Description

Detailed Description of the Invention

[0001]

An object of the present invention is to provide an agricultural and horticultural fungicide which is effective against rice blight and pseudo-blight, and has an excellent control effect against rice blast.

[0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an agricultural / horticultural germicidal composition comprising a novel oxetaneazole compound and a certain agricultural / horticultural germicide as active ingredients.

[0003]

The compound represented by the general formula (I) is a known agricultural and horticultural fungicide described in JP-A-3-232883.

[0004]

In recent years, as rice plant cultivation has become densely planted by mechanical transplantation and early cultivation has been established, the occurrence of bacterial wilt disease is increasing in various places, which causes great damage. Further, recently, damages caused by blight-spot disease (pseudo-spot disease) such as brown blight and red sclerotia have also become a problem.

On the other hand, looking at rice blast, which is one of the most important diseases in rice cultivation as well as the blight of rice, many cultivars whose quality has been improved in recent years have very weak resistance to this disease. Therefore, the control of blast disease is becoming more important.

As described above, the above-mentioned various diseases are mixed in many rice growing areas, and simultaneous control of them is essential. In recent years, labor saving has been especially required in rice cultivation, and labor-saving control means has also been required for these diseases.

In view of such a situation, the present inventors have proposed an agricultural and horticultural fungicide which is effective against rice blight and pseudo-blight and has an excellent control effect against rice blast. As a result of continuing intensive studies on the development, by using one kind selected from the compounds represented by the general formula (I) and a certain kind of agricultural and horticultural fungicide, it is possible to use each of them independently. The present invention has been completed by finding that a higher effect, that is, an excellent synergistic effect is exhibited at a low concentration.
