Abstract
The present invention provides a kind of bactericidal composition for rice sheath blight disease controlling, and effective active composition is made of Pyraziflumid and kasugarnycin.Bactericidal composition provided by the invention has significant synergies, and can slow down the generation of germ drug resistance, reduces active constituent usage amount, mitigates environmental pollution.
Description
Technical field
The invention belongs to pesticide fields, and in particular to a kind of bactericidal composition for sheath blight disease controlling.
Background technique
Pyraziflumid is the SDHI class fungicide of Nihon Nihyaku Co., Ltd's exploitation, mainly by inhibiting mitochondria
Succinate dehydrogenase hinders tricarboxylic acid cycle, interferes the division and growth of cell, has protection and therapeutic effect.It is sterilized
Compose it is wider, it is almost all active to all types of fungal diseases, especially to the powdery mildew, black on rice, fruits and vegetables
Star disease, gray mold, sclerotiniose, banded sclerotial blight etc. have good control efficiency.
Kasugarnycin category agricultural antibiotic class low toxicity fungicide, have stronger interior suction permeability, while have prevention and
Therapeutic effect, therapeutic effect are more significant.Its mechanism of action is to interfere the esterase system of the amino acid metabolism of pathogen, is destroyed
The biosynthesis of protein inhibits the growth of mycelia and causes cell granulations, pathogen is made to lose breeding and infection ability, from
And achieve the purpose that kill pathogen controlling disease.
In agriculture actual production process, especially during the prevention and treatment of pathogen of crop, long-term continuous high dose
Application single kind pesticidal preparations, be used only price it is higher, but also be easy to cause pesticide residue, environmental pollution and
The problems such as pathogen drug resistance generates.In order to overcome above-mentioned shortcoming, the present inventor is by screening, it has unexpectedly been found that will
Pyraziflumid and kasugarnycin are used in mixed way, and have unexpected synergistic effect；And in the prior art not
The report that Pyraziflumid and kasugarnycin are used in compounding.
Summary of the invention
The purpose of the present invention is to propose to a kind of with synergistic function, use cost is low, preventive effect is good is used for banded sclerotial blight
The bactericidal composition of prevention and treatment can slow down the generation of germ drug resistance, reduce active constituent usage amount, mitigate environmental pollution.
Technical solution provided by the invention is as follows:
A kind of bactericidal composition for sheath blight disease controlling, in microbicide compositions effective active composition by
Pyraziflumid and kasugarnycin form.
The weight ratio of Pyraziflumid and kasugarnycin is preferably 1:10-20 in bactericidal composition of the present invention:
It 1, is more preferably 1:2-2:1.
Bactericidal composition of the present invention, wherein effective active composition content accounts for the 5-40% of total weight.
Bactericidal composition of the present invention can be applied in combination with agriculturally customary adjuvant, be prepared into agriculturally useful formulations
Such as wettable powder, water dispersible granules, suspending agent, aqueous emulsion, microemulsion.It is preferably prepared to wettable powder.
Bactericidal composition of the present invention containing Pyraziflumid and kasugarnycin is used to prevent and treat the use of crop disease
On the way.It is preferred for preventing and treating the diseases such as rice sheath blight disease.
Compared with prior art, the invention has the following beneficial effects:
Compared with single dose, the bactericidal composition is obvious to banded sclerotial blight synergistic effect, improves control efficiency；Field dosage
It is greatly decreased, reduces pesticide residue and environmental pollution, production and application cost decline, while safety increases.
Specific embodiment
Below with reference to embodiment, specific embodiments of the present invention will be described in detail, it is to be understood that guarantor of the invention
Shield range is not limited by the specific implementation.
Embodiment 1:Pyraziflumid and kasugarnycin compound the toxicity test to banded sclerotial blight
Subjects: sheath blight fungus.
Test method: it is measured using indoor growing performance rate method.The concentration gradient of medicament is determined by preliminary experiment result.With
Medicament is diluted to the mother liquor of corresponding concentration by sterile water.When being cooled to about 45 DEG C after solid medium is sterilized with each medicament mother liquor
Mixing, is made the pastille culture medium plate of respective concentration gradient.Aseptically, the big small bacteria block of 5mm is connected to PDA culture medium
Plate in, the PDA plate for not adding medicament is blank control, and 6 repetitions of every concentration, 25 ± 1 DEG C of constant temperature cultures are to blank pair
When reaching the 2/3 of culture dish according to colony diameter, colony diameter is measured with crossing method, and for statistical analysis to data.With
Least square method calculates concentration EC50 in inhibition, then calculates co-toxicity coefficient (CTC) according to Sun Yunpei's Method.
When CTC≤80, then composition shows as antagonism, and as 80 < CTC < 120, then composition shows as summation action,
When CTC >=120, then composition shows as synergistic effect.
Survey toxicity index (ATI)=(standard agent EC50/ reagent agent EC50) × 100
Percentage composition+B the medicament toxicity index of A in theoretical toxicity index (TTI)=A medicament toxicity index × mixture × mixed
The percentage composition of B in agent
Co-toxicity coefficient (CTC)=[mixture surveys toxicity index (ATI)/mixtures theoretical toxicity index (TTI)] × 100.
1 Pyraziflumid of table and kasugarnycin compound the toxicity test to banded sclerotial blight
As shown in Table 1, Pyraziflumid and kasugarnycin compounding have good control efficiency to rice sheath blight disease,
The weight proportion of Pyraziflumid and kasugarnycin is that phase additive synergism is showed within the scope of 1:20-20:1, is not occurred
Antagonism.The weight proportion of preferred Pyraziflumid and kasugarnycin is 1:10-20:1；Particularly preferred Pyraziflumid and
The weight proportion of kasugarnycin is 1:2-2:1.
2 16%Pyraziflumid kasugarnycin wettable powder of embodiment
Pyraziflumid 8%, kasugarnycin 8%, sodium lignin sulfonate 5%, alkyl phenol polyoxyethylene ether 8%, naphthalene sulphur
Hydrochlorate 6%, kaolin complements to 100%.
3 30%Pyraziflumid kasugarnycin wettable powder of embodiment
Pyraziflumid 20%, kasugarnycin 10%, sodium lignin sulfonate 7%, neopelex 10%,
Alkyl benzene calcium sulfonate 5%, precipitated calcium carbonate complements to 100%.
Embodiment 4Pyraziflumid and kasugarnycin compound the field efficacy to banded sclerotial blight
Test method: referring to GB/T 17980.20-2000 pesticide field efficacy medicine test criterion (one) bactericidal agent for preventing and treating rice
Relevant test method carries out in banded sclerotial blight.
Test medicine: the medicament prepared in embodiment 2 and embodiment 3.
2 Pyraziflumid of table and kasugarnycin compound the field efficacy to banded sclerotial blight
As shown in Table 1, Pyraziflumid and kasugarnycin compound, preventive effect higher to the field efficacy of rice sheath blight disease
Up to 95.4% or more.And composition has significant synergistic function, can slow down the generation of germ drug resistance, less
The usage amount of drug mitigates environmental pollution,
The foregoing is merely presently preferred embodiments of the present invention, all equivalent changes done according to scope of the present invention patent with
