Preparation of 1'-(p-chlorophenyl)-3',3'-dimethyl-2'-butyl imidazol-1-yl-carboxylate
A 2.14 g quantity of 1-(p-chlorophenyl)-3,3-dimethyl-2-butanol and 0.78 g of pyridine were placed into 30 ml of ethyl acetate and cooled to a temperature of up to 10.degree. C. A 0.6 ml quantity of trichloromethyl chloroformate was added dropwise in small portions to the mixture with stirring. The resulting mixture was stirred at room temperature for 1 hour. with addition of 0.68 g of imidazole and 0.78 g of pyridine, the mixture was subsequently heated to 70.degree. to 80.degree. C. for 2 hours. The reaction mixture was cooled to room temperature, washed with water, dried over anhydrous sodium sulfate and distilled to evaporate off the solvent, giving 2.9 g of the above-identified desired compound.

EXAMPLE 150
Preparation of 1'-(p-chlorophenoxy)-2'-methyl-2'-propyl imidazol-1-yl-carboxylate
A 2.0 g quantity of 1-(p-chlorophenoxy)-2-methyl-2-propanol and 2.0 g of N,N'-carbonyldiimidazole were placed into 30 ml of ethyl acetate, and the mixture was refluxed for 3 hours with stirring. The reaction mixture was then cooled to room temperature, washed with water twice, dried over anhydrous magnesium sulfate and distilled to remove the solvent. The residue was purified by silica gel column chromatography, giving 2.4 g of the above-identified desired compound in the form of a pale yellow oil.

TEST EXAMPLE 3
Curing effect on rice blast
A suspension of spores of Pyricularia oryzae causing the above disease was sprayed onto rice seedlings (in four-leaf stage) planted in 200-ml pots (7.5 cm in diameter). Twenty-four hours thereafter, the emulsifiable concentrate prepared in Formulation Example 2 was sprayed as diluted to a specified concentration onto the rice seedlings. Seven days thereafter, the lesion area percentage was determined, and the control effect was calculated in the same manner as in Test Example 1. The seedlings were also checked for phytotoxicity.

TEST EXAMPLE 4
Control effect on helminthosporium leaf spots on rice
The emulsifiable concentrate prepared in Formulation Example 2 was sprayed, as diluted to a specified concentration, onto rice seedlings (in five-leaf stage) planted in 200-ml pots (7.5 cm in diameter). After the emulsion dried in air, a suspension of spores of Cochliobolus miyabeanus causing the above disease was sprayed onto the seedlings for inoculation. Seven days thereafter, the lesion area percentage was determined, and the control effect was calculated in the same manner as in Test Example 1. The seedlings were also checked for phytotoxicity.
