Fenitrothion Rapid Test For Agricultural Products

Fenthion has contact and stomach toxicity and no systemic properties, but has good permeability on the plant body, has good control effect on chewing mouthparts and predatory pests. Special effects, effective for controlling spider mites but poor spawning. It can be used to control various crop pests such as rice, cotton, sweet potato, soybean, tea and fruit trees, etc., and its residual period is short.

[Steam pressure] 0.80mPa (20 ℃)
[Danger mark] 14 (with drugs), 34 (flammable liquid)
[Main use] It is a contact insecticide, which has special effects on rice cockroach, and leaf roller.

Fenitrothion insecticide is an organophosphate insecticide. Medium toxicity, low toxicity to humans and animals. Rat acute oral LD50 is 400-800 mg / kg, and rat acute percutaneous LD50 is 1200 mg / kg. Fenthion has contact and stomach toxicity, no systemic and fumigation effects, medium residual period, wide insecticidal spectrum, special effects on larvae of Lepidoptera, and can also control pests such as Hemiptera and Coleoptera. The drug is stable to light, easily decomposes when exposed to high temperatures, and hydrolyzes in alkaline media. Iron, tin, aluminum, copper, etc. can cause the drug to decompose, and can be stored in glass bottles for a long time.

Fenitrothion spray is a common type of Fenitrothion insecticide. Rice pests are used to control rice cockroaches. It is applied at the peak of dead heart seedlings and egg hatching. 100% to 125ml of 50% EC is used per 667 square meters, and 50% to water. Spray 75 liters, or pour 400 liters of water. For the prevention and treatment of pupae, it is also applied at the peak of dead heart seedlings and egg hatching. 50 ml of 50% EC is sprayed every 667 square meters, and 50 to 75 liters of water is sprayed or 300 to 400 liters of water is poured. Mix and mix with 13 ~ 20 kg of dry fine soil. When pouring or spraying poisonous soil, the field should maintain a water layer of 3 ~ 5 cm. The control of rice leaf rollers and rice bracts is applied when the second instar larva peaks and the leaves produce "car leaves". Use 100 ml of 50% EC every 667 square meters and spray 50 ~ 75 liters of water. In addition, fenthion has good control effects on thrips, rice weevil, rice leafhopper, rice planthopper, etc. Therefore, the drug is mainly used as an insecticide in rice fields.

The active ingredient fenitrothion is found in a variety of commercial insecticides. Trade names for products containing fenitrothion include Accothion, Agrothion, Bay 41831, Cyfen, Cytel, Dicofen, Fenstan, Folithion, Kaleit, Mep, Metathion, Micromite, Novathion, Nuvanol, Pestroy, Sumanone, Sumithion, and Verthion.
The common name methylnitrophos is used in Eastern Europe.

Toxicity: belongs to the category of low toxicity.
Pesticide pine is moderately toxic to fish, non-toxic to frogs, and highly toxic to bees.
Metabolism and Degradation: The characteristic of fenitrothion is that it migrates faster in the soil and is converted into non-toxic amino fenitrothion due to hydrolysis or microorganisms. It is usually no longer found after 10 days of application.
Residue and accumulation: The rate of metabolism and degradation of fenitrothion is fast, so the accumulation is not strong, but because it has a certain systemic property like dimethoate, the residue period is medium (similar to dichlorvos).
Migration and transformation: The effect of fenitrothion transferred to deep soil by leaching is not great. Under natural conditions, the annual moving distance is 35cm. After being absorbed by the surface of the gastrointestinal tract and skin, fenitrothion is metabolized in the animal's body Very quickly, it is excreted with urine and feces, so fenitrothion does not move along the food chain.
Dangerous characteristics: Combustible in case of open flame and high heat. Reacts with strong oxidants. Decomposes under heat and releases toxic gases such as nitrogen and phosphorus oxides.

Invasion: inhalation, ingestion, percutaneous absorption.
Health hazard: The minimum oral poisoning dose for humans is 800 mg / kg. Nausea, vomiting, diarrhea and difficulty breathing after poisoning. Acute poisoning manifestations include headache, dizziness, nausea, vomiting, abdominal pain, diarrhea, and salivation. Severe poisoning develops pulmonary edema. Coma and so on.

Chronic symptoms in humans include: general malaise, fatigue, headaches, memory and inattention, anorexia, nausea, thirst, weight loss, cramps, muscle weakness and tremors. Piricide produces typical choline poisoning at sufficient doses.

In case of acute poisoning, immediately remove the patient from the scene, remove contaminated clothes, and thoroughly wash the contaminated parts of the body with soapy water or alkaline solution. Or saline.

Respiratory protection: Wear protective masks during production operations or agricultural use. In emergency situations, you should wear self-contained breathing apparatus for rescue or escape.
Eye protection: Safety mask can be used.
Protective clothing: Wear appropriate protective clothing.
Hand protection: Wear protective gloves.
Others: Smoking, eating and drinking are not allowed on the job site. After work, shower and change clothes. Store clothes contaminated by poisons separately and wash them before using.

Precautions when using Fenitrothion: sorghum and cruciferous vegetables are susceptible to phytotoxicity. Pay attention when using them. Do not mix with alkaline pesticides. If mixing is required, it should be used immediately after mixing. Stop using fruits and vegetables 10-15 days before harvest. It is highly toxic to bees and should not be used during flowering.
The Fenitrothion Rapid Test For Agricultural Products kit provided by BALLYA can effectively detect the presence of fenitrothion residues in agricultural products. This kit is not only simple to operate, but also has a short test time and high accuracy, and the test results comply with EU standards. Can effectively ensure the safety of agricultural products.
