     2. DESCRIPTION OF THE PRIOR ART 
     Even though the known fungicides possess excellent fungicidal properties, the development of compounds based upon a similar basic structure has given rise to the problem of resistance development by the target fungi due to long exposure to these compounds with a common basic structure. 
     As a result of a continuous effort to solve this problem, a series of novel propenoic ester derivatives was disclosed firstly in European Patent No. 472300 of ICI Co., U.S. Pat. No. 4994495, European Patent No. 422597 of BASF Co., U.S. Pat. No. 5003101 and European Patent No. 460575 of Ciba-Geigy Co., but the fungicidal activity of the reported compounds was too low and limited in its application therefore, there is a need for potent fungicides which possess effective fungicidal activity, low toxicity and good economy. 
     Therefore, in consideration of the aforesaid points, the present inventors have made efforts to develop new fungicidal compounds which have powerful fungicidal activities to various target fungi and low toxicity, we have applied for a patent about propenoic ester derivatives having a pyrazole group and the use thereof (Korean laid-open patent No. 94-432, PCT/KR93/00052). 
     As the result, the inventors of the present invention synthesized novel propenoic ester derivatives by using 4-hydroxypyrazole compounds which have not been so far known. 
     SUMMARY OF THE INVENTION 
     The objective of the present invention is to provide novel propenoic ester derivatives with strong fungicidal activities toward various fungi and broad fungicidal spectrum and a simple manufacturing process. 
     Another objective is to provide fungicidal compositions containing the derivatives as an active compound. 
     DETAILED DESCRIPTION OF THE INVENTION

     In the formula(I) according to the present invention, the preferred derivatives with greatest fungicidal activities are those where R 1  and R 4  represent hydrogen, R 2  represents a methyl or methylthio group, R 3  represents a phenyl or substituted phenyl group which is substituted by a substituent selected from the group consisting of an alkyl group having 1 to 6 carbon atoms, and an alkoxy group having 1 to 6 carbon atoms, and R 5  represents a trifluoromethyl or methyl group. 
     According to the present invention, propenoic ester derivatives of the above formula(I) can be prepared by the following two methods. 
     As shown in the following reaction pathway 1, the first method is the preparation of propenoic ester derivatives of the above formula(I) by reacting propenoic benzyl bromide of the following formula(II) with 4-hydroxypyrazole of the following formula(III) in the presence of an appropriate base. 
      Reaction Pathway 1! ##STR4##

     In the above reaction, the compounds of formula(II) are reacted with the same mole of the compound of formula(III) in the presence of 1-3 equivalents of base. 
     Additionally in the above reaction, an organic solvent such as chlorobenzene, tetrahydrofuran, dimethylformamide or dichloroethane and base such as potassium carbonate, sodium hydride, triethylamine or pyridine may be used. The completion of the reaction for obtaining the compound of formula(I) is when no more compound of formula(II) remains, and it can be easily checked by T.L.C. 
     The compounds of formula(II) and formula(III) in the above reaction pathway can be easily prepared by the well known reaction pathway that formylation, alkylation and bromination using substituted o-tolylacetic acid as starting material  Reference: The compound of formula(II); 1.

In the case of the reaction of alkoxylamine, dichloromethane, 1,2-dichloroethane, ethyl alcohol or pyridine are desirable to be used as an organic solvent. The completion of reaction is realized when the compound of formula(IV) no longer remains in the reaction, and it can be easily checked by T.L.C.

     The superior fungicidal activities of propenoic ester derivatives(I) according to the present invention prepared by die above examples were tested to check protective effect against the barley powdery mildew, the wheat leat rust, the rice blast and rice sheath blight. A 10% acetone solution containing the compound(I) was diluted using a Tween-20 solution of 250 ppm strength(500 ppm in the case of rice). 500 ml of this chemical solution was sprayed to plants of equal height and allowed on to stand at room temperature for 24 hours. After evaporation of the spray solution and water, the test plants were inoculated with target fungi. The tests were carried out two times by the same method. 
     In the case of a fungicidal rate of 100%, the concentration of the test chemicals was gradually reduced until the EC 50  value, namely the concentration (ppm) which gives a fungicidal rate of 50% was determined. 
     TEST 1 
     Fungicidal Test for Rice Blast (RCB) 
     Pyricularia oryzae Cavara KJ301 as test rice blast fungus was selected and inoculated on rice polish agar medium(Rice polish 20g, Dextrose 10g, Agar 15g, Distilled water 1 l) to incubate at 26° C. for 2 weeks, and then scratched airial mycelia with Rubber Polishman were irradiated with near fluorescent light to form spores at 25°˜28° C. for 48 hours. 
     A suspension of conidia in water(10 6  spores/ml) was prepared and sprayed upon the 3˜4 leaf stage of rice plants on the foliage. After placing in a dark dew chamber for 24 hours, the treated plants were then held in a lighted growth chamber(26±2° C., 80%) for 5 days, and rated on the disease severity. The disease severity was examined against the percent disease area on the first leaf right under 3˜4 leaf stage and compared to the standard rating diagram. 
     TEST 2 
     Fungicidal Test for Rice Sheath Blight (RSB) 
     Rhizoctonia solani AG-1 was incubated in wheat bran medium (1 l, bottle), and then the agar disc was inoculated in a growth chamber(27±1° C.) for 7 days. 
     Rice plans in the 2˜7 leaf stage in 5 cm pots were inoculated with the milled conidia. After incubating in a dew chamber(28±1° C.), the disease severity was examined against the percent disease area on the applied leaf of 2˜3 leaf stage and compared to the standard rating diagram. 
     TEST 3 
     Fungicidal Test for Wheat Leaf Rust (WLR) 
     Test was made to succession culture of Puccinia recondita against the host plants. For the succession culture and the fungicidal effect test, wheats(cultivar; chokwang) were grown in polyvinyl pots(diameter; 6.5 cm) for 7 days, and then spores of the first leaf stage were inoculated. 
     After placing the treated wheat in a dew chamber at 20° C. for 1 day, the plants were held in a growth chamber (20° C., 70%) for 10 days, and then rated on the disease severity. 
     The disease severity was examined as the percent disease area after inoculating the spores for 10 days. 
     TEST 4 
     Fungicidal Test for Barley Powdery Mildew(BPM) 
     Tests were made to succession culture of Eysiphe graminis &amp;. sp. hordei. For the succession culture and the fungicidal effect tests, barley(Dongbori No. 1) was grown in polyvinyl pots(diameter; 6.5 cm) for 7 days, and then spores of the first leaf stage were inoculated. 
     The treated barley was held in a growth chamber(22˜24° C., 50%), and the disease severity was rated alter 7 days inoculation. 
     In the above Test 1˜4, those compounds which produced a an fungicidal rate of 100% at 500 ppm and, for comparison, commercial fungicidals (controls) were tested according to the method mentioned above, and the EC 50  values were determined. The results are shown in Table 2. 
     EC 50  value means the concentration(ppm) at which a fungicidal rate of 50% is.
