Abstract

The invention discloses a botanical insecticide for ginger, and further provides a preparation method of the botanical insecticide for the ginger. The botanical insecticide is prepared from the raw materials in parts by weight: illicium anisatum leaves, tobacco stems, willow-leaved smartweed juice, wild pepper, pine needles, cortex meliae, ailanthus altissima leaves, a surfactant and an anti-oxidant. The preparation method comprises the following steps that the tobacco stems, the wild pepper, the pine needles, the cortex meliae, the illicium anisatum leaves and the ailanthus altissima leaves are dried and crushed to prepare a pre-prepared material; the pre-prepared material is added to a solvent, and after heating and ultrasonic extraction, filtration is performed to extract filtrate to obtain an extracting solution; and the extracting solution is added to the willow-leaved smartweed juice, the surfactant and the antioxidant are added to the extracting solution, uniform stirring is performed, and the botanical insecticide for the ginger is obtained by concentration. The active ingredients of alkaloids, ketones and organic elements of the botanical insecticide are high-efficiency, low-toxic and environmentally friendly, and the use requirements of the ginger can be met.

Description

technical field [0001] The invention relates to the technical field of insecticides, in particular to a botanical insecticide for ginger and a preparation method thereof. Background technique [0002] At present, the control of ginger pests is still dominated by chemical control, which can easily cause problems such as pesticide residues in fruits, insect resistance, and ecological environment pollution, which cannot meet the needs of the population. Botanical insecticides are the active ingredients extracted from plants with special insecticidal effects, which are dissolved by adding auxiliary agents. They are recognized worldwide as broad-spectrum, high-efficiency, low-toxic, easy-to-degrade, non-residual insecticides, and have no antibiotic resistance. It has medicinal properties and has the effect of repelling and killing most plant pests without any pollution to humans, animals and the surrounding environment. Therefore, how to prepare a plant-derived insecticide for g...
