Problems solved by technology

[0004] Although the toxicity of diquat is far lower than that of paraquat, there is no effective antidote for diquat. Therefore, once the poisoning of diquat is accidentally swallowed or swallowed intentionally, without timely and correct rescue treatment, the Can cause serious injury or even death to people or animals

Embodiment 1

[0026] Table 1

[0027]

[0028]

[0029] The active ingredient in the soluble colloid is based on diquat cation, and the concentration is 2.68%. The viscosity of the soluble colloid (25°C, measured by a rotational viscometer) is 25000mPa.s. It is still stable after storage for 14 days, and the dilution stability of the soluble colloid is qualified (the method refers to the national standard GB19308-2003 for paraquat aqueous solution), and the water-soluble speed is relatively fast, and it is completely dissolved within 45 seconds (at 25 ° C, the concentration of the preparation in 100 times of water is measured). time required for complete dissolution).

Embodiment 2

[0031] Table 2

[0032]

[0033] The active ingredient in the soluble colloid is based on diquat cation, and the concentration is 5.35%. The viscosity of the soluble colloid (measured by a rotational viscometer at 25° C.) is 43000 mPas. It is stored cold at 0° C. for 7 days and stored hot at 54° C. for 14 days. Still stable, the dilution stability of the soluble colloid is qualified (the method refers to the national standard GB19308-2003 of paraquat aqueous solution), the water-soluble speed is fast, and it is completely dissolved in 55 seconds (at 25 ° C, the total dissolution of the preparation in 100 times of water is determined) time required).

Embodiment 3

[0035] table 3

[0036]

[0037] The active ingredient in the soluble colloid is based on the diquat cation, and the concentration is 8%. The viscosity (25° C.) of the soluble colloid is 36000 mPas. It is still stable after cold storage at 0° C. The dilution stability of the sol agent is qualified (the method refers to the national standard GB19308‐2003 for paraquat aqueous solution), and the water dissolution rate is relatively fast, and it is completely dissolved within 45s (at 25°C, the time required for the complete dissolution of the preparation in 100 times of water is measured).

Abstract

The invention belongs to the technical field of pesticides, and relates to an aquacide soluble colloidal solvent. The aquacide soluble colloidal solvent contains the following components in percentage by weight: 1%-40% of aquacide dibromide, 0.54%-21.42% of reduced aquacide cations, 5%-30% of surface active agents, safe auxiliary components, namely vomitives, warning coloration, odor agents, bittering agents and the like, and the balance of water. According to the invention, the aquacide is processed into the soluble colloidal solvent, so that an aquacide preparation is effectively reduced, so that the skin of human or animals is prevented from being burnt by being splashed, and the safety risk of the aquacide is outstandingly lowered due to low high-level flowability and small mistaken or impulsive swallowing quantity of the aquacide soluble colloidal solvent.

Description

technical field [0001] The invention belongs to the technical field of pesticides and relates to a diquat soluble colloid. technical background [0002] Diquat, a quick-acting contact-killing bipyridine herbicide, is one of the most widely used herbicides in the world. Its global sales and usage are second only to glyphosate and paraquat, ranking No. The third largest total herbicide. [0003] Paraquat has been banned or restricted in the European Union and other places due to its toxicity. As a herbicide product with the same mechanism and mode of action as paraquat, diquat has been rapidly promoted and used, gradually filling the market vacated by paraquat . [0004] Although the toxicity of diquat is far lower than that of paraquat, there is no effective antidote for diquat. Therefore, once the poisoning of diquat is accidentally swallowed or swallowed intentionally, without timely and correct rescue treatment, the Can cause serious injury or even death to people or an...
