Abstract
The invention discloses the Pesticidal combination of a kind of containing pyriminostrobin, effective active composition is active components A and active component B, wherein active components A is selected from pyriminostrobin, active component B is selected from any one compound following: pyridaben, propargite, avilamycin, tebufenpyrad, and the weight ratio of active components A and active component B is 1 70～70 1.The present composition has potentiation to the various pests of harm agricultural production, decreases pesticide usage amount, reduces pesticide residual quantity on crop, alleviate environmental pollution, and to person poultry safety, Environmental compatibility is good, and insect is not likely to produce Drug resistance.
Description
The application is divisional application, and original application is the " a kind of containing phonetic demodicid mite of Shanxi Thompson Biological Technology Co., Ltd.'s submission
The Pesticidal combination of amine ", Application No.: 201210594212.8, the date of application is: 2012.12.31.
Technical field
The invention belongs to technical field of pesticide, relate to Pesticidal combination the answering on crop pests of a kind of containing pyriminostrobin
With.
Background technology
Pyriminostrobin: being used for preventing and treating panonychus citri, under field test metering, product shows quick-acting and holding effect well
Property.
Pyridaben, propargite, avilamycin, tebufenpyrad belong to common insecticide, are widely used in preventing and treating on crops
Insect pest, prevention effect is preferable.
But, in the real process of agricultural production, pest control is easiest to generate the problem that the product of pest resistance to insecticide
Raw.Different cultivars composition compounds, and is to prevent and treat the method that resistant insect is the most common.Heterogeneity compounds, according to reality
Application effect, judge certain compounding be potentiation, add and or antagonism.In most cases, the compounding effect of pesticide
All additive effect, really have potentiation compounding seldom, especially potentiation clearly, the highest the answering of co-toxicity coefficient
Join the most less.Study through inventor, after finding to compound pyriminostrobin with pyridaben, propargite, avilamycin or tebufenpyrad
Can produce good potentiation, and about pyriminostrobin and pyridaben, propargite, avilamycin or tebufenpyrad compound relevant
Report the openest.
Summary of the invention
The purpose of the present invention is to propose to a kind of there is synergistic function, use cost is low, preventive effect is good containing pyriminostrobin
Pesticidal combination.
The Pesticidal combination of containing pyriminostrobin that the present invention proposes contains active components A and active component B, active components A with
Active component B weight ratio is 1 70～70 1, and described active components A is selected from pyriminostrobin, and active component B is selected from pyridaben, alkynes
One of demodicid mite spy, avilamycin or tebufenpyrad are planted, and active components A and the preferred weight ratio of active component B are 1 50～50 1；More
The weight ratio being preferably pyriminostrobin and pyridaben is 1 25～25 1, and pyriminostrobin is 1 25～20 1 with the weight ratio of propargite,
Pyriminostrobin is 1 10～35 1 with the weight ratio of avilamycin, and pyriminostrobin is 1 25～25 1 with the weight ratio of tebufenpyrad；Optimum
The weight ratio electing pyriminostrobin and pyridaben as is 1 9～9 1, and pyriminostrobin is 1 9～4 1 with the weight ratio of propargite, pyriminostrobin
Being 19 1～5 1 with the weight ratio of avilamycin, pyriminostrobin is 1 5～4 1 with the weight ratio of tebufenpyrad.
The Pesticidal combination of the containing pyriminostrobin that the present invention proposes is for preventing and treating the purposes of insect on crops, described farming
Thing includes cereal crops, legume crop, fibre crops, sugar crop, melon crop, fruits crop, dry fruit crop, hobby
Crop, root crop, oil crop, flower crop, medicinal crop, crop, green manure pasture crop；Described insect bag
Include red spider, Panonychus citri, blister mite, beginning tetranychid, demodicid mite, rust mite, tetranychus viennensis, Tetranychus cinnabarinus, Tetranychus urticae or thorn rust mite.
Active components A, the weight ratio of active component B are 1 70～70 1.The generally weight hundred of active component in compositions
Dividing content is the 0.5%～90% of gross weight, is preferably 5%～80%.According to different preparation types, active component content
Scope is different.Generally, liquid preparation contains the active substance of by weight 1%～70%, preferably 5%～50%；
Solid preparation contains the active substance of by weight 5%～80%, preferably 10%～80%.
At least containing a kind of surfactant in the Pesticidal combination of the present invention, when being beneficial to use, active component is in water
Dispersion.Surface-active contents is the 5%～30% of total formulation weight amount, and surplus is solid or liquid diluent.
The bactericidal composition of the present invention through dilution or directly can be used before use by user.Its preparation can be by generally
Processing method known in those skilled in the art prepare, will after active substance mixes with liquid flux or solid carrier,
Add the one in surfactant such as dispersant, stabilizer, wetting agent, binding agent, defoamer, disintegrating agent, antifreeze etc.
Or it is several.
The Pesticidal combination of the present invention, can be processed into acceptable dosage form on any pesticide, the most on demand
Dosage form be wettable powder, water dispersible granules, suspending agent, aqueous emulsion, microemulsion, microcapsule suspending agent, it is also possible to make outstanding breast

The embodiment of the present invention is the method using Toxicity Determination and field test to combine.First pass through indoor virulence to survey
Fixed, after clear and definite two kinds of medicaments are compounding by a certain percentage co-toxicity coefficient (CTC), CTC ＜ 80 is antagonism, 80≤CTC≤120
For summation action, CTC ＞ 120 is potentiation, on this basis, then carries out field test.
Test method: respectively the mother solution of each mixed agent is diluted to during test five series concentration, is respectively placed in beaker
Standby.Use the method that first leaching leaf is followed by worm, by the blade of the same size not in contact with any medicament in the medicinal liquid configured
Take out after soaking 5s, naturally dry, put in insect box, then connect for examination larva, raise under the conditions of 25 DEG C, often process 3
Secondary repetition, often repeating examination borer population used is 50, sets blank simultaneously, checks dead borer population in 72h, calculates mortality rate and correction
Mortality rate, tries to achieve virulence regression equation and calculates LC50Value.If comparison mortality rate is more than 10%, then it is considered as invalid test.Calculate public affairs
Formula is as follows:
Insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) is converted into logarithm value (x), with minimum
Square law draws virulence regression equation, and thus calculates the value of every kind of medicament, calculates common poison system according to the abundant equation of Sun Yun
Number CTC.Computing formula is following (with pyriminostrobin as standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=pyriminostrobin of MPyriminostrobin+TI × the P of effective active composition BEffective active compositionB
In formula: M is the mixture of different ratio
PEffective active compositionB is the ratio that effective active composition B is shared in the composition
PPyriminostrobinFor the ratio that pyriminostrobin is shared in the composition
B plants selected from one of pyridaben, propargite, avilamycin, tebufenpyrad.
