Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a fungicide composition for agricultural and horticultural use, and more specifically, a combination of an N-pyridylaniline compound and another specific compound. The present invention relates to an agricultural and horticultural fungicide composition containing an effective parabolite.

(Prior art and problems to be solved by the invention) Many agricultural and horticultural fungicides have been provided to control harmful diseases that occur in crops, but improvements are still desired in various aspects. -ru.

The present inventors have previously discovered that an N-pyridylaniline compound represented by the following general formula exhibits an excellent growth-inhibiting effect on pathogenic bacteria such as Botrytis blight and Scotch blight, which are harmful to agriculture and horticulture. . However, this N-pyridyl-7-diphosphorus compound is not sufficiently effective against specific pathogens such as powdery mildew, and its therapeutic effect is slightly lower than that of preventive effect against each pathogen. It had disadvantages such as being inferior.

(Circumstances leading to the invention) The inventors of the present invention conducted research to solve these drawbacks. :
,Results By using %N-Biridylmany+1-based compounds in combination with other specific compounds, it was shown to have bactericidal activity against pathogenic bacteria as well as to be sufficiently effective against powdery mildew.
In addition, we found that when applied alone, a higher control activity than expected was observed, and furthermore, we found that a synergistic effect could be obtained when used in combination, such as being able to reduce the application amount compared to when applied alone. In addition, it has been found that practicality is improved because a therapeutic effect can be obtained.

(Disclosure of the Invention) That is, the present invention relates to the general formula: (In the formula, %X is a halogen atom or a trifluoromethyl group, Y is a hydrogen atom or a halogen atom, and n is an integer from 1 to 4) Contains as an active ingredient at least one N-bi-11-dyl-2-11 compound represented by the following and at least one other specific compound listed in Table 1 below. A fungicide composition for agricultural and horticultural use,
Due to the above general formula, halogen atoms include fluorine atoms,
