What should I do if Da Jiang Wen gets Jiang Wen, and I urgently ask for help from the master

Weifang Municipal Bureau of Agriculture**.

Ginger warm disease, also known as rot disease or bacterial wilt, the disease occurs suddenly, spreads very quickly, and is not easy to prevent, once the disease occurs, it will die in a large area, or even extinct birth. Last year, our scientific and technological personnel tried 25% of the fungus powder (soil disinfection fungicide) for prevention and control, and achieved good results, the specific methods are: When preparing the land, mix 5kg of the original drug per mu (667 square meters) into poisonous soil, evenly sprinkle it on the surface, and rake it to level the furrow; When watering the ginger after the seedlings emerge, dissolve 5kg of the original drug per mu in 50kg of clean water, and evenly drip into the water for irrigation; When cultivating the ditch, mix 10kg of the original drug per mu into poisonous soil, evenly sprinkle it on both sides of the ginger seedlings, and then cultivate the soil.

According to the above methods, in previous years, there was no disease in the 2000 square meters of ginger fields in the field that was prone to ginger blast.

In addition, for the ginger field that has been diseased, we have taken the following methods to deal with it, so that the disease has been controlled, and the effect is very good: uproot the diseased strains and remove the bacterial soil in the diseased holes; The ginger seedlings within 5m around the diseased plant were irrigated one by one with 100 times the solution of the fungus net, and the dosage of each plant was, and at the same time, the foliar spray was carried out on the whole plot with the 250 times solution of the fungi net.

1: It may be that the soil contains toxins, causing ginger roots to rot, until the ginger plant is not suitable to die (and will infect other ginger plants), saying: dead trees, the reason is "land discomfort", this problem can only be replaced with other crops, after a period of time, a small area of ginger planting test, if it is not possible, plant other adaptable crops.

2: It may be underground fertilizer or insects or ants, you carefully inspect the surroundings of the ginger, including the inside of the soil.

3: If it is only a few plants occasionally, and it does not happen again, it may be that the ginger itself is not a big problem.

4：1.Observe if there is a similar situation of ginger in other people's land in the vicinity (including last year)?

2.Has there been a similar problem with this land before? If you don't have this piece of land before, but someone else has, then it may be who threw the sick ginger to your land, this virus can last for a long time, it is also very contagious, and it can hide in the soil, so as long as there is a source of infection (sick and dead ginger) thrown into the field, it is easy to be infected.

If you have this land before, then you will treat the ginger in advance depending on the situation, and the loss will be smaller (try to look at it from an economic point of view).

5: There is also a possibility of "ginger disease" - "hemp foot disease" is the ginger plant, the ginger skin has many black spots, black pieces, serious black or some rot.

6.: Ask an experienced person to see if he can govern.

That's all I can help you, and I hope it will be useful to you.

I think it's a lack of water in the foliage, so I should water it more in the evening or morning.

To prevent and control ginger blast, chloropicrin.

Chloropicrin is the preferred product recommended by the Ministry of Agriculture, which is an efficient, residue-free environmentally friendly broad-spectrum comprehensive soil fumigation disinfectant, which can effectively control soil nematodes, soil-borne pathogens (fungi and bacteria), underground pests, and is extremely effective for ginger ginger blast, nematode disease (leprosy disease), and heavy stubble disease. It has been used in Anqiu for many years and has obtained good results.

Benefits after use: The soil treated by chloropicrin disinfection can make the seedlings grow healthily, thereby increasing the yield and enhancing the resistance to diseases; Because chloropicrin has a strong killing effect on various nematodes and soil-borne pathogens, it is especially suitable for soil disinfection of perennial continuous stubble planting, improving crop quality, increasing yield, increasing income, early maturity and weeding, no residue in the soil and crops, and no other effects on continuous use.

Ginger blast: ginger blast is one of the most severely punished pests and diseases of ginger in our province, the incidence of the plot is generally reduced by more than 50 percent, ginger blast is a bacterial disease, its pathogen is Pseudomonas solanacear, the onset period is long, the transmission route is many, and the prevention and control is more difficult. Experiments in recent years have proved that crying chloride is currently the most effective agent for ginger warm disease.

Ginger nematode disease:

Ginger nematode disease (leprosy dermatosis) occurs more seriously in local plots, and its symptoms are mainly the slow growth of ginger seedlings in the shoots, the edge of ginger leaves fades green and yellow, and the serious ones are reddish-brown, the ginger roots in the underground part are scarce, and the surface of the ginger block has obvious protrusions, which are skinny, and the use of chlorinated crying can effectively prevent and control nematode disease.

At present, the rainy season is coming, ginger temperature disease has entered the peak period, and the damage is serious, and ginger farmers should seize the critical period of prevention and control. After the rain, the high temperature ginger blast spreads rapidly, if it is not timely, it will spread in a large area until it is out of production, and ginger fever disease is prevented and treated with chloropicrin in time.

The test proved that the whole process of using fertile leaf series fertilizer can enhance the resistance of ginger and effectively reduce the occurrence of ginger blast.

Ginger blast is a bacterial disease that ginger is easily infected, which has caused serious harm to the growth of ginger, ginger blast mainly occurs in the underground rhizome part, but also can occur in the leaf stem and roots, generally more in the upper part of the stem and root near the ground. The ginger disease part is water-stained at first, the surface is dark, the heart turns brown, emits a foul smell, and then gradually softens, the inside is filled with milky white foul-smelling juice, squeeze the white juice by hand, the stem is damaged into dark purple, and then becomes yellow-brown, the internal tissue becomes brown and rotten, the residual fiber, the leaf damage is withered, the leaf color is light yellow, the edge is curled, and finally the whole plant droops and dies. At the beginning of the disease, the following agents can be used to irrigate the roots or spray:

72 agricultural sulfate streptomycin 4000 times, 50 chlorobromoisocyanuric acid (sterilization, sterilization) water-soluble powder 1000 1500 times, 50 succinyl copper fertilizer (DT) wettable powder 500 times, 30 royal copper suspension 800 1000 times; It has been reported that Garinone, sodium disulfonate (Dixone) and Ye Kunning also have certain control effects.
