What is the reason for the yellowing and death of peanuts after emergence?

The main reasons for the yellowing of peanut leaves at the seedling stage are as follows:

1. Drought. The leaves are dehydrated and the leaves will turn yellow.

2. Underground pests. Eating peanut rhizomes leads to obstruction of nutrient delivery.

3. Herbicide damage.

4. Lack of nutrients. The above reasons may cause the leaves of peanuts to turn yellow and die in severe cases.

In response to these situations, it is enough to solve them one by one. Or if you want to save more trouble, you can also increase the yield of high-yield peanuts**. Skills to supplement a large number of trace elements, but also to remove pesticide damage, resistance to diseases and pests. To achieve the purpose of increasing production.

It may be yellow leaf disease, or it may be that peanuts are planted a little early. Consult, the old farmer born in China. Listen to their opinions. You can also go to pesticides and fertilizers. After-sales after-sales ask.

Is it too much base fertilizer? Burned the roots. So the shipment slowly withered.

Increase light, dilute fertilizers, replenish elements, control pests, and more.

1. Peanut seedlings are not tolerant to strong direct light, but they also need light during the growth process, otherwise it will cause chlorophyll to be difficult to form, so that the leaves will turn yellow, and the plants can be maintained in a bright and astigmatistic place. Peanut seedlings need to rely on fertilization to maintain normal growth, but excessive or too concentrated fertilizer may cause fertilizer damage and cause yellowing of leaves, so it is necessary to water a large amount of water immediately to dilute the fertilizer.

2. The demand for water of peanuts in the seedling period is still relatively high, and it is necessary to keep the substrate in a slightly moist state. It may also be caused by improper fertilization, too much fertilization or lack of nutrients will cause the leaves to turn yellow, too much fertilizer and more watering, and insufficient nutrients to fertilize more.

3. When peanuts are deficient in iron, there will be yellowing of leaves, peanuts are only the upper part of the leaves are yellow, and the lower part of the leaves are still green, and the veins of peanut leaves will also be yellowed when it is serious, and the size of the leaves of peanuts has not changed, but the color has changed. Therefore, if there are yellow leaves in the peanut field, you can see if there is a characteristic of iron deficiency, and if so, you can carry out iron supplementation to rescue it.

Excessive dosage of herbicide, or improper use, will produce adverse reactions, resulting in yellowing of leaves, judgment willingness is also very good, after a few days of herbicide, found that the leaves are wilted, basically herbicide damage, according to the degree of damage to remedy, can alleviate the spraying of lidomicin and foliar fertilizer, if the adverse reaction is serious, basically no help.

<> peanut root rot, such as root rot, stem rot and other root rot, combined with the first two conditions, peanut seedlings appear yellowing and even die. Does this situation require a good partner? (6% fipronil, fine beetle, thiofur seed treatment suspension) or whole milk?

Peanut package spraying can effectively prevent and control root diseases at the seedling stage, supplement nutrients, promote the development of the first two pairs of side branches, and promote flowering.

Water problem, that is, precipitation problem, in two extreme cases, drought in some areas needs to be watered, and some areas are waterlogged and need emergency drainage, in this case, the soil is too dry or under water for a long time, the peanut leaves are likely to appear yellowing, when encountering moisture, there is no good irrigation and drainage method, according to the specific situation. In addition, it is recommended to apply foliar fertilizer after irrigation and drainage to promote recovery. The phenomenon of yellowing leaves, and the small plant, in fact, can not keep up with the nutrition, resulting in yellow-green leaves, therefore, it is also in the actual planting process, it is more common, so this time, it will be timely top dressing urea, and at the same time, you can also add phosphate fertilizer, potassium fertilizer, and some trace elements, which can be added to the leaves for spraying.

Do a detailed explanation of the problem for a detailed interpretation of the problem, I hope it will help you, if you have any questions, you can leave me a message in the comment area, you can comment with me a lot, if there is something wrong, you can also interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you. That's all for sharing, if you like me, please follow me. If you guys have any ideas, you can let us know in the comments below.

1. Mold pollution: Peanut is a kind of seed food rich in oil, with good nutrients, which is easy to breed Aspergillus flavus, which will breed yellow flora, causing peanut sprouts to turn yellow and rot. This kind of yellowed peanut sprouts cannot be eaten, because aflatoxin is a highly toxic substance, and eating it can lead to poisoning, serious and even death; In addition, it also has teratogenic effects, and pregnant women are extremely harmful to their babies when they eat it.

2. Oxidation and yellowing: peanuts are rich in oil components, if not cultivated properly, the activity of peanut sprouts is very low, and will not grow normally, but rich water, suitable temperature, and highly active peroxidases will lead to oxidation of the oil components in peanut sprouts, and there is a possibility that peanut sprouts will turn yellow. In this case, yellowed peanut sprouts are not recommended to be eaten, because peanut sprouts are prone to spoilage during the process of oxidation and yellowing.

3. Peanut sprout infection: Although peanut sprouts have not officially grown into large peanuts, they will also be used for peanut poor quality and infection with some peanut diseases. Such as root rot, is due to the fungus caused by the peanut bud infection, yellowing, rot, this kind of yellow peanut sprouts are not recommended to eat, taste, nutritional value are affected by nutrition.

It may be caused by a long period of rainy weather, or it may be caused by a lack of moisture.

The climate is not suitable, the temperature is relatively cold, the soil is not fertile, I did not water in time, did not fertilize, did not get enough nutrients, and inhibited growth.

Summary. Hello! There are the following reasons:1Sowing too deep, weak seedlings yellow, so pay attention to the sowing depth, 3c5 cm. The soil around the flowering tree is peeled to expose the cotyledons, and the sunlight photosynthesizes to accelerate the conversion of chlorophyll and promote the differentiation of flower buds.

How to treat peanut seedlings that are yellow and not long? What kind of medicine is used?

Hello! There are the following reasons:1

Sowing too deep, seedlings are weak and yellow, so pay attention to the depth of sowing, 3c5 cm. The soil around the flowering tree is peeled to expose the cotyledons, and the sunlight photosynthesizes to accelerate the conversion of chlorophyll and promote the differentiation of flower buds.

2.The dosage of blocking medicine is too large, and the blocking drugs such as acetochlor are sown in peanuts 2c3, and the rain is encountered after the cong dress, and the peanut seedlings are affected to some extent, and the peanut stems and leaves are twisted and the leaf edge is yellowed. Rent this requires foliar sprays of brassinin and Fengqia Duobao nutrient repair, and it will come over in a few days.

3. Peanut root system problems are troubled, similar to root rot and stem rot and other root diseases, which occur together with the first two points, and the phenomenon of yellowing and even death of peanuts at the seedling stage occurs in Tong Cong. This situation requires timely disease control.

4. There is no fertilization in the early stage, the wheat set peanut is planted with peanuts and topdressing in the later stage, the soil fertility efficiency is insufficient, the seedling stage can not absorb nutrients, and the seedlings are yellow. At this time, it is best to supplement the liquid nitrogen with the first foliar spray, which has a high utilization rate, fast repair and low cost. Some people immediately thought of using urea, which must have water to cover the soil, but it takes time to turn and merge before the crops can be harvested.

Peanut seedlings slowly wither and die, and after the seedlings are pulled up, there is black mold in the roots, and some of the seedlings turn yellow.

What a good thing you can do, dear. <>

It may be due to the following reasons:1The soil is too wet:

Peanut seedlings are sensitive to soil that is too wet, and the roots are prone to black mold, which leads to the death of seedlings. 2.Soil hypoxia:

The root system of peanut seedlings needs enough oxygen to grow, and if the soil is deprived of oxygen, the roots are vulnerable to damage and cause wilting. 3.Overwatering:

If the ground is too wet, it is easy to cause damage to the roots of peanut seedlings, which in turn leads to plant death. 4.Pests and diseases:

Peanut seedlings are susceptible to fungi and insect infestations, which can cause plant wilting. 5.Climate Change:

When the weather is dry and hot, peanut seedlings can easily wilt, especially when there is a lack of water. You can avoid peanut seedlings wilting by taking the following measures:1

Control the amount of watering to avoid over-wetting the soil. 2.Make sure the soil is well permeable to avoid hypoxia in the soil.

3.Pay attention to pest control and regularly check the condition of peanut seedlings. 4.

Choose varieties that are suitable for the local climate and avoid growing peanut seedlings when it is too hot or when there is a lack of water. 5.Fertilize regularly to provide adequate nutrients for peanut seedlings.

Summary. Hello dear! The reasons why peanuts die after they emerge are as follows:

1.Dehydration: Dehydration is one of the most common causes of peanut emergent death.

If the soil is too dry, the peanuts will not be able to absorb enough water. 2.Overwatering:

Although peanuts need plenty of water to grow, if the soil is too wet, the roots are prone to drowning. 3.Malnutrition:

If the soil lacks the necessary nutrients, peanuts cannot get enough nutrients, which affects growth and development. 4.Diseases and insect pests:

Germs and bugs can attack peanuts and cause death after emergence, especially in humid environments. 5.Insufficient light:

Peanuts need enough light for photosynthesis, and if there is not enough light, it will lead to problems such as slow plant growth and yellowing of leaves. In order to prevent the death of peanuts after emergence, it is recommended that you choose the soil and fertilizer, and control the water and light conditions. At the same time, it should be regularly checked for the presence of diseases and pests, and timely measures should be taken.

What kind of medicine is used to prevent and control it?

Kissing, flower seedlings can be controlled with agents such as carbendazim, difenoconazole, and xunmycolin. Treat the seeds of peanuts with some pesticides, or add pesticides to the sprayer when the peanuts are unearthed, and the time of spraying must be controlled after 7 p.m.
