Description

A kind of Pesticidal combination of pyriproxyfen-containing
The application is divisional application, and original application is the patent application " Pesticidal combination of a kind of pyriproxyfen-containing " of Shaanxi Welch Crop Protection Co., Ltd., and the application number of original application is 201210151564.6, and original application day is 2012.05.16.
Technical field
The invention belongs to technical field of pesticide, relate to the application on crop pests of the Pesticidal combination of a kind of pyriproxyfen-containing.
Background technology
Nylar (pyriproxyfen) chemical name: 4-Phenoxyphenyl (RS)-2-(2-pyridine radicals oxygen) propyl ether.Nylar is the chitin synthesis inhibitor of a kind of juvenile hormone type, has strong ovicidal action.Nylar also has interior absorption transfer activity, it is possible to impact is hidden in blade larva behind.The inhibitory action of insecticide is shown that affecting insecticide changes in quality and breeding.The toxicological test of Prodenia litura is showed, and Nylar retains hemolymph middle and high concentration, accelerates the secretion of insecticide prothoracotropic hormone；On the other hand, owing to Nylar can make insecticide lack required stimulating factor of laying eggs, it is suppressed that the hatching of fetal development and ovum, or the ovum not having viability is generated, thus effectively controlling and reach the purpose of Pest control.
Oxygen tebufenozide, furan tebufenozide, tebufenozide, chlorine tebufenozide belong to bishydrazide insect growth regulator, IGR.Bishydrazide insect growth regulator, IGR is that the class developed successively in recent years is efficient, selectivity is strong, environment amenable insect growth regulator, IGR, its action target is the same with insect moulting hormones (20E), it is incorporated into the heterodimer of the superfluous valve albumen (USP) of ecdysone receptor (EcR), transcribing of induction insecticide early gene, but due to bishydrazide compounds sustainable existence in insect bodies, make 20E be absent from situation event can not carry out, as DOPA decarboxylase (DDC) isogenic expression is obstructed, do not synthesize chitin, eclosion hormo can not discharge, finally make larva precocity decortication and dead.
But, in the real process of agricultural production, pest control is easiest to generate the problem that the generation of pest resistance to insecticide.Different cultivars composition carries out composite, is prevent and treat the method that resistant insect is very common.Heterogeneity carries out composite, according to practical application effect, judge certain composite be potentiation, add and or antagonism.In most cases, the composite effect of pesticide is all additive effect, really have potentiation composite seldom, especially potentiation clearly, significantly high composite just less of co-toxicity coefficient.Study through inventor, find to produce after composite to Nylar and methoxyfenozide, furan tebufenozide, tebufenozide, chlorine tebufenozide good potentiation, and not yet open about the relevant report that Nylar and methoxyfenozide, furan tebufenozide, tebufenozide, chlorine tebufenozide are composite.

The embodiment of the present invention is the method adopting Toxicity Determination and field test to combine.First pass through Toxicity Determination, co-toxicity coefficient (CTC) after clear and definite two kinds of medicaments are composite by a certain percentage, CTC < 80 is antagonism, 80≤CTC≤120 are summation action, CTC > 120 is potentiation, on this basis, then carry 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.Adopt the method that first leaching leaf is followed by worm, take out after blade of the same size not in contact with any medicament is soaked 5s in the medicinal liquid configured, naturally dry, put in insect box, then connect for examination larva, raise under 25 DEG C of conditions, often process 3 times and repeat, often repeating examination borer population used is 50, sets blank simultaneously, checks dead borer population in 72h, calculate mortality rate and corrected mortality, try to achieve virulence regression equation and calculate LC50Value.If comparison mortality rate is more than 10%, then it is considered as invalid test.Computing formula is as follows:
Insect corrected mortality is converted into probit value (y), and concentration for the treatment of (μ g/ml) converts logarithm value (x) to, draws virulence regression equation with method of least square, and thus calculates the value of every kind of medicament.Co-toxicity coefficient CTC is calculated according to the abundant equation of Sun Yun.Computing formula following (with Nylar for standard agent, its toxicity index is 100):
TI × the P of theoretical toxicity index (the TTI)=Nylar of MNylarTI × the P of+effective active composition BEffective active composition B
In formula: M is the mixture of different ratio
