Abstract
The invention discloses a pesticide composition containing methiadinil and cytosintetidemycin. The pesticide composition comprises active components which are methiadinil and cytosintetidemycin, and common auxiliary components, and a weight ratio of methiadinil to cytosintetidemycin in the composition is 20:1-1:10. A result of a lot of indoor and outdoor tests show that the pesticide composition has a substantial synergist effect on various viruses harmful to the growth of crops, reduces the use amount of pesticides, reduces the residual quantity of the pesticides on the crops, reduces pollution to environment, delays the pesticide resistance of viruses, and prolongs the service life of the pesticides.
Description
Technical field
The present invention relates to composition pesticide and application thereof, specifically with first thiophene lure amine and
Cytosintetidemycin is the binary complex that active component is compounding, is mainly used in virosis on crops
Preventing and treating.
Background technology
First thiophene lures amine to be a kind of thiadiazole plant disease-proof activator, the general entitled N-(5-of chemistry
Methyl-1,3-thiazole-2-base)-4-methyl isophthalic acid, 2,3-thiadiazoles-5-Methanamide.This chemical combination
Virus disease is had by thing well induces disease resisting effect, and mechanism of action produces system for induction plant
System, the anti-disease activity of wide spectrum.
Cytosintetidemycin belongs to cytosine nucleoside novel antiviral agricultural antibiotic, antibacterial, be by
S. ahygroscopicus produces, and virus and pathogenic bacteria are had prevention, therapeutical effect, should as pesticide
With virus incubation period, break virus structure can be extended, reduces virion concentration, improve plant
The ability of opposing virus, thus reach to prevent and treat effect of virosis.May also suppress fungal filament growth,
And plant can be induced to produce resistance protein, improve the immunity of plant.
The most long-time use continuously of pesticide easily produces resistance risk and consumption increases risk,
And then increase cost and carrying capacity of environment, and filtered out by agriculture chemical compounding and there is notable Synergistic
The compositions of effect, can not only reduce Pesticide use amount, reduce use cost, minimizing resistance wind
Danger, moreover it is possible to reduce potential environmental risk.
Present invention applicant is found by experiment that first thiophene lures amine and cytosintetidemycin according to certain weight
Amount ratio combines, and various crop virosis is had significant synergistic function.Through further
Research completes the present invention.
First thiophene lures amine and the mixture of cytosintetidemycin and use, has no report at present.
Summary of the invention
It is desirable to provide a kind of composition pesticide luring amine and cytosintetidemycin containing first thiophene, use
The preventing and treating of virosis on crops.
Technical scheme: a kind of pesticide combination luring amine and cytosintetidemycin containing first thiophene
Thing, lures amine and cytosintetidemycin and conventional auxiliary element including active component first thiophene, and first thiophene lures amine
Being 20:1～1:10 with cytosintetidemycin weight ratio in the composition, first thiophene lures amine and phonetic peptide mould
Element gross weight percentage composition in the composition is 1%～85%；First thiophene lures amine and cytosintetidemycin to exist
Preferred weight ratio in compositions is 10:1～1:1.
In composition pesticide of the present invention, in addition to the active ingredient (s, solvent, cosolvent, breast are also included
Agent, dispersant, wetting agent, thickening agent, antifreezing agent, cyst material, pH adjusting agent,
Defoamer, disintegrating agent, stabilizer, penetrating agent, diffusant, preservative, synergist, poisoning
The pesticide such as palliative, binding agent and filler allow use and acceptable auxiliary element, all
It is conventional in pesticidal preparations or the composition of permission use, is not particularly limited, concrete composition and use
Amount is determined by test according to recipe requirements.
Composition pesticide of the present invention can be prepared as the multiple application being suitable in agricultural production using
Dosage form, reasonable dosage form has microcapsule suspending agent, suspending agent, aqueous emulsion, microemulsion, moisture
Shot agent, wettable powder and ultra low volume liquids.
The production technology of the various application forms of described composition pesticide all belongs to existing known technology,
Do not repeat them here.
Composition pesticide of the present invention is used for preventing and treating crop virosis, should virosis premorbid or send out
The sick initial stage uses.
Compared with prior art, it is an advantage of the current invention that:
1, first thiophene lures that amine and cytosintetidemycin are compounding has significant synergistic function, than list
Agent is used alone and significantly improves the prevention effect of virosis on crops.
2, first thiophene lures amine and two kinds of active component of cytosintetidemycin to compound, and decreases Pesticide use amount,
Reduce use cost, alleviate the pollution to environment.
3, first thiophene lures amine and two kinds of active component of cytosintetidemycin to compound, and the mechanism of action is different,
Action site increases, and has delayed the generation of viral resistance, has added the service life of pesticide.

From table 2 it can be seen that first thiophene lures amine and cytosintetidemycin 20:1～1:10 (by weight)
Proportion in compounding time, co-toxicity coefficient (CTC) is all higher than 120, to rice stripe leaf
Rot all show synergistic function, especially first thiophene lure amine and cytosintetidemycin at 10:1～
When compounding in the range of 1:1 (by weight), synergistic function is the most notable.Visible, first
Thiophene lures that amine and cytosintetidemycin are compounding has reasonability and feasibility.
In sum, a kind of pesticide combination luring amine and cytosintetidemycin containing first thiophene of the present invention
Thing, obvious synergy, compared with existing unitary agent, virus on preventing and treating crops
Sick effect significantly improves, and to Crop securify, is worth popularization and application in agricultural production.
