Background technology
The mechanism of action that SDHI classes (succinate dehydrogenase inhibitors) bactericide is is mainly suppression
Pathogen SDA processed, so as to disturb its respiration, its effect is special, strong drug action, persistent, volume increase effect
Fruit is significantly.This series bactericidal agent developed that succeeded at present mainly has furametpyr (furametpyr), biphenyl pyrrole bacterium amine
(bixafen), fluopyram (fluopyram), isopyrazam (isopyrazam), ring benzene pyrrole bacterium amine (sedaxane).
For Reasonable Protection medicament, delay the germ prevention effect for producing and improving medicament drug-fast to new medicament, having must
Carry out rational composition research.The present invention is found through experiments that chitosan oligosaccharide with above-mentioned succinate dehydrogenase inhibitors (SDHI)
Bactericidal composite has unexpected technique effect.
The content of the invention
It is an object of the invention to provide preferable with the effect of succinate dehydrogenase inhibitors (SDHI) containing chitosan oligosaccharide
Bactericidal composition.Two kinds of different structures are compounded, are the effective way for expanding preventing and treating spectrum and improving drug effect, it is often more important that
Avoid or delay generation of the disease to new composition resistance.The purpose of the present invention is realized by following measures.
The invention provides the bactericidal composition containing chitosan oligosaccharide Yu succinate dehydrogenase inhibitors, it is characterised in that the group
Succinate dehydrogenase inhibitors component in compound is furametpyr, biphenyl pyrrole bacterium amine, fluopyram, isopyrazam, ring
One kind in benzene pyrrole bacterium amine, chitosan oligosaccharide is 1 with the quality parts ratio of succinate dehydrogenase inhibitors:10-5:1, it is preferred that shell is few
Sugar is 1 with the quality parts ratio of succinate dehydrogenase inhibitors:4-4:1.
In above-mentioned composition of the present invention, the quality sum of component A and B component accounts for the 1-80% of composition gross mass.
Above-mentioned composition of the present invention can be made into aqua, suspending agent, wettable powder, water dispersible granules, microemulsion or water
Emulsion.
Present invention also offers the method that above-mentioned composition is used to prevent and treat crop disease, it is characterised in that composition is passed through
Spraying, pouring root or seed dressing are applied to ground or the under ground portion of crop.
It is used to prevent and treat the purposes of the various agricultural disease of plant present invention also offers above-mentioned composition, it is characterised in that institute
Disease is stated for the fungus-caused head blight of Ascomycotina, powdery mildew, leaf spot etc., the fungus-caused bakanae disease of Fungi Imperfecti,
Scab etc., rust, smut that Basidiomycotina causes etc., wheat rosette stunt, Maize Dwarf disease, paddy rice that virosis causes
Black streak dwarf etc..Preferably, the disease is the fungus-caused head blight of Ascomycotina, powdery mildew, leaf spot etc., is partly known
The fungus-caused bakanae disease of mushroom, scab etc., rust, smut that Basidiomycotina causes etc., it is further preferred that described
Disease is wheat scab, bakanae disease of rice.
Present invention has the advantages that：
1st, synergistic effect is obvious：Composition shows good synergistic effect in certain ratio range, improves composition
Protection effect.
2nd, use cost is reduced：Preventive effect, preventing and treating spectrum increase are improved because compounding has, access times are reduced, reducing makes
Use cost；
3rd, the resistance to the action of a drug is delayed：Two kinds of composition compoundings of different mechanism of action, pathogen is not likely to produce the resistance to the action of a drug, delays cause of disease
Thing is to the drug-fast generation of single dose.
Specific embodiment
Following examples are further illustrated to of the invention, but the present invention is not limited solely to the combination in present embodiment
Thing and purposes.
Prevention effect of the composition of embodiment 1 to wheat scab
Wheat scab field test is carried out with composition, and has set corresponding single dose and blank, each medicament has been processed
Into aqua, cell 10m is set per medicament2.Using knapsack sprayer routine conventional spray, experiment is sprayed 1 time at the flowering initial stage, the
7~10d carries out second spraying after 1 dispenser, before the 1st medicine, the milk stage of wheat carry out disease survey, often treatment is by right
The sampling of 5 points of linea angulata, accounts for the percentage of whole fringe area to be classified with withered fringe area by 80 plants every, record sick spike numbers at different levels and
Total spike number.
Stage division：
0 grade：Full fringe is disease-free
1 grade：Withered fringe area accounts for less than the 1/4 of full fringe area；
3 grades：Withered fringe area accounts for the 1/4~1/2 of full fringe area；
5 grades：Withered fringe area accounts for the 1/2~3/4 of full fringe area；
7 grades：Withered fringe area accounts for more than the 3/4 of full fringe area；
In theoretical effect, x is the effect of substance A when concentration is a, and y is the effect of substance B when concentration is b, compares reason
By effect and actual effect, the synergy of composition is evaluated, as synergistic effect when being more than theoretical preventive effect with actual preventive effect.Combination
Thing is shown in Table 1 to the preventive effect of wheat scab.
Prevention effect of the composition of table 1 to wheat scab
Wheat scab is tested by chitosan oligosaccharide composition is found, be 1 in composition proportioning:4 and 4:When 1, chitosan oligosaccharide
The composition of composition, chitosan oligosaccharide and biphenyl pyrrole bacterium amine with furametpyr, the composition of chitosan oligosaccharide and fluopyram, shell are few
Sugar is above phase with the composition and chitosan oligosaccharide of isopyrazam and the composition of ring benzene pyrrole bacterium amine to the effect of wheat scab
Answer the theoretical preventive effect of composition.It is contemplated that, chitosan oligosaccharide is 1 in proportioning with the composition of above-mentioned Fungicidal compounds:4-4:When 1 pair
Wheat scab is synergy.
Effect of the composition of embodiment 2 to bakanae disease of rice
According to scheme, built agent and unit dose preparation are prepared in processing, and each medicament is configured to suspending agent, and carries out agent activity
Preliminary experiment.According to activity test determination trial, the concentration that preparation is configured to need.Rice field of once falling ill is selected, with medicament to paddy rice
Seed is dressed seed (concentration is with every kilogram of effective milligram gauge of seed medicament), sowing, seedling.When blank bakanae disease of rice
Instituted an inquiry during generation, 5 points of samplings of diagonal are pressed in often treatment, 80 plants every, determine diseased plant rate.Using Abbot formula, by hundred
Point rate is converted into preventive effect.
In theoretical effect, x is the effect of substance A when concentration is a, and y is the effect of substance B when concentration is b, compares reason
By effect and actual effect, the synergy of composition is evaluated, as synergistic effect when being more than theoretical preventive effect with actual preventive effect.Combination
Thing is shown in Table 2 to the preventive effect of bakanae disease of rice.
The composition of table 2 is to bakanae disease of rice field efficacy
