Abstract

The invention discloses a preparation process of organic pesticide, and relates to the field of agricultural pesticide preparation. The preparation process is prepared from the following raw materials in parts by weight: 25 to 40 parts of felon herb, 20 to 35 parts of pepper leaves, 15 to 25 parts of bunge pricklyash leaves, 10 to 18 parts of cortex cinnamomi, 5 to 12 parts of camenthol, 2 to 5 parts of perilla leaves, 8 to 16 parts of orange peels, 5 to 8 parts of strophanthus divaricatus and 5 to 9 parts of tuba roots. The preparation process of organic pesticide provided by the invention has the advantages that the insect-resistant spectrum is wide; the raw materials are natural, and achieves the environment-friendly effect; after application, no harm is caused on the human body and environment; the organic pesticide can be widely applied to the planting of nuisanceless plants; the preparation method is simple; the industrialization is easily realized.

Description

A kind of preparation technology of organic agricultural chemicals

Technical field

The present invention relates to agricultural medication and manufacture field, be specifically related to the preparation technology of a kind of organic agricultural chemicals.

Background technology

nullIn agricultural production，Insect can disturb the growth of crops，Both have impact on the yield of crops，Also food safety is caused puzzlement，Therefore，Most peasants can select chemical pesticide to carry out pest control，But in recent years，The problem caused due to abuse chemical pesticide is increasingly subject to pay attention to，First，Abuse chemical pesticide can make the Drug resistance of insect increase，It is reported that，Conventional pesticide effective dose 10 years is general rises three times，So on，Insect pasts medical help and not paints an alarming picture of the situation just to scare the audience，Secondly，Although chemical pesticide use the yield that improve crops，But difficulty dispelled by the chemical pesticide of residual，Healthy to people causes the biggest threat，Finally，After unnecessary chemical pesticide flows into river，Can severe contamination water quality，Not only can not drink，Also can form algae to spread unchecked，The disastrous effect of disruption of ecological balance，Therefore，Seek Novel high-efficient pesticide extremely urgent，Natural organic agricultural chemicals is the natural pesticide being transformed by agricultural products，Both the agricultural resource of plantation can have been made full use of，Also the health of human body and environment will not be impacted，Putting forth effort to develop natural organic agricultural chemicals is a main trend.

Summary of the invention

Instant invention overcomes above-mentioned shortcoming, and the preparation technology of a kind of organic agricultural chemicals is provided.
