The antibacterial composition is used for preventing and treating diseases caused by ascomycetes, basidiomycetes and imperfect fungi.
Description
Technical field
The invention belongs to the disinfectant use in agriculture field, relate to a kind of preparation and application that contains the bactericidal composition of tridemorph.
Background technology
Sustainable development along with agricultural development; the mankind constantly strengthen environmental protection consciousness; the influence that agricultural chemicals cause environment extremely people is paid close attention to, because a large amount of chemical pesticides that use, and the pollution in various degree that all arrived of air, water source, soil and crops.Therefore, reduce the use of chemical pesticide, release that preventive effect is good, consumption is low, environmental protection, and the Pesticidal products that can delaying drug resistance produces speed become the trend of agricultural chemicals research and development.
Tridemorph (tridemorph) is the morpholine series bactericidal agent.Molecular formula is C
19H
39NO (approximately), chemical name: 2,6-dimethyl-4-tridecyl morpholine.
Tridemorph is a kind of broad spectrum activity systemic fungicide with protection and therapeutic action, can be absorbed by the root of plant, stem, leaf, and the plurality of plant diseases that basidiomycetes, sac fungi and imperfect fungus are caused is effective, mainly is the biosynthesis that suppresses the ergosterol of germ.
But the agent of the long-term tridemorph of use separately list makes disease produce resistance easily, causes problems such as dosage increase, preventive effect reduction, lasting period shortening, is unfavorable for sustainable development.And that the active ingredient of the different mechanisms of action is carried out is composite, makes to delay the common method that disease develops immunity to drugs, and according to the effect in the production application, judge this composite be synergistic effect or antagonism.Complex role is more significantly filled a prescription, and can obviously improve preventive effect, reduces the dosage of agricultural chemicals greatly, also can enlarge fungicidal spectrum, improves germicidal efficiency.
Summary of the invention
The objective of the invention is to propose a kind of generation of disease drug resistance or delaying drug resistance of preventing and produce speed, the bactericidal composition that contains tridemorph that use cost is low, preventive effect is good.
The resistance that may bring at the long-term use of tridemorph list agent takes place, degradation problem under the drug effect.The inventor finds by a large amount of indoor biometricses and field control effectiveness test: tridemorph and methoxy acrylic bactericide use after being mixed with certain proportion, have obvious synergistic effect.
Described methoxy acrylic (strobilurins) bactericide is the new type bactericide that in these years occurs, and the sterilization mechanism uniqueness has and permeates in systemic action, low toxicity, efficient, broad spectrum activity.This series bactericidal agent all is the cell mitochondrial respiration inhibitor of pathogen, shifts by the electronics in the pathogen physiological activity and suppresses mitochondrial respiratory, and the supply of interference cell energy, make the pathogen cell death.Sac fungi, pityrosporion ovale, oomycetes and Fungi Imperfecti all there is good preventive effect.Good to white powder, anthracnose, scab, eqpidemic disease, downy mildew control efficiency.

Embodiment
After different active ingredients are mixed, show three kinds of type of action usually, summation action, synergistic effect and antagonism.But be specially which kind of effect, unpredictable, have only by a large amount of experiments and just can know.The prescription that compound synergic is good owing to obviously improved actual preventive effect, has reduced the agricultural chemicals usage amount, thereby has delayed the drug-fast generation speed of germ greatly, is the important means of scientific prevention and cure disease.
To further instruction of the present invention, the percentage among the embodiment all is weight percentage below in conjunction with embodiment, but the present invention is not limited thereto.
The embodiment of the invention is the method that adopts Toxicity Determination and field trial to combine.Pass through Toxicity Determination earlier, the synergy ratio (SR) after clear and definite two kinds of medicaments are composite by a certain percentage, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect, on this basis, carry out field trial again.
Implementation of an application example one: active component (A) tridemorph is with (B) methoxy acrylic bactericide is composite to the powdery mildew of cucumber Toxicity Determination
Test medicine provides by Shaanxi agricultural chemicals Co., Ltd of U.S. nation.
After the effective inhibition concentration scope of each medicament was determined in prerun, each medicament was established 5 dosage respectively by active constituent content and is handled, and established the clear water contrast.Carry out with reference to " agricultural chemicals indoor bioassay test rule bactericide ", adopt the mycelial growth rate method to measure the virulence of medicament powdery mildew of cucumber.Measure colony diameter with the right-angled intersection method behind the 72h, calculate and respectively handle clean amount of growth, mycelial growth inhibition rate.
Clean amount of growth (mm)=measurement colony diameter-5
Mycelial growth inhibition rate is converted into probit value (y), and liquor strength (μ g/mL) converts logarithm value (x) to, tries to achieve virulence regression equation (y=a+bx) with method of least squares, and calculates the EC of every kind of medicament thus
50Value.Calculate the different proportioning synergy ratios (SR) of two medicaments according to the Wadley method simultaneously, SR＜0.5 is an antagonism, and 0.5≤SR≤1.5 are summation action, and SR＞1.5 are synergistic effect.Computing formula is as follows:
Wherein: a, b are respectively active component (A) tridemorph and (B) methoxy acrylic bactericide shared ratio in combination;
A is selected from tridemorph;
B is a methoxy acrylic bactericide: a kind of in Fluoxastrobin, kresoxim-methyl, pyraclostrobin, oxime bacterium ester, Enestroburin, alkene oxime amine, the ZJ0712.
