Description

Fungicidal and Insecticidal Compositions

The present invention relates to novel active combinations with fungicidal and insecticidal properties. This composition contains known fungicidally active carboxamides and known pesticidally active compounds.

Fungicidally active carboxamides used according to the invention are described in Japanese Patent Application Laid-Open Nos. 61 (1986) -15 867, Soha 62 (1987) -201 855 and in Pyeongseong 2 (1990) -11 550 have. The activity of these materials is good, but when applied at low doses, there remains a problem to be solved.

Furthermore, (E) -4,5-dihydro-6-methyl-4- (3-pyridylmethyleneamino) -1,2,4-triazine-3 (2H) -one, 5-amino-1- (2,6-dichloro-4-trifluoromethylphenyl) -4- (trifluoromethylsulfinyl) -1H-pyrazole-3-carbonitrile, N- (6-chloro-3-pyridylmethyl)- N-ethyl-N'-methyl-2-nitrovinylidene diamine, 1- (2-chloro-thiazol-5-ylmethyl) -3-methyl-2-nitroguanidine, 1- (2-chloro-thiazole -5-ylmethyl) -3,5-dimethyl-2-nitromino-hexahydro-1,3,5-triazine and bisaroylhydrazide derivatives can be used to control pests such as insects and ticks (Reference: Japanese Patent Application Publication Soha 63 (1988) -315 771, Pyeong 3 (1991) -157 308, Pyeong 5 (1993) -163 266, Pyeong 6 (1994) -192 014 and Pyeong 7 (1995) ) -165 508, and Japanese Patent Publications Hei 2 (1990) -171 and Hei 6 (1994) -776). However, the activity of these materials is not always satisfactory when applied at low doses as above.

In rice cultivation, the transplantation of a young mother using a transplanter is widely performed. In the case of growing rice in this way, it is desired to apply pesticides to the mother bed to simultaneously control pests and fungal diseases and to reduce labor.

In terms of biological safety and environmental conservation, it is strongly desired to substantially reduce the amount of pesticide used and to reduce the number of times the active compound is used. To achieve this, intensive research has been done to minimize the dose of pesticides.

In particular, Lepidoptera (e.g. pyralid moth), Coleoptera (e.g. rice water weevil) and Cicada (e.g. planthopper or leafhopper) while reducing labor and at the same time improving biological safety. It is desirable to simultaneously control harmful crop pests such as leafhoppers and harmful crop pests such as blasts. Accordingly, it is an object of the present invention to control plant diseases and pests in rice cultivation using a combination of pesticides effective at low doses.

Surprisingly, the compositions according to the invention exhibit excellent fungicidal and pesticidal properties due to the synergistic effect of the mixture of active ingredients. This is a phenomenon that cannot be expected with the mechanical effect obtained by using the active compound alone, because the composition is much more effective than the individual compounds even when the composition is used in very small doses.

In particular, the compositions according to the invention are not only bleeding diseases known as the most harmful diseases in rice, but also cicada (eg planthopper and leafhopper), coleoptera (such as rice weevil) and lepidoptera (such as hyacinth and snail) To very harmful pests in the same rice field, even though these pests are resistant to known pesticides such as organophosphates and carbamate pesticides, they are very effective in controlling them simultaneously.
