Description
Technical field
The present invention relates to disinfectant use in agriculture fields, and in particular to a kind of microbicide compositions of containing fluopyram.
Background technology
Powdery mildew is that universal, harm occurs on many important crops seriously, it is more difficult to a kind of worldwide disease of prevention,
It can fall ill from seedling to heading, Ascomycotina powdery mildew purpose fungi is responsible for powdery mildew, and there are many cause of disease species.It should
Class germ can sprout in temperature to 10-30 DEG C of conidium, of less demanding to humidity, can be completed one within 10 days under normal circumstances
Secondary Infection cycie, therefore cause one season of growth repeated multiple times receives of energy of crop and infect, once eruption and prevalence quickly occurs
The characteristics of, bring massive losses to agricultural production.
Fluopyram is pyridine ethyl benzamides fungicide, acts on the respiratory chain of fungal mitochondria, inhibits amber
The activity of acidohydrogenase inhibits fungus spore germination, germ tube elongation, mycelium growth and sporulation to block electron transmission.
Ethirimol has mycelium, conidium, receptive hypha etc. extremely strong killing effect, and can strongly inhibit spore
It is formed, blocks spore to infect source again, bactericidal effect is comprehensively thorough.For the crop to have fallen ill, ethirimol can play very
Good therapeutic effect, no interactions resistance have no adverse effects to plant growth.Bupirimate is for preventing apple, greenhouse rose
The powdery mildew of the plants such as rare, strawberry, effect is good, safe.
There is presently no by fluopyram and ethirimol or bupirimate composite usage in prevention plant powdery mildew
Report.
Invention content
The present invention provides a kind of microbicide compositions of containing fluopyram, have bactericidal activity high, dosage is small, right
Plant growth has special efficacy without influence, feature economic, efficiently, environmentally friendly to prevention crop powdery mildew.
Two classes are had the fungicide of different role mechanism, i.e. fluopyram and ethirimol or ethirimol sulfonic acid by the present invention
Ester is combined, and is processed into the upper easy-to-use preparation of production, compares in two kinds of ingredient exclusive uses, has bioactivity
Height, total dosage declines on unit area, greatly reduces dispenser cost, while delaying the anti-medicine of pathogen to a greater extent
Property generate and development, reduce disease fungus to single bactericide generate resistance risk, extend each group in bactericidal composition
The service life divided, to realize goal of the invention economic, efficiently, environmentally friendly.
The technical scheme is that:
A kind of microbicide compositions of containing fluopyram, which is characterized in that the active component A of the microbicide compositions is fluorine
Pyrrole bacterium amide, B are any one in ethirimol or bupirimate, and the mass ratio of A and B are 1:40 to 40:1.
The microbicide compositions of the containing fluopyram, it is characterised in that:The activearm of the microbicide compositions
It is fluopyram to divide A, and B is any one in ethirimol or bupirimate, and the mass ratio of A and B are 1:5 to 5:1.
The microbicide compositions of the containing fluopyram, it is characterised in that:The dosage form of the microbicide compositions is
Suspending agent, missible oil, water dispersible granules, wettable powder, seed coat agent or microcapsule suspending agent.
The microbicide compositions of the containing fluopyram, it is characterised in that:This microbicide compositions is to rose, strawberry
And various vegetables, field crop powdery mildew have good control effect.
The present invention remarkable result and advantage be:
The present invention has a higher control effect to powdery mildew, and there are notable synergistic effects between two components;It can replace part high price
Position pesticide species, and dosage is reduced, ecological disruption and environmental pollution are effectively reduced, and crop yield and quality can be improved;It can
Delay drug resistance of the germ to single medicament.
Fluopyram, ethirimol and bupirimate single compound are measured first(Hereinafter referred to as medicament)EC50
(Drug safety index), according to the EC of two single medicaments50The portfolio ratio of two medicaments is set by Sun Yunpei's Method, and according to total poison
Coefficient CTC values, determine suitable composition ratio.
Test objective object is wheat powdery mildew, but not limited to this.Experiment uses living body measurement, using spraying tooth in vitro section
Method finds out the EC of each medicament by the linear regression analysis between the probit value and the logarithm of serial drug concentration of preventive effect50,
Co-toxicity coefficient is calculated according to the abundant methods of Sun Yun(CTC), and overall merit is made accordingly.CTC≤80 indicates there is antagonism, 80
< CTC < 120 indicate there is summation action, and CTC >=120 are synergistic effect.CTC value calculating methods are as follows:
The EC of CTC=A50* the EC of B50*100/(The EC50* of M(PA* the EC of B50+PB* the EC of A50))
The indoor biometrics result of 1 fluopyram of table and ethirimol and its compounding to wheat powdery mildew
| Proportioning(A:B) | Slope value(±SE) | Related coefficient | EC50(mg/L) | CTC |
| Fluopyram(A) | 1.138±0.003 | 0.991 | 0.963 | - |
| Ethirimol(B) | 1.420±0.006 | 0.989 | 0.133 | - |

| 1:40 | 1.147±0.004 | 0.990 | 0.112 | 121.30 |
As can be seen from the above data, the fluopyram and ethirimol of different proportion to the fungistatic effect of wheat powdery mildew respectively not
Identical, on the whole, ratio is 40:1 to 1:There is synergistic effect in the range of 40, wherein maximum enhancing proportions are 1:5,
CTC values are 138.67.
The indoor biometrics result of 2 fluopyram of table and bupirimate and its compounding to wheat powdery mildew
| Proportioning(A:B) | Slope value(±SE) | Related coefficient | EC50(mg/L) | CTC |
| Fluopyram(A) | 1.036±0.007 | 0.987 | 0.963 | - |
| Bupirimate(B) | 1.641±0.003 | 0.991 | 0.102 | - |
| 40:1 | 1.241±0.013 | 0.986 | 0.633 | 126.16 |
