Description

fungicidally active composition

The present invention relates to novel fungicidally active compositions comprising carboxamides of known fungicidal activity in combination with some other fungicides which are also known.

From Japanese Patent Publication No. 61-15 867, No. 62-201 855 and Heping No. 2-11550, it is known that the carboxamides of fungicidal activity used according to the present invention are known, and the activity of these materials is good; but , when administered at low doses, sometimes leaves some problems to be solved.

Furthermore, the following compounds are known to be used against fungi: 5-Chloro-N-(1,3-dihydro-1,1,3-trimethyl-4-isobenzofuranyl)-1,3 -Dimethyl-1H-pyrazole-4-carboxamide, methyl-(E)-methoxyimino-[α-(o-tolyloxy)-o-tolyl]acetate, (E)-2 -Methoxyimino-N-methyl-2-(2-phenoxyphenyl)acetamide, methyl-(E)-2-{2-[6-(2-cyanophenoxy)-pyrimidine -4-yloxy]phenyl}-3-methoxyacrylate, 2',6'-dibromo-2-methyl-4'-trifluoromethoxy-4'-trifluoromethyl-1, 3-thiazole-5-carboxanilide and 3-allyloxy-1,2-benzisothiazole-1,1-dioxide (refer to Japanese Patent Publication No. 45-38 080, Peace 3-246 No. 268 , EP-OS (European Patent Publication) 0,468,684, Japanese Patent Publication No. Hei 4-15228, Sho-63-23852 and Hei 2-131481). However, the activity of these substances is not always satisfactory when used in low doses.

In rice cultivation, rice seedlings are usually mechanically transplanted using a rice transplanter. It is also known to apply fungicides to seedling boxes to control fungal diseases in paddy crops, and applying fungicides in this way saves labor.

From the perspective of biosafety and environmental protection, there is an urgent need to reduce the amount of fungicides applied and the types of active compounds applied. In order to achieve the above-mentioned purpose, a large number of studies are required to reduce the administered dose.

In particular, it is highly desirable to control rice blast, an important disease in rice cultivation, by controlling disease-causing fungi while employing labor-saving operating methods and improving biological safety. Accordingly, it is an object of the present invention to achieve control of rice blast in rice cultivation by using fungicides at effective low doses.

It has now been found that novel compositions comprising the following active compounds have very good fungicidal activity:

A) At least one carboxamide of the formula

in

R ¹ represents an alkyl group of 1 to 4 carbon atoms,

R ² represents a hydrogen atom or a methyl group,

^R represents a hydrogen atom or a methyl group, and

Z represents a halogen atom,

On the condition that the asymmetrically substituted carbon atom, C, is in the (R)-configuration (absolute);

and

B) at least one compound selected from the group consisting of:

5-Chloro-N-(1,3-dihydro-1,1,3-trimethyl-4-isobenzofuryl)-1,3-dimethyl-1H-pyrazole-4-carboxamide , Methyl-(E)-methoxyimino-[α-(o-tolyloxy)-o-tolyl]acetate, (E)-2-methoxyimino-N-methyl-2-( 2-phenoxyphenyl)acetamide, methyl-(E)-2-{2-[6-(2-cyanophenoxy)-pyrimidin-4-yloxy]phenyl}-3-methoxy Acrylates, 2',6'-dibromo-2-methyl-4'-trifluoromethoxy-4'-trifluoromethyl-1,3-thiazole-5-carboxanilide and 3-allyl Oxy-1,2-benzisothiazole-1,1-dioxide.

Surprisingly, the fungicidally active compositions according to the invention have a very pronounced fungicidal effect due to the combined and synergistic action of the mixture of active ingredients. Since the composition is very potent compared to the compound alone even when administered at very low doses, such a synergistic effect cannot be expected on the basis of the technical effect obtained with the active compound alone. Moreover, the fungicidal composition according to the present invention has an excellent and definite effect especially on controlling rice blast.

A general definition of the formamides used in the compositions according to the invention is given in formula (I). In this formula

^R preferably represents methyl, ethyl or isopropyl,

R ² preferably represents a hydrogen atom or a methyl group,

R ³ preferably represents a hydrogen atom or a methyl group,

Z ^- preferably represents a chlorine atom.

N-(R)-[1-(4-Chlorophenyl)-ethyl]-(1S)-2,2-dichloro-1-isopropylcyclopropanecarboxamide.

The synergistic effect is particularly pronounced when the active compounds are present in specific weight ratios in the active compound compositions according to the invention. However, the weight ratios of active compounds in the compositions according to the invention can be varied within relatively wide ranges. Usually, about 0.02 to about 50 parts by weight, preferably about 0.1 to about 10 parts by weight of the compound of group (B) can be used per 1 part by weight of the formamide of the formula (I).
