Abstract
The invention discloses a plant source insecticide, the effective components comprise the following raw materials by weight percentage: 7% to 9% of fructus Carpesii, 26% to 29% of fructus toosendan, 13% to 16% of quisqualis, 26% to 29% of hairyvein agrimony, 11% to 16% of levisticum, 3% to 5% of polygonum aviculare and 3% to 6% of alum, wherein the sum of the weight percentage of the raw materials is 100%. The invention has the advantages of rapid insect killing, wide insecticidal spectrum, substantial effect and no environmental pollution.
Description
Technical field
The invention belongs to agricultural insecticide technical field, be specifically related to a kind of plant insecticide, also relate to preparation method, using method and the purposes of this plant insecticide.
Background technology
Liu Tong insecticide has chemical insecticide and environment-friendly pesticide two big classes in the market.The main path that various insecticide active ingredients enter in the pest body has three: one, infiltrates through in the pest body by epidermis and intersegmental membrane: the 2nd, infiltrate through in the pest body by pore: and the 3rd, enter in the pest body by feed.
The effect of chemical insecticide infiltration insect epidermis, intersegmental membrane is stronger, and it is fast to play a role in pest body, and desinsection is rapid.But some insect has produced drug resistance in various degree to it, and contaminated environment, and this is two problems that can not be ignored that present chemical insecticide exists.
Environment-friendly pesticide comprises microorganism insecticide and plant insecticide two classes.The microorganism condition of culture of microorganism insecticide is strict, the production cost height, and the operating technology complexity, the user is difficult to be grasped, and has influenced promoting the use of of microorganism insecticide.Plant insecticide is free from environmental pollution, and people and animals are not had harm, and pest resistance is low, and raw material sources are extensive, and low price is easy and simple to handle, and the user more easily grasps.But a little less than existing plant insecticide infiltration insect epidermis, the intersegmental membrane effect, desinsection speed is slow.Oxidative degradation takes place in plant insecticide easily that sell in the market, circulate simultaneously, causes the active ingredient quality to descend, and has further weakened the insecticidal effect of plant insecticide.More than all multifactor uses that restricts plant insecticide.
Summary of the invention
The purpose of this invention is to provide a kind of plant insecticide, its kill pests is rapid, and insecticidal spectrum is wide, and insecticidal effect is remarkable, has overcome existing plant insecticide desinsection speed slowly and the shortcoming of insecticidal effect difference.
The present invention also aims to, preparation method, using method and the purposes of this plant insecticide is provided.
First kind of technical scheme of the present invention is, a kind of plant insecticide, its raw materials of effective components percentage by weight consists of: Lappula echinata 7%～9%, Fructus meliae toosendan 26%～29%, the fruit of Rangoon creeper 13%～16%, hairyvein agrimony 26%～29%, levisticum 11%～16% pivot holds 3%～5%, alum 3%～6%, more than the percentage by weight sum of each component be 100%.Pivot holds, and is also referred to as Armstrong.
