Abstract: Hydantoin-based derivatives having herbicidal activity are provided to selectively control weeds without harmful effects to useful crops such as corn, and prevent environmental pollution by reducing the use amount of herbicides. The hydantoin-based derivatives having herbicidal activity, represented by the formula(1) are provided, wherein n is an integer from 0 to 3; R1 is hydrogen atom, C1-C6 alkyl group, C1-C6 haloalkyl group, C2-C6 alkoxyalkyl group, C1-C6 hydroxyalkyl group, C2-C6 alkenyl group or C2-C6 alkynyl group; R2 is hydrogen atom, C1-C6 alkyl group, C1-C6 haloalkyl group, C2-C6 alkenyl group or C2-C6 alkynyl group; and X is hydrogen atom, halogen atom, cyano group, hydroxyl group, C1-C4 alkyl group, C1-C4 alkoxy group, C2-C4 alkenyl group, C2-C4 alkynyl group, C2-C4 alkoxyalkyl group or C1-C4 hydroxyalkyl group. The hydantoin-based derivatives having herbicidal activity, represented by the formula(1) are prepared by halogenization of hydantoin carboxylic acid represented by the formula(2) to prepare compounds represented by the formula(4), and reacting the compounds represented by the formula(4) with compounds represented by the formula(3). A herbicidal composition comprises the hydantoin-based derivatives having herbicidal activity, represented by the formula(1).

Abstract: PURPOSE: A composition containing an extract of Rumex crispus or Rumex japonicus obtained by extracting in methanol and then successively extracting in various organic solvents is provided. Therefore, the composition is effective in eradicating the causative agent of powdery mildew on crops such as Sphaerotheca fuliginea, Blumeria graminis. CONSTITUTION: Rumex crispus or Rumex japonicus is extracted in 80% methanol, the extract is concentrated under reduced pressure, dissolved in 80% methanol and extracted in hexane. Then, the extract is dissolved in 80% methanol, concentrated under reduced pressure, extracted in ethyl acetate and then concentrated under reduced pressure. The composition for controlling powdery mildew contains the extract in the range of 0.0037 to 0.3g/ml, preferably 0.011 to 0.3g/ml, based on the weight of raw material. For an example, the Rumex crispus or Rumex japonicus extract shows a control value of 60 to 100% against barley powdery mildew.

Abstract translation: 目的：提供含有通过在甲醇中提取，然后在各种有机溶剂中连续萃取而得到的Rumex crispus或Rumex japonicus提取物的组合物。 因此，该组合物有效地消除白粉病的致病因子对作物如白纹霉（Sphaerotheca fuliginea），Bl螨（Blumeria graminis）的作用。 构成：将Rumex crispus或Rumex japonicus在80％甲醇中萃取，将提取物减压浓缩，溶于80％甲醇中，用己烷萃取。 然后将提取物溶于80％甲醇中，减压浓缩，在乙酸乙酯中萃取，然后减压浓缩。 基于原料重量，用于防治白粉病的组合物含有0.0037〜0.3g / ml，优选为0.011〜0.3g / ml的提取物。 例如，对于大麦白粉病，Rumex crispus或Rumex japonicus提取物显示出60至100％的对照值。
