What is the matter with the seedlings of flower life and death, a special medicine for the treatment

Flower seedlings are mainly caused by root rot, stem rot and bacterial wilt, and the prevention and control of root rot and stem rot can be used with 96% Tianda Chlormycolin 3000 times + 2116 600 times a day foliar spray or root irrigation, once in 5-7 days, 2-3 times in a row. The prevention and control of peanut bacterial wilt can be sprayed with 72% agricultural streptomycin sulfate 4000 times + 2116 600 times a day, which can basically solve this problem.

Peanuts are the main cash crops in our province. In heavy stubble fields, it is more common to flower and live seedlings. In recent years, after the use of imported Shile seed dressing, it can effectively prevent and control the root rot and stem rot that cause the birth and death of flowers, and the peanut seedlings emerge quickly, and the seedlings are full and strong.

However, a small number of farmers reported that there are still some dead seedlings after using Shile time to mix seeds, what is going on?

Insufficient dosage of Shile Generally, 10 ml of Peanuts should be mixed with 10 kg of Peanuts in Shile, but the dose should be increased in severely ill fields, and 5 kg of peanuts should be mixed with 10 ml of Shile to be controlled. Peanuts are harmful to pesticides, damage the roots, and can easily cause dead seedlings in rainy and low-lying areas, and the same is true for soybean fields. The imported 96 "Jindur", 100 ml mixed with 5 buckets of water to beat 2 acres of land, does not hurt the seedlings, is very safe for peanuts, and the effective period is 30 days longer than acetochlor.

The amount of bacteria in the soil is large Peanuts are mostly planted in heavy stubble, and the amount of bacteria in the soil in local areas is large, so it is not enough to only carry out seed treatment, but also to disinfect the soil. After the peanut is sown and before the seedlings, spray with 10 ml of Shile with 15 kg of water, which can be mixed with Jindur.

The quality of seeds is not high Most of the peasant households keep their own seeds, and the quality is poor; in addition to introducing high-yield and high-quality varieties, it is also necessary to do a good job in drying seeds. Drying seeds in the shell for 3 to 5 days can kill most of the pathogenic bacteria attached to the surface of the peanut shell and greatly reduce the occurrence of dead seedlings.

1. Fludioxonil: mainly for the prevention and control of stem base rot, blight, root rot and sclerotinia disease. For prevention, spray 25g L fludioxonil suspension 750-1000 times at the seedling stage of crops, and if the crop has been diseased, use 1000-1500 times of fine nail fludioxonil to rinse the roots.

2. Chlormycofen: mainly for the prevention and control of root rot, blight, cataplexy and blight. For prevention, spray 1500 times of 30% Oxathyl water agent at the seedling stage, and if the crop has been diseased, spray 1000-1500 times of 30% Methyl Frost and Oxazalin water solution or drench roots.

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.

The special medicine that can be used for the rotten roots of flowers and seedlings is carbendazim, which has a strong effect of disinfection and sterilization. During the maintenance period, peanuts suffer from root rot, stem rot or improper maintenance, which will cause their roots to rot and seedlings to die. In the early stage of the disease, peanuts can be sprayed with carbendazim, which can effectively inhibit the disease and is conducive to the later recovery of peanuts.

During the maintenance period of peanuts, there is a phenomenon of dead seedlings and rotten roots, which may be root rot. If it is caused by root rot, the partially rotten peanut needs to be pruned and then sprayed with carbendazim. If the root system is completely rotten, it needs to be cleaned and the soil sterilized and disinfected, and the seeds can be replanted.

Peanuts have dead seedlings and rotten roots, which may also be stem rot. During the maintenance period, after the peanut has stem rot, it is necessary to properly prune the rotten stem of the peanut in the early stage, and then spray it with chlorothalonil or carbendazim. After spraying 1 time in 7 10 days and spraying 2 3 times in a row, it can effectively inhibit stem rot.

The phenomenon of dead seedlings and rotten roots of peanuts is mainly caused by improper maintenance. During the maintenance period, unreasonable watering and fertilization can easily cause the root system of peanuts to rot. If there is too much water and fertilizer, it needs to be drained or watered in time to dilute the fertility, and it should be maintained in a cool and ventilated position, and the water and fertilizer should be controlled during the maintenance period.

If there is too much water and fertilizer, the rotten roots of peanuts are more serious and can be replanted. If the root system of the peanut is not completely damaged, the peanut can be removed from the land. Wash the peanuts, properly prune the rotten roots and leaves of the peanuts and disinfect them with carbendazim, and then plant them in a new soil that is loose and breathable.

1. Peanut diseases and insect pests, normal metabolism is blocked, resulting in the death of flowers and seedlings. Consult a professional for advice and spray with the right insecticide.

2. The peanut has not been watered for a long time, and the water in the plant is insufficient, resulting in the situation of dead seedlings. Water the peanuts regularly and quantitatively to replenish the water in time.

3. The temperature of the sideside bright reed in the surrounding environment of the peanut transport belt changes greatly, which does not conform to its growth habit, resulting in dead seedlings. According to the growth habit of peanuts, choose the appropriate planting environment.

4. Peanuts are malnourished and have poor development, resulting in the birth and death of flowers. Fertilizer should be applied regularly to ensure the healthy growth of the plant.

4. Peanut malnutrition and poor development status lead to blind flowers and no seedlings. Fertilizer should be applied regularly to ensure the healthy growth of the plant.

Flower life and death seedlings are generally caused by the following reasons.

Seed quality issues.

The use of old seeds or moldy seeds greatly reduces the germination vitality, and it is easy to have lack of seedlings, broken ridges, rotten seeds, dead seedlings and other phenomena.

2.Sowing too early or too deep. Early sowing, low ground temperature, reduced seed enzyme activity, weakened respiration, slow emergence of flower buds, prolonged soil retention time after deep sowing, reduced seed disease resistance, increased probability of seed disease, and easy to die seedlings and rot roots.

The phenomenon of seedling shortage in early-sown and deep-sown fields is more serious than that in late-sown and shallow-sown fields.

3.Severe continuous cropping. A large number of pests and diseases have accumulated in the soil of peanut continuous cropping, and serious conditions often occur in plots that do not use fungicides or pesticides when sowing, which is another major cause of dead seedlings and root rot.

4.Improper use of chemicals and fertilizers. Chemical fertilizers, immature fertilizers, chemical pesticides, etc., which are in direct contact with seeds or used in large quantities, can easily cause seeds to burn and rot; Excessive use of herbicides or uneven spraying of dust leads to excessive local doses, resulting in the death of seedlings.

5.Calcium deficiency. Insufficient calcium nutrition in the soil hinders the growth and development of peanuts, resulting in dead seedlings. Fertile leaf calcium fertilizer can be supplemented in time to replenish nutrients for the soil.

6.Pest and disease damage.

Peanut continuous cropping, soil and peanut residue with bacteria, resulting in stunted plant growth and development, resulting in dead seedlings, dead trees to rise to Tongbi. The main diseases are leaf spot, root rot, stem rot, etc.; The main insect pests are grubs, needleworms, mole crickets, etc.

I am a rural person in Guangxi, this is not the main peanut producing area, our peanuts are only a few points, mainly for their own consumption, oil extraction, stir-fry vegetables to wine, year after year, summed up a lot of experience, the life and death of flower seedlings, the following to share the experience of local farmers, I hope to help you. The main reason for flower planting is that the land is used to plant peanuts, and the continuous cropping of peanuts leads to more and more viruses and bacteria in the soil, and when encountering virus germs, it will breed when the weather is suitable, and if it is not treated in time, it may lead to the life and death of a piece of flower seedlings, loss, which is mainly caused by the peanut stem rot and root rot caused by virus and bacteria.

In addition to the influence of peanut virus pathogens, seed quality, sowing depth will also be affected, according to experience, peanuts are suitable for relatively late shallow seeds, for the earlier deep seeds of old slippery orange peanuts, more susceptible to infection with pathogens, and for the quality of the seeds, moldy seeds, damaged seeds will lead to dead seedlings, low germination rate and other problems. The best preventive measure for stem rot and root rot is land rotation, and it is best to change to other crops for two consecutive years, in our case, it is two years of peanuts, and in the market it is decided to be soybeans, sweet potatoes and other crops, crop rotation, which can minimize the impact of viruses in the soil.

For the main peanut producing areas, under limited crop rotation conditions, combined drugs are required for control, and carbendazim is generally dressed before sowing. Soak peanut seeds in water, and then use carbendazim wettable powder for seed dressing, in order to make the powder evenly mixed in the seeds, you can refer to the 50% carbendazim wettable powder of the weight of peanut seeds for seed dressing, and the carbendazim seed dressing method can effectively prevent root rot and stem rot.

Flower seedling is the best way to prevent life and death, when the preventive measures fail, peanut root rot, stem with rot in advance, at this time growers must be timely medication, can consider the use of 50% carbendazim wettable powder 800 times liquid or 70% methyl tobuzine wettable powder 1000 times liquid, medication is for reference only.
