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.

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.

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.

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

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.

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.

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.

The Chlorothalonil Test For Agricultural Products kit offered by BALLYA can effectively detect the presence of chlorothalonil in agricultural products.
This kit is easy to operate, and has a short test time and high accuracy. The test results comply with EU standards, which can effectively ensure the safety of agricultural products.
