What s the deal with the soil borne disease of ginger? Are there any precautions?

Ginger disease is usually transmitted from the soil, so it is important to disinfect the soil. Disease infections in ginger can be minimized when diseases in the soil are suppressed to a minimum or eliminated. However, it should be noted that while eliminating diseases in the soil, it will also destroy some beneficial bacteria in the soil, making the soil nutrient imbalance.

Therefore, before planting ginger, we need to do the following three operations on the soil.

1.Disinfect the seriously ill land first.

The land is also divided into two conditions: serious illness and no disease. For disease-free or mildly diseased land, there is generally no need for disinfection, and ginger can be planted directly. However, for some severely diseased land, disinfection is a must.

The general disinfection method is to disinfect with medicine, with a disinfectant called Vebaimu. After the land is disinfected, it usually takes 10 and a half days to dry it so that the disinfectant disperses before planting. If conditions permit, high-temperature flame disinfection can be used, which is a safe and green way to disinfect the soil.

2.Restore beneficial microorganisms in the soil, i.e. beneficial bacteria.

When we disinfect the soil, the disinfectant destroys the beneficial bacteria in the soil to a greater or lesser extent, resulting in a decrease in soil fertility and an imbalance of nutrients. Changes in the microbial environment in the soil can lead to a decrease in ginger resistance planted in the soil. Therefore, after soil disinfection, it is necessary to apply organic compound fertilizers, some trace element fertilizers and beneficial bacteria fertilizers to the soil to improve soil fertility, and then plant ginger.

At each stage of ginger growth, we also need to properly adjust the ratio of various fertilizers.

3.Slowly improve the microbial environment in the soil.

Planting crops pays attention to a balanced growth environment, so in the process of ginger growth, properly adjust the fertilizer and water conditions, and try to avoid continuous cropping. At the same time, use farmhouse fertilizer as much as possible to slowly improve the growth environment of microorganisms in the soil. Ginger is a very soil-dependent crop, and soil-borne diseases in the soil are very harmful to ginger.

Therefore, the above three points must be done to minimize the harm of soil-borne diseases to ginger, so as to increase the yield of ginger.

The common soil-borne diseases of ginger are: 1. root rot, leaves and stems turn yellow and die, and the root system rots. 2. Ginger blast, the internal tissues of the diseased ginger are softened and rotted, and the squeezing of the diseased part exudes dirty white juice, 3. Stem rot, watery lesions appear at the base of the stem, and the leaves are yellow.

To prevent these soil-borne diseases, it is necessary to completely remove the sick and residual bodies in autumn and winter. Second, choose plots with high terrain and good drainage for planting, and the base fertilizer is mainly rotted organic fertilizer.

Fourth, clean the ditch and drain the stain in time, reduce the humidity in the field, and avoid using rice stalks as ginger mulch. 5. Apply sufficient nitrogen fertilizer, increase phosphorus fertilizer, potassium fertilizer and organic fertilizer.

Ginger spitting disease actually means that there is a special preventive measure for the formation of this bacterium, and it is best to spray some pesticides, and you should pay attention to turning the soil frequently, so that you can.

The soil-borne disease of ginger is an extremely dangerous disease. There are many reasons why this disease can be harmful. For example, the use of large amounts of chemical fertilizers in the planting process can lead to an imbalance in proportion.

There are a lot of precautions like this, such as, um, be sure to be balanced in terms of fertilization, then use less pesticides, and then add more organic fertilizer.

Symptoms of stem base rot appear: it is called rotten neck disease. The stems and leaves turn yellow from the lower part of the ginger stem and the leaf margin, and then spread to the whole ginger, after which the ginger plant dies.

2. Decay rots from the outside to the inside. 3. The symptoms of ginger stem base rot with water stains on the stem of ginger straw: The ginger block infected by the disease is water-stained, yellow-brown, and gradually softened and rotted inside. Rotting is controlled by agriculturally expanding from the inside out, at the base of the ginger stem.

Choose disease-free ginger species. At the time of sowing, the ginger seeds should be sterilized, and the cut ginger should be soaked in 50% carbendazim 800 times wettable powder solution for 5 8 hours, or with neophytomycin 2000 times solution for 24 hours. Choose ginger ground and sterilize.

Crop rotation. Heavy stubble planting for many years is one of the main reasons for the serious occurrence of stem base rot, which will lead to the accumulation of bacterial sources in the field for many years, and the pathogens will infect and develop once they encounter suitable climatic conditions. Ginger can be used with grasses for 2-3 years, first of all, soil disinfection treatment.

Disinfecting the soil before planting with chloropicro and Vibemu can effectively kill the harmful bacteria in the soil, and also kill the beneficial bacteria, so the beneficial bacteria must be supplemented after treatment. Before ploughing the land, the topsoil with gray mold and sclerotinia and sclerotinia disease plants and their residues and even diseased plants left over from the previous stubble in the cultivation soil should be thoroughly cleared out of the field and treated intensively. About 4kg of 80% carbendazim per mu is mixed with fine soil, evenly sprinkled into the cultivation soil, and evenly mixed with the soil.

Soil treatment: ginger is a crop that is easy to replant, and the phenomenon of self-toxicity is obvious, so the soil treatment before planting ginger is very important, you can apply lime nitrogen, cotton and other soil fungicides to disinfect the soil, and irrigate a large amount of water before planting. Invented the patented product of biogramame, which is a non-toxic, harmless and non-residue biological agent, which releases beneficial bacteria by killing and antagonizing the pathogenic bacteria of stem base rot, and the effect is obvious, and it can be the ginger that has suffered from stem base rot disease.

Must be deep ploughing: the impact of rain disasters has led to more and more problems in ginger fields, and deep ploughing can play a good role in controlling and sterilizing some fungal soil-borne diseases. In order to reduce the harm of insects and diseases, the use of raw manure in ginger plots is eliminated.

Smoke the soil carefully, and it is more important to protect the beneficial bacteria in the soil. Smoking is the way we treat the soil when we have to do it, not our solution.

First, crop rotation: ginger blast is a soil-borne disease, the fungus can survive in the soil for more than 2 years, for the plots that have been diseased, it is recommended to plant ginger at an interval of 3 years, and wheat and corn can be planted in the middle, and it is not recommended to plant tomatoes, peppers and other crops. Second, soil treatment:

It is recommended to use lime nitrogen (calcium cyanamide) for soil treatment, in ginger planting, it is recommended to use 50 kg of lime nitrogen with well-rotted farmhouse organic fertilizer (pig manure, straw, etc.) for one acre, mix and mix, sprinkle to the field and water, be sure to cover it with plastic film for more than 20 days, and then carry out land preparation and sowing.

Personally, I think that if you want to prevent soil-borne diseases before ginger planting, you must treat the pests in the soil at this time and improve the soil in advance.

Soil disinfection should be carried out after 2-3 years of crop rotation, and of course disinfection will also eliminate beneficial bacteria, so nutrients should be supplemented after that.

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.

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.

Ginger diseases mainly include spoilage disease (commonly known as ginger blast) and leaf blight, and insect pests mainly include corn borer and curved beetle, which should be sprayed in time to kill and prevent. Ginger blast generally starts in June, high temperature and rain are serious, this disease mainly adopts comprehensive agricultural control, such as crop rotation and stubble, strict seed selection, etc. The diseased plants were found in the field and removed in time, and the healthy plants within the meters around the diseased plants were removed, the infected soil was dug up, 1 kg of lime was sprinkled in and around the diseased holes, and the roots were irrigated with 50% carbendazim 500 times or 72% agricultural streptomycin sulfate soluble powder 3000-4000 times, or 50% dyceymonium 800 times or 50% DT wettable powder 500 times + new high-fat film spraying to prevent the disease from continuing to occur.

Leaf blight leaves turn yellow at the initial stage, and the yellow part gradually turns brown and dies. It extends from local to the whole leaf vein, showing brown to reddish-brown leaf margin lesions, with wavy edges and dark color. The prevention and control method is to spray 25% carbendazim wettable powder 600 800 times liquid on ginger seedlings in the early stage of the disease, or 1:

2: 200 times Bordeaux solution, or 600 times 70% zebsen zinc, depending on the condition, every 15 to 20 days, spray 2 3 times. If an appropriate amount of new high-lipid film is added to the spraying solution, the effect of pest control is better.
