Description
Technical field
The present invention relates to technical field of pest control, and in particular to a kind of new material of environment-friendly type pest control and its preparation
Method.
Background technique
Caste is various, comes in every shape, and belongs to the arthropod in invertebrate, and being that quantity is most on the earth moves
Object group accounts in all biological species (including bacterium, fungi, virus) more than 50%, their trace almost spreads over generation
Each corner on boundary.At the beginning of 21 century, insect known to the mankind has more than 100 ten thousand kinds, but still waits to find there are many type.
Insect most species in the animal kingdom, quantity is maximum, causes significant impact to agricultural production and human health.
In agricultural production, can have an adverse effect to the production of crop there are many insect, for example, locust, aphid, aleyrodid,
Thrips, snout moth's larva, diamond-back moth etc..
Dalmatian chrysanthemum with efficient, less toxic, low-residual characteristic be considered as in the world most safe, most effective natural plants kill
Worm agent.Having 9 kinds in 12 kinds of biological insecticides that related organization, the United Nations in 1992 is recommended is pyrethrins or quasi- pyrethroids class chemical combination
Object, but since quasi- pyrethrin pesticide pollutes in production, moral, Fa Dengguo have been prohibited in its domestic production.Chinese agriculture
In industry portion " green food " standard promulgated in 2000, natural insecticide pyrethrins comes the first place for requiring to use pesticide.
Pyrethrum insecticide pharmacological property is strong, quick, lasting medicine, will not cause drug resistance, is ant fly, bee dung beetle, aphid etc.
The deadly enemy of numerous software pests, while being also the jinx of a variety of virus and bacterias.The insecticide made of pyrethrins can be used extensively
In farmland, silo, food processing factory, hospital and family, in addition to this Dalmatian chrysanthemum can be also used for war industry, timber, industry,
The fields such as container, transport service, construction industry.Mainly there are three classes in the case where pyrethrins insecticide makes insect be poisoned to death: weight
The generation for leading to a kind of neurotoxin is put after multiple；Comprehensive destruction of nervous system, conduction block；Other lesion tissues, such as dehydration
And tissue necrosis etc..
Application No. is the Chinese patents of CN 201510590146.0 to disclose a kind of diatomaceous earth and preparation method thereof
And purposes, the diatomaceous earth include following component by mass percentage: diatomite in powder 80-91%；Perian insect powder 1.5-
3.5%；Sepiolite powder 7.5-16.5%.The insecticide ingredient is simple, insecticide efficiency is high, safety and low toxicity, low-residual, is a kind of ring
Border friendly natural botanical insecticide, the insecticide have extremely strong lethality to soft-bodied insects, can be widely used for grain and kind
The prevention and control of plant diseases, pest control in terms of the storage of son, crops melon and fruit, vegetables and food production, and the insecticide preparation method is simple,
It is suitable for industrialized production.But its persistence of the insecticide is short of, and is unable to long term in the prevention and treatment of pest.
Summary of the invention
The purpose of the present invention is to provide a kind of new materials and preparation method thereof of environment-friendly type pest control, are prepared
It not only can effectively kill the pest for contacting the material in the short time new material of prevention and treatment insect, and smell can effectively drive
It gets rid of insects, pest control effect is good, while had good sustained release effect, and permanently effective, and each substance is easily obtained and will not make to environment
It is environmentally protective at pollution.
