In addition, this table refers to the agrochemical compounds containing the compounds of formula (1).2. To control, prevent or control the infection of plants, collected grain crops, seeds or inert materials by plant pathogens, especially fungi, to prepare and use these ingredients in agriculture or horticulture； 1. Claim 1: a formula compound (1),where R¹ and R² are each independently selected from hydrogen, cyano, C₁₋₆ alkyl,cycloalkyl C₃₋₇,a. Alquenilo c832283316a and acquinio c832283316a；1. One to three independently selected substitutes from halogen, Alcoy c832112 and acquilto c83832126 can be selected to replace asphalt, cyclopropyl oxidation, alquenilo and tar；or R¹ and R² together with the carbon atom to which they are attached represent a C₃₋₁₀ cycloalkyl group (which may optionally be substituted with from 1 to 3 substituents independently selected from the group consisting of halogen, C₁₋₆ alkyl,C₁₋₆ alkoxy and C₁₋₆ alkylthio)；R³ and R⁴ are each independently selected from hydrogen, halogen, hydroxyl, C₁₋₆ alkyl,C₁₋₆ alkoxy,cycloalkyl C₃₋₇,a. Alquenilo c832283316a and acquinio c832283316a；in which the alkyl, alkoxy, cycloalkyl, alkenyl and alkynyl groups can be optionally substituted with 1 to 3 substituents independently selected: from halogen, C₁₋₆ alkoxy and C₁₋₆ alkylthio；O R3 and r83088, together with the carbon atoms attached to them, represent C = O, C = nor74919；C = C (Rᵇ) (Rᶜ) or C₃₋₁₀ cycloalkyl (which may optionally be substituted with from 1 to 3 substituents independently selected from the group consisting of halogen, C₁₋₆-alkyl,C₁₋₆ alkoxy and C₁₋₆ alkylthio)；or R² and R³ together with the carbon atoms to which they are attached represent C₅₋₁₀ cycloalkyl (which may optionally be substituted with from 1 to 3 substituents independently selected from the group consisting of halogen, C₁₋₆-alkyl,C₁₋₆ alkoxy and C₁₋₆ alkylthio and, additionally, an annular carbon unit can be replaced by an oxygen or sulfur atom)；each R⁵ independently represents h
