Description
Technical field
The invention belongs to novel pesticide research and development technology fields, and in particular to a kind of Pesticidal combination containing jervine.
Background technology
Mite class also known as red spider, white spider etc. belong to Arthropoda Arachnoidea.In the mite of crop of agriculturally mainly causing harm
Class mainly has the tetranychids such as Panonychus citri, Tetranychus cinnabarinus, Tetranychus urticae and goitre mite, rust mite etc..The mite class of these crops of causing harm usually has
There is egg laying amount big, reproduction speed is fast, and population density is big, and generation overlap is apparent, the features such as being also easy to produce drug resistance.Typically result in fruit
Flower skin, leaf chlorosis deformation, fruit tree nutrition is bad, fallen flowers finally occurs, falls leaves, falls the destructive consequence such as fruit.
Jervine is the active material extracted from the rhizome of Veratrum herbaceos perennial black false hellebore, have it is nuisanceless,
The features such as pollution-free, without residual hazard is efficient, less toxic, broad spectrum pesticide of new generation.The main insecticidal action mechanism of the medicament is through worm
Body surface skin is sucked into after digestive system, causes local stimulation, is caused reflectivity polypide excited, is first inhibited polypide sensory nerve
Tip, it is rear to inhibit nervous centralis and cause evil mite dead.The effective object of jervine is similar to nicotine, have tag, stomach poison function,
Can prevent eliminating aphis, aleyrodid, wood louse, planthopper, leaf miner, rice leaf roller, Tetranychus urticae etc., be a kind of fast-acting insecticide.
Macro tetrolide is a kind of mite killing antibiosis as caused by the mutation of streptomyces griseus Liuyang with macrolide structure
Element.Medicine low toxicity, low-residual, can prevent the multiple mites of various crop, control effect is good, to natural enemies security, with conventional pesticide
There is no cross resistance.
Chemical pesticide long-time service be easy to cause environmental pollution, causes food-safety problem, using biological pesticide replacementization
Medicine of learning to farm is research hotspot.The active constituent of different cultivars is compounded, is the very common method for preventing resistance insect pest.It can
It is the important means of integrated control insect pest so as to greatly delay the generation of drug resistance to reduce the usage amount of pesticide.It is existing
There is the compounding for not having jervine and macro tetrolide in technology to report.

Specific embodiment
The specific embodiment of the present invention is described in detail with reference to embodiment, it is to be understood that the guarantor of the present invention
Shield range is not restricted by specific implementation.
Embodiment 1：Jervine and macro tetrolide compound the Toxicity Determination to Tetranychus urticae
Test method：Using slide infusion process, double faced adhesive tape is cut into 2cm × 2cm, is attached to one end of glass slide, gently
The glutinous tetranychid taken on Kidney bean blade back, makes tetranychid back stick on double faced adhesive tape, and each chelicera can be freely movable, is placed in room temperature decentralization
2h is put, it is stringent to reject death, torpescence, worm state and the inappropriate tetranychid individual of position with dissection sem observation, retain active
Deutonymph is test worm sources.Reagent agent with a small amount of acetone is completely dissolved, medicament is diluted into 5-6 matter on the basis of trial test
Concentration is measured, each mass concentration is repeated 4 times, and clear water is control.Mite slide will be carried and immerse liquid, taken out after jog 5s, it is rapid to use
Blotting paper blots the extra liquid in periphery.Slide is placed in the culture dish for being covered with moistening filter paper, is covered with preservative film, be placed in temperature
In 25 DEG C, the incubator of relative humidity 75%, to check death condition under anatomical lens when for 24 hours, mite being touched with writing brush
Body, the motionless person of chelicera are considered as death.The death rate is counted, calculates corrected mortality.
Virulence regression equation, LC50 values is obtained with DPS v12.01 softwares.Then LC50 values are calculated.Finally press the abundant methods of Sun Yun
Calculate co-toxicity coefficient (CTC).
When CTC≤80, then composition shows as antagonism, and as 80 ＜ CTC ＜ 120, then composition shows as being added and make
With when CTC >=120, then composition shows as synergistic effect.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) × 100
Percentage composition+B the medicament toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
The percentage composition of B in agent
Co-toxicity coefficient (CTC)=[mixture actual measurement toxicity index (ATI)/mixture theoretical toxicity index (TTI)] × 100.
1 jervine of table and macro tetrolide are to the Toxicity Determination of Tetranychus urticae
As shown in Table 1, jervine and macro tetrolide compounding are 1:30-20:Tetranychus urticae performance synergy is made in the range of 1
With CTC values are more than 120.When jervine and macro tetrolide compounding are 1:20-5:CTC values are more than 130 in the range of 1, show as showing
Write synergistic effect；Particularly when the proportioning of jervine and macro tetrolide is 1:When 5, CTC values are 140.8, and synergistic effect is most strong.
Embodiment 2：Jervine and macro tetrolide compound the field efficacy to Tetranychus urticae
Test method：For studying object as Kidney bean, any chemical fertilizer and pesticide were not applied other than watering after emergence.Experiment is set
4 repetitions.Per 15 plants of cell label, each strain tetranychid radix is investigated before medicine, starts dispenser after the completion of investigation, spray liquid measure is about
450kg/hm2,10d investigation survival mite amount, calculates Revision insect recluced rate and preventive effect after medicine.
Test medicament：
Medicament 1：24% jervine macro tetrolide wettable powder (jervine 12%, macro tetrolide 12%, sulfomethylated lignin
Sour sodium 3%, NNO5%, pull open powder 1%, 100%) kaolin complements to
Medicament 2：36% jervine macro tetrolide missible oil (jervine 6%, macro tetrolide 30%, N-Methyl pyrrolidone
10%, agriculture breast 400#5%, epoxychloropropane 3%, phenethyl phenol polyethenoxy ether 4%, 100%) dimethylbenzene complements to
2 jervine of table and macro tetrolide compound the field efficacy to Tetranychus urticae
As shown in Table 2, compared with exclusive use, jervine and macro tetrolide compounding can significantly improve it to Tetranychus urticae
Control effect, have significant synergies.The generation of resistance can be slowed down, it is good to crop safety, meet pesticidal preparations
Security requirement.
Further narration is done to the present invention, but present invention is not limited to the embodiments described above above in conjunction with embodiment,
In the knowledge that one skilled in the relevant art has, it can also be made under the premise of present inventive concept is not departed from
Various change.
