Abstract: The present invention relates to a plant disease control agent containing a compound represented by the following formula (1) or salt thereof as an active ingredient (in the formula, R1 and R2 represents a hydrogen atom or methyl group but excepting cases where R1 and R2 are the same), a plant disease controlling method applying the plant disease control agent on plants suffering from diseases, and a novel compound represented by formula (1) or salt thereof.

Abstract: An agricultural and horticultural fungicide composition including prumycin and a surfactin family member as active components and a plant disease controlling method. As the surfactin, family member, surfactin and [Ile7]surfactin are preferred. The composition preferably further contains calcium chloride comprises for improving storage stability.

Abstract: The present invention provides a novel agricultural and horticultural fungicide composition including prumycin and a surfactin family member as active components and a plant disease controlling method. As the surfactin, surfactin and [Ile7]surfactin are preferred. The present invention provides a practically useful agricultural and horticultural fungicide composition having a high effect and excellent storage stability, which composition further comprises calcium chloride so as to remarkably improve the storage stability thereof.

Abstract: The present invention relates to a microbial pesticide composition, which is obtained by a method including the steps of: adjusting a pH of a culture solution of the Bacillus sp. bacterium to from 3.0 to 5.0 (pH adjustment step); mixing the culture solution with the calcium chloride and/or the magnesium sulfate (mixing step); and lyophilizing or spray-drying the culture solution (drying step). In the microbial pesticide composition, even if it is stored for a long period of time at room temperature, the active ingredient remains stable and a sufficient preventive effect against plant disease can be maintained.

Abstract: An apparatus for continuously forming a glass-ceramic which melts raw materials and forms melted glass to a predetermined shape without cutting the melted glass and thereafter continuously crystallizes the formed glass to the glass-ceramic is provided.

Abstract: According to one aspect of the invention, there is provided glass for a photomask consisting, in weight percent, of 45 to 62% SiO.sub.2, 3 to 15% B.sub.2 O.sub.3, 12 to 25% Al.sub.2 O.sub.3, 5 to 15% MgO, 0 to 5% CaO, 0 to 5% SrO, 0 to 5% BaO, 0 to 5% ZnO, 0.5 to 5% PbO, 0 to 20% La.sub.2 O.sub.3 +Gd.sub.2 O.sub.3 +Y.sub.2 O.sub.3, 0 to 1.5% Na.sub.2 O, 0 to 1.5% K.sub.2 O, 0 to 0.5% As.sub.2 O.sub.3 and 0 to 6% Sb.sub.2 O.sub.3. This glass is easy to melt and homogenize and has good resistivity to phase separation and excellent heat resisting and refractory properties, chemical durability, ultraviolet transmittance and metal vapor deposition property. According to another aspect of the invention, there is provided glass for a photomask consisting, in weight %, 45 to 60% SiO.sub.2, 0.5 to 12% B.sub.2 O.sub.3, 10 to 22% Al.sub.2 O.sub.3, 5 to 17% MgO, 0 to 5% CaO, 0 to 8% SrO, 1.5 to 15% BaO, 1.5 to 17% ZnO, 0.5 to 10% PbO, the total content of ZnO and PbO being at least 6%, 0 to 7% Ta.sub.2 O.sub.5 +Nb.sub.
