Abstract
The invention discloses a kind of miticide composition of containing pyriminostrobin, the miticide composition containing active components A and active component B, wherein active components A are selected from following any one compound selected from pyriminostrobin, active component B：Bifenazate, Hexythiazox, Envidor, fenpyroximate or fenisobromolate, and active components A and the weight ratio of active component B are 1 ︰, 80～60 ︰ 1.The present composition has potentiation to the various evil mites for endangering agricultural production, reduces pesticide usage amount, reduces pesticide and stays residual on crop, alleviates environmental pollution, and to person poultry safety, Environmental compatibility is good, and evil mite is not likely to produce Drug resistance.
Description
The application is divisional application, and original application is the entitled of Shanxi Thompson Biological Technology Co., Ltd.'s submission：It is " a kind of
The patent of the miticide composition of containing pyriminostrobin ", Application No.：201210591603.4, the applying date is：2012.12.29
Technical field
The invention belongs to technical field of pesticide, is related to a kind of miticide composition of containing pyriminostrobin answering in crops evil mite
With.
Background technology
Pyriminostrobin (Pyriminostrobin) chemical name：2- tertiary butyl -5- (4- tertiary butyl benzylthios) -4- chlorine pyridazines -
3 (2H) -one, molecular formula：C23H18Cl2F3N3O4.If the medicament to Panonychus citri, red spider into, young demodicid mite be respectively provided with preventing and treating well
Effect, and it is demonstrated by excellent ovicidal activity.
Bifenazate (Bifenazate) molecular formula：C17H20N2O3.It is a kind of new selective foliar spray mite killing
Agent, it is effective to each life stage of demodicid mite.With ovicidal activity and to knocking down rapidly activity into demodicid mite, pole is affected on predatory mite
It is little, it is very suitable for the comprehensive control of insect, plant is not poisoned.
Hexythiazox (Hexythiazox) molecular formula：C17H21C1N2O2S；The new acaricide of Thiazolidine ketone, to plant epidermis
Layer has preferable penetrance, but without Uptake and translocation effect.There is to various plants evil mite strong ovicidal, the spy of children mite is killed
Property, to invalid into demodicid mite, but touch the ovum produced by the female adult worm of medicinal liquid there is the effect for suppressing hatching.The medicine belongs to non-temperature sensitive type and kills
Demodicid mite agent, without significant difference, the longevity of residure is long for the effect used in high temperature or low temperature, is positively retained at 50 days or so.
Envidor (Spirodiclofen) molecular formula：C21H24Cl2O4, chemical name：3- (2,4 dichloro benzene base) -2- oxygen -
1- oxygen spiral shell [4.5] decyl- 3- alkene -4- bases-ST20 ester；With the brand-new mechanism of action, show to suppress lipid
Synthesis.By tagging, each stage of development to demodicid mite is all effective, including ovum.
Fenpyroximate (Fenpyroximate) molecular formula：C24H27N3O4, chemical name：(E) -4 [1,3- dimethyl-(5- benzene
Oxy-1 H- pyrazolyls) methene ammonia oxygen methyl] -1,1 dimethylethyl esters of benzoic acid；Pathogenic bacteria mycelia is prevented to invade neighbouring health thin
Born of the same parents, and generation disease-resistant gene can be induced.Mite class can be directly killed during high dose, mite class decortication can be suppressed during low dosage or laid eggs.
With knocking down and suppressing decorticating, without systemic action.
Fenisobromolate (Bromopropylate) molecular formula：C17H16Br2O3, chemical name：4,4'- dibromo diphenylglycollic acids are different
Propyl ester；A kind of mite killing spectrum is wide, the acaricide that lasting period length, toxicity are low, safer to natural enemy, Apiss and crop.It is contact compared with
By force, without absorbability, to having certain lethal effect into, deutonymph and ovum.Temperature change affects little to drug effect.The medicine is applied to
The crops such as Cotton Gossypii, fruit tree, vegetable and tea, can prevent and treat various evil mites such as tetranychid, wart demodicid mite, line demodicid mite.Evil mite is to the medicine and three chlorbensides

The embodiment of the present invention is the method combined using Toxicity Determination and field test.First pass through indoor virulence survey
It is fixed, clear and definite two kinds of medicaments compound by a certain percentage after co-toxicity coefficient (CTC), CTC ＜ 80 are antagonism, 80≤CTC≤120
For summation action, CTC ＞ 120 are potentiation, on this basis, then carry out field test.
Test method：The mother solution of each mixed agent is diluted to into five series concentrations respectively during test, is respectively placed in beaker
It is standby.Using the method that leaf is followed by demodicid mite is first soaked, by the blade of the same size not in contact with any medicament in the medicinal liquid for having configured
Take out after immersion 5s, dry naturally, be put in foster demodicid mite box, then connect demodicid mite young for examination, raise under the conditions of 25 DEG C, often process 3
Secondary repetition, it is 50 often to repeat examination demodicid mite number used, while setting blank, checks dead demodicid mite number in 72h, calculates mortality rate and correction
Mortality rate, tries to achieve virulence regression equation and calculates LC50Value.If control mortality rate is more than 10%, it is considered as invalid test.Calculate public
Formula is as follows：
Evil mite corrected mortality is converted into into probit value (y), 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 equations of Sun Yun
Number CTC.Computing formula is following, and (with pyriminostrobin as standard agent, its toxicity index is for 100)：
TI × the P of theoretical toxicity index (the TTI)=pyriminostrobin of MPyriminostrobinTI × the P of+effective active composition BEffective active compositionB
In formula：Mixture of the M for different ratio
PEffective active compositionB is effective active composition B ratio shared in the composition
PPyriminostrobinFor pyriminostrobin ratio shared in the composition
B is planted selected from one of Bifenazate, Hexythiazox, Envidor, fenpyroximate or fenisobromolate.
