Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains lythidathion and antibiotics compound.
Background technology
Lythidathion (fosthiazate) chemical name: (RS)-S-sec-butyl-O-ethyl-2-oxo-1,3-thiazoles alkane-3-base sulfo-acid esters of seeing; (RS)-and 3-(sec-butyl sulfenyl (ethyoxyl) phosphonic acids)-1,3-thiazoles alkane-2-ketone, molecular formula: C

2, the main mode of action of lythidathion is to suppress the acetylcholinesterase of target pest, influences the ecology of second larval phase.Be used to prevent and treat ground thrips, Lepidoptera, coleoptera, the many insects of diptera, also very effectively to underground root-feeding insect; Also effective to many mite classes, various nematode tools are well killed activity, common insecticide is produced antibiosis insect (like aphid) has good interior the suction to kill activity.
Ivermectin HCL (Ivermectin) chemical name: 5-O-demethyl-22, the two hydrogen AVM A1 of 23-, molecular formula: C
48H
74O
14, Ivermectin HCL is to be lead compound with the AVM, through two key hydrogenations, and structure optimization and the novel synthetic pesticide succeeded in developing.Structure optimization product as agricultural antibiotic; Compare with the parent AVM; Its expelling parasite and acaricidal activity have not only been kept; And safety is higher, be difficult for to produce resistance, for the production of vegetables, fruit, cotton etc. provide efficient a, high security and with the good biological source insecticide of Environmental compatibility.
AVM (abamectin) molecular formula: C

14(B1b), AVM it be a kind of macrolide disaccharide compounds.Be the natural products that from edaphon, separates, insect and mite class had tag with stomach poison function and faint fumigation action is arranged, no systemic action.It has very strong osmosis to blade, can kill subepidermal insect, and the longevity of residure is long.It does not kill ovum.What its mechanism of action was different with general insecticide is that it disturbs neurophysiology movable; Stimulate and discharge the r-reanal; And the r-reanal has inhibitory action to arthropodan nerve conduction; Become mite, paralysis symptom promptly occurs as if mite, insect, larva and after medicament contacts, inertia is not got food, and is dead after 2-4 days.Because of not causing that insect dewaters rapidly, so its lethal effect is slower.But though predatism and parasite are had direct killing effect, because of plant surface is residual few, therefore little to the damage of beneficial insect.
Emamectin-benzoate (emamectin benzoate) chemical name: 4 '-Biao-methylamino-4 '-the deoxidation abamectin benzoate; Emamectin-benzoate is that a kind of efficient, wide spectrum, the longevity of residure are long; Be good insecticidal/acaricidal agent, its mechanism of action hinders pest movements nerve information transmission and makes the health paralysis dead.The mode of action is main with stomach toxicity, has action of contace poison concurrently, crop is not had interior absorption ability, but crop epidermal tissue is used in the active ingredient infiltration, thereby has the longer longevity of residure.To control cotton boll, Lepidoptera, mite class, coleoptera and homoptera pest have high activity, and do not intersect with other crops generation; In soil, be prone to the degraded noresidue; Free from environmental pollution, in the routine dose scope to useful insect and natural enemy, people, animal safety, can with most of combined use of pesticides.First dimension salt according to the invention is the abbreviation of emamectin-benzoate.
Multiple killing teichomycin (spinosad) mechanism of action is considered to the acting body of nicotinic acid acetylcholinergic receptor, can sustained activation target insect acetylcholine nicotine receptor, but its binding site is different from nicotine and Imidacloprid.Pleocidin also can influence the GABA acceptor, but mechanism of action is unclear.Can make insect benumb rapidly, paralyse, cause death at last.Its desinsection speed can compare favourably with chemical pesticide.Safe, and do not have cross resistance with present common insecticide, be the biological insecticides of low toxicity, efficient, low-residual.Multiple killing teichomycin has insect tags and stomach poison function fast, and blade is had stronger osmosis, can kill subepidermal insect, and the longevity of residure is longer, and some insects are had certain ovicidal action.No systemic action.Can effectively preventing Lepidoptera, diptera and thrips insect, can prevent and treat well also that some measures the pest species of eating blade greatly in coleoptera and the orthoptera, relatively poor to the control efficiency of sucking pest and mite class.Safer to the predator insect, unique because of insecticidal action mechanism, do not find as yet at present to have mutual drug-fast report with other insecticides.Plant safety there is not poisoning.Be suitable for using on vegetables, fruit tree, gardening, the crops.Insecticidal effect receive to rain influence less.
Yet in the real process of agricultural production, the problem that pest control is easy to generate most is the generation of pest resistance to insecticide.The different cultivars composition carries out composite, is the very common method of control resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals all is an additive effect, and the seldom composite of synergistic effect really arranged, especially synergistic effect very obviously, co-toxicity coefficient very high composite just still less.Through inventor's research; Discovery can produce good synergistic effect with lythidathion and Ivermectin HCL, AVM, multiple killing teichomycin, first dimension salt after composite, and it is still unexposed to tie up the composite relevant report of salt about lythidathion and Ivermectin HCL, AVM, multiple killing teichomycin, first.

Lythidathion 12%, first dimension salt 3%, EGME 4%, agricultural newborn 1600#6%, calcium chloride 5%, propane diols 4%, silicone 1.5%, deionized water adds to 100%, through the mixed 15% lythidathion emamectin benzoate water emulsion that gets.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC＜80 are antagonism, and 80≤CTC≤120 are summation action, and CTC＞120 are synergistic effect, on this basis, carry out field trial again.
Test method: respectively the mother liquor of each mixed agent is diluted to five series concentration during test, places beaker subsequent use respectively.Adopt and to soak the method that connects worm behind the leaf earlier, the blade of the same size that does not contact any medicament is soaked taking-up behind the 5s, dries naturally in the soup that configures, put into insect box; Connect then and supply the examination larva, under 25 ℃ of conditions, raise, every processing repeats for 3 times; Every to repeat used examination borer population be 50, establishes blank simultaneously, checks dead borer population in 72h; Calculate lethality and corrected mortality, try to achieve virulence regression equation and calculate LC
50Value.If the contrast lethality then is regarded as invalid test greater than 10%.Computing formula is following:
The insect corrected mortality is converted into probit value (y), and concentration of treatment (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least squares, and calculates the value of every kind of medicament thus.Calculate co-toxicity coefficient CTC according to the abundant equation of Sun Yun.Computing formula is (with the lythidathion is the standard medicament, and its toxicity index is 100) as follows:
TI * the P of theoretical toxicity index (TTI)=lythidathion of M
LythidathionTI * P of+effective active composition B
Effective active composition B
In the formula: M is the mixture of different proportionings
P
Effective active composition BBe effective active composition B shared ratio in composition
P
LythidathionBe lythidathion shared ratio in composition
A is selected from lythidathion;
B is selected from following any one compound: a kind of in Ivermectin HCL, AVM, multiple killing teichomycin, the first dimension salt.
