shed is too high, the root system is underdeveloped, the roots are damaged, and the fertilizer is unscientific.

What medicine is used for carob yellow leaf disease.

Carob yellow leaf disease can be **, carob yellow leaf disease can be sprayed with micro-fertilizer, spray zinc sulfate bags per mu. The plant regulator Sandayling or Green Wind 95 and Huimanfeng have good effects.

**Carob yellow leaf virus specific drug.

**Dimethoate EC or cypermethrin for carob yellow leaf virus should be sprayed on a sunny day in the morning after the dew dries or before setting in the afternoon.

Methods for the prevention and control of carob yellow leaf disease.

Yellow leaves of carob caused by root rot need to be disinfected and sterilized in the soil, and the roots should be irrigated with carbendazim.

Beans are one of the common vegetables in people's lives, but they may suffer from diseases during the cultivation process. One of the most common is carob yellow leaf disease, which has a great impact on the growth and yield of carob. Therefore, the prevention and control of carob yellow leaf disease is particularly important.

At present, there are some special drugs on the market for the prevention and control of carob digital source yellow leaf disease to help us effectively prevent and control this disease.

These special drugs include: phenol potato companion oxycarboxyl, dimerazim, carbendazim, etc., which have very good control effects. Specifically, they are able to control the disease by killing the yellow leaf disease fungus of carob.

In addition, these special drugs also have a certain preventive effect, and can be used before the disease occurs to prevent the occurrence of disease. If the disease has already occurred, the specific drug can effectively control the disease, reduce the mortality rate of the bean and reduce the impact of the disease on the yield of the bean.

Therefore, friends who plant beans should pay close attention to the growth of beans during the planting process, and take timely measures to prevent and control the symptoms of yellow leaf disease once they are found to have yellow leaf disease symptoms. The special medicine is a very good prevention and control tool, which can help us easily deal with the yellow leaf disease of carob and protect the growth and yield of carob. However, when using specific drugs, we should also pay attention to the correct use and dosage of drugs to avoid adverse effects on the environment and health.
