CATDOLL : CATDOLL: Is imidacloprid toxic to fish?

1. Is imidacloprid toxic to fish?

Not very toxic to fish.

Because imidacloprid is a drug used to treat parasitic infections in animals, but if used improperly or in excess, it can cause toxic reactions in fish and lead to death.

Additionally, fish fed imidacloprid may die due to problems with diet, water quality, or other environmental factors, so the death cannot be attributed solely to the effects of imidacloprid.

To prevent fish deaths from imidacloprid, the drug should be used correctly and as directed; the fish tank should be cleaned regularly and the water quality tested; proper diet and living conditions should be provided, etc.

At the same time, excessive use of drugs should be avoided to avoid unnecessary harm to the fish.

2. Is Furadan harmful to rice?

No, rice is a cereal crop of the genus Oryza, and its representative species is Oryza sativa. Rice originated in China and India. The ancestors in the Yangtze River Basin of China had planted rice 7,000 years ago. Rice is divided into indica rice and japonica rice, early rice and medium and late rice, glutinous rice and non-glutinous rice according to the type of rice. It is divided into conventional rice and hybrid rice according to the seed retention method. The main rice producing areas in China are mainly the Yangtze River Basin, the Pearl River Basin, and the Northeast. Rice is a direct cash crop. Rice is the staple food of Chinese residents. At present, the domestic rice planting area is 245 million mu for conventional rice and 200 million mu for hybrid rice.

3. Does Furadan harm trees?

The answer is as follows: Furadan is an insecticide, mainly used to control forest pests. The use of Furadan may cause certain damage to trees, especially when used improperly or in excess. Therefore, when using Furadan, it is necessary to use it scientifically and rationally according to factors such as the type of pest, severity and tree species, and follow the instructions for use and dosage to minimize damage to trees.

4. What are the pesticides that are most toxic to fish? And how do you rank them?

1. Safe for fish, plants themselves and compounds and derivatives synthesized according to active structures. This type of pesticide is the active ingredient extracted from plants. In layman's terms, it is a moderately toxic drug, pyrethrins, and genetically modified pesticides.

2. Biological pesticides are safe for fish. These pesticides are biological in nature. Generally, the following pesticides are the least harmful to fish.

3. The toxicity of Beauveria bassiana pesticides to fish is generally reflected in their LD50, a small number of chemical pesticides with higher LD50, botanical pesticides, green muscardine, etc.

4. Rotenone: this requires support from environmental toxicology test data.

5. How to use furadan correctly on chili peppers?

Furadan is a highly toxic pesticide with a long residual period. National policies and regulations expressly prohibit its use on vegetables, so it is better to use other low-toxic pesticides instead.

6. Can furandan be used to mix seeds?

Mixing furadan with seeds has obvious insecticide effects, but the drug residue is quite serious and its use has long been banned.

7. Is Furadan soluble in water?

Soluble in water.

"Flat Frost" was originally an insecticide used to kill mosquitoes and flies. Later, someone found that "Flat Frost" was "more effective" in poisoning birds, and this method was gradually "popularized". "Flat Frost" is scientifically known as "2,3-dihydro-2,2-dimethyl-7-benzofuranyl-methylcarbamate", which is a highly toxic pesticide that can cause poisoning or death as long as it is exposed to a very small amount. It is an organic pesticide with a particularly long residual period. It was originally used to poison underground pests, and later it was used to poison birds. Migratory birds will suffocate to death after pecking at it.

8. Can Furadan fruit trees be used?

Fufurancarb is a highly toxic pesticide and is prohibited from use on fruit trees and vegetables.

9. What are the acute toxicities of pesticides to fish?

Pesticides can enter the body through oral ingestion, skin contact or respiratory tract, and have adverse effects on physiological functions or normal activities of organs, causing poisoning and death of humans or animals. Poisoning caused by three different ingestion methods is called acute oral toxicity, acute skin toxicity and acute inhalation toxicity. In any poisoning, we consider how much ingestion can cause biological death, measured by the lethal median LD50, which refers to the dose required for a chemical substance to cause death in half of the subjects. LD50 is the most important parameter for evaluating the acute toxicity of a chemical substance, and it is also the basic standard for grading the acute toxicity of different chemical substances. The greater the acute toxicity of a chemical substance, the smaller its LD50 value. The toxicity of a pesticide is measured by its smallest LD50 value. From the value you gave, it can be seen that the inhalation toxicity is very strong, reaching 4.76, which can be said to be a highly toxic pesticide. However, the poisoning is not serious if taken orally and in contact with the skin.

10. Can Furadan kill plants?

Furadan cannot kill plants. Furadan is a highly toxic insecticide, mainly in the form of granules, which can be applied to the roots of plants to allow the plants to slowly absorb it, allowing insects with piercing-sucking mouthparts to absorb plant juices and kill the pests.

Since carbofuran is highly toxic, difficult to decompose, and has a long residual effect, it poses a great threat to the safety of humans and animals. Therefore, carbofuran was mainly used on ornamental flowers in the past. Currently, its use has been banned.
