What are the best drugs to kill bacteria, and what are the best fungicides

Sterilizing drugs are usually divided into external and internal use, usually external use is disinfectant solution, commonly used are hydrogen peroxide, iodine, iodine tincture, alcohol, red mercury or gentian violet and other disinfection solutions. In addition, internal use can usually be divided into gram-positive drugs that kill gram-positive bacteria, and penicillins such as amoxicillin and roxithromycin, clindamycin or chlorin.

The first and second generation cephalosporin antibiotics have a good effect on killing diseases mainly infected by gram-positive bacteria. Drugs that kill Gram-negative bacterial diseases are commonly used third-generation cephalosporin antibiotics and quinolone antibiotics, antifungal drugs such as voriconazole and fluconazole, and anti-anaerobic drugs such as metronidazole and tinidazole. Hydrogen peroxide is a commonly used disinfectant in clinical practice, but hydrogen peroxide is actually mainly used for disinfection of bacterial infections.

Hydrogen peroxide has no clear effect on fungi, and in clinical cases such as tinea manudo, tinea pedis, tinea corporis, onychomycosis and other fungal infections, hydrogen peroxide is not a commonly used drug. Generally, hydrogen peroxide is used to disinfect wounds, and if the wound is combined with anaerobic bacterial infection, it is also better to use hydrogen peroxide for disinfection. However, when hydrogen peroxide is disinfected, it will cause patients to have obvious pain sensations, so patients must not try to use hydrogen peroxide at home to ** their own fungal diseases, if not well controlled, it will cause serious damage to normal ** tissues.

Bacterial diseases mainly include: bacterial brown spot, canker, horn spot, leaf blight, soft rot, bacterial wilt, wildfire, ginger blast, bacterial disease of flower seedlings with neck base rot, bacterial perforation of peach trees, bacterial stripe spot disease of rice, white leaf blight, root cancer, etc.

Characteristics of bacterial diseases.

Relevant studies have shown that there are more than 500 kinds of plant bacterial diseases that have been recorded, which is a relatively difficult disease to control.

Bacterial diseases are diseases caused by bacterial bacterial infection, and the bacteria that invade plants are rod-shaped bacteria, most of which have one to several flagella, which can invade through natural orifices (stomata, skin pores, water holes, etc.) and wounds, and spread by running water, rainwater, insects, etc., and spend the winter in diseased residues, seeds, and soil, and are prone to disease under high temperature and high humidity conditions.

The biggest feature of bacterial diseases is the production of "bacterial pus", which is the biggest difference from fungal diseases. The common symptoms of bacterial diseases are rot, wilting, and deformity, and common soft rot, canker, bacterial wilt, spot disease, etc. are often caused by bacteria.

Here are a few common symptoms of bacterial diseases:

Classification of symptoms of bacterial diseases.

1. Spot type:

The disease caused by Pseudomonas infection, the leaves are the main susceptible sites, which are spotted, water-stained at the beginning, and there is a yellow halo around the lesions, which is manifested as acute necrosis at the lesions.

Such as bacterial brown spot disease in rice, bacterial horn spot in cucumber and watermelon cotton, bacterial leaf spot disease such as chrysanthemum begonia, cruciferous bacterial black spot disease (Chinese cabbage, cabbage, radish, cauliflower, etc.), lettuce, tomato and watermelon bacterial spot disease, etc. Plants of all families have the disease of being infected.

2. Leaf withering type:

Caused by Chanthomonas infection, the general leaf infection, the initial onset of the disease in the leaf edge of the water-soaked small spots, after the expansion of the lesion is irregular, the edge of the yellow halo, ** light brown, and to the middle of the leaf, eventually leading to leaf wilting.

Such as rice white leaf blight, cucumber bacterial leaf blight, konjac bacterial leaf blight, leguminous bacterial leaf blight, bean bacterial blight, etc. It mainly harms leaves, petioles, stems, tendrils and fruits.

3. R. solanacear:

Generally, Pseudomonas infects the vascular bundles of plants, blocking the conduction pathway, causing plant stems and leaves to wilt, which is a soil-borne disease. Plants that did not show any abnormalities in the aboveground parts in the early stage of the disease suddenly lost their vitality during the day, and the entire aboveground parts withered. Cloudy days and morning and evening returned to normal, however, it withered soon after, and the plants quickly wilted and died, with their stems and leaves still green.

The browning part of the diseased stem is squeezed by hand, and the milky white bacterial liquid is discharged. The disease is prone to occur under the conditions of high temperature and high humidity, continuous cropping of heavy cropping, clay soil, stagnant water in the field, acidic soil, and partial application of nitrogen fertilizer. Such as tomato wilt, potato blight, strawberry wilt, etc.

1. 84 disinfectant.

1. It is used for the disinfection of dysentery, enteritis, diarrhea and purulent contaminants caused by dysentery bacillus, Escherichia coli and other intestinal pathogenic bacteria, and the liquid medicine can be used for disinfection for 10 minutes in a ratio of 1:250.

2. It is used for the disinfection of viral colds, viral pneumonia and other patient contaminated items infected by different viruses, and the liquid medicine can be disinfected in a ratio of 1:20 1, and the aqueous solution spray prepared by peracetic acid can kill a variety of bacteria, fungi and viruses.

Second, the new Jieer extinguished.

The aqueous solution spray prepared has a strong killing effect on the general disease bacteria. When using, take care to avoid contact with soap or alkali.

3. Sodium hypochlorite.

It is prepared to spray an aqueous solution containing chlorine 30 10-6 50 10-6, which has a strong killing effect on Escherichia coli and Salmonella leukarrhoea. When preparing, water with a higher pH value should not be used as a diluent to slow down the excitation, and it should be prepared and used at the same time.

Fourth, strong disinfectant.

The prepared aqueous solution spray can quickly kill many pathogenic bacteria such as Staphylococcus aureus and Escherichia coli. Do not use with reduced disinfectant.

Fifth, 100 poisons.

Prepared to make 1 200 300 times of aqueous solution spray, can kill Escherichia coli, Salmonella, etc., and also has a certain effect on chicken Marek's virus, chicken Newcastle disease virus, etc.

6. Iodophor. Disinfection, mucosal irrigation, pre-operative disinfection, can also be used for bacterial infection of mucous membranes and mildew removal of instruments and environments.

In 2015, fluazoleamide overtook the "sibling brother" pyridoxamide that has occupied the leading position for many years, and sat on the top spot in the SDHI fungicide market; In 2016, this advantage was maintained. It is considered by the academic community to be the best broad-spectrum fungicide.

The best fungicide, that is, the natural sun, non-toxic and pollution-free sterilization is the best.

The best drugs for sterilization, anti-inflammatory, and anti-itching can be divided into oral, external, and intravenous use. Oral drugs can choose cephalosporin antibiotics, or azithromycin granules or roxithromycin capsules. Topical drugs can be used with lactate ethacridine solution, compound cork liniment, wet compress to the affected area, twice a day, 20 minutes each time, after 20 minutes, you can apply mupirocin ointment, compound polymyxin B ointment.

The drugs at the static point include penicillin sodium, cefoxitin sodium for injection, clindamycin injection, levofloxacin injection, and the scope of application of such drugs is mainly on the surface of the ** relatively large erosion surface, with purulent exudation and purulent scabs. It is necessary to refrain from alcohol during the ** period.

Summary. Which is the best fungicide.

The strawberry fungicide is good.

Jinpin Ike-Strawberry Special Type is a special high-quality fungicide launched according to the difficult diseases caused by strawberries. It is especially effective on black mold, blue chong, blight, anthracnose and root rot on strawberries!! It can achieve the special treatment of Yuhui early effect when the disease is controlled and the disease plant resprouts in two days, which is safe and efficient, and has no resistance.

What kind of medicine can be used to continuously show flower buds.

Pro-flowering period generally does not carry out foliar spray to prevent and control diseases, generally with Aktai + Jiamei dividend 1000 times liquid root irrigation, and at the same time at night with isoprocarb and other tobacco agents for control, but in strict accordance with the instructions, timely ventilation. If the disease is severe, avoid the time of pollination at noon. After the strawberry buds appear, 20-25 during the day, 8-10 at night, the highest demolition shout during the day does not exceed 28 brigades of mountains, not low but sensitive to 15, the temperature is too high and too low will affect the normal pollination of strawberries, and the night should not be less than 5, in order to prevent frostbite buds.

If you want to make the orange strawberry continue to bloom and bear fruit, it is also very important to fertilize the strawberry at the flowering and fruiting stage: you can drip irrigate "Harveyt" at the young fruit stage of strawberries, drip irrigate "Harvey Fruit" at the fruit expansion stage, and drip irrigation "Harvey" and "Root Fertilizer" if the overall growth is weak. Spray "Hua Duo Le" and "Nu Extract Calcium and Boron" during the flowering period, spray "Nu Cui Calcium Boron" and "Guo Duo Le" after flowering, and spray "Harvey Fruit" and "Yang Duo Le" during the expansion stage, which can take into account foliar growth, fruit expansion and flower bud differentiation.

Promote rapid seedling slowing and explosive rooting; After surviving, the defense group sprayed "Naibai" and "Naipu 9", and sprayed 2 or 3 times continuously every 7 10 days; Strawberry seedlings are weak to Bidong drip irrigation or spraying "Havetong", strawberry seedlings are strong drip irrigation or spraying "Harvey flowers", do the above work, cultivate seedlings suitable for high yield.
