Description
Technical field
The present invention relates to technical field of pesticide, specifically related to a kind of bactericidal composition of preventing and treating rice blast.
Background technology
Tricyclazole, English name is：Tricyclazole, is mainly used in the preventing and treating of rice blast.Its mechanism of action is mainly
Prevent to adhere to spore intrusion by suppressing B16 cell.Can rapidly by each site absorption of Oryza sativa L., the lasting period is long, efficacy stability and
Anti- rain drop erosion.
Sym-closene, English is general entitled：Trichloroiso cyanuric acid, its bactericidal property is excellent,
It is the wide spectrum of a new generation, the efficient, antibacterial of low toxicity, all there is certain killing action to antibacterial, virus, funguses, in agricultural
In production, can effectively preventing Fusarium and Verticillium wilts, the rice blast of damping-off and Oryza sativa L., banded sclerotial blight, bacterial leaf-blight and thin
The antibacterials such as bacterium property cecospora spot and fungal disease.
For a long time, China widely popularize tricyclazole as rice blast pesticide control, because of its low cost, peasant is ready to connect
Receive, through using so that resistance increases and impact effect for many years.Simultaneously tricyclazole is protective fungicide, to invading cell
Rice blast encephalapthy agent in tissue is almost without killing action.
In agricultural production, mixture is carried out by the pesticide active ingredient of the different mechanisms of action, be the agriculture resistance disease of preventing and treating
Harmful common methods.Screened by formulation of pesticide, the obvious formula of potentiation, be conducive to improving preventing and treating, reduce agricultural cost, favorably
It is the important means of disease comprehensive control in delaying Disease Resistance to develop.At present, with tricyclazole with sym-closene to have
The mixture of effect composition is applied to the report that the research of rice blast there are no correlation.
The content of the invention
It is an object of the present invention to provide a kind of bactericidal composition of preventing and treating rice blast, its formula is to rice blast tool
There is significant potentiation, can effectively control rice blast, be conducive to delaying Disease Resistance, extend tricyclazole in rice blast
Usage cycles in preventing and treating.
The present invention is adopted the technical scheme that：A kind of bactericidal composition of preventing and treating rice blast, effective ingredient is by three rings
Azoles and sym-closene are constituted, and tricyclazole and sym-closene are 1-3 in the weight ratio of compositionss:1-3, it is preferred that three
The weight of ring azoles and sym-closene compares 3:2.
Described bactericidal composition, tricyclazole percentage by weight in the composition is 5-30%, and sym-closene exists
Percentage by weight in compositionss is 5-30%.
The bactericidal composition of the present invention can be according to well known to a person skilled in the art method, adds corresponding adjuvant to prepare
Into agriculturally acceptable wettable powder.
The present invention bactericidal composition add adjuvant include filler, binding agent, dispersant, disintegrating agent, stabilizer or
Other are beneficial to the effective ingredient material that in the formulation stable and drug effect is played.
Compared with prior art, what the present invention was produced has the beneficial effect that：
(1) compared with single dose, the bactericidal composition has obvious potentiation to rice blast, improves prevention effect, and single
Medicament is compared, it is possible to decrease production and use cost.
(2) present invention can reduce field dosage, effectively reduce environmental pollution and pesticide residues.
(3) mechanism of action of effective ingredient is different in bactericidal composition of the invention, is conducive to avoiding and delaying disease
The drug-fast generation of bacterium, is conducive to extending the service life of tricyclazole.

2nd, Application Example
Embodiment 1:The Toxicity Determination of tricyclazole and sym-closene mixture to rice blast
Subjects：Pyricularia oryzae (picks up from field, and separated purification)
Test method：With reference to《People's Republic of China (PRC) agricultural industry criteria NY/T1154.7-2006》, pot-culture method.Choose
The consistent tri-leaf period rice seedlings of growth potential, each is processed from 5 basins for examination rice seedling.By Pyricularia oryzae in Fructus Lycopersici esculenti oat-agar cultures
Cultivate on base, produce after spore with spore under aseptic washing, make the suspension of 1*105 spore/mL, equably spray inoculation is in confession
On examination rice seedling, black plastic bag moisturizing culture 24h in inoculation rear enclosure.After inoculation 24h, chemicals treatment is carried out, each medicament arranges 5
Concentraton gradient, is sprayed with spray tower under 50PSI pressure.After spray, rice seedling is placed in into 25 DEG C or so, relative humidity >=90%
Under the conditions of cultivate, 7d investigates incidence according to the morbidity grade scale of rice blast after medicine, and calculates prevention effect.
Prevention effect is converted into into niqueMin (y), liquor strength (μ g/ml) is converted into logarithm value (x), with method of least square
Concentration EC in calculating virulence regression equation and suppressing50, the toxicity index and co-toxicity coefficient of medicament are calculated according to the abundant methods of Sun Yun
(CTC), i.e., CTC≤80 are antagonism, and 80 ﹤ CTC ﹤ 120 are summation action, and CTC >=120 are potentiation.
Result of the test such as table 1.
The tricyclazole of table 1, the Toxicity Determination of sym-closene and its mixture to rice blast
| Reagent agent | Proportioning | Virulence regression equation (y=a+bx) | EC50(mg/L) | Co-toxicity coefficient (CTC) |
| Tricyclazole (A) | / | Y=4.2277+1.4365x | 3.45 | / |
| Sym-closene (B) | / | Y=4.4523+1.5651x | 2.24 | / |
| A：B | 1:1 | Y=4.6456+1.4078x | 1.79 | 152.0 |

| A：B | 1:10 | Y=4.2785+1.4519x | 3.14 | 73.6 |
Measurement result shows, when the weight ratio of tricyclazole and sym-closene is 1-3:During 1-3, co-toxicity coefficient (CTC)
More than 120, when tricyclazole and sym-closene are 3 in weight ratio:When 2, co-toxicity coefficient is maximum, is 176.6, shows very well
Synergistic function, have good prevention effect to rice blast pathogen.
Embodiment 2:The preparation of the gained of example of formulations 1 is used to prevent and treat the test of pesticide effectiveness of rice blast
In Nanning suburbs, test arranges 5 process to this test arrangement, and the rice blast state of an illness is investigated before medicine, in
The 1st dispenser of state of an illness initial stage, after the 1st medicine 7 days again dispenser once, altogether dispenser 2 times.7 days after last dispenser, investigate respectively within 14 days
Rice blast disease index simultaneously calculates preventive effect.Each corresponding medicament for processing and using dosage are as follows：
Process 1#：25% tricyclazole trichloro-isocyanuric acid wettable powder (15:10), 80 grams of preparation of mu；
Process 2#：30% tricyclazole wettable powder, 120 grams of amount of formulation of mu；
Process 3#：25% trichloro-isocyanuric acid wettable powder, 120 grams of amount of formulation of mu；
Process 4#：Blank (CK)
Result of the test is shown in Table 2.
The preparation of the gained of 2 example of formulations of table 1 is used to prevent and treat the test of pesticide effectiveness of rice blast
| Test process | Preparation usage amount (gram/acre) | 7 days preventive effects (%) after medicine | 14 days preventive effects (%) after medicine |
| Process 1# | 80 | 86.7 | 95.7 |
| Process 2# | 120 | 71.4 | 82.3 |
| Process 3# | 120 | 73.4 | 76.2 |
| Process 4# (CK) | / | / | / |
Result of the test can be seen that：7 days after dispenser, the compositionss of the present invention have preferable preventive effect to rice blast, and drug effect is bright
The aobvious single dose for being better than control；14 days after dispenser, the compositionss of the present invention are 95.7% to rice blast preventive effect, and drug effect is also significantly better than
The single dose of control.Each medicament is showed no poisoning generation in process of the test, to crop safety.
