What medicine is used to disinfect and kill insects in fish ponds?

Question 1: What pesticides are commonly used in pond culture? It is best not to get sick, which will easily lead to fish injury. Disinfectants such as chlorine dioxide and trichloroisocyanuric acid can be used for preventive treatment. Different parasites use different drugs. For example, melon worms can't be killed with copper sulfate.

Question 2: Do you want to disinfect the fish pond or kill the insects first?

Pay attention to the application of pesticides in fish ponds:

There are three kinds of second medication, 1, twice a day; 2. Continuous use for two days; 3. Use every other day. 4. There are many more detailed usage methods and precautions for the above three auxiliary medication methods. ① Use twice a day, the first time in the morning, two-thirds of the dosage, and the second time two hours later, use up the remaining one-third; (2) From the upper air outlet to the lower air outlet, the whole pool must be splashed with water, and no centralized spraying is allowed. 2. Use for two consecutive days ① Use 100% on the first day and 70% on the second day; (2) From the upper air outlet to the lower air outlet, the whole pool must be splashed with water, and no centralized spraying is allowed. 3. Use every other day: use one course of treatment on the first day and the second course of treatment on the second day (recommended for stubborn parasites). 4. Precautions: ① Insecticide must be used in sunny days. If it is used in a large area, you must observe the weather in the past week. They can only be used without much change, and the effect will be better if the temperature is higher. If you use it twice a day, you must use it in the morning for the first time. The second time should be used before 2 pm at the latest. Or both in the morning. (3) The use of drugs in large water surface must be accurately measured, and the water depth above 2.5 meters is calculated according to the information water area of the comprehensive village; Below 2.5 meters, calculated by water depth.

Question 3: Don't bother with the drugs specially used for sterilization and pest control in fish ponds. Now the new xipu koi fish fishpond filtration system is popular in the market. Dozens of strains, such as double-ion electrostatic filter, Xipu bacteria, nitrifying bacteria, photosynthetic bacteria and aerobic bacteria, all have a carrier, which decomposes nutrient-rich substances in water when it flows, and then removes algae and bacteria in water through overflow ultraviolet sterilization equipment, thus achieving the effect of water purification.

Question 4: How to kill insects and sterilize fish ponds in July?

Sterilization method: I mainly talk about drugs. For specific precautions and dosage, please refer to the precautions and dosage of fish medicine (remember)

The first choice for sterilization and pH adjustment to prevent diseases: quicklime, hydrated lime, bleaching essence, bleaching powder, bleaching powder essence (this is a good thing).

The second choice for sterilization treatment of algae is formalin, daily chemical, calcium oxide, copper sulfate, acetic acid and sodium chloride.

The second choice for sterilization and water improvement is sodium bicarbonate, sodium bicarbonate, ferrous sulfate, ammonium sulfate, borax, etc.

Sterile chemical fertilizers kill insects and help fish grow: copper sulfate, calcium peroxide, peroxyacid, potassium permanganate, copper chloride, copper chelate, etc.

The above answers are true and can be learned. Please accept the answer, it is not easy, feasible, and cherish it.

Question 5: Can I feed fish to the fish pond on the day of disinfection and disinfestation?

, insecticidal, the most

It will take at least two hours.

Feed the fish tomorrow,

It's safer this way

Question 6: How to disinfect the fish in the fish pond? First, disinfect with quicklime. 1. Disinfect the dry pool, drain or leave the water depth at 5~ 10 cm, and the dosage is 1~3 kg/m2. During disinfection, dig several ponds of suitable size around the pond to let water flow in, then put the quicklime into the pond to dissolve, and immediately sprinkle it all over the pond while it is hot. The next day, a long-handled mud harrow was used to push the harrow at the bottom of the pond, so that the lime slurry and the pond mud were fully mixed and the disinfection effect was improved. The second is disinfection with water. The dosage of quicklime is 2~5 kg/m2. After the quicklime is dissolved, it is evenly sprinkled on the whole pool water while it is hot.

Second, tea bran disinfection. Water can fertilize water and promote the growth of shrimps and crabs. The dosage is 100g/m3. Mash the tea bran first, then soak it for 1~2 days, and then spread the residue juice evenly in the whole pool.

Bleaching powder disinfection. Dry pool disinfection, bleaching powder dosage is 10~30 kg/m2. The dosage of water disinfection is 20~50 kg/m3, and bleaching powder is mixed with water and evenly sprinkled in the whole pool.

Third, croton disinfection. Croton is effective in disinfection of shrimp and crab water surface. The dosage is 2-8g/m3. Mash croton, put it in a bucket, soak it in 3% salt water, seal the mouth of the bucket, and spread the residue and juice evenly in the whole pool after 2~3 days.

The above drugs have certain killing ability to enemy organisms and pathogens, and can be used alone or in combination according to the ratio of 1: 1. After disinfection, before stocking, put a few fish, shrimps and crabs to test the water, and then stock them in large quantities after confirming that the toxicity disappears.

Question 7: After a few days of disinfection, the fish pond can kill insects. Generally speaking, the prevention and control of fish pond diseases is to kill insects first and then disinfect them.

Question 8: Should the fish pond be disinfected or disinfected first?

Question 9: What is the best disinfection method for fish ponds? Quicklime is the cheapest disinfectant and insecticide.

1, quick lime slurry disinfection. Every 667 square meters (1 mu) fish pond uses 5~7.5 kilograms of quicklime, which is dissolved in 10 ~ 15 kilograms of water, repeatedly stirred into lime slurry, and then evenly scattered in the fish pond to achieve the purpose of disinfection. If there is water in the fish pond, the dosage of quicklime should be increased to 667 square meters 12.5~ 15 kg. After spraying the quicklime slurry for 70 days, the fish can be put in for feeding.

2, bleaching powder disinfection. Generally, the chlorine content of bleaching powder is about 30%, and hypochlorous acid and alkaline calcium chloride are released after wet decomposition. The new ecological oxygen released by hypochlorous acid has a strong bactericidal effect. Use 1.4 ~ 1.5 kg bleaching powder every 667 square meters of fish pond (water depth 1 m) and sprinkle it evenly on the water surface to achieve the purpose of disinfection. Sprinkle bleach for 50 days before releasing the fish.

Usage: 20 grams of bleaching powder per cubic meter of water. After the bleaching powder is dissolved in water, immediately sprinkle the pool water. Bleaching powder is easy to volatilize and decompose in the air, so it must be stored in a sealed way and isolated from the air. It should be stored in a cool and dry place to avoid invalidation. It is best to use ceramic magnetic cylinders and wooden utensils for loading bleaching powder, not metal utensils. Wear a mask when using, and sprinkle the medicine on the windward side.

3. Mixed disinfection of quicklime and bleaching powder. 6.5~8 kg of quicklime and 0.65 kg of bleaching powder are used for every 667 square meters of fish pond (water depth 1 m), and good disinfection purpose can be achieved by mixing or evenly spreading them on the water surface of fish pond. After 70 days of application, fish species can be put into culture. Quicklime produces strong alkali when it meets water, so it has strong sterilization and killing ability. About half a month before the seeds are put into storage, they should be disinfected with lime on sunny days. During disinfection, 7- 10 cm of water should be left in the fish pond to make the scattered quicklime evenly distributed. The dosage of quicklime is generally 60-75 kg per mu, and 50-60 kg is used in fish ponds with less silt.

Usage: First dig some small pools around the pool, and then put the quicklime into the pool to absorb water and deepen it. Before cooling, spread it around with a wooden shovel. Be sure to spread the mortar evenly on the floor. If the fish pond is narrow on both sides, it can be directly sprinkled, and the quicklime can be pulped in wooden barrels and directly sprinkled on the ground. After several hours, use a long-handled mud rake to stir the mud lime slurry at the bottom of the pool, so that the mud lime is evenly mixed and the disinfection effect is increased. Fish ponds with inconvenient drainage should be disinfected with water. When the water depth of each mu of fish pond is 1m, it needs about 125- 150kg of quicklime.

Question 10: Can pesticides and fungicides be used together in fish ponds? Generally speaking, two drugs can't be used together, except those that don't react. As for what reacts and what doesn't, there are too many drugs. No one has done the experiment one by one, so I think if there are bugs, they should be killed first, then disinfected, and it is best not to use them together. Once you react, it's basically poison, hehe.
