Description

The present invention relates to a novel insecticidal and fungicidal composition exhibiting an excellent insecticidal and fungicidal action.

(B) Conventional technology Various chemicals such as organophosphorus, carbamate and pyrethroids have been developed as insecticides and used as single agents and mixed agents. However, conventional insecticides lack the balance of insecticidal spectrum, insecticidal activity at each stage of development of the insect pest, fast-acting, residual-effect, systemic migration, etc. Alternatively, due to problems such as safety against useful insects and natural enemies, and phytotoxicity to crops, the use scene, the number of times of use and the like are limited, so that it cannot be said that satisfactory insecticidal effects are necessarily obtained. In particular, recently, pests with reduced susceptibility to various conventional chemicals, for example, black leafhoppers and planthoppers that are resistant to organophosphates and carbamates in rice fields in Japan have emerged, and a technique for controlling these pests has been established. Is strongly requested.

A similar situation has been observed in the field of fungicides. In particular, recently, blast pathogens of rice or rice sheath blight pathogens have become less sensitive to conventional fungicides, making it difficult to control them. Establishment is strongly demanded.

Further, in recent years, so-called cost reduction has also been strongly demanded for the control of these pathogens, and it is necessary to achieve a high control effect with a small number of treatments and a small amount of a dropped drug. I have.

In recent years, as one of Japan's paddy rice cultivation techniques, mechanical transplantation of seedlings has become widespread, and as a result, not only conventional drug treatment in paddy main fields but also nursery box treatment before transplantation of drugs or There is a strong demand for the development of an excellent drug capable of controlling pests by applying a lateral streak at the time of transplantation, that is, a drug exhibiting excellent medicinal properties and having no harm.

It is already known that the following fungicides have an activity of controlling rice blast or rice sheath blight. For example,

Year, issued by The British Crop Protection Concil).

(C) Problems to be Solved by the Invention However, the actions of the insecticidal compound and the fungicidal compound as described above each independently show only an insecticidal effect or a fungicidal effect. Cannot be controlled at the same time.
On the other hand, the present inventors have found a guanidine derivative or a salt thereof that is effective as an insecticide (Japanese Patent Application No. 63-332192).
