Methyl Parathion Rapid test

Solubility: Slightly soluble in petroleum ether, easily soluble in aliphatic and aromatic halogen compounds, hardly soluble in water and petroleum.

Chinese name: methyl parathion.
Alias: methyl 1605; O, O-dimethyl-O- (p-nitrophenyl) phosphorothioate; Metaphos; Metron.
Danger sign: 14 (highly toxic drugs).
Packing method: plastic bag or double-layer kraft paper bag with full or middle opening steel drum (steel plate thickness 1.0 mm, net weight per barrel does not exceed 150 kg; steel plate thickness 0.75 mm, net weight per barrel does not exceed 100 kg); threaded glass bottle Ordinary wooden cases outside iron capped glass bottles, plastic bottles or metal barrels (tanks).

In addition to methyl parathion hydrolase (MPH), methyl parathion hydrolase can also degrade fenitrothion, ethyl parathion, and chlorpyrifos, but the degradation efficiency decreases in turn. The substrate specificity study of MPH pure enzyme found that the specific activity of hydrolyzing methyl parathion was more than 20 times that of hydrolyzing ethyl parathion.

An efficient organophosphate insecticide, which can be processed into powder, wettable powder and emulsion. Its pesticide effect is the same as parathion. Can control a variety of agricultural pests (aphids, mites and rice tapeworms, leafhoppers, etc.). The maximum allowable residue of the crop before harvest is 0.3mg / kg. Field crops should not be sprayed 15 days before harvest. It is strictly prohibited to use on vegetables. When used on crops such as fruit trees and sorghum, it should be stopped 30 to 45 days before harvest. It is easy to produce phytotoxicity to melon and should not be used.

Properties: This product is a light gray powder, which can be decomposed by alkali.
Function and use: Organic phosphorus pesticide for external use. This product is a special medicine used to control ground pests in the tussah silkworm field.
Pay attention to things:
(1) This product is toxic. Protective equipment should be worn during operation to prevent people or animals from inhaling or touching the wound.
(2) The prepared poison bait should be properly kept to prevent accidental consumption by poultry and livestock. Once human and livestock poisoning is found, detoxify according to organophosphorus pesticide detoxification method.
(3) The used waste packaging cannot be discarded casually, and should be disposed of centrally.

Methyl parathion is a highly toxic pesticide. The acute oral LD50 of pure rats is 61-67 mg / kg, the LC50 of acute inhalation is 120 micrograms per cubic meter (4 liters), the acute non-acting dose of rats is 5 mg / kg, and the oral non-acting dose of dogs is 0.1 Mg / kg / day.

It mainly inhibits the activity of acetylcholinesterase, making acetylcholine unable to hydrolyze, which causes the corresponding symptoms of poisoning and causes neurophysiological disorders.
(1) Acute poisoning: A large number of contacts (oral, inhalation, skin, mucous membranes) in a short period of time cause acute poisoning. The present symptoms include headache, dizziness, loss of appetite, nausea, vomiting, abdominal pain, diarrhea, salivation, diminished pupils, increased respiratory secretions, sweating, and muscle tremor. In severe cases, pulmonary edema, cerebral edema, coma, and respiratory paralysis occurred. Some cases may have heart, liver and kidney damage. A few severe cases develop peripheral neuropathy weeks or months after consciousness is restored. Delayed sudden death can occur in individual severe cases. Reduced blood cholinesterase activity.
(2) Chronic poisoning: There is still controversy. There is neurasthenia syndrome, hyperhidrosis, muscle bundle tremor and so on. Reduced blood cholinesterase activity.

(1) Respiratory system: chest has pressure, nasal congestion, dyspnea, cyanosis, respiratory muscle weakness, and snoring in the lungs.
(2) Digestive system: nausea, vomiting, salivation, abdominal distension, abdominal pain.
(3) Nervous system: headache, dizziness, muscle cramps, convulsions, closed teeth, speech impairment, fatigue, insomnia, restlessness, sweating, etc.
(4) Others: slow heartbeat, decreased blood pressure, skin symptoms such as blisters, erythema, pale, etc., the pupils are narrowed, and the eyes are stressed.

Skin contact: Take off contaminated clothing immediately and thoroughly wash contaminated skin, hair, nails, etc. with soapy water and running water. Seek medical attention.
Eye contact: Raise eyelids and rinse with running water or saline. Seek medical attention.
Inhalation: Quickly leave the scene to fresh air. Keep your airways open. If breathing is difficult, give oxygen. If not breathing, give artificial respiration immediately. Seek medical attention.
Ingestion: Drink plenty of warm water and induce vomiting. Wash the stomach with water or a 2% to 5% sodium bicarbonate solution. Seek medical attention.

The factories and production equipment for the production and processing of organic phosphorus compounds should be closed to prevent spillage; personal protection should be paid when handling and spraying pesticides; wear long-sleeved clothes, masks, hats and gloves when working; Separate storage, prohibit mixed storage with food, strengthen management and education. When using the paddy field, it is necessary to strengthen the skin protection of the hand and the lower third of the calf to prevent pollution and avoid downwind operation. After the application, wait until the content of the water in the field drops below the safe concentration before entering the field, generally about 5 d. In addition, the problem of living poisoning should also be actively prevented. The maximum allowable residue in agricultural crops established abroad is 1 ppm. This product has a long residual period, so spray it on food crops one month before the harvest. Parathion is not used on short-term crops of vegetables.

The mechanism of action and insecticidal spectrum of methyl parathion is similar to parathion, but the substance has lower efficacy than parathion, short residual effect, and low toxicity to humans and animals, but it is still a highly toxic pesticide.
The Methyl Parathion Rapid test kit provided by BALLYA can effectively test whether agricultural products contain methyl parathion residues. 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.
