Test kit
10 pcs
Pipette
10 pcs
Buffer Solution
1 bottle
PE Groves
1 packet
Product Instruction
1
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: line T is same or stronger than line C
Positive: only line C appear or line T is hardly appearing
Invalid: line T&C does not appear or only the line T appear.

Trivia questions : What is Chlorpyrifos?

About Chlorpyrifos

Chlorpyrifos is a broad-spectrum insecticide and acaricide, which is highly volatile in the soil. It is suitable for controlling pests and mites on various crops such as citrus, cotton, corn, apple, pear, rice, peanut, soybean, wheat and tea tree. Chlorpyrifos is an efficient and low-toxic organophosphorus pesticide, which can inhibit cholinesterase activity and block plant photosynthesis, so it is both a pesticide and a herbicide.

Chlorpyrifos structure

Properties: white crystal with slight thiol smell
Density (g / mL, 25/4 ℃): 1.398
Melting point (° C): 42.5-43
Boiling point (° C, normal pressure): 200
Refractive index: 1.56
Flash point (° C): 181.1
Water-soluble: Slightly soluble in water, soluble in most organic solvents.

How does chlorpyrifos work

1. Centipede is an acetylcholinesterase inhibitor, a phosphorothioate insecticide.
⒉ Inhibition of the activity of acetylcholinesterase AChE or cholinesterase ChE in the nerves in the body destroys the normal nerve impulses and causes a series of poisoning symptoms: abnormal excitement, spasm, paralysis, death.

Chlorpyrifos uses

Chlorpyrifos pesticide

1. It has triple effects of stomach poison, contact killing and fumigation, and it has good control effect on various chewing and sucking mouthparts pests on rice, wheat, cotton, fruit trees, vegetables, tea trees.
2. Good compatibility when mixed, can be mixed with a variety of pesticides with obvious synergistic effects (such as chlorpyrifos and triazophos).
3. Compared with conventional pesticides, it has low toxicity and is safe for natural enemies.
4. Wide insecticidal spectrum, easy to combine with organic matter in soil, special effect on underground pests, and its duration is more than 30 days.
⒌ No systemic effect, to ensure the safety of agricultural products and consumers, suitable for the production of pollution-free high-quality agricultural products.

Chlorpyrifos insecticides

Chlorpyrifos is a moderately toxic organophosphate insecticide that can be absorbed through inhalation, ingestion, and transdermal absorption, and is highly volatile in soil. It is suitable for controlling pests and mites on various crops such as citrus, cotton, corn, apple, pear, rice, peanut, soybean, wheat and tea tree. Chlorpyrifos is an efficient and low-toxic organophosphorus pesticide, which can inhibit cholinesterase activity and block plant photosynthesis, so it is both a pesticide and a herbicide.

Chlorpyrifos toxicity

Chlorpyrifos health effects

Chlorpyrifos is an organophosphate pesticide known for its damaging effects on the human nervous system. Like all OPs, chlorpyrifos blocks an enzyme (acetylcholinesterase) that our brains need to control acetylcholine, one of the many neurotransmitters mediating communication between nerve cells. These neurological effects pose especially elevated risks for children as their brains and nervous systems develop.

Chlorpyrifos poisoning

Symptoms of acute poisoning in the human body are first manifested in tears, runny nose, sweating and increased saliva secretion, nausea, headache, dizziness, and weakness. Further muscle distortion, weakness, tremor, dyskinesia, blurred vision, nausea, vomiting, and dilated pupils can occur. In severe cases, pulmonary edema, incontinence, and coma occur. Post-exposure symptoms in children differ from adults, such as seizures, muscle weakness, drooling, pupil contraction, lethargy, and coma. Delayed neuropathy can occur with high dose acute exposure.

Chlorpyrifos poisoning treatment

Patients need to be given a thorough gastric lavage. At the same time, a small gastric tube can be left and repeated gastric lavage. Drug treatment can use the organophosphorus pesticide-specific detoxification drug Jiedingding. The principle of medication is that the early dose should be sufficient, and it should be applied multiple times. The course of treatment is generally 3-5 days. Atropine can be used to antagonize the produced M nutrition effect. Severe patients can be treated with hemoperfusion.

Chlorpyrifos ban

The pesticide residue verification test results show that even if chlorpyrifos is used according to the correct method and dosage, there is still a risk of exceeding the standard of pesticide residues; according to the short-term risk assessment results of the large share allocation data, the use of chlorpyrifos on cabbage is a risk to children, and the general population is therefore In order to better protect the public's life and health and reduce risks, the Ministry of Agriculture decided to gradually ban this pesticide on vegetables.

Chlorpyrifos California

Beginning in early 2020, California will ban the sale of the pesticide chlorpyrifos which state environmental officials say has been linked to brain damage and other health defects in children.

Chlorpyrifos european union

The European Food Safety Authority released a statement in July 2019 which concluded that the approval criteria for chlorpyrifos which apply to human health are not met. Their literature review concluded that there is no evidence for reproductive toxicity in rats, but that chlorpyrifos is potentially genotoxic. The report stated that chlorpyrifos is clearly a potent Acetylcholinesterase inhibitor, that it can be absorbed by ingestion, inhalation, and through the skin, and that epidemiological evidence supports the hypothesis that it is a human developmental neurotoxin that can cause early cognitive and behavioral deficits through prenatal exposure.

Summary

Routine monitoring of the quality and safety of agricultural products in recent years has found that the use of chlorpyrifos is likely to cause vegetable pesticide residues to exceed standards. Therefore, in order to better protect the public's life and health and minimize risks, the Ministry of Agriculture decided to gradually ban this pesticide on vegetables.
The Chlorpyrifos Test For Agricultural Products kit provided by BALLYA can effectively detect whether Chlorpyrifos residues are contained 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.
