Description of the Prior Art A number of fungicidal compounds have been in practical use to protect crops from various pathogenic fungi; and they may be classified into several groups having similar structural features.

For this reason, continuous efforts have been undertaken to develop fungicides having new structures . Such efforts have led to the development of new fungicides, e.g., propenoic ester derived from strobilurin(U.S. Patent No. 4,994,495; WO 94/19331; and U.S. Patent No. 5,003,101). However, these propenoic ester derivatives have the problem of limited fungicidal activity. Summary of the Invention Accordingly, it is a primary object of the present invention to provide a novel compound having a superior fungicidal activity against a wide spectrum of plant pathogenic fungi.

The plant was kept at room temperature for 24 hours to let the solvent evaporate, and then, a pathogenic fungus was inoculated thereonto . The plant was held in a humidity chamber for 24 hours, transferred to an plant growth room kept at 20 to 27 °C and a relative humidity of 60 to 80% and kept to induce disease. Subsequently, the lesion area(L.A.) attacked by the pathogenic fungus was_ measured according to a method of Cho(Cho, K.Y., Search Report by Korea Research Institute of Chemical Technology (1989) )" . This procedure was repeated twice for each test. 10% Acetone solution containing 250 ppm of Tween-20 was used as a control. The fungicidal activity of the compound of the present invention is repressed by a control value (C.V.) calculated as; .A. of control - L.A. of test C.V. (%) = X 100 L.A. of control Test Example 1 : Fungicidal activity against Rice Blast (RCB) disease Pyricularia oryzae Carvara KA301 was inoculated on a rice bran agar medium (rice bran 20 g, dextrose 10 g, agar 15 g and distilled water 1 2 ) and cultured at 26 °C for 1 week. The surface of the medium was scratched using a rubber polishman to remove aerial mycelia, and cultured under a fluorescent light for 48 hours to form a spore. Spores were suspended in sterilized water at a concentration of lxlO 6 spore/ml. The spore suspension was sprayed enough to soak the leaves of a RBC disease- sensitive Nakdong rice plant having 3 or 4 leaves . The rice plant was held in a humidified dark room for 24 hours, transferred to an incubator kept at 24 to 28 °C and a relative humidity of more than 80% and kept for 5 days to induce RCB. L.A. on a fully grown leaf appearing underneath an uppermost leaf was measured to calculate an C.V. Test Example 2 : Fungicidal activity against Rice Sheath Blight (RSB) disease Rhizoctonia solani AG-1 was cultured on a PDA medium(potato 200 g, dextrose 20 g, agar 20 g and distilled water 1 & ) for 3 days and the agar disc(diameter 0.6 cm) was inoculated and cultured on sterilized wheat bran medium in a 1 & bottle at 26 to 28 °C for 7 days. A mycelial mass was ground using a homogenizer, inoculated uniformly on soil of a pot wherein a Nakdong rice plant having 2 or 3 leaves and an height of 5 cm grew, and kept in humidity polyvinyl chamber for 5 days to induce RSB. L.A. on a leaf sheath was measured to calculate an C.V. Test Example 3 : Fungicidal activity against Cucumber Gray Mold Rot(CGM) disease Botrytis cinerae, which was isolated from cucumber infected thereby, was inoculated on a PDA agar medium and cultured under a 12L/12D cycle at 25 °C for 15 days to form spore. The spores were scraped, filtered through a gauze and then suspended in potato dextrose liquid medium at a concentration of lxlO 6 spore/ml. The spore suspension was sprayed on a cucumber plant having one leaf. The cucumber plant was held in a humidified room at 20 °C for 3 days. L.A. on a leaf was measured to calculate an C.V. Test Example 4 : Fungicidal activity on Tomato Late Blight(TLB) disease Phvtophthora infestans was cultured on a juice agar medium(V-8 juice 200 ml, CaC0 3 4.5 g, agar 15 g and distilled water 800 ml) under a 16L/8D cycle at 20 °C for 14 days. Sterilized water was added thereto, the vessel was shaken to free zoospore sacs from the fungus mass and the zoospore sacs were collected using a four-layered gauze. A zoospore sac suspension having a concentration of lxl0 5 spore/ml was sprayed on a young tomato plant. The tomato plant was held in a humidified room at 20 °C for 24 hours, transferred to an incubator maintained at a temperature of 20 °C and a relative humidity of more than 80% for 4 days and cultured in to induce RBC. L.A. on primary and secondary leaves was measured to calculate an C.V. Test Example 5 : Fungicidal activity against Wheat Leaf Rust(WLR) disease Puccinia recondita was subcultured on a wheat plant in a laboratory. 15 g of wheat seeds was sowed in a pot(diameter 6.5 cm) and cultured in a greenhouse for 7 days to obtain a wheat plant having only a primary leaf. The wheat plant was inoculated with spores by shaking thereover another plant infected thereby. The inoculated wheat plant was held in a humidified room at 20 °C for 24 hours, transferred to an incubator maintained at a temperature of 20 °C and a relative humidity of 70% and cultured for 10 days to induce WLR. L.A. on the primary leaf was measured to calculate an C.V. Test Example 6 : Fungicidal activity against Barley Powdery Mildew(BPM) disease Erysiphae σraminis was subcultured on a wheat plant in a laboratory. 15 g of barley seeds was sowed in a pot (diameter 6.5 cm) and cultured in a greenhouse for 7 days to obtain a barley plant having only a primary leaf . The barley plant was inoculated with spores by shaking thereover another plant infected by BPM. The inoculated barley plant was cultured in an incubator maintained at a temperature of 22 to 24 °C and a relative humidity of 50% for 7 days to induce BPM. L.A. on the leaf was measured to calculate an C.V. The results of subjecting the compounds of the present invention in Test example 1 to 6 at a concentration level of 250 ppm was more than 90% in most cases .
