Usage

Uses

Used in Agricultural Industry:
PYRIMINOBAC-METHYL (E) is used as a herbicidal agent for the purpose of controlling grass weeds in cereal crops. Its selective action targets the ALS enzyme in weeds, thereby preventing their growth and ensuring the healthy development of the cereal crops. The low toxicity profile of PYRIMINOBAC-METHYL (E) contributes to its safety for use around mammals, birds, and aquatic life, making it an environmentally considerate choice for weed control. It is crucial, however, to adhere to the label instructions and safety guidelines to mitigate any potential environmental or health risks associated with its application.

Method for synthesizing herbicide pyriminobac-methyl in paddy field

The invention belongs to the field of fine chemical engineering, and particularly relates to a preparation method of herbicide pyriminobac-methyl for a paddy fields. The preparation method comprises the following steps: synthesizing 3-hydroxy phthalic anhydride by using 3-chlorophthalic anhydride as a new raw material, protecting carbonyl by using diethyl malonate, hydrolyzing to obtain 2-acetyl-6-hydroxy benzoic acid, and esterifying to obtain 2-acetyl-6-hydroxy methyl benzoate; then carrying out imidization reaction with methoxyamine hydrochloride to obtain 2-hydroxy-6-(1-methoxy iminoethyl-methyl)-benzoate, and finally, condensing with 2-tosyl-4, 6-dimethoxypyrimidine to obtain pyriminobac-methyl. In the process of preparing pyriminobac-methyl, high-risk reagents such as n-butyllithiumare avoided, a large amount of wastewater generated by diazotization is avoided, the income is increased, and the environment is protected.

Agrochemical formulations for water surface application

New agrochemical formulations for application to the water of paddy fields, which formulations comprise A) at least one solid core material having an apparent specific density of less than 1 and a particle diameter within the range from about 300 μm to about 1,400 μm, and B) a coating layer comprising at least one biologically active compound, at least one substance having the ability to reduce the interfacial tension between water and air, at least one oily substance and, if appropriate, one or more additives, and the use of such agrochemical formulations for applying biologically active compounds to the water of paddy fields.
