Embodiment 1

[0021] Control percentage of Tetranychus cinnabarinus aqueous solution: 10% of Radix Radix Radix Root Extract, 15% of Radix Radix Radix Radix Stem Extract, 15% of Radix Radix Radix Radix Leaf Extract and 60% of distilled water.

[0022] Dry the roots, stems, and leaves of the Radix Glycyrrhiza at 30-50°C and grind them into powders. Weigh 20g each of the root, stem, and leaf powder (20-40 mesh particles) of the Radix Radix Radix, and use 800ml of 70% ethanol solution at room temperature. Immerse for 1-3 days, filter, vacuum the crude extract obtained after leaching to -0.1 atmospheric pressure and place it in a water bath at 40-80°C to concentrate the crude extract into an extract, add distilled water, and place Suspend the dry matter in an ultrasonic generator for 10-15 minutes, and prepare the acaricide for Dijin plant. Water is added thereto under a stirring environment of 30-50°C, diluted to a concentration of 3wt%, and then cooled to normal temperature to form an aqueous ...

Abstract

The invention discloses plant acaricide of Japanese creeper and a preparation method and application thereof. The plant acaricide of Japanese creeper stem and root comprises, by weight percent, 10-40% of extract of Japanese creeper root, 10-40% of extract of Japanese creeper stem, 5-35% of extract of Japanese creeper leaf, and 20-60% of distilled water. The extract of the Japanese creeper root, the extract of the Japanese creeper stem and the extract of the Japanese creeper leaf are respectively made by grinding root, stem and leaf of the Japanese creeper into powders and subjecting the powders to concentration under reduced pressure. The plant acaricide of Japanese creeper has high control effect on carmine spider mite, can be used to control the carmine spider mite directly and is pollution-free and free of residual toxicity, and hazards of chemical pesticide are avoided.

Description

technical field [0001] The invention relates to a preparation method in the technical field of pesticides, in particular to a preparation for controlling Tetranychus cinnabarinus by using the extract of Radix chinensis and its preparation method and application. Background technique [0002] Herbivorous mites have the characteristics of small size, rapid reproduction, high population density, and serious damage. They are recognized as harmful biological communities that are difficult to control. Tetranychus cinnabarinu (Tetranychus cinnabarinu) belongs to Arachnida, Eucaridae, and Tetranychidae. It is an important harmful mite that harms fruits, vegetables and greenhouse plants. Chemical pesticides play an important role in controlling harmful mites in agricultural production, protecting crops from damage and ensuring agricultural economic value. However, due to the long-term and extensive use of chemical pesticides, a series of negative effects have been produced, such as ...
