Description
Technical field
The present invention relates to field of pesticides, more particularly, to a kind of insecticide for green soy bean and preparation method thereof.
Background technology
With the development of modern science technology, chemical pesticide is because its adaptation is wide, and easy to operate, cost is low, significant effect
The advantages that be widely used.But since the desinsection specificity of chemical pesticide is not strong, the field longevity of residure is longer, while easily induce
Pest develops immunity to drugs it, particularly pollution of the chemical residue pesticide to agricultural product and environment, causes women's miscarriage, baby abnormal
Shape and the disease such as various cancers of the mankind is induced, therefore the attention of the mankind is increasingly subject to using biological pesticide pest control.Biology
Pesticide mainly includes microbial pesticide, botanical pesticide and animal pesticide etc..It is raw for conventional chemical pesticide
Thing pesticide has the mode of action unique, prevents that object is single-minded, and to the beneficial organisms such as natural enemy safety, dosage is small, and degraded is fast, to people,
Poultry, environmental risks are low, the features such as especially suitable for disease, worm, crop smothering integrated control.The increasing realized with human environment protection
By force, the biological pesticide of high-efficiency low-toxicity has become the developing direction of current pesticide.
The content of the invention
It is an object of the present invention to providing a kind of quick desinsection of energy, and the desinsection lasting period is grown, free from environmental pollution, right
Crop has growth promoting function, and to safety of human and livestock, long-time service pest is not likely to produce the insecticide for green soy bean of resistance.
The second object of the present invention is to provide that a kind of preparation process is simple, the desinsection for green soy bean of low production cost
The preparation method of agent.
The present invention is directed to the problem of being mentioned in background technology, and the technical solution taken is：For the insecticide of green soy bean, component
And its parts by weight for 8 ~ 15 parts of bacillus thruingensis powder, 8 ~ 15 parts of neem seed, 1 ~ 3 part of synergist, 1 ~ 3 part of the tuber of stemona, 1 ~ 3 part of fragrant eupatorium herb,
3 ~ 6 parts of Eupatorium adenophorum.Synergist is 40 ~ 60% hemp oils and 40 ~ 60% organic silicon surfactants.
Hemp oil extracting method is：By the fresh ramie plant shearing of collection, crush, cross 20-80 mesh sieves, take ramie to plant
Strain powder, adds acetone, stirring and leaching 5-9h, centrifuges, be concentrated under reduced pressure to obtain hemp oil.
For the method for producing insecticide of green soy bean, comprise the following steps：
1）Pretreatment：Steam blasting is carried out after neem seed is carried out pre-preg, pressure is controlled in 3.0 ~ 4.0MPa, maintenance
Between be 40 ~ 70s, obtain neem seed explosion thing；Petroleum ether extraction is added, layering takes phase, obtains neem seed extract；
2）Fermentation：0.5 ~ 0.6g/L peptones 0.7 are added in formula ratio Stemona Root, fragrant eupatorium herb powder and Eupatorium adenophorum powder
~ 1.6mg/L Beta-alanines, are inoculated with cellulase producing strain, in 22 ~ 28 DEG C, initial pH5.0 ~ 7.0,100 ~ 200r/min shake
Bottle 60 ~ 84h of fermented and cultured, high speed centrifugation take zymotic fluid.Above-mentioned cellulase producing strain is Wei Jiao, Wan Xuerui, Wu Run, waits
Separation screening and optimization culture conditions [J] Gansu the agricultural university journal of cellulase-producing fungi bacterial strain, 2016,51 (2):8-
Aspergillus fumigatus bacterial strain B-2-3 in 15..Above-mentioned cellulase producing strain produces substantial amounts of cellulase during fermentation, can be by hundred
Cellulase hydrolysis on portion, fragrant eupatorium herb and Eupatorium adenophorum cell membrane, active ingredient dissolution.The hair obtained using above-mentioned fermentation operation
Zymotic fluid is better than the enzymolysis liquid directly obtained with the cellulase degradation tuber of stemona, fragrant eupatorium herb and Eupatorium adenophorum to the lethality of pest,
But the specific mechanism of action is still not clear；
3）It is prepared by finished product：Neem seed extract, formula ratio bacillus thruingensis powder and synergist are added in zymotic fluid, after stirring evenly
The 1/6 ~ 1/4 of original volume is concentrated into, obtains the insecticide of microbial fermentation preparation.There are obvious phase for each component in the present invention
Mutual coordinative role, the end product properties being prepared are stablized, long shelf-life；After sprinkling, high in the wetability of crop surface, drug effect is held
The effect phase is grown；It directly acts on the fat-body of insect larvae and midgut epithelial cells core, and replicate causes larva to catch an illness death rapidly, together
When epidemic disease can be triggered in population by laterally infection, infected by longitudinal direction and kill pupa and ovum, effectively control pest population
And its harm.Different from the insecticide of microbial source, killing speed of the present invention to pest is rapid, since the dead worm that sprays to
Half a day is needed to the time.
Neem seed obtains pre-preg：Commercially available neem seed is taken, removes impurity, is crushed, crosses 15-20 mesh sieves, adds 15-
20 parts of distilled water, stir 30-35min, sealing and standing 6-10h.Pre-preg adds the humidity of neem seed, and material is fully molten
Swollen, the osmotic efficiency of steam when improving steam treatment, improves demolition effect, promotes the release of nimbin, make plant resources
It is fully used.
The addition of petroleum ether is 0.7 ~ 1.5 times of the distilled water volume added during explosion.Nimbin is liposoluble substance,
And its solubility in petroleum ether is high, uses petroleum ether as extractant, while enrichment, the damage of nimbin can be greatly reduced
Lose.
Compared with prior art, the advantage of the invention is that：In the present invention there is obvious mutually coordinated effect in each component,
The end product properties being prepared are stablized, long shelf-life；It is high in the wetability of crop surface after sprinkling, drug effect lasting period length；Its is straight
Connect the fat-body for acting on insect larvae and midgut epithelial cells core, and replicate causes larva to catch an illness death rapidly, while can pass through
Laterally infect and trigger epidemic disease in population, infected by longitudinal direction and kill pupa and ovum, effectively control pest population and its harm.No
The insecticide of microbial source is same as, killing speed of the present invention to pest is rapid, and half a day is only needed to one since the dead worm that sprays to
Its time.
