Description
Technical field
The present invention relates to pesticides application technical fields, and in particular to a kind of Insecticidal combinations of chrysanthemum containing biphenyl rouge and Celastrus angulatus
Object.
Background technique
Tea lesser leafhopper is that tea area, China generally occurs, harmfulness is larger and the primary pest of keypoint control, wherein with vacation
The harm of eye smaller green leaf hopper is the most serious.Currently, tea lesser leafhopper is mainly prevented and treated with Biphenthrin in the market, but due to long-term
Single frequent medication, so that the resistance of tea lesser leafhopper increases, control efficiency is undesirable.
The perennial liana of Celastrus angulatus category Celastraceae Celastrus, is distributed widely in the mound of China the Yellow River, the Yangtze river basin
Mound and mountain area.The root skin and stem skin of Celastrus angulatus contain there are many strength insecticidal constituent, separate mirror from root skin or seed at present
Make dozens of noval chemical compound, especially obtain 4 crystallizations from kind of oil, i.e. Celastrus angulatus ester I- IV, obtained from root skin 5 it is pure
Natural products, i.e. Celastrus angulatus I-V.The important active insecticidal components of these Celastrus angulatus are referred to as Celastrus angulatus (celastrus
angulatus).There is relevant report of the Celastrus angulatus for tea lesser leafhopper at present, as Wen Zhaoming, Wei Jingfeng are delivered
" several plant insecticide prevents and treats tea lesser leafhopper Comparision Test " confirms Celastrus angulatus in the prevention and treatment of tea lesser leafhopper
It is upper that there is good effect.
It is compounded by the pesticide of different role mechanism, is a quick and simple way for delaying pest and disease damage drug resistance
The mechanism of action of diameter, Biphenthrin and Celastrus angulatus is different.At present with the Pesticidal combination of Biphenthrin and Celastrus angulatus mixture
Applied to the prevention and treatment of tea lesser leafhopper, there are no relevant reports.
Summary of the invention
The technical problem to be solved by the present invention is to provide one kind containing Biphenthrin and Celastrus angulatus Pesticidal combination, with solution
The problem of certainly Biphenthrin causes resistance to increase because of single frequent use, and drug effect reduces.
The invention adopts the following technical scheme: a kind of Biphenthrin and Celastrus angulatus Pesticidal combination, effective component is by joining
The weight ratio of benzene pyrethroids and Celastrus angulatus composition, Biphenthrin and Celastrus angulatus is 5-25:1-2, it is preferred that Biphenthrin and hardship
The weight ratio of skin rattan element is 25:2.
The Pesticidal combination, the weight percent of Biphenthrin are 2.5-10%, the weight percent of Celastrus angulatus
For 0.2-1.0%.
The Pesticidal combination press method known in those skilled in the art, corresponding adjuvant is added, be made missible oil,
The agriculturally acceptable dosage form such as aqueous emulsion, suspending agent.
The adjuvant of Pesticidal combination of the invention includes solvent, emulsifier, wetting agent, stabilizer, antifreezing agent, defoaming
Agent, thickener or it is other be beneficial to the known substance that effective component is stable in the formulation and drug effect plays, be all pesticidal preparations neck
Various composition commonly used or allowed to use, is not particularly limited in domain, and specific ingredient and dosage pass through test according to recipe requirements
It determines.
Compared with prior art, the present invention has following technical effect:
(1) there is synergistic function after Biphenthrin and Celastrus angulatus compound by a certain percentage, can be reduced each single dose
Amount of application improves control efficiency.
(2) Biphenthrin is different with the mechanism of action of Celastrus angulatus, the mutually mixed development that can delay pest resistance, favorably
In the service life for extending Biphenthrin.
(3) compared with single use Biphenthrin, the usage amount and access times of Biphenthrin single dose, reductionization be can be reduced
It learns to farm the application of medicine, it is more environmentally protective.
Specific embodiment
Below in conjunction with the indoor joint toxicity measuring test and field medicine effect test for measuring biocidal activity to of the invention
Technical solution and technical effect are described further, and percentage of the present invention is weight percentage.
Inventor has found that Biphenthrin and Celastrus angulatus are mixed right within a certain ratio range by a large amount of screening test
Tea lesser leafhopper has obvious synergistic function, and effect is not only the simple addition of two kinds of medicaments, specifically with following
Bioassay example is illustrated.
One, bioassay example
Embodiment 1: Biphenthrin, Celastrus angulatus and its mixture are to tea tree false eye leafhopper indoor toxicity test
For trying object: tea lesser leafhopper (Empoasca flavescens) picks up from Zhangzhou, Fujian city Nanjing County, on tea tree
Cultivation, the consistent 3 age nymph of picking is for testing.
Test medicine: 97% Biphenthrin raw medicine (Huifeng Agricultural Chemistry Co., Ltd., Jiangsu), 6% Celastrus angulatus mother's medicine
(Xinxiang City, Henan Province east wind chemical plant).
Test method: with reference to (banker auspicious etc., 2009, the regional disparity of Fujian Province's tea lesser leafhopper drug resistance) and pesticide room
Interior bioassay test criterion insecticidal n Y/T 1154.11-2008), using leaching tip method.
The synergistic effect that pharmacy mix is evaluated using the co-toxicity coefficient method (CTC) of Sun Yunpei, when co-toxicity coefficient (CTC) >=
When 120, composition shows as synergistic effect；As CTC≤80, composition shows as antagonism；As 80 < CTC < 120,
Composition shows as summation action.
Test result is shown in Table 1.
1 Biphenthrin of table, Celastrus angulatus and its mixture are to tea lesser leafhopper joint toxicity measuring table
| Reagent agent | Proportion | LC50(mg/L) | Co-toxicity coefficient (CTC) |
| Biphenthrin (A) | / | 2.32 | / |
| Celastrus angulatus (B) | / | 0.71 | / |
| A:B | 5:1 | 1.22 | 137.2 |
| A:B | 10:1 | 1.38 | 138.9 |
| A:B | 15:1 | 1.41 | 143.7 |
| A:B | 20:1 | 1.36 | 154.4 |
| A:B | 25:1 | 1.34 | 159.3 |
| A:B | 5:2 | 1.04 | 134.8 |
| A:B | 15:2 | 1.29 | 141.3 |
| A:B | 25:2 | 1.19 | 166.9 |
| A:B | 1:5 | 1.08 | 73.9 |
The test of 1 co-toxicity of table the result shows that, Biphenthrin and Celastrus angulatus the weight ratio mixture for 5-25:1-2 between
When 120 are all larger than to the co-toxicity coefficient (CTC) of tea lesser leafhopper joint toxicity measuring, have obvious synergistic function.When
When proportion is 25:2, co-toxicity coefficient is maximum, and synergy is the most obvious.

Three, crop field test examples
Embodiment 1: Biphenthrin and Celastrus angulatus compound the field control effectiveness test to tea lesser leafhopper
Experimental design: using conventional spray-on process, when spray, makes every effort to uniformly thoughtful for test.Field tea lesser leafhopper is when application
1-2 is for occurrence in peak period.In every cell by 5 points of diagonal line samplings before application, choosing for every has tea lesser leafhopper ovum and adult
3 plants of tea tree, the insect population of tea lesser leafhopper quantity before statistics is administered.It is small green to investigate residual tea respectively by 3d, 7d, 15d after medicine
Leafhopper work borer population, records borer population living, calculates control efficiency.
Weather is good during test, and daily mean temperature is 18.0-26.8 DEG C.It is raw that each processing cell tealeaves is observed during test
It is long good, find no the generation of phytotoxicity phenomenon.
Test result is shown in Table 2
From table 2 it can be seen that after Biphenthrin is compounded with Celastrus angulatus, prevention and treatment of the mixed agent to tea tree false eye leafhopper
Effect, quick-acting and lasting effect are significantly better than single dose.This significantly delays tea tree smaller green leaf hopper drug resistance to times for spraying is reduced
Generation and reduce control cost be of great significance.
