Background
With regard to the activity of pesticides, in particular with regard to crop protection, one of the core problems of the research carried out in this technical field is the improvement of the properties, in particular in terms of biological activity, and the maintenance of this activity over a certain period of time.
The long-term single application of an active compound to prevent and treat diseases can cause the generation of the drug resistance of the diseases, and the prevention effect of the compound is reduced or even completely lost. In addition, the field of plant protection also has requirements with regard to activity spectrum, toxicity, selectivity, application rate, residue composition and favorable formulation feasibility. Therefore, it is a continuing task to develop new fungicides that are superior in some respects to existing fungicides.

The bactericidal composition can treat all plants and plant parts. "plant" means all plants and plant populations such as desirable and undesirable wild plants, cultivars, and plant varieties (whether or not protected by a plant variety or plant cultivar rights-to-human). Cultivated plants and plant varieties may be plants obtained by conventional propagation and cultivation methods, which may be supplemented or supplemented by one or more biotechnological methods, for example using dihaploids, protoplast fusion, random and directed mutations, molecular or genetic markers, or using bioengineering and genetic engineering methods. Plant parts are understood to mean all parts and organs of plants above and below the ground, such as shoots, leaves, flowers and roots, such as leaves, needles, stems, branches, flowers, fruit bodies, fruits and seeds, and also roots, bulbs and rhizomes. Also plants and vegetative and generative propagation material, for example cuttings, bulbs, rhizomes, runners and seeds, belong to the plant part.
The term "plant propagation material" is understood to mean all reproductively competent plant parts, such as seeds, which can be used for the propagation of the latter, and also vegetative materials, such as cuttings or tubers (e.g. potatoes). Thus, plant parts as used herein include plant propagation material. Mention may be made, for example, of seeds, roots, fruits, tubers, bulbs, rhizomes and plant parts.

Preferred plant propagation material of the present invention is a seed. The fungicidal compositions of the present invention are also particularly suitable for the treatment of seeds.
Most of the crop damage caused by harmful fungi is caused by the attack of the seeds during storage or after sowing and during or after germination of the plants. Plants are particularly sensitive to roots and shoots during the growing period and can cause death of the plant even if there is little damage. Another aspect of the present invention provides a method for protecting seeds and germinating plants, which method makes it unnecessary or at least significant additional application of crop protection agents after sowing or after the emergence of the plants. On the other hand, the amount of active compound used is optimized with the fungicidal composition according to the invention in order to provide maximum protection of the seeds and the germinating plants from attack by phytopathogenic fungi, without the plants themselves being harmed by the active compound used.
The present invention therefore also relates in particular to a method for protecting seeds and germinating plants from attack by phytopathogenic fungi by treating the seeds with a fungicidal composition according to the present invention. The invention also relates to the use of the fungicidal compositions according to the invention for the treatment of seeds to protect the seeds and the germinating plants from phytopathogenic fungi.
The control of phytopathogenic fungi which damage the post-emergent plants is effected primarily by treating the soil and the aerial parts of the plants with crop protection agents. In view of the possible effects of crop protection agents on the environment and on the health of humans and animals, it is therefore necessary to minimize the application rates of the active compounds.
The fungicidal compositions according to the invention are suitable for protecting the seed of any plant variety applied in agriculture, in greenhouses, in forestry or in horticulture-or grape cultivars. In particular, it takes the form of seeds of cereals (such as wheat, barley, rye, triticale, millet, oats), soya, sorghum, peas, lentils, maize, cotton, soya, rice, potatoes, sunflowers, beans, coffee, sugar beet, peanuts, rape, olives, cocoa, sugar cane, tobacco, vegetables (such as tomatoes, cucumbers, onions and lettuce), turf grasses and decorative plants. The treatment of cereal and vegetable seeds is of vital importance.
The active ingredients of the fungicidal composition of the present invention, metconazole and imazalil, are applied to seeds either individually or in a suitable formulation. It is preferably treated in a sufficiently stable state that the treatment does not cause any damage to the seed. In general, the treatment of the seeds can be carried out at any point in time between picking and sowing. The seeds commonly used are isolated from the plant and from the cob, husk, stem, cuticle, hair or pulp. Thus, for example, seeds that have been picked, cleaned and dried to a moisture content of less than 15% may be used. Alternatively, seeds may be used which are dried, for example by treatment with water, and then dried again.
Examples of the method of seed treatment include a method of diluting a liquid or solid chemical, a method of directly immersing seeds in a liquid solution without dilution to allow the chemical to permeate the seeds, a method of mixing a solid chemical or liquid chemical with seeds to coat the seeds and thereby adhering the chemical to the surfaces of the seeds, and a method of spraying the chemical to the vicinity of the seeds while planting.
A plant part and plant organ that subsequently grows is any part of a plant produced from plant propagation material, such as seeds. Plant parts, plant organs and plants may also benefit from the pathogenic damage protection obtained by applying the fungicidal composition to plant propagation material. Certain plant parts and plant organs that grow after certain locations may also be considered plant propagation material, which itself may be applied (or treated) with the fungicidal composition; thus plants, other plant parts and other plant organs produced from the treated plant parts and treated plant organs may also benefit from the application of the germicidal composition.
The application of the bactericidal composition to the site needing control to control pathogenic or saprophytic fungi and bacteria in soil or culture medium.
A method for preventing or controlling the infection of cultivated plants by phytopathogenic fungi by applying said fungicidal composition to the soil or to the cultivation medium.
Under general conditions, soil pathogenic bacteria can generate a large amount of bacteria, as long as conditions are favorable for growth and development of the pathogenic bacteria and hosts are susceptible, the pathogenic bacteria can propagate in a large amount and infect the hosts, under the host infected with diseases, the pathogenic bacteria can enter a continuous pathogenic period, propagate and diffuse in a large amount along with continuous cropping of crops, but then nutrients are consumed, or when soil conditions such as temperature, humidity and the like are unfavorable for the pathogenic bacteria, the pathogenic bacteria can enter a dormant period. When the host with disease does not exist, soil-borne disease bacteria can survive in soil, and the soil-borne disease bacteria can survive on the root surface or the fallen leaves of the non-host except the soil-borne disease bacteria with wide host range and have the saprophytic competitive ability. However, different germs are different, and like fusarium can almost survive in soil indefinitely.
The culture medium of the present invention refers to a support capable of rooting and growing crops, such as: examples of the raw material include sand, pumice, vermiculite, diatomaceous earth, agar, gel, polymer, asbestos, wood chips, and bark.
Examples of methods for applying a chemical to soil include a method in which a liquid chemical is diluted in water or applied without dilution directly to the roots of a plant or a seedling bed for raising seedlings, a method in which granules are sown to the roots of a plant or a seedling bed for raising seedlings by spraying a powder, a water dispersible granule or the like to soil and mixing with the whole soil before sowing, and a method in which a powder, a water dispersible granule or the like is diluted and sprayed to a planting hole or a planting furrow before sowing or planting a plant, and sowing is performed.
The treatment method according to the invention can also be used to protect stored products from fungal and microbial attack. According to the invention, the term "stock" is understood to mean natural substances and processed forms thereof of plant or animal origin which have been derived from the natural life cycle and are intended to be preserved for a long period of time. Storage products of plant origin, for example plants or parts thereof, such as stems, leaves, tubers, seeds, fruits or grains, can be protected in the freshly harvested state or in processed form, such as (pre) drying, wetting, comminuting, grinding, pressing or baking. Or wood, in the form of coarse wood such as construction timber, utility poles and fences; or in finished form, such as furniture or articles made of wood. The animal-derived stock is hide, leather, hair, etc. The compositions according to the invention can prevent fungal or bacterial attack such as corrosion, discoloration or mildew on storage. "stock" is preferably understood as meaning natural substances of plant origin and processed forms thereof, more preferably fruits and processed forms thereof, such as pomes, stone fruits, stone-free small fruits and citrus fruits and processed forms thereof.
The present invention provides a method for controlling or preventing infestation of cultivated plants by phytopathogenic fungi, which comprises applying the fungicidal composition of the invention in an agronomically effective and substantially non-phytotoxic application rate to the phytopathogenic fungi and/or to the environment thereof, or to the plants, plant propagation material and to the organs, soil or cultivation media, materials or spaces of the plants to be grown subsequently, in a manner such as seed treatment, foliar application, stem application, drenching, drip, pouring, spraying, misting, dusting, scattering or smoking.
The present invention provides a method of controlling or preventing infestation of cultivated plants by phytopathogenic fungi, either therapeutic, prophylactic or eradication.
A method of controlling or preventing infestation of cultivated plants by phytopathogenic fungi, which method comprises the simultaneous or sequential application of metconazole and imazalil.

Treatment according to the invention may produce superadditive ("synergistic") effects. For example, the application rate and/or the widening of the activity spectrum and/or the increasing of the activity of the fungicidal compositions used according to the invention; it is also possible to obtain the following effects: better plant growth, increased tolerance to high or low temperatures, increased tolerance to drought or to water or soil salt content, improved flowering performance, easier harvesting, accelerated ripening, higher harvest yields, larger fruits, higher plant height, greener leaf color, earlier flowering, higher quality or nutritional value of the harvested product, higher sugar concentration in the fruit, better storage stability and/or processability of the harvested product, which exceeds the actually predicted effects.
The treatment method of the invention may also be used to treat propagation material such as tubers or rhizomes, and may be used to treat seeds, seedlings or transplanted (packing out) seedlings and plants or transplanted plants. This processing method can also be used to process roots. The treatment method of the present invention can also be used for treating the above-ground parts of plants such as the stems, stems or stalks, leaves, flowers and fruits of the plants concerned.
The amount of the germicidal composition of the present invention used depends on various factors, such as the compound used; objects of treatment, such as plants, soil or seeds; the type of treatment, e.g. spraying, dusting or dressing; for treatment purposes, e.g., prophylaxis or therapy; the type of fungus to be controlled or the application time.
Typically for leaf treatment: 5 to 2000g/ha, preferably 10 to 1000g/ha, more preferably 20 to 300 g/ha; for irrigation or drip application, the dosage may even be reduced, particularly when applying inert substrates such as asbestos or perlite;
-for seed treatment: 0.1-2500g/100kg of seeds, preferably 3-1000g/100kg of seeds, more preferably 5-500g/100kg of seeds, even more preferably 5-250g/100kg of seeds, even more preferably 5-100g/100kg of seeds, more preferably 5-50g/100kg of seeds
-applying a treatment to the soil or water surface: 0.1 to 10000g/ha, preferably 1 to 5000 g/ha.
For the preservation of picked fruits and vegetables, 200 times and 2000 times of liquid can be diluted, and the fruits can be drained after being soaked.
The germicidal composition of the invention may be formulated primarily, i.e., the materials in the composition are already mixed, or the components of the composition may be provided in a single dose, mixed in a tank or tank prior to use, and then diluted to the desired concentration. The preparation form provided by the invention is preferably the main form.
The fungicidal compositions of the invention have improved activity against harmful fungi at a reduced total amount of active compound applied (synergistic). The bactericidal composition of the present invention also has an excellent bactericidal effect against bacteria that exhibit resistance to existing bactericides.
The sterilization composition provided by the invention has the advantages that the metconazole and the imazalil are combined, so that the obtained composition has a gain effect on the prevention and treatment effect, the sterilization spectrum is expanded, the multi-purpose effect of one medicine is realized, and the drug resistance of germs is effectively slowed down or avoided. Surprisingly, the fungicidal activity of the fungicidal compositions according to the invention is significantly higher than the sum of the activities of the individual active compounds, there being an unpredictable, truly occurring synergistic effect, not merely a supplementation of the activities.
The bactericidal composition expands the action range of the metconazole and the imazalil in at least two aspects. Firstly, the application rates of metconazole and imazalil are reduced, while the action remains equally good. Secondly, the combination of metconazole and imazalil still achieves a high degree of plant pathogen control even if the individual compounds become completely ineffective at low application rates. On one hand, the spectrum of the plant pathogens which can be prevented and controlled is expanded, and on the other hand, the use safety is improved.
