How to prevent ginger rot How to prevent ginger rot How to prevent ginger rot?

It is recommended to use streptomycin sulfate or agricultural streptomycin 4000 5000 times solution, or 1:2:300 400 Bordeaux solution, spray once every 7 10 days, and control 2 3 times in a row.

If diseased plants and ginger are found, they should be pulled out immediately, and lime should be sprinkled on the diseased hole and its surroundings for disinfection, and the diseased plants and ginger should be treated centrally, not composted.

FYI!

Attention should be paid to the management of mines, and soil with good air permeability should also be provided. Pay attention to the pH level of the soil. Crop rotation is used for management, and pesticides are sprayed regularly. This will prevent DJI from rotting.

Dajiang generally likes dry and cold soil, so we must avoid too wet or too exposed soil, and control the amount of nitrogen fertilizer in the process of fertilization, not too much.

Pay attention to the planting time, prevent pests and diseases in advance, pay attention to disinfection when soaking seeds, use clean water for irrigation, and use some pesticides to prevent.

Pay attention to the sowing time, prevent insect pests in advance, pay attention to elimination when soaking, irrigate pure water, and prevent pesticides.

The most commonly seen diseases are spot disease and rot disease, among which rot disease is more harmful to ginger.

Rot Disease At first, the leaves of ginger will turn yellow, then slowly shrivel and dry up and even curl. The disease is contagious and can infect the whole ginger plant and eventually cause the plant to die. Often, the roots of the plant become soft due to disease, which eventually leads to internal rot.

When this happens, you will smell a sour smell. The germ is able to hibernate at the mouth of the disease and becomes ill when the temperature is right.

The disease is usually treated with a spray and planted to avoid damage to ginger, as the germ is often able to infect the plant through wounds.

Spot disease This disease mainly affects the leaves of ginger, causing perforation of the leaves, which can spread directly when it rains. At the same time, the milder environment will also make the disease grow rapidly. When planting, the soil should be replaced in time to avoid this situation.

We want to make sure that there are no problems with drainage. Appropriate fertilizer application for prevention.

In terms of insect infestation, it is mainly a kind of insect called ginger borer, which can not only eat the young shoots of ginger, but also burrow into the stem to eat the internal plants. To prevent this bug, it can be exterminated with drugs at the initial stage, and the young eggs of the borer can be eliminated at this time to prevent it from multiplying and causing damage. If you find the place where it has been eaten in time, clean it up as soon as possible to prevent transmission.

Due to the obstruction of water and nutrient transportation, the main stem of the ground is dried up and died from top to bottom, and it is wilted, the root is cut to check the browning of the underground tuber, the root system is not developed, some are soft and rotten, and they fall off when touched, when the humidity is high, in the diseased part and the soil (generally 2 cm on the surface) can be ginger in the early stage of the disease, the stem base appears water-stained spots and expands day by day, the leaves are yellow, and the disease spots surround the stem base for a week in the later stage of the disease, resulting in the gradual decay of the stem base tissue. Due to the obstruction of water and nutrient transport, the main stem of the shoots dried up and died from top to bottom.

<> ginger rot neck disease is the most serious disease in the process of ginger planting, which is also called ginger rhizome base rot, which is an infectious disease caused by Pythium infection. It is highly contagious, mainly harming the roots and ginger, infected ginger is initially water-stained, ginger mainly prevents ginger blast and soft rot! It is recommended to kill 3,500 times the inner ginger seeds, soak them for 5 minutes, dry them and then plant them!

It can greatly reduce the above diseases and root diseases! After planting, DuPont can be used to kill three thousand 1500 times spray ginger seedlings! Or 100 grams can kill three thousand.

There are mainly ginger rot disease, spot disease, anthracnose and so on. Among them, ginger rot disease, also known as ginger blast, is the most common in ginger producing areas and a devastating disease that occurs in various ginger areas. The yield of the diseased plot is generally reduced by 10% to 20%, and the heavy one reaches more than 50%, and the insecticide of thiamethoxam or phosphine octathion granules is applied to the soil.

When the ginger grows to three buds and one core, spray the first insecticide and fungicide, and then apply the pesticide according to the disease situation. This is just my personal operation, I hope it helps you.

Maggots are mainly harmed by larvae gathered in the bulbs and tender stems of green onions, garlic, leeks, cabbage, etc., and the first hatching larvae are first harmful to the base of the leaf sheath or the upper end of the bulb, and the young stems of the underground are mainly harmed in spring and autumn, causing underground stem rot, sowing methods and techniques: select sunny and warm weather for sowing, keep 1-2 short strong buds for each seed block, remove the rest of the weak buds, and eliminate the diseased ginger with black sections. When sowing, it should be watered thoroughly along the furrow first.

Place the seed buds horizontally facing south or southeast in the furrow.

Some antibiotics should be used, because this is the only way to better protect the growth of crops.

50% copper succinate wettable powder, antibiotics, 70% dixone wettable powder liquid, agricultural streptomycin or neophytomycin, these agents can be used to cure ginger rot.

Before ginger planting, soil disinfection was carried out, and microbial fertilizer was applied in the field, and the root rot was diluted 300 500 times to reduce the number of pathogens in the soil and protect the root system from infection. If root rot still occurs during planting, drip irrigation should be carried out in time to reduce soil soil-borne diseases and dead trees and increase yield.

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.

First, it should not be in a very humid place that is prone to flooding.

1. Detoxification, prevention and treatment of viral venereal diseases, bacterial venereal diseases and fungal venereal diseases

Ginger detoxification (toxins and viruses), strengthen seedlings, promote branching, and at the same time prevent and control ginger virus venereal disease, blight, ginger wilt, fungal soft rot and anthracnose, with No. 2 agricultural streptomycin mixture + copper sulfate 25 grams + 20% well gangmycin 1 bag (15 grams). Starting from the seedlings unearthed, once every 10 days, continuous control 4 5 times, can promote the development of new branches, so that a ginger branch from about 10 branches, can be increased to more than 20 branches, the plant produces ginger generally in about 2 catties. The yield per mu can exceed 10,000 catties.

Therefore, to increase the production of ginger, detoxification and prevention of viral diseases are the key. The mixture strengthens the seedlings, promotes branching, and greatly increases the yield at the same time, and also controls ginger blight (mainly harms seedlings, the base of the seedlings turns brown, and the above-ground stems and leaves are yellow), and ginger blight (mainly harms the underground rhizomes, so that the rhizomes become brown and rot, and the above-ground plants wither. The difference between wilt and ginger blast is that the rhizome of wilt is not water-stained, while the rhizome of ginger blast is water-stained).

Ginger root rot is also called soft rot, (first yellowing from the lower leaves, and gradually expanding to the upper leaves, causing the whole plant to yellowing and lodging.) The rhizome is rotten and smelly), which is a fungal venereal disease. Ginger virus venereal disease (linear stripes on the leaf surface, causing yellowing of the whole leaf, plant atrophy, dwarfing, and very low yield).

Because the mixture can effectively detoxify (toxins and viruses), prevent and control viral venereal diseases, and prevent and control soft rot and blight that are compounded with ginger blast, thus greatly reducing the harm of ginger blast. During the prevention and control, the base of the seedling is sprayed to make the liquid infiltrate into the root soil. One acre of ginger can be sprayed with 4 5 sprayers at a time.

Second, the prevention and control of ginger blast, and the prevention and control of blight bacteria and wilt at the same time

Use the fifth mancozeb mixture, because ginger blast is a algae in bacteria. The symptoms of the disease are (the rhizome gradually softens and rots, leaving only the outer skin, squeezing can flow out the watery sap of white rice, there is a smell, the roots are rotten, the leaves turn yellow from the bottom up, and finally the whole plant droops and dies). From the beginning of the disease, once every 10 days or so, continuous prevention and control 3 4 times, the base of the seedling is sprayed during the prevention and control, so that the liquid medicine penetrates into the root soil.

3. Prevention and treatment of ginger leaf spot disease and anthracnose:

With No. 7 powder rust Ningdaizeb mixture, in the initial stage of disease, 7 10 days can be controlled twice.

Fourth, the prevention and control of ginger pests

Use the No. 10 insecticidal mixture to prevent insect infestation. Insecticides can also be added to the above mixtures to prevent insects.

Note: During the growth period of one season, 50 grams of 20% zinc fertilizer can be added for 2 3 times, and 50 grams of 50% boron fertilizer can be added for 2 3 times, which can be added separately or mixed. Because the nitrogen, phosphorus and potassium of ginger are often overfertilized, it is not necessary to add potassium dihydrogen phosphate and urea.

Eh, people who have never planted ginger have copied the books.

My dad planted ginger, and I personally think that ginger rarely gets sick except for ginger blast and nematodes.

These two diseases can be prevented and treated with that wireless good, and the effect is still very good, it seems to be produced by Zhengzhou Master Science and Technology Development, you can search it on the Internet.

Why is this such a general question?

In fact, if the water and fertilizer are well managed, and the prevention work is done well, there will be basically no disease!

Disease is all about prevention!

The agents for the prevention and control of root rot are, 1 methyl tobuzin wettable powder, 2 chlorothalonil wettable powder, 3 sulfur suspension, 4 basic copper sulfate suspension, 5 and lime powder, etc.

Streptomycin, Bacillus thuringiensis, carbendazim, avermectin methyl, Lactobacillus, these agents are very effective.

I think there are pesticides, farm manure, fertilizers, Bacillus subtilis and microbial compounds.

Plant growth regulators should be chosen, pesticides and acaricides should be chosen, which can reduce decay, and then the temperature and humidity of the air should also be controlled, and some herbicides should be chosen to avoid harm to the surrounding environment.

At this time, we must prescribe the right medicine, we should sterilize the soil, and we must choose excellent varieties, and we can choose to rotate cropstubble, and we must do a good job in drainage and flood control, we can choose quicklime or plant ash, you can use professional agents, and we should pay attention to the efficacy.

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.
