CATDOLL : CATDOLL: How to use erythromycin to control diseases in ornamental fish?

1. How to use erythromycin to prevent and treat ornamental fish diseases?

How to use erythromycin to prevent and treat diseases in ornamental fish? The antibacterial spectrum of erythromycin is similar to that of penicillin G, but slightly broader than that of penicillin G. Gram-positive bacteria and some Gram-negative bacteria are more sensitive to it. Bacteria are prone to develop resistance to erythromycin, but the resistance is not lasting and sensitivity can be restored after 3-6 months of discontinuation of the drug. The drug concentration in each organ reaches the maximum value 1-3 hours after oral administration. It has a synergistic effect when used in combination with streptomycin and sodium bicarbonate. (1) Oral administration: Prepare bait at a concentration of 100 mg/kg body weight and use it for 21 consecutive days to prevent and treat bacterial fish diseases. (2) Spray the entire pond: ① Spray the entire pond with a concentration of 0.2 mg/L and bathe the diseased fish in 2% saline for 15 minutes every day for 3-4 consecutive days to treat vertical scale disease in goldfish. ② Spray the entire pond with a concentration of 0.4-1 mg/L to prevent and treat fin borer disease and tail rot in goldfish.

2. How to prevent splashing when using the toilet?

There are four ways: put paper; toilet splash film; smart bubble type smart toilet; reverse sitting toilet

1. Take a few pieces of dry toilet paper and spread them flat on the water seal of the toilet, which can alleviate the splashing of toilet water to a certain extent.

2. You can buy toilet splash screen. Many hotels and public toilets will install this, and the effect is quite good.

3. There is a kind of smart toilet on the market now, which can produce an appropriate amount of foam to cover the water seal before each use, which can effectively prevent the toilet from splashing water.

4. The posture is like riding on the toilet. The inconvenience is that the feces will easily stick to the toilet wall. You can put a piece of toilet paper on the inner wall of the toilet in advance.

Additional information:

The toilet is also called a toilet bowl, which is a covered bucket for defecation and urination. The invention of the toilet is called a great invention, which solves the problem of people's eating, drinking, defecating and urinating. Later, it gradually evolved into flush toilets using the principles of siphon, spiral siphon, and now the latest jet siphon and super-rotating siphon.

3. How to diagnose uterine nematode disease in fish?

[Symptoms] The scales of the diseased fish stand up due to parasitic worms, and the parasitic sites become inflamed and congested. It often causes secondary bacterial and saprolegniasis. The scales at the site of parasitism show irregular red-purple patterns, and the red worms can be seen when the scales are lifted. [Diagnostic points] The scales of the diseased carp are bulging and red, with special patterns on them. If the scales are turned over, red nematodes can be seen coiled in the scale capsules. [Prevention and control] (1) Clean the pond with quicklime to kill the intermediate host of the uterine nematode, the swordfish.

(2) Soak the fish in 2% to 2.5% salt water.

(3) Apply 1% potassium permanganate to the lesions on the body surface of the diseased fish.

(4) Apply iodine to the lesions on the body surface of the diseased fish.

(5) Use 0.2-0.4 g/m3 of crystalline dichlorvos and spray it throughout the pond.

4. How to prevent corn diseases during the growing season?

1. During the rainy season, since corn seedlings are small and cannot tolerate waterlogging, attention should be paid to clearing ditches and draining water to prevent flooding and waterlogging. During continuous rainy days, waterlogging should be prevented and pests and diseases should be controlled. During continuous rainy days, waterlogging should be prevented and pests and diseases should be controlled.

1. Strengthen field management during the rainy season. First of all, the corn field must be able to drain water. Corn seedlings are drought-tolerant but not flood-tolerant. Clear the ditch to drain water, prevent waterlogging, and prevent pests and diseases in time. Strengthen fertilizer and water management, ensure that the drainage ditch is unobstructed, and prevent waterlogging in the field. Pay attention to drainage and prevention of pests and diseases during the rainy season. Pay attention to drainage and prevent pests and diseases during continuous rainy days.

3. Prevent and control corn diseases, pests and diseases in the rainy season

At present, summer corn has entered the jointing stage, and spring corn is around pollination. The continuous rainy weather has significantly less sunshine, lower temperatures, and more precipitation, which has hindered the pollination of some spring corn and the photosynthesis of summer corn, delaying the filling and maturity of spring corn or the growth of summer corn. This also causes the soil moisture content to be high and the air permeability to be poor, which is easy to cause the occurrence of corn large spot disease, small spot disease, brown spot disease, and local outbreaks of the third generation of armyworms. Therefore, prevention and control measures should be taken in time. The specific prevention and control methods are as follows:

1. Corn leaf spot

During the trumpet-mouth stage, spray with 1000 times diluted 10% fenpropimorph water-dispersible granules, with an interval of 7 to 10 days between each spray, and spray three times in succession.

Second and third generation armyworms

Adult insect trapping technology. ① Insecticide lamp method. During the adult insect outbreak period, install one solar insecticide lamp per 50 mu in the corn field to trap and kill the adult insects at night. ② Sex trapping method. Use a trap equipped with sticky insect sex attractant core, one per mu, and hang it on a pole in the field to trap and kill the adult insects.

Larvae control technology. Larvae are best controlled before the third instar, and the best time to apply pesticides is in the morning or evening when the armyworms are active on the leaves. ① Biological pesticides: Spray 16,000 units of Bacillus thuringiensis (Bt) preparations during the peak hatching period of armyworm eggs. For young larvae, 20% chlorpyrifos suspension No. 3 can be used at a 1000-fold dilution. ② Chemical pesticides: When the insect population density in the corn field is more than 50 heads/100 plants in the third generation, 4.5% highly effective cypermethrin emulsifiable concentrate at a 1000-1500-fold dilution, 10% imidacloprid at a 2000-2500-fold dilution and other insecticides can be sprayed for control.

Technology to protect and utilize natural enemies: Release trichogrammatids or plant flowering plants such as sesame and soybeans on the ridges of the fields, and protect and utilize natural enemies such as spiders and parasitic wasps to control armyworms.

3. Corn Brown Spot Disease

You can use 15% triadimefon wettable powder 1000 times liquid, 10% difenoconazole water dispersible granules 1000 times liquid spray, spray evenly and carefully, protect the upper leaves, especially the leaves above the female ears. In order to improve the prevention and control effect, you can add some Tianfengsu, potassium dihydrogen phosphate, urea and other nutrient fertilizers to the liquid medicine to promote the health of corn and improve its disease resistance. In rainy years, spray once every 7 days, and spray 2 to 3 times in a row. If it rains within 6 hours after spraying, spray again after the rain.

Right-click and select "Local Area Connection" (or the corresponding network card name), select "Properties" Select "TCP/IP Protocol" and click Properties (If it is WIN7, then select TCP/IPv4) Then configure the corresponding parameters If your gateway is (192.168.1.1) Set your computer to (19.168.1.X) This X does not need to be repeated. The subnet mask is generally: 255.255.255.0 Fill in the gateway (192.168.1.1) below and let it automatically obtain the DNS server address. You should set a static IP address for each computer in this way

10. How to use oxytetracycline to prevent and control aquatic animal diseases?

Oxytetracycline can treat certain diseases in fish, such as enteritis, gill rot, vertical scale disease, fin rot, red skin disease, bacterial sepsis and other bacterial diseases.

Dosage: Based on the effective dose, fish should take 50-80 mg/kg body weight per day, twice a day, for 5-10 days.

However, oxytetracycline has cross-resistance with other antibiotics. Treatment with oxytetracycline may not be effective. You can refer to the strength of the antibacterial effect: minocycline> doxycycline> chlortetracycline> tetracycline> oxytetracycline to choose other tetracycline antibiotics. You can also use the medicine accurately according to the symptoms and use less antibiotics. If you must use oxytetracycline, it is recommended to add certain liver-protecting drugs, and use some probiotics after stopping the use of antibiotics to protect the liver and intestines.
