Abstract
The invention relates to insecticidal composition containing celastrusangulatus and tolfenpyrad. Active ingredients comprise celastrusangulatus and tolfenpyrad, and the weight ratio of celastrusangulatus to tolfenpyrad is (10-25):(1-2). The formula of the insecticidal composition has a significant synergistic effect and is beneficial to reducing the use quantity of pesticides, reduce residues of chemical pesticides and delay the development of resistance of tea green leafhopper.
Description
Technical field
The present invention relates to agriculture applied technology field, specifically a kind of Insecticidal combinations containing Celastrus angulatus and Tolfenpyrad
Thing.
Background technology
Tea lesser leafhopper Shi Cha area generally occurs, hazardness is larger and the primary pest of keypoint control, wherein little with artificial eye
The harm of greenery Cicadae is the most serious.In order to control the harm of tea lesser leafhopper, often medicament to be adopted is prevented and treated, but due to medicine
Agent frequently uses, and tea lesser leafhopper Drug resistance is aggravated, and prevention effect declines, and drug effect reduces.
The novel pyrazole heterocyclic Insecticiding-miticiding of Tolfenpyrad (tolfenpyrad) Shi Yuan Mitsubishi chemical company exploitation
Agent, its main mechanism is to stop the oxidative phosphorylation of insecticide, also has ovicidal, suppression food oviposition deterrence effect.Mesh
Before, Mo Sai technology company of the U.S. is registered with 30% Tolfenpyrad suspending agent and is applied to prevent and treat tea lesser leafhopper.Because it is single for a long time
Frequently apply, tea lesser leafhopper has produced certain resistance to it.
Celastrus angulatus belongs to the perennial liana of Celastraceae Celastrus, is distributed widely in the mound of China the Yellow River, the Yangtze river basin
Mound and mountain area.The root bark of Celastrus angulatus and peel of stem, all containing multiple strength insecticidal constituents, separate from root bark or seed at present and reflect
Make dozens of noval chemical compound, from kind of oil, particularly obtain 4 crystallizations, that is, Celastrus angulatus ester I- IV, obtain from root bark 5 pure
Natural product, i.e. Celastrus angulatus I-V.The active insecticidal components of these Celastrus angulatus weight are all referred to as Celastrus angulatus
(celastrusangulatus).
Compounded by the pesticide of the different mechanisms of action, be to delay the drug-fast quick and simple way of pest and disease damage
Footpath, compounds for preventing and treating there is no report and applying of tea lesser leafhopper with regard to Tolfenpyrad and Celastrus angulatus at present.
Content of the invention
The technical problem to be solved in the present invention is to provide a kind of Pesticidal combination containing Celastrus angulatus and Tolfenpyrad, its
Formula potentiation is notable, advantageously reduces Pesticide use amount, reduces chemical pesticide residual, is conducive to delaying the resistance of tea lesser leafhopper
Development.
The present invention adopts the technical scheme that：A kind of Pesticidal combination containing Celastrus angulatus and Tolfenpyrad, effective ingredient
It is made up of Tolfenpyrad and Celastrus angulatus, the weight of Tolfenpyrad and Celastrus angulatus is than for 10-25:1-2 is it is preferred that azoles worm acyl
The weight of amine and Celastrus angulatus is than for 25:2.
The Pesticidal combination of the present invention, according to method known in those skilled in the art, adds corresponding adjuvant, makes
The agriculturally acceptable dosage form such as aqueous emulsion, cream, suspending agent.
Adjuvant required for the Pesticidal combination of the present invention include solvent, emulsifying agent, wetting agent, stabilizer, antifreezing agent,
Defoamer, thickening agent or other are beneficial to the known substance that effective ingredient is stablized in the formulation and drug effect plays, and are all pesticide systems
Various composition that is conventional or allowing use in agent field.
Compared with prior art, the present invention possesses following beneficial technique effect：
(1) Tolfenpyrad and Celastrus angulatus have notable synergistic effect after mixture by a certain percentage, can reduce each single dose
Amount of application, improves prevention effect.
(2) Tolfenpyrad is different with the mechanism of action of Celastrus angulatus, mutually uses with and can delay or overcome pest resistance to insecticide
Produce, extend the service life of Tolfenpyrad.
(3) present invention can reduce amount of application on Folium Camelliae sinensis for the Tolfenpyrad single dose and access times, alleviates chemical pesticide
Residual, more environmental protection.
Specific embodiment
Below in conjunction with the indoor joint toxicity measuring test and field medicine effect test measuring biocidal activity to the present invention's
Technical scheme and technique effect are described further, and percentage ratio of the present invention is all weight percentage.
Inventor, by substantial amounts of screening test, finds Tolfenpyrad and Celastrus angulatus mixture pair in certain ratio range
Tea lesser leafhopper has obvious synergistic function, and its effect is not only the simple addition of two kinds of medicaments, concrete with following
Bioassay example is illustrated.
First, bioassay example
Embodiment 1：Tolfenpyrad, Celastrus angulatus and its mixture are to Camellia sinensis false eye leafhopper Toxicity Determination
For trying object：Tea lesser leafhopper (Empoasca flavescens) picks up from Zhangzhou, Fujian city Nanjing County, in Camellia sinensis
Cultivation, 3 consistent age nymphs are used for testing picking.
Test medicine：95% Tolfenpyrad active compound (Mo Sai technology company of the U.S.)；(Henan Province is new for 6% Celastrus angulatus mother's medicine
City of township east wind chemical plant produces)
Test method：With reference to (banker is auspicious etc., and 2009, the drug-fast regional difference of Fujian Province's tea lesser leafhopper) and pesticide room
Interior bioassay test criterion insecticidal n Y/T 1154.11-2008), using leaching tip method.
Co-toxicity coefficient method (CTC) using Sun Yunpei to evaluate the potentiation of pharmacy mix, when co-toxicity coefficient (CTC) >=
When 120, compositionss show as potentiation；When CTC≤80, compositionss show as antagonism；As 80 ＜ CTC ＜ 120,
Compositionss show as summation action.
Result of the test is shown in Table 1.
Table 1 Tolfenpyrad, Celastrus angulatus and its mixture are to tea lesser leafhopper joint toxicity measuring table
| Reagent agent | Proportioning | LC50(mg/L) | Co-toxicity coefficient (CTC) |
| Tolfenpyrad (A) | / | 2.79 | / |
| Celastrus angulatus (B) | / | 0.82 | / |
| A:B | 10:1 | 1.40 | 163.5 |
| A:B | 10:2 | 1.46 | 136.5 |
| A:B | 15:1 | 1.68 | 144.4 |

The preparation method of embodiment 4 is：By Tolfenpyrad and Celastrus angulatus active compound, solvent, emulsifying agent dissolving, then with water
Mixing, and the high speed shear of the high-speed stirred of reacted kettle and cutter, that is, be obtained 8.0% Tolfenpyrad Celastrus angulatus water and milk
Agent.
3rd, land for growing field crops test examples
Embodiment 1：Tolfenpyrad and Celastrus angulatus compound the field control effectiveness test to tea lesser leafhopper
EXPERIMENTAL DESIGN:Test, using conventional nebulization, makes every effort to uniformly thoughtful during spray.During dispenser, field tea lesser leafhopper is
2-3 is for occurrence in peak period.The sampling of 5 points of diagonal is pressed in every cell, every selection has tea lesser leafhopper ovum and adult before dispenser
3 plants of tea tree, the insect population of tea lesser leafhopper quantity before statistics dispenser.After medicine 3d, 7d, 15d respectively investigate residual tea little green
Leafhopper work borer population, records borer population of living, calculates prevention effect.
During test, weather is good, and daily mean temperature is 20.4-27.5 DEG C.Each process cell Folium Camelliae sinensis life is observed during test
Long good, all find no poisoning phenomenon and occur.
Result of the test is shown in Table 2
From table 2 it can be seen that after Tolfenpyrad is compounded with Celastrus angulatus, the preventing and treating to Camellia sinensis false eye leafhopper for the mixed agent
Effect, quick-acting and lasting effect are all significantly better than single dose.This dosage advantageously reducing Tolfenpyrad and times for spraying, favorably
In reducing the pesticide residues on Folium Camelliae sinensis, to significantly delaying the drug-fast generation of Camellia sinensis smaller green leaf hopper and reduction cost accounting, there is weight
Want meaning.
