Description

[Detailed description of the invention]

[Industrial Application Field] The present invention relates to a fungicide composition for agricultural and horticultural use, and more specifically, to a novel fungicide composition that is a mixture of a specific amide-substituted derivative and an active ingredient compound of a known fungicide. This invention relates to a fungicide composition for agricultural and horticultural use. [Prior Art and Problems] The development of agricultural and horticultural fungicides has been widely advanced for the purpose of controlling plant diseases, and many drugs have been put into practical use. However, many of the conventional agricultural and horticultural fungicides have their own drawbacks, and there are very few that are fully satisfactory. For example, the conditions for an excellent agricultural and horticultural fungicide are: ■ It must have a pesticidal effect even when applied in small amounts ■ It must have a pesticidal effect against various diseases ■ It must have a curing effect as well as a preventive effect It is preferable to use a drug that satisfies various conditions such as: ■ No generation of resistant bacteria; ■ Long residual efficacy. In recent years, the control of plant diseases such as fruit trees and sulfur vegetables (e.g., downy mildew, late blight, etc.) has become important, and many agricultural and horticultural fungicides have been put into practical use for controlling these plant diseases. However, each has its drawbacks. For example, fungicides containing acylalanine compounds as active ingredients (such as metalaxyl (common name)), fungicides containing phosphinic acid compounds (such as fosetyl (generic name)), and cyanoxime compounds as active ingredients. Bactericides containing fungicides (such as cymoxanil (generic name)) are in practical use, but these may have a reduced control effect due to the development of resistant bacteria, are only effective against specific diseases, or have residual effects. It has shortcomings such as being short. On the other hand, disinfectants containing dithiocarbamate compounds as active ingredients (e.g., mancozeb (generic name), etc.), disinfectants containing N-haloalkylthio compounds as active ingredients (e.g., cabtan (generic name), etc.), organic chlorine compounds, etc. Disinfectants containing as active ingredients [e.g. chlorothalonil (generic name) etc.], disinfectants containing sulfinic acid compounds as active ingredients [e.g. dichlorofluanid (generic name) etc.], disinfectants containing inorganic copper compounds as active ingredients disinfectants [e.g. basic copper chloride, etc.], bactericides containing organic copper compounds as active ingredients [e.g. oxine copper (common name), etc.], bactericides containing aniline compounds as active ingredients [
For example, fluazinam (generic name), anisidine (generic name)
etc.] and fungicides containing naphthoquinone compounds as active ingredients [e.g., dithianone (generic name), etc.] are in practical use. However, they have the disadvantage that they have almost no curative effect (the effect of suppressing the onset of disease when plants are infected with plant pathogenic bacteria), and their effects are insufficient when applied in small amounts. Therefore, it is necessary to apply it in a relatively large amount, which has the disadvantage that it may cause phytotoxicity to useful plants. [Means for Solving the Problems] The present inventor solved the above problems by using the agricultural and horticultural fungicide of the present invention, which is a mixture of the above-mentioned known fungicide and a specific amide-substituted derivative. He discovered Shiroko and completed the present invention. In other words, the agricultural and horticultural fungicide of the present invention is effective against downy mildew and late blight (these are diseases caused by plant pathogenic bacteria belonging to the same category), which are particularly difficult to control diseases. Compared to the application of single ingredients, it has a control effect (synergistic effect) with a smaller amount of application, and has not only a preventive effect but also a curative effect, and is also effective against bacteria resistant to known fungicides. It has various excellent features including long aftereffects. (Hereinafter, blank space) The present invention is based on the general formula CI) A -C0NIICII-0
