Problems solved by technology

[0003] In addition, the random discarding of a large number of agricultural wastes today has not only caused a lot of idle and waste of resources, but also caused a certain burden on the environment. Some economic value and social value, to achieve sustainable development, is the direction of today's agricultural development

Abstract

The invention discloses a plant-based miticide as well as a preparation method and application. The plant-based miticide is prepared from 40 to 80 weight percent of bulk drug and 20 to 60 weight percent of conventional ingredients, wherein the bulk drug comprises the components in percentage by weight: 5 to 40 percent of capsicum annuum extract, 2 to 40 percent of lycopersicon esculentum extract,5 to 30 percent of arachis hypogaea extract and 2 to 30 percent of glycine max extract. The plant extracts are obtained by drying and grinding the cut plant and the waste root, branch, stem and leavesor mixture thereof after fruit harvesting into powder, extracting and filtering. According to the plant-based miticide, the agricultural wastes are used as main material source, the plant-based miticide is compounded by the plant extracted, has higher preventing effect on the tetranychus cinnabarinus, directly can be used for preventing the tetranychus cinnabarinus, and has the features of high efficiency, no residue, low product cost and environment-friendly effect and excellent comprehensive performance.

Description

technical field [0001] The invention relates to a botanical acaricide in the technical field of pesticides, in particular to a botanical acaricide for preventing and treating Tetranychus cinnabarinus, a preparation method and application. Background technique [0002] Tetranychus cinnabarinus is a large agricultural and forestry pest widely distributed in temperate regions of the world. It has the characteristics of fast reproduction, strong adaptability, high mutation rate, wide host range, and easy to develop drug resistance. It is recognized as one of the most difficult pests to control. . At present, the amount of acaricides used in the world is second only to the amount used to control Lepidoptera and Hemiptera pests. Most of them are organic or inorganic chemical acaricides, which have great environmental pollution, long residual period, and are harmful to higher animals and animals. Natural enemies are toxic. Therefore, it is very urgent to find substances with acar...
