Technical Field

The present invention relates to a plant disease control agent. More specifically, the present invention relates to a plant disease control agent, a novel compound, and a method for controlling a plant disease. The present application claims priority based on japanese patent application No. 2017-052072, applied in japan on day 17 at 2017 and month 17, and on japanese patent application No. 2017-216236, applied in japan on day 11, month 9, 2017, the contents of which are incorporated herein by reference.

Background

Plants have acquired a physical and chemical resistance mechanism in the course of evolution against attacks by external pathogenic bacteria. The physical resistance mechanism is, for example, a coating such as a wax layer and/or a cuticle layer (a cuticle layer), or a cell wall, and serves as a barrier to invasion of pathogenic bacteria. On the other hand, the chemical resistance mechanism is a system that inhibits the growth of pathogenic bacteria, and examples thereof include resistance factors that are accumulated in nature in plants, and resistance factors that are biosynthesized and accumulated in an inducible manner.

In recent years, in order to protect plants from disease pressure, the following attempts have been made: by administering a drug from the outside, a chemical resistance mechanism is activated, and the tolerance of the plant is improved. Such an agent is called a resistance inducer, and various inducers have been studied. For example, it has been found that resistance to Tobacco Mosaic Virus (TMV) is induced by treating tobacco with salicylic acid or acetylsalicylic acid (see non-patent document 1).

From the viewpoint of growing healthy plants and securing food, it is very useful to induce resistance in plants in this way to protect the plants from infection with phytopathogens or phytopathogenic bacteria.

Chlorine-substituted isonicotinic acid derivatives have been disclosed to have a plant disease control effect (patent documents 1 to 5). However, it is known that the above-mentioned compounds may cause phytotoxicity, and the effect of controlling plant diseases may be weak. Further, similar plant disease control agents are disclosed for fluorine-substituted isonicotinic acid derivatives (patent documents 6 to 10), but there is no specific description about the plant disease control agent of the present invention.

Disclosure of Invention

In 1 embodiment, the present invention provides a method for controlling a plant disease, wherein the plant disease control agent or the compound is brought into contact with a plant or a seed or contained in a cultivation bed. The plant disease control agent or the compound may be used in the form of the plant disease control composition.

When the plant disease control agent or the compound is brought into contact with a plant, the plant disease control agent or the compound may be brought into contact with a stem, leaf, root, rhizome, tuber, bulbous root, germinated bud, or the like of the plant. Further, the plant disease control agent or the compound may be brought into contact with a seed of a plant. The cultivation bed may be soil, field water for growing rice, a carrier for growing plants, water for hydroponic cultivation, or the like. Hydroponic water may also contain nutrients.

In the method of the present embodiment, the method of bringing the plant disease control agent or the compound into contact with a plant or a seed or a method of including the agent in a cultivation bed is not particularly limited as long as it is an application method generally used in agriculture and horticulture, and examples thereof include stem and leaf spreading, water surface application, soil treatment, seedling box application, seed treatment, immersion treatment, fertilizer mixing, irrigation water mixing, and the like.

The application amount of the plant disease control agent of the present embodiment can be determined in accordance with the type and degree of the target disease, the type of the target crop, and the target site, considering application methods such as aerial application and ultra-fine application, in addition to the application method.

For example, when the plant disease control agent is spread on plant stems and leaves, a solution obtained by diluting 1 to 1000g of the agent with 50 to 1000L of water per 10 acre (are) in the form of an emulsion, water-dispersible granules or flowable agent, and about 1 to 10kg of the agent per 10 acres in the form of a powder can be used.

When the plant disease control agent is applied to soil, for example, in the form of granules, about 1 to 10kg per 10 acres can be used.
