Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains organophosphorus 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 effective to underground root-feeding insect; Also effective to many mite classes, various nematode tools are well killed activity, common insecticide is produced antibiosis insect (as aphid) has good interior the suction to kill activity.
Organophosphorus insecticide is that China uses the insecticides the most extensive, that consumption is maximum, and it is various in style, and performance also varies, but comprehensively gets up to have following characteristics:
(1) insecticidal spectrum broad.
(2) most of kinds have and tag and stomach poison function, have systemic action or osmosis concurrently, main control on the ground, underground, bore dissimilar insects such as moth, pierce-suck type.Its insecticidal mechanism is the activity that suppresses the cholinesterase in the pest body, destroys neural normal conduction, causes a series of nervous system poisoning symptoms, up to death.
(3) toxicity is higher, should take care during use, and guarantee before the agricultural product results there is certain personal distance time, avoids residue of pesticide to poison.
(4) in environment, easily degraded is easily decomposed under alkali condition, therefore, can not use with alkaline matter.
(5) generally safer to crop, be difficult for producing poisoning.
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 after with lythidathion and chlopyrifos, Profenofos, Hostathion, malathion, phoxim compound, and still unexposed about the relevant report of lythidathion and chlopyrifos, Profenofos, Hostathion, malathion, phoxim compound.

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 standby 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 soaked in the soup that configures behind the 5s take out, dry naturally, put into insect box, connect then, under 25 ℃ of conditions, raise for the examination larva, 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 considered as invalid test greater than 10%.Computing formula is as follows:
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 following (with the lythidathion is the standard medicament, and its toxicity index is 100):
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 chlopyrifos, Profenofos, Hostathion, malathion, the phoxim.
