The present composition has synergistic effect to the multiple harmful mite of harm agricultural production, has reduced agricultural chemicals dosage, has reduced agricultural chemicals and stay residual on crop, has alleviated environmental pollution, and to person poultry safety, Environmental compatibility is good, and evil mite is difficult for developing immunity to drugs.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of miticide composition containing phonetic mite amine in agricultureApplication on crop evil mite.
Background technology
Phonetic mite amine (Pyriminostrobin) chemical name: 2-tertiary butyl-5-(4-tertiary butyl benzyl sulphurBase)-4-chlorine pyridazine-3(2H)-one, molecular formula: C23H18Cl2F3N3O4. This medicament is to entirelyIf pawl mite, red spider become, young mite all has good prevention effect, and showed excellenceOvicidal activity.
Bifenazate (Bifenazate) molecular formula: C17H20N2O3. It is a kind of new selectiveFoliar spray acaricide, effective to each life stage of mite. Have ovicidal activity with to becomingMite knock down rapidly activity, minimum on predatory mite impact, be very suitable for the Synthetic of insectReason, does not poison plant.
Hexythiazox (Hexythiazox) molecular formula: C17H21C1N2O2S; Thiazolidine ketone is newType acaricide, has good penetrability to plant epidermis layer, but without interior suction conduction. RightIf the characteristic that various plants evil mite has strong ovicidal, kills children mite, to becoming mite invalid, but connectsContact the ovum that the female adult of liquid produces and there is the effect that suppresses hatching. This medicine belongs to non-temperature sensitive type and killsMite agent, the effect using in the time of high temperature or low temperature is without significant difference, and the longevity of residure is long, can keepAbout 50 days.
Spiral shell mite ester (Spirodiclofen) molecular formula: C21H24Cl2O4, chemical name: 3-(2,4-Dichlorophenyl)-2-oxygen-1-oxygen spiral shell [4.5] last of the ten Heavenly stems-3-alkene-4-base-2,2-dimethyl butyrate acid esters; Have brand-newThe mechanism of action, show and suppress the synthetic of lipid. By each stage of development of tagging to miteAll effective, comprise ovum.
Fenpyroximate (Fenpyroximate) molecular formula: C24H27N3O4, chemical name: (E)-4[1,3-Dimethyl-(5-phenoxy group-1H-pyrazolyl) methene ammonia oxygen methyl] benzoic acid-1,1 dimethyl ethyl ester;Stop germ mycelia to invade contiguous healthy cell, and can induce generation disease-resistant gene. High doseTime can directly kill mite class, when low dosage, can suppress mite class decortication or lay eggs. There is knocking down and press downDecorticating processed, without systemic action.
Fenisobromolate (Bromopropylate) molecular formula: C17H16Br2O3, chemical name: 4,4'-Dibromo diphenylglycollic acid isopropyl ester; One kills that mite spectrum is wide, the lasting period is long, toxicity is low, to natural enemy,The acaricide that honeybee and crop are safer. Tagging property is stronger, without interior absorption, if to becoming miteAll there is certain lethal effect with ovum. Variations in temperature is little on drug effect impact. This medicine is applicable to cottonThe crops such as flower, fruit tree, vegetables and tea, can prevent and treat the multiple harmful mites such as tetranychid, goitre mite, line mite.Evil mite has cross resistance to this medicine and dicofol, when use, will note.
But, in the real process of agricultural production, the problem that control evil mite the most easily producesIt is the drug-fast generation of evil mite. Different cultivars composition carries out composite, is to prevent and treat resistance evil mite veryCommon method. Heterogeneity is carried out composite, according to practical application effect, judges certainComposite be synergy, add and or antagonism. In most cases, the composite effect of agricultural chemicalsFruit is all additive effect, really has the composite little of synergistic effect, and especially synergistic effect is non-Chang Mingxian, co-toxicity coefficient very high composite just still less. Through inventor's research, finding willAfter phonetic mite amine and Bifenazate, Hexythiazox, spiral shell mite ester, fenpyroximate or fenisobromolate are composite, can produceWell synergistic effect, and about phonetic mite amine and Bifenazate, Hexythiazox, spiral shell mite ester, azolesThe composite relevant report of mite ester or fenisobromolate is not yet open.

The embodiment of the present invention is the method that adopts Toxicity Determination and field test to combine. FirstBy Toxicity Determination, the co-toxicity coefficient after clear and definite two kinds of medicaments are composite by a certain percentage(CTC), CTC < 80 is antagonism, and 80≤CTC≤120 are summation action, CTC> 120 is synergistic effect, on this basis, then carries out field test.
Test method: when test, respectively the mother liquor of each mixed agent is diluted to five series concentration,Be placed in respectively beaker for subsequent use. Adopt and first soak the method that connects mite after leaf, will not contact any medicamentBlade of the same size in the liquid configuring, soak 5s after take out, naturally dry, putEnter to support in mite box, then connect for the young mite of examination, under 25 DEG C of conditions, raise every processing 3 timesRepeat, every to repeat examination mite number used be 50, establishes blank simultaneously, checks extremely in 72hMite number, calculates the death rate and corrected mortality, tries to achieve virulence regression equation and calculates LC50Value.If the contrast death rate is greater than 10%, be considered as invalid test. Computing formula is as follows:
Evil mite corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts toLogarithm value (x), draws virulence regression equation with least square method, and calculates thus every kind of medicineThe value of agent, calculates co-toxicity coefficient CTC according to the abundant equation of Sun Yun. Computing formula following (withPhonetic mite amine is standard medicament, and its toxicity index is 100):
TI × the P of theoretical toxicity index (TTI)=phonetic mite amine of MPhonetic mite amine+ effective active composition BTI × PEffective active compositionB
In formula: the mixture that M is different proportionings
PEffective active compositionB is effective active composition B shared ratio in composition
PPhonetic mite amineFor phonetic mite amine shared ratio in composition
B is selected from Bifenazate, Hexythiazox, spiral shell mite ester, fenpyroximate or fenisobromolate itA kind of.
