PE Groves
1 packet
Product Instruction
Storage & shelf-life
At 4~30℃, out of sun light & moisture, 18 months

Test procedure
1. Prepare the buffer solution follow the product instruction.
2. Take 2g samples (tubers--4g, Strip shaped—2g), cut cabbage into pieces about 1 cm. Take the cross-section or epidermis of the tubers into the sample cup, add 10ml of buffer solution. Shake for 1 ~ 2mins, pour out the extract solution, and stand for 2mins as test sample. If the extract is turbid or too many impurities, it can be measured after filtering.
3. Prepare the test card and the sample stand for room temperature and use the test card within 1h if unsealed.
4. Take out and place the test card on the flat desk. Pipette 2-3drops of sample, (about 60-80µl), into the sample well (no bubble).
5. Reacting for 3-5mins, then read the result. Result after 30mins is invalid.

Interpretation of results
Negative: the color of line T is same or stronger than C
Positive: line C is stronger than T only line C appear
Invalid: line C does not appear or only the line C appear.

    Trivia questions : What is profenofos?

    About profenofos

    Profenofos structure

    Chinese other names: bromochlorophosphine, parabenphos
    Common English name: profenofos
    Chemical formula: O- (4-bromo-2-chlorophenyl) -O-ethyl-S-propyl-thiophosphate.

    Profenofos mode of action

    Like other organophosphates, the profenofos mechanism of action is via the inhibition of the acetylcholinesterase enzyme. Although it is used in the form of a racemate, the S(-) isomer is a more potent inhibitor.

    Preparation method

    Preparation method one
    In the presence of acid binding agent, O-ethyl-S-propylthiophosphoryl chloride is condensed with 2-chloro-4-bromophenol.
    O-ethyl-S-propylthiophosphoryl chloride can be prepared from (C2H5O) 2PCl, C2H5OPCl2, PCl3.
    Preparation method two
    Using ethanol as a solvent, O, O-diethyl-O- (2-chloro-4-bromophenyl) phosphate reacts with potassium sulfide to form an intermediate compound, and then reacts with bromopropane to produce probromophosphate.

    What is the use of Profenofos?

    Profenofos insecticide

    1. Asymmetric organophosphate pesticides. It has contact killing and stomach poisoning effects, no systemic action, wide insecticidal spectrum, and can control harmful insects and mites on cotton and vegetable fields. The application dose is 2.5 to 5.0 g of active ingredient per 100 m2 for stab-suction pests and mites; 6.7 to 12 g of active ingredient per 100 m2 for chewing insects.
    2. It is used to control various pests of cotton, vegetables, fruit trees and other crops, especially the resistant cotton bollworm
    3. It is a systemic broad-spectrum insecticide that can control harmful insects and mites in cotton and vegetable fields.
    4. It is a ternary asymmetric non-systemic broad-spectrum insecticide, which has contact and stomach toxicity, and can control cotton, vegetables, fruit trees and other pests and mites. The application dose is based on the active ingredient, 16-32 g / mu for stab-sucking insects and mites, and 30-80 g / mu for chewing insects. It has special effects against the cotton bollworm, and the amount is 30-50 g / mu. Mu preparation.

    Profenofos 50

    50% profenofos EC has a good insecticidal effect and control effect on young larvae of cotton bollworm. 7 days after the treatment, the correction control effect was stable at more than 90%. The control effect of 50ml / 667m2 is equivalent to that of the control agent, but the difference is not significant; 62.5 ml / 667m2 is slightly better than the control agent, and the difference is significant.
    50% Propofron Emulsion Oil 37.5 ~ 62.5ml / 667m, 50kg spray with water to control cotton bollworm, no obvious symptoms of cotton were found.

    Profenofos toxicity

    Profenofos is a poisonous pesticide for the human body. It enters the body through oral or skin infections. It can also cause eye injury, respiratory tract inhalation, and accidental injury through the vapor, powder or aerosol of profenofos.

    Profenofos poisoning

    Symptoms of poisoning: Acute poisoning usually occurs within 12 hours. Mild: headache, dizziness, nausea, vomiting, sweating, weakness, chest tightness, blurred vision, loss of appetite, etc. Cholinesterase activity in whole blood usually drops to 70-50% of normal. Moderate: In addition to the above symptoms, there are mild dyspneas, muscle tremor, diminished pupils, heart pals, unstable walking, sweating, salivation, and abdominal pain,  diarrhea. In severe cases, coma, seizures, dyspnea, foaming in the mouth, urinary incontinence, convulsions and respiratory paralysis may also occur.

    Profenofos poisoning treatment

    First aid treatment: immediately sent to the hospital for symptomatic treatment.
    1. Subcutaneous or intravenous injection of 1 to 5 mg of atropine (depending on the severity of the poisoning);
    2. Intravenous injection of 0.4-1.2g (depending on the severity of poisoning);
    3. Prohibit the use of morphine, theophylline, phenothiazine and reserpine.
    4. Immediately cause vomiting, gastric lavage and laxative (vomiting only occurs when awake).

    Profenofos poisoning prevention

    (1) Respiratory protection: During production operations or agricultural use, a self-priming filter respirator (full face mask) must be worn. In an emergency, you must wear a self-contained positive pressure breathing apparatus (SCBA) for rescue or evacuation.
    (2) Eye protection: Protection has been performed in respiratory protection.
    (3) Body protection: Wear protective clothing and neoprene gloves.
    (4) Others: No smoking or eating at the work site. After work, wash thoroughly. It is forbidden to bring work clothes to non-workplaces. Store clothes contaminated with poison separately and wash them for later use. Pay attention to personal hygiene.
