Description
Technical field
The present invention relates to biological pesticide technical field, more particularly, to a kind of medicine based on herbs of preventing and treating storage pest and its
Preparation method.
Background technology
Grain is in storage, it may appear that a lot of storage pests, such as sitophilus zea-mais, lesser grain borer, red flour beetle, Callosobruchus chinensis, wheat
Pretty young woman and rice weevil etc., these insects are small, and reproductive capacity is strong, and harm is very big, and such as grain storage pest can increase injured kernel, make grain grain
Rupture, crush, eat hollow, so as to cause grain to be lost during storage in a large number；Reduce germination percentage, damage agricultural production；Cause
Grain generates heat, goes mouldy；In addition insect secretion, excrement can also pollute grain, affect health, these situations cause sternly
The economic loss of weight, therefore the preventing and treating to storage pest is very urgent.And the medicament of commonly used preventing and treating storage pest is main
There are the compounds such as oxirane, hydrogen phosphide and bromine potassium alkane and the chemical pesticide based on machine phosphorus and pyrethroid pesticide.
Chemical agent is used in a large number for a long time, and use single varieties, so that insect produces the very big resistance to the action of a drug, cause application dosage
More and more higher, makes the preventing and treating of storage pest become more difficult.In addition chemical pesticide toxicity is big, and residual is high, and human body can be affected to be good for
Health, therefore develops the medicine based on herbs of green, the preventing and treating storage pest of environmental protection to the lifting of stored grain quality and storage pest
Preventing and treating has great importance.

（4）It is 1.5g/ pieces by granule compressing tablet, specification, that is, prepares product.
The stifling test of storage pest
Take 5000mL transparent vessels, wheat is placed in bottom, per bottle moves into 100 for examination insects, respectively with sitophilus zea-mais, lesser grain borer, red
Plan ostomatid and Callosobruchus chinensis are conducted batch-wise test as examination insect is supplied, every kind of for examination insect test 100.By embodiment 1-8 with
And 1 medicine based on herbs for preventing and treating storage pest prepared by comparative example 1-5 is placed in wheat, container closure, test is heavy every time
Multiple 3 times, be placed in the incubator that temperature is 26 ± 1 DEG C, dead borer population and borer population living is observed and is recorded after one week, writing brush is wherein used
Polypide is stirred, polypide is motionless to be death, and calculates the death rate；Not place the medicine based on herbs of preventing and treating storage pest in wheat
As a control group, corrected mortality is calculated, as a result as shown in table 1.In addition, for the term of validity length for verifying product of the present invention,
After product sealing prepared by the embodiment of the present invention 4 and embodiment 5 is placed 2 years, the stifling test of above-mentioned storage pest is carried out, with
The medicine based on herbs of preventing and treating storage pest is not placed in wheat as a control group, and result of the test is shown in Table 2.
The wherein death rate（%）=dead borer population/total borer population × 100%
Corrected mortality（%）=（Process the death rate-control death rate）/（1- compares the death rate）×100%
1 storage pest of table fumigates test data
2 term of validity test data of table
As can be seen from Table 1, the medicine based on herbs of the preventing and treating storage pest for preparing in embodiment of the present invention 1-8 is to sitophilus zea-mais, paddy
, in 90%-98%, the wherein insecticidal effect to red flour beetle is the most notable for the corrected mortality of moth-eaten, red flour beetle and Callosobruchus chinensis,
Good disinsection effect, noresidue, and as can be seen from Table 2, after placing 2 years, the product of embodiment 4 is to sitophilus zea-mais, lesser grain borer, red
Intend corrected mortality >=86% of ostomatid and Callosobruchus chinensis, illustrate that keeping life limit is long.
Embodiment 5 is substantially the same manner as Example 4, and difference is to include active component using beta-schardinger dextrin,
Then piece agent prepared, but the insecticidal effect indifference of embodiment 5 and embodiment 4, illustrate using beta-schardinger dextrin to killing
The active component of worm effect is included, and does not affect the insecticidal activity of medicament.In addition as can be seen from Table 2, embodiment 5 after 2 years
Product to the corrected mortality of insect higher than embodiment 4, illustrate that the inclusion of beta-schardinger dextrin has slow releasing function, can greatly prolong
The term of validity of medicament.
Respectively the raw material for preparing the medicine based on herbs of preventing and treating storage pest is adjusted in comparative example 1-4, to part
Raw material is replaced, but raw material total amount keeps constant, but the insecticidal effect of comparative example 1-4 is compared with Example 4, and desinsection is imitated
Really poor, illustrate that there is the various raw materials in the present invention synergy, lacking for any raw material can all affect killing for product
Worm effect.
In addition comparative example 5 is to have adjusted in preparation method with the difference of embodiment 4, only with ultrasonic wave extraction
Method, insecticidal effect are also poor than embodiment 4, illustrate that the extracting method of the present invention can increase the recovery rate of active component, and raising is killed
Worm effect.
Finally illustrate, only in order to technical scheme to be described and unrestricted, this area is common for above example
Other modifications or equivalent that technical staff is made to technical scheme, without departing from technical solution of the present invention
Spirit and scope, all should cover in the middle of scope of the presently claimed invention.
