In the process of planting ginger, there will be pests and diseases, how to prevent ginger rot disea

When it comes to the stage of terminal illness, it is still necessary to use green bag fertilizer with strong antiseptics. Specific usage: Apply green bag fertilizer and water to dilute 50 times, spray irrigation.

It does not contain any toxic substances and has the effect of insecticidal fertile soil. Diseases are most likely to appear in a more humid and warm environment, so the ventilation management in the field should be strengthened when planting, and try to avoid ginger plants being in a cool and stuffy environment.

It is necessary to use agricultural streptomycin plus mesomycin or copper-containing preparations, such as killable, stirring the potion, irrigating the roots, and do not spray foliar, otherwise there is no effect. If it is severe, it will be once every 3 days, and if it is not severe, it will be once every 5 days. The suitable temperature for the growth of ginger is 22-28 during the day, 15---18 at night, the temperature is getting higher and higher after the beginning of summer, and the temperature in the small arch shed is as high as 35 or more, which is very easy to burn the seedlings, especially after watering, the surface is very easy to form a higher water vapor, burn the stem base, and strictly select the mother seed before sowing 2

Soil disinfection, killing pathogenic bacteria in the soil3Before germination, sterilization with chemicals, top seedlings new spray ditch ** spray ditch 4If there is a rotten neck, first isolated, watered bypass, sprayed, and sprayed.

For general medicine, copper preparations are better, copper hydroxide with Bordeaux liquid, carbendazim, methyl tobuzin, can be mixed with water to pour the sick nest, and then cover it with plastic film. Choose ginger that is free of diseases and insects and mold to prevent the spread of diseases and insects. 2.

The soil is sterilized and disinfected. 3.Cultivating strong seedlings.

Seedlings are the primary link of ginger yield, only strong young shoots can grow long seedlings, lay a good foundation for the vigorous growth of plants, and achieve the purpose of high yield.

Select ginger seeds to avoid ginger germs: choose ginger seeds with strong and disease-free plants, and ensure that the ginger pieces are harvested and stored in the cellar without disease spots. Before the process of drying ginger and trapping ginger and germination, it is necessary to strictly select the seeds. Choose ginger cubes for hypertrophy.

Some pesticides should be sprayed to prevent pests and diseases, and they should be watered frequently, weeds should be removed, and the temperature should also be raised, and the light should be increased, etc., so that ginger rot can be controlled.

When planting ginger, it is necessary to choose excellent ginger varieties, do not have rot disease, and put some quicklime on the soil.

The planting environment of ginger should be selected in a dry and ventilated field, before planting, it is necessary to apply grass ash and organic fertilizer in the ground, and then plant ginger after soaking it with disinfectant.

Be sure to spray the corresponding pesticides in time, no matter what kind of pests and diseases are very afraid of the drugs that deal with it.

Summary. The prevention and control of rot disease should take comprehensive preventive measures from all aspects of cultivation and management, and fundamentally prevent the occurrence of ginger rot disease, and the main preventive measures are as follows.

First, the strict selection of disease-free ginger: in early October, the condition of ginger field has been basically stable, can be strictly selected in the disease-free ginger field, the selection of robust and disease-free plants to keep the seeds, should be a single collection and storage, the second year before germination should be strictly selected, in order to prevent the spread of diseased ginger.

2. Soaking and disinfection: After disinfection with potion solution before germination, wash the ginger with water, remove it and dry it to promote germination.

3. Land selection and land preparation: It is necessary to choose a plot with high terrain and good drainage, and make a ginger ditch for land preparation, so as to facilitate drainage and irrigation and prevent diseases caused by water accumulation in the field.

Fourth, water purification irrigation: irrigation is best carried out in a single ditch or a single field, not flooded irrigation to prevent the spread of disease infection, if conditions can be used pipeline irrigation.

In the process of planting ginger, there will be pests and diseases, how to prevent ginger rot disease?

The prevention and control of rot disease should take comprehensive preventive measures from all aspects of cultivation and management, and fundamentally prevent the occurrence of ginger rot disease, and the main preventive measures are as follows. First, the strict selection of disease-free cover of the seed ginger: in early October, the condition of the ginger field has been basically stable, can be strictly selected in the disease-free ginger field, the selection of robust and disease-free plants to keep the seeds, the forest should be single receipt and storage, the second year before germination should be strictly selected, in order to prevent the spread of disease with ginger.

2. Soaking and disinfection: After disinfection with potion solution before germination, wash the ginger with water, remove it and dry it to promote germination. 3. Land selection and land preparation:

It is necessary to choose a place with high terrain and good drainage, and make a ginger ditch on the land, so as to facilitate drainage and irrigation and prevent diseases caused by water accumulation in the field. Fourth, water purification irrigation: irrigation is best carried out in a single ditch or a single field, not flooded irrigation to prevent the spread of disease infection, if conditions can be used pipeline irrigation.

Fifth, the application of net fertilizer: can not apply diseased plants or call is the disease * made of farm fertilizer, the application of farm fertilizer must be fully sensitive to the chain of friends. 6. Timely removal of diseased plants

If diseased plants are found in the field, they should be eradicated in time, and adjacent disease-free plants should be eradicated, and diseased soil should be dug up, and lime should be sprinkled in the diseased holes, and then filled with clean and diseaseless plants. to control the spread of disease. Seventh, the implementation of crop rotation and stubble:

The first stubble of ginger planting is best to choose a new vegetable field or a plot for planting food crops, and the vegetable field is best to be onion and garlic stubble, implement crop rotation, and use disease-free ginger acacia, coupled with fine management, has a significant effect on controlling the occurrence of ginger rot disease.

In the process of growth, ginger will be invaded by a variety of pests and diseases, which will seriously endanger the production, sales and quality of ginger and reduce the profitability of growers.

GingerPestilence

Ginger blast is one of the main diseases of ginger, ginger will generally limit the yield of 20%-30% after infection, and 80% in severe cases, which is hugely harmful. The key to this disease is to damage the underground stems of ginger, and when the disease occurs, the lesions become brown and dull, and the internal organs gradually rot, and the best plants wither due to the loss of absorption.

Prevention and control methods: The cause of this disease is mainly caused by the infiltration of pathogenic bacteria, so it is necessary to disinfect the ginger and soil when planting, solve the germs, irrigate with clean water, and use zero-pollution chemical fertilizers. If the diseased plant is found to be immediately pulled out of the field and damaged, and the diseased hole is disinfected.

Rot diseaseWhen the rot disease occurs, the leaves of ginger will turn yellow, gradually shrink and wither, and eventually cause the whole plant to wither, and the rhizome will become loose after the plant is infected until it rots, and there is also a foul smell.

Prevention and control methods: The germs of this disease are mainly based on the inflamed plants of ginger wounds, so special attention should be paid not to cause damage to the surface of ginger when planting, and spraying drugs to carry out prevention and control at the time of onset.

Pigmentation

The key damage to the leaves of the color spot disease, the leaf of the disease occurs fusiform or long annular lesions, the edge of the lesion is dark brown, the middle reddish-brown, very easy to break, to the middle and late stage of the disease, the lesion occurs a large number of black spots, in the more serious condition, the leaf is covered with a lot of lesions. Its pathogenic pathogen is ginger leaf spotted mold, which is infectious, can be spread through wind and rain, and has a high incidence in warm and humid, lush forests, and high environmental humidity in the field.

Prevention and control methods: effective rotation, avoid heavy stubble, top application of organic fertilizer, improve plant disease resistance, in the early stage of the disease, can be sprayed hydroxytobuzin wettable powder, mancozeb wettable powder and other drugs for prevention.

Ginger borer

Ginger borer is also called borerworm, it is mainly harmed by juveniles, which eat on ginger seedlings, causing the leaves of the plant to turn yellow, and the plant withers when it is serious.

Control methods: hunt nymphs to prevent them from reproducing rapidly, in the juvenile stage, you can use pyrethroid pesticides to spray poison, and sprinkle them on the heart leaves of seedlings, the effect is excellent.

Ginger maggots

Ginger maggot is mainly a pest of ginger during the storage period, endangering the production, sales and quality of ginger, and the larvae eat in the ginger and continue to gnaw off, so that the ginger is only the outer skin, and its feces will cause the ginger to rot.

Prevention and control methods: remove the source of insects, find that the damaged ginger is replaced immediately, completely clean the ginger cellar when storing, and poison the ginger maggot with insecticidal double spraying.

Effect of Jinyunfan silicon fertilizer application

The petiole is erect and the nodes are short. Improve soil acidification, agglomeration, avoid falling seedlings and dead trees, and promote the balanced absorption of light fertilizer. Improve the strength of ginger, the ginger shape is correct, and the ginger buds are more hypertrophied.

Good coloring, good taste and shelf life. Increase freshness, improve quality, and increase yield. It can prevent ginger blast, play with diseases, and resist the harm and infection of germs.

1. Put the taken ginger in a warm position for germination, and after the ginger is dewed, cut it into pieces according to the young shoots, and each piece can keep 2 young shoots. Ginger is not waterlogging tolerant and prefers soil with good drainage ability, so you can use soft, breathable, nutrient-rich and well-drained sandy loam soil, and before planting, loosen the soil and apply basal fertilizer a week in advance.

2. During the planting period, control the plant spacing and row spacing, add an appropriate amount of water to the soil pit, and plant ginger blocks in the soil pit. After planting, cover with a layer of fine soil, and with an appropriate amount of watering in the later stage, generally between 20 and 30 days, the plant can emerge. During the maintenance period, the plants need to be weeded to avoid weeds competing for nutrients from the plants, which can affect the growth of the plants.

3. During the maintenance period, it is necessary to water and fertilize the appropriate amount and water the appropriate amount to keep the soil moist. The fertilizer is mainly a compound fertilizer containing nitrogen, phosphorus and potassium, and the appropriate amount of thin fertilizer is applied, and the concentration is too high, which will hurt the root system of the plant. Ginger is afraid of strong light, and during the summer heat, it is necessary to build a shade shelter to prevent the plants from being burned by the scorching sun.

4. Ginger is a perennial herbaceous plant, during the autumn period, collect strong, thick and disease-free ginger rhizomes and store them indoors. In the southern region, the climate is warm, generally between January and April in spring, and the stored ginger can be taken out and planted. In the northern region, the climate is colder, and it is generally suitable for planting around May.

5. Prevention and control of pests and diseases

1) Ginger borer and ginger maggot: trichlorfon and phosphine can be used for foliar spray control.

2) Spot disease: 800 times of 50% chlorothalonil can be sprayed, and sprayed once every 7-10 days.

3) Rot disease: During the peak period of disease from July to September, the diseased plants should be uprooted as soon as possible, and the soil around the plants should be dug up to prevent bacterial infection, and then a small amount of lime should be sprinkled, and then the ground can be filled with soil.

Ginger distemper is one of the main diseases of ginger, ginger sickness is usually reduced by 20% to 30%, and in severe cases, it will be reduced by 80%, and the loss is very large. This disease mainly harms the rhizomes of ginger, and at the onset of the disease there are water-stained spots, and as the disease progresses, the spots become yellowish-brown, lose their luster, and the internal tissues begin to decay, preferably with the loss of absorption capacity of the plant dies. The cause of the disease is mainly caused by pathogen infection, and when planting, ginger and soil should be disinfected, germs should be removed, watered with clean water, and non-polluting fertilizers should be applied.

It is found that the bottle column needs to be removed in time, disappear in the field, disinfect the bottle blood, and during the outbreak of the disease, it can be prevented with root filling sterilizer, root rot, chikpine, and other agents.

Spot disease mainly affects the leaves, and the disease occurs when spindle-shaped or round spots appear on the leaves. The edges of the spots are brown, medium yellowish-white, and they are very easy to perforate, and in the later stages of the disease, many small black spots will appear on the spots, and in severe cases, the leaves are covered with large and small spots. Its pathogenic pathogen is a strong leaf punctate fungus, which is more contagious, spread by wind and rain, warm and humid, and is easy to develop in the environment of stagnation between plants and high humidity in the field.

Reasonable crop rotation, avoid continuous cropping, increase organic fertilizer, improve plant disease resistance, and spray methotrexate humidifying powder, white fungus humidifying powder and other agents for prevention in the early stage of the disease. Ginger insects are also called heart worms, mainly larval injuries, the larvae are eaten by ginger seedlings, so that the leaves of the plant are yellow, and the plant withers and dies in severe cases.

Catch the adults, do not multiply quickly, spray local pesticides with skin in the larval stage, and sprinkle them on the heart leaves of seedlings, the effect is very good. Ginger rot disease is a devastating ill of ginger cultivation. After the occurrence of ginger rot disease, the yield of ginger will decline, and the severe one will also become extinct, which is one of the important reasons limiting the high yield of ginger.

When selecting Kang seeds, choose disease-free fields and disease-free Kang varieties for planting. It can prevent the occurrence of diseases at the source. Pay attention to drainage, control the number of irrigation, organic fertilizer, and timely top dressing.

Ginger planting should strictly implement crop rotation, and it is best not to continue planting ginger every few years.

In the early stage of ginger rot disease, it is prevented with drugs, and the roots, stems and leaves of ginger can be prevented by drainage with uric acid water-soluble powder, and the leaves of ginger that begin to shrink begin to shrink, and the disease of ginger anthracnose is mainly on the leaves of ginger. Ginger has semi-yellowish-white leaves, thinned spots in the middle, and is easily broken or perforated. When it is severe, the military squad is dense, and the anterior lobes are like stars.

Disinfection should be carried out at all times. And then because growing ginger is very difficult to take care of. So be sure to clean up the environment around the ginger. In this way, the ginger will grow very well.
