Abstract

The invention relates to botanical herbicide powder and a preparation method thereof, and belongs to the technical field of herbicide processing. The botanical herbicide powder is prepared from the following components in parts by weight: 15 to 20 parts of soapberry testa extract, 10 to 15 parts of sphenoclea zeylanica extract, 10 to 15 parts of fragrant eupatorium herb extracting solution, 5 to 8 parts of tween-80 and 50 to 55 parts of maltodextrin. The preparation method comprises the following steps: mixing the components in proportion, stirring for 30 to 35 minutes and then homogenizing for 25 to 30 minutes under the condition of 300MPa to 350MPa so as to obtain a lactescence; and performing spray drying treatment on the lactescence by controlling spray drying conditions that the inlet air temperature ranges from 165 DEG C to 163 DEG C, the exhaust temperature ranges from 98 DEG C to 101 DEG C, the pumping speed ranges from 8.0mL / min to 8.5mL / min, the exhaust pressure ranges from 100Pa to 150Pa and the inlet air quantity ranges from 1050L / h to 1055L / h, namely, obtaining the botanical herbicide powder. The botanical herbicide powder has the good water solubility and can be used independently or compounded with other herbicides. The botanical herbicide powder has the advantages of being efficient, environment-friendly and difficult to generate resistibility.

Description

technical field [0001] The invention relates to a herbicide, in particular to a botanical herbicide powder and a preparation method thereof, belonging to the technical field of herbicide processing. Background technique [0002] In the late 1940s, chemically synthesized pesticides were favored due to their high efficiency, quick effect, and broad insecticidal spectrum, which caused the research and use of botanical pesticides to fall into a trough. However, with the use of chemical pesticides, its disadvantages have gradually emerged, such as the "3R" problem (residue, drug resistance, and re-emergence of pests). Botanical pesticides have attracted people's attention again because of their high efficiency, low toxicity, low residue, high selectivity, and resistance to pests, and have become a hot spot in current pesticide research. Due to the low toxicity of botanical pesticides to humans and animals, they are easily degraded in the environment and basically have no obvious...
