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 C&T appear
Positive: only line C appear
Invalid: line T&C does not appear or only the line C appear.

Trivia questions : What is chlorothalonil?

Chlorothalonil

Pure product is white crystal, melting point 250-251 ℃, boiling point 350 ℃. Vapor pressure is less than 1.3Pa (40 °C). The solubility in water is 0.6 ppm, 2 g / kg in acetone and 8 g / kg in xylene. The industrial product content is about 98%, and it is stable under alkaline and acidic aqueous solutions and ultraviolet radiation. Formulation 2.5%, 5% granules, 75% wettable powder.

Chlorothalonil chemical structure

Chemical name: Tetrachloroisophthalonitrile
Relative molecular mass: 265.91
Solubility at 25 ℃: 0.9 mg / L in water, 80 g / L in xylene, 30 g / L in cyclohexanone and dimethylformamide, 20 g / L in acetone and dimethyl sulfoxide, kerosene <10 g / L. Thermal stability lies in ambient temperature, is stable to ultraviolet light (aqueous medium and crystalline state), stable in acidic and slightly alkaline solutions, and slowly hydrolyzes at pH 9.

Chlorothalonil mode of action

The mechanism of action is that it can interact with glyceraldehyde triphosphate dehydrogenase in fungal cells and bind with cysteine-containing proteins in the enzyme, thereby destroying the activity of the enzyme, destroying the metabolism of the fungal cells and losing viability. Chloride has no systemic conduction effect, but after spraying on the plant body, it has good adhesion on the body surface and is not easy to be washed away by rainwater, so the validity period is long.

What is chlorothalonil used for

Chlorothalonil fungicide

Chloride fungicide is a non-systemic broad-spectrum fungicide, which has a preventive effect on a variety of crop fungal diseases. It can interact with glyceraldehyde 3-phosphate dehydrogenase in fungal cells. The protein binding of plate cystine destroys the enzyme activity, destroys the metabolism of fungal cells and loses vitality. The main role of chlorothalonil is to prevent plants from being attacked by fungi. Chloride has good adhesion on the plant surface, so it has a long period of efficacy, generally 7-10 days. This product has not yet exhibited resistance, is easily soluble in water, and can exert a good effect on the prevention of regular spraying or the prevention of the spread of diseases when the disease occurs violently.

Bacteriochloride smoke remover, dorman bai wettable powder, bai manganese zinc wettable powder, bai rot smoker, bai ethyl aluminum wettable powder, 40% baizolazole suspension agent, 28% bavin Wettable powder, bai · jiashuang suspension seed coating agent, bai · jiashuang wettable powder, Bai · fu · fu zinc wettable powder, 18% baishuang urea suspension, BJQ-114 antifungal agent and so on.

Chlorothalonil df

Dry suspension is one of the pesticide formulations. Dehydrate from aqueous suspension. As the name suggests, dry suspension (English code df). In recent years, the Pesticide Inspection Institute of the Ministry of Agriculture has used dry suspension agents in combination with water-dispersible particles (collectively referred to as water-dispersible particles) (English code wdg). In fact, this is the difference in processing methods, df is wet granulation and wdg is dry granulation. 82.5% chlorothalonil df is a well-known dry suspension agent in China.

Chlorothalonil trade names

Chlorothalonil 720 label

Chlorothalonil 720 g / L is a commonly used specification for the production of chlorothalonil in China.

Chlorothalonil fungicide label

Chlorhexidine is a broad-spectrum protective fungicide, a contact killer, mainly controlling various fungal diseases. It does not have a systemic conduction effect, nor is it absorbed from the spray site and the roots of the plant. After spraying on the plant body, it has good adhesion on the surface of the plant body and is not easily washed away by rain. Its strength is to sterilize the plant surface and has no effect on bacteria in the plant. It is very suitable for foliar spraying and may be resistant to carbendazim. Switching to chlorothalonil for control will work well.

Is chlorothalonil safe?

Chlorothalonil toxicity

It is a low-toxic fungicide. The pure product is a white odorless powder with a boiling point of 350 °C and a melting point of 250-251 °C. It is slightly soluble in water and soluble in organic solvents such as xylene and acetone. The original powder contains 96% of active ingredients, the appearance is light yellow powder, slightly irritating odor, stable to acids, alkalis and ultraviolet rays. Low toxicity, has obvious stimulating effect on rabbit eyes and cornea, can produce corneal opacity, and is irreversible, but has no such effect on human eyes. It has irritating effect on the skin of a few people. Very toxic to fish. The acute oral LD50 of the original powder rat and the rabbit acute percutaneous LD50 were both greater than 10000 mg / kg, and the acute inhalation LD50 of the rat was> 4.7 mg / l (1h). It has strong stimulating effect on rabbit eyes and obvious stimulating effect on some human eyes. It has no teratogenic and mutagenic effects under test conditions and is highly toxic to fish.

Chlorothalonil side effects

1. Chlorhexidine has irritating effects on human skin and eyes, and a few people have allergic reactions. Can generally cause mild contact dermatitis.
2. Chlorhexidine is toxic to fish, and must be kept away from ponds, lakes and streams when applying pesticides. Do not contaminate the water source with the cleaning solution.
3. This product should be moisture-proof and sun-proof, stored in a cool and dry place. It is strictly forbidden to mix with food, seeds and feed to prevent misuse and misuse. Dispose of used containers properly and safely.
4.10% oil agent can cause phytotoxicity to peach, pear, persimmon, plum and apple young fruit.
5. It has toxic effects on silkworm, tussah, and bees. Preventive work should be done when used.
