Abstract
The present invention relates to a kind of Botanical synergistic compound pesticide and its applications, more particularly to contain matrine and pyrethroid insecticides complex composition.The Botanical synergistic compound pesticide raw material includes based on matrine and pyrethroid insecticides, and the mass percent of the matrine and pyrethroid insecticides is 40:1-1:150.The present invention is using the synergy principle between two kinds of medicaments, the shortcomings that overcoming and reduce above two medicament single dose.Prepared by the method novel botanical pesticide has the characteristics that efficient, quick, noresidue, pest are not likely to produce drug resistance and Environmental security.
Description
Technical field
The invention belongs to technical field of chemistry, it is related to a kind of Botanical synergistic compound pesticide and its application.
Background technique
With the enhancing of people's environmental consciousness, a series of safety and environmental protection hidden danger of chemical pesticide control pest and disease damage bring are increasingly
It is prominent.The future prospect of the biological control of plant pest is bright, is in urgent need.On the other hand, as people are to biological pesticide
Demand is continuously increased, and biological pesticide meets the market demand and pest and disease damage green prevention and control as a kind of effective insecticide
Effective means.Therefore, botanical pesticide can be improved crop yield, protect environment and living resources, and that realizes agricultural can
Sustainable development.
Matrine is the dry root leguminous plant kuh-seng, plant, extract in fruit made of a kind of alkaloid.Usual institute
The matrine Pesticidal products of finger actually refer to the total material extracted from kuh-seng, it is called shrubby sophora extract or is referred to as
Banlangen.Matrine can prevent and treat cabbage caterpillar, black peach aphid, prodenia litura, maize borer on tobacco, beet armyworm on vegetables,
Caterpillar, boat type caterpillar, slug moth, ruler Qu, red spider lecanium, gold are admired in striped flea-beetle, diamondback moth, Lan Yee, bradysia odoriphaga, the day on fruit tree
Tortoise, stinkbug etc., the various pests such as mythimna separata, wheat midge and locust on cereal crops have good preventive effect.Matrine
Insecticidal mechanism multiplicity, insecticidal effect is significant, to pest have tag, stomach toxicity, interior suction, food refusal, sterilization, interference peel.Effect
Mechanism is based on tagging, paralysis central nervous system, polypide protein coagulation, and polypide stomata blocks supplemented by stomach toxicity, pest death by suffocation
The bioactivity such as die.
Matrine is a kind of botanical pesticide, has the characteristics that specificity, natural sex, only generates work to specific biology
With, can be decomposed rapidly in the Nature, final product be carbon dioxide and water.Matrine botanical pesticide has been applied to cigarette
On the industrial crops such as grass, vegetables, fruit tree and tealeaves.But plant insecticide has following disadvantage outstanding, most natural products
Closing object, structure is complicated, is not easily-synthesized or synthesis cost is too high；Active constituent easily decomposes, and formulation ingredients are complicated, is not easy to standardize；Greatly
It is slow that most plants insecticide plays drug effect；Often, the residual period is short for spray；Since the distribution of plant has region, adding
The limiting factor being subject in the selection on workshop ground is mostly and the acquisition of plant has seasonality etc..
Dalmatian chrysanthemum refers to the several plant of composite family Chrysanthemum Dalmatian chrysanthemum subgenus, has natural insecticidal function, is naturally removing
On the basis of worm chrysanthemum element chemical structure basic research is clear, people start to carry out manual simulation's study on the synthesis to it, thus develop
Out it is a kind of have efficiently, wide spectrum, low toxicity and can the key properties such as biodegrade artificial synthesized insecticide -- pyrethroid kills
Worm agent.Pyrethroid is a kind of broad spectrum pesticide that can prevent and treat various pests, insecticidal toxicity than older generation insecticide if any
Machine chlorine, organic phosphorus, carbamates improve 10~100 times.Pyrethroid has strong action of contace poison to insect, some
Kind has both stomach toxicity or fumigation action, but all without systemic action.Its mechanism of action is to upset the normal physiological of insect nerve, is made
By excited, spasm to benumbing and dead.Pyrethroid is therefore safer to people and animals because dosage is small, low using concentration, to environment
Pollution very little.Its disadvantage mainly to fish toxicity height, also has injury to certain beneficial insects, and long-term reuse also results in pest
It develops drug resistance.
Summary of the invention

The present invention relates to a kind of Botanical synergistic compound pesticide and its applications, more particularly to contain matrine and quasi- deinsectization
Chrysanthemum ester insecticide complex composition.The present invention overcomes and reduces above two medicine using the synergy principle between two kinds of medicaments
The shortcomings that agent single dose.There is prepared by the method novel botanical pesticide efficient, quick, noresidue, pest to be not easy to produce
The features such as raw drug resistance and Environmental security.
Advantages of the present invention is as follows:
(1) matrine is vegetable source natural active material, can be decomposed rapidly in the Nature, final product is carbon dioxide
And water.Matrine botanical pesticide has been applied on the crops such as vegetables, fruit tree, tealeaves and tobacco, has to pest good
Preventive effect.Its preparation is less toxic to people and animals, degradable, environmentally safe, does not injure natural enemy, is conducive to the ecological balance, is suitable for organic
The control of insect of agricultural.
(2) with the Pesticidal combination of matrine and pyrethroid insecticides, both can synergy, reduce pharmaceutical use,
The type and range that pest control can be expanded again, prevention and treatment is to a variety of simultaneous evils in Crop growing stage in a drug
Worm, two kinds of substances have the function of synergy, reduce the generation of pest resistance to insecticide, reduce application cost.
(3) dosage form used by is mainly environment-friendly type soluble liquid, aqueous emulsion etc., and it is molten not use the first-class aromatic hydrocarbons of hexichol
Agent reduces the pollution to environment while reducing the murder by poisoning to operator.
(4) it can prevent and harmful organism is overcome to develop drug resistance, extend the service life of pyrethroid insecticides.
To pest mode of action multiplicity, Main Agricultural pest is removed outside main action of contace poison also have stomach toxicity, deterrent,
Food refusal inhibits growth and development isoreactivity, and mostly slow and growth and development adjustment effect, meets sustainable pest management improvement
Strategy.
Specific embodiment
Inventor has found the desinsection of matrine and pyrethroid insecticides by a large amount of formula indoor screening test
Composition mixture has synergistic function to bradysia odoriphaga, aphid, and field test results also indicate that the effect of mixture preparation better than single
The use of agent.
In order to better understand the essence of invention, technology contents of the invention are described in detail below with reference to example,
But the contents of the present invention are not so limited, and therefore cannot be interpreted as limitations on the scope of the patent of the present invention, unless otherwise indicated
Outside.Embodiment only has illustrative effect to the present invention, without the effect of any restrictions, those skilled in the art
The modification for any unsubstantiality made on the basis of the present invention, all should belong to protection scope of the present invention.
The preparation of matrine: it can be operated according to a conventional method, first crush radix sophorae raw material, the raw material of crushing
