Biogenic pesticide containing xanthoxylin and abamectin and preparation method thereof

Abstract

The invention discloses a biogenic pesticide containing xanthoxylin and abamectin and a preparation method thereof. The biogenic pesticide is used for killing insects; and the biogenic pesticide containing the xanthoxylin and the abamectin is formed from the following components in parts by weight: 0.01-12.9 parts of the xanthoxylin, 0.1-10 parts of the abamectin, 0.5-5 parts of a synergist, 0.1-5 parts of a sterilizing agent, 1-20 parts of an emulsifying agent, 1-30 parts of plant oil, 1-8 parts of an anti-freezing agent, 0.1-2 parts of a thickening agent and 20-70 parts of water. According to the biogenic pesticide disclosed by the invention, any chemical solvent does not need to be added into effective components of the biogenic pesticide; the water-based preparation can be widely applied to prevention and treatment of insect pests of places with relatively concentrated people, such as parks, green lands, streets, and family gardens; and the biogenic pesticide is also applicable to the prevention and the treatment of fowl and livestock fur injurious insects. A production process of the xanthoxylin does not use an organic solvent; and extracted pepper fruit waste dregs are composted and fermented and are returned back to fields to be used as a base fertilizer to be applied. In the whole product production process, the energy consumption is low, and equipment investment is small and the occupying area is small; and sources of raw and auxiliary materials are wide and are easy to obtain.

Description

technical field [0001] The invention relates to the technical field of biological source pesticides, in particular to a biological source pesticide containing xanthanin and abamectin and a preparation method thereof. Background technique [0002] Pesticides play an important role in the control of pests and diseases in agricultural production. However, many pesticides are toxic to the human body, and the pesticides lost to the soil or the air cause serious environmental pollution. For this reason, a large number of highly toxic chemical pesticides have been banned, and many pesticide formulations also produce many environmental pollutants during processing. It is unfriendly to operators and the environment during application, such as emulsifiable concentrate and wettable powder, etc. will also be phased out; with the acceleration of urbanization, parks and green spaces and home gardening continue to increase, and to solve the problem of pesticide application safety in public...

AI Technical Summary

Problems solved by technology

However, there are following disadvantages in the existing biogenic insecticides produced by Xanthoxylin: when Xanthoxylin is used to prepare insecticidal products, most of them are emulsifiable concentrate preparations, which have a greater impact on the human body and serious environmental pollution when used; Abamectin insecticides are mostly single-dose or simple compound preparations, resulting in poor stability of insecticidal efficacy and great influence by the environment; and most of the avermectins on the market are single-dose or compounded with chemical pesticides. A certain amount of resistance has been developed, and in order to achieve the control effect, the dosage is also increasing

In addition, at present, many manufacturers adopt the method of organic solvent extraction when preparing xanthoxylin, such as the preparation method of xanthoxylin insecticide announced in Chinese patent CN200410021715. In prime time, the fruit and / or leaves of Zanthoxylum bungeanum are crushed, soaked in one or several mixtures of methanol, ethanol, formaldehyde, and mixed alcohols, then extracted with acetone, butylene glycol ester, dioctyl ester, etc., and extracted with organic solvents More volatile harmful substances will be produced, which will pollute the environment. Due to the large amount of residual organic solvents in the fruit waste residue, the fruit waste residue is also difficult to handle, and other single extraction methods also make the extraction utilization rate of xanthanin very low, resulting in extreme big waste
