Abstract

The invention discloses a pesticide preparation containing plant vinegar liquid, wherein the ingredients include plant vinegar liquid 1-99%, conventional pesticides 0.1-90.0%.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to a pesticide preparation containing vegetable vinegar liquid. Background technique [0002] Vegetable vinegar liquid is a brown liquid product condensed at room temperature from the gas collected after pyrolysis of plant materials and their processing residues. It contains organic acids, phenols, ketones, aldehydes, alcohols and heterocyclics, etc. More than 300 ingredients. At present, bamboo vinegar, wood vinegar and grass vinegar are mainly used. The definition of "vegetable vinegar" in the present invention includes bamboo vinegar (a by-product obtained through high-temperature pyrolysis of bamboo processing residues), wood vinegar (a by-product obtained through high-temperature pyrolysis of wood processing residues) ) and grass vinegar liquid (referring to the by-products obtained by high-temperature pyrolysis of herbs and crop straws). Abroad, the resear...
