    A type of fungicidal mixture Technical field
    [0001] This invention involves a fungicidal mixture. It especially involves a fungicidal mixture containing the active elements boscalid and chlorthalonil. Technical context
    [0002] In horticulture and dry crop production, crops are found with a wide variety of fungi and bacterial infections, so they are prone to all kinds of diseases. Often due to the wide variety of pathogenic fungi or
    10 saprophytes on earth (for example, Pythium aphanidermatum, Phytophthora, Rhizoctonia solani, Fusarium and Botrytis cinerea, etc.) and infections of dangerous bacteria (fungal rot, etc.), cause diseases that cause decomposition, rot of the roots and death of the seeds.
    [0003] Boscalid, whose chemical name is 2-chloro-N- (4’-chlorobiphenyl-2-yl) nicotinamide, has the following structural formula:

    20 Boscalid is a germicide of the nicotinamide class, successfully developed for the first time by the German company BASF, with a fairly broad bactericidal spectrum. It has a preventive effect and acts on almost all types of fungal diseases. It is very effective in the prevention of powdery mildew, Botrytis cinerea, root rot, Sclerotinia sclerotiorum and all kinds of diseases caused by rot. Hardly be
    25 produces mutual resistance. It is also effective as a resistance medication against other bacteria. It is mainly used to prevent diseases in rapeseed, grapes, fruit trees, vegetables and fields, among others. The results of the experiments demonstrate that boscalid has a clear prevention and treatment effect on Sclerotinia sclerotiorum of rapeseed, with the use of the drug over time
    30 appropriate, in addition to a preventive effect in infected plants for the first time, as well as in diseases with a control efficiency index greater than 80%.

    Currently, it is much more widespread than other applicable medications.
    [0004] Boscalid is a type of mitochondrial respiration inhibitor such as succinate dehydrogenase inhibitor (SDHI). Through the inhibition of mitochondria, electrons chain the coenzyme Q of succinic acid Q reductase (also called compound II), activating boscalid. The active mechanism towards other types of germicides based on amides and benzamides is similar. It is equally effective in all links in the production chain of a pathogenic bacterium, especially in its inhibitory effect against germination of the outbreak, where its effect is very potent. It also has an extraordinary preventive effect and a very good permeability inside the leaves.
    [0005] The boscalid as a germicide applicable on the surface of the leaves can penetrate vertically into parts of the leaves of the plants and spread upwards. It has an exceptional preventive effect and a safe curative effect. It can inhibit both germination and the prolongation of outbreaks, as well as the coupling of organs. It is effective in all other phases of fungal growth and has excellent duration and resistance to erosion of rainwater.
    [0006] Boscalid is a systemic germicide with a broad spectrum. It can be used to prevent the development of resistance in diseases related to fungicides that inhibit sterols, diamides, benzimidazoles, pyrimidines, anilines, phenylamides and strobilurines. This product can be transported through the xylem up and to the cusp, as well as to the edges of the leaves of the trunk of the plant. It has a vertical penetration effect and is capable of transmitting through the tissues of parts of the leaves to the back of the leaves. However, this product has little effect if vaporized is distributed. Powdered boscalid is mainly used on stalk and leaves to prevent and treat diseases such as powdery mildew, fruit rot (Monilinia spp.), Leaf spots (Mycosphaerella spp.) On grapes, grass, fruit trees, vegetables and garden vegetation , and in diseases caused by Alternaria alternata (Alternaria spp.), Botrytis cinerea (Botrytis spp.) and Sclerotinia sclerotiorum (Sclerotinia spp.). The compound can also be applied in the cultivation of cereals, grapes, peanuts and potatoes, among others.
    [0007] Chlorthalonil (chlorthalonil), whose chemical name is tetrachloro-phosphononitrile (2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile) and with the following structural formula:

    Chlorthalonil is a protective germicide that replaces the benzene class in a wide spectrum of uses. The active mechanisms allow the entry of tri phosphoglyceraldehyde dehydrogenase into the fungus cell. This enzyme combines with cysteine to destroy the enzymatic activity and metabolism of the fungus cell, causing its death. He
    10 chlorthalonil does not act as an indoor transmitter, but after spraying on the body of plants, it adheres well to the surface, making it difficult to wash it from rainwater, so it is effective for longer. It is mainly used in the prevention and treatment of fruit trees, oxidation of vegetables, anthrax, powdery mildew and mold.
    [0008] 15 Invention
    [0009] The objective of this invention is to provide a fungicidal mixture capable of reducing the application rate and improving the activity profile of the known chemical composition of boscalid and chlorthalonil. This invention reduces the total chemical composition used and improves the activity of the mixture in harmful fungi (mixing with effect
    20 synergistic).
    [0010] At the same time we have discovered that, although the use of boscalid and chlorthalonil is joint or individual or in consecutive order, better prevention and treatment of destructive fungi is achieved than when using only one of the compounds.
    [0011] This invention provides a type of fungicidal mixture whose composition of
    25 boscalid and chlorthalonil improve the effectiveness of the mixture in terms of prevention and treatment. In addition, it broadens the spectrum of fungicides and achieves a drug with multiple applications, effective in delaying or preventing the development of pathogenic germs. Surprisingly, the bactericidal activity of the fungicidal mixture of this invention is clearly greater compared to the activity of each of its chemical compounds.
    30 In other words, there is truly an unsuspected synergistic effect, more than just an increase in activity.

    [0012] When comparing the specific weight of the existing chemical compounds with respect to the fungicidal mixture of this invention, the synergistic effect is especially clear. However, the proportions by weight of the chemical compounds of this fungicidal mixture change with respect to the existing ones.
    [0013] The technical proposal that this invention uses to solve these technical problems is the following: a type of fungicidal mixture characterized by containing boscalid and chlorthalonil as active ingredients whose weight percentage is 1: 100-100: 1, optimized 1 : 50-50: 1, more optimized 1: 25-25: 1.

    Seed buds, in powdered or sprinkled mode on plants or soil, or by a joint or separate mixture of boscalid and chlorthalonil.
    [0049] The fungicidal mixture of this invention contains boscalid and chlorthalonil and has a synergistic effect. The bactericidal activity of chlorthalonil and boscalid of the fungicidal compound of this invention is superior and more visible than that of each of these chemical compounds separately. In other words, although it cannot be predicted, there is truly a synergistic effect, rather than just an increase in activity.
    [0050] When we compare the specific weight of the existing chemical compounds with respect to the fungicidal mixture of this invention, the synergistic effect is especially clear.
    [0051] The efficacy of the bactericidal capacity of the fungicidal mixture of this invention is illustrated by the actual examples described below. From other aspects, individually these chemical compounds have a slightly weak bactericidal action; however, the fungicide mixture shows an activity greater than that of each of its elements separately.
    [0052] The technology of this invention compared to the present one has the following advantages:
    This invention provides a fungicidal mixture whose composition is made by combining two elements, boscalid and chlorthalonil, and manages to improve the efficacy of the fungicidal mixture for the purpose of prevention and treatment, and can have a synergistic effect. In addition, it broadens the fungicide spectrum and achieves a drug with multiple applications. On the other hand, because the active mechanisms of boscalid and chlorthalonil are different, it can increase its effectiveness in the protection of diseases, since it hinders the development of resistance to the action of the drug by pathogenic germs. Forms of realization
    [0053] To explain the main aspects of this invention, several embodiments are presented below that are comparatively better.
    [0054] Currently, the combination of effective elements of different pesticides to make a new one is a quick and effective way to develop and manufacture a new pesticide for the prevention and treatment of pathogenic germs.
    P201530900
    06-24-2015
    After mixing different pesticide products, three kinds of results are usually manifested: additive effect, synergistic effect and antagonistic effect. However, the explanation of a specific effect cannot be predicted, since it can only be known through numerous experiments. With an effective formulation, there is a clear increase in the actual results in prevention and treatment and a decrease in the amount of pesticide, since the soil slows the development rate of resistance to the action of the drug by germs . It is a significant means of prevention and comprehensive treatment of germs.
    [0055] The inventor has carried out many tests of the different combinations of boscalid and chlorthalonil to analyze the results by numerous screening tests, and has discovered a combination that achieves a more effective result, which is not just a simple combination of these two substances The embodiments are illustrated below.
