Description
The application is divisional application, and for the patent application of Shaanxi Welch Crop Protection Co., Ltd., " one kind contains for original application
The Pesticidal combination of Nylar ", the application Wei ︰ 201210151564.6 of original application, original application day 2012.05.16.
Technical field
The invention belongs to technical field of pesticide, are related to a kind of Pesticidal combination of pyriproxyfen-containing answering on crop pests
With.
Background technology
Nylar (pyriproxyfen) chemical name：4- Phenoxyphenyls (RS) -2- (2- pyridyl groups oxygen) propyl ether.Pyrrole
Propyl ether is a kind of chitin synthesis inhibitor of juvenile hormone type, has strong ovicidal action.Nylar also has interior suction
Property transfer activity, can influence to be hidden in the larva of blade behind.On the inhibiting effect of insect show influence insect change in quality and
Breeding.The toxicological test of prodenia litura is showed, Nylar is retained hemolymph middle and high concentration, accelerates insect prothoracic gland tropism
The secretion of hormone；On the other hand, since Nylar can make insect lack the stimulus needed for oviposition, inhibit embryonic development and ovum
Hatching or the no viability of generation ovum, so as to effectively control and achieve the purpose that control of insect.
Oxygen tebufenozide, furan tebufenozide, tebufenozide, chlorine tebufenozide belong to bishydrazide insect growth regulator, IGR.Bishydrazide
Class insect growth regulator, IGR is that the one kind developed successively in recent years is efficient, selectivity is strong, environment amenable insect growth is adjusted
Agent, action target equally, are incorporated into ecdysone receptor (EcR)-surplus valve albumen with insect moulting hormones (20E)
(USP) heterodimer, induces the transcription of insect early gene, but continues in insect bodies due to bishydrazide compounds
In the presence of, prevent the event that 20E occurs in the case of being not present from carrying out, if DOP Adecarboxylase (DDC) it is isogenic expression be obstructed, no
Chitin is synthesized, eclosion hormo cannot discharge, and larva precocity finally be made to peel and dead.
However, in the real process of agricultural production, pest control is easiest to generate the problem that the production of pest resistance to insecticide
It is raw.Different cultivars ingredient is compounded, and is to prevent the very common method of resistant insect.Heterogeneity is compounded, according to reality
Application effect, to judge that certain compounding is synergy, adduction or antagonism.In most cases, the compounding effect of pesticide
All it is additive effect, the compounding for really having synergistic effect is seldom, and especially synergistic effect is clearly, co-toxicity coefficient is very high answers
With just less.It studies, is found Nylar and methoxyfenozide, furan tebufenozide, tebufenozide, chlorine tebufenozide by inventor
Good synergistic effect can be generated after compounding, and about Nylar and methoxyfenozide, furan tebufenozide, tebufenozide, chlorine worm
The relevant report of hydrazides compounding not yet discloses.

The embodiment of the present invention is the method being combined using Toxicity Determination and field trial.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 synergistic effect, on this basis, then carry out field trial.
Test method：The mother liquor of each mixed agent is diluted to five series concentrations respectively during experiment, is respectively placed in beaker
It is spare.Using the first leaching leaf method that is followed by worm, by not in contact with the blade of the same size of any medicament in the liquid being configured
It takes out, naturally dry, is put into insect box after immersion 5s, then connect for examination larva, raised under the conditions of 25 DEG C, often handle 3
Secondary repetition, it is 50, while set blank control often to repeat test worm number used, checks dead borer population in 72h, calculates the death rate and correction
The death rate acquires virulence regression equation and calculates LC50Value.If compareing the death rate is more than 10%, it is considered as invalid experiment.It calculates public
Formula is as follows：
Pest corrected mortality is converted into probit value (y), concentration for the treatment of (μ g/ml) is converted into logarithm (x), with minimum
Square law obtains virulence regression equation, and thus calculates the value of each medicament.Common poison system is calculated according to the abundant equations of Sun Yun
Number CTC.Calculation formula is following (using Nylar as standard agent, toxicity index 100)：
TI × P of theoretical toxicity index (TTI)=Nylar of MNylarTI × P of+effective active composition BEffective active composition B
In formula：M is the mixture of different ratio
PEffective active compositionB is effective active composition B shared ratios in the composition
PNylarFor Nylar shared ratio in the composition
B is selected from one of methoxyfenozide, furan tebufenozide, tebufenozide, chlorine tebufenozide kind.
Application Example two：
For trying pest：Rice-stem borer
Test medicine is provided by Shaanxi Welch Crop Protection Co., Ltd..
