    • PURPOSE: A composition, containing a group of benzohydrol type compounds having trifluoromethyl group at the o-position as an active constituent, and capable of exhibiting high controlling effects on plants by the specific mode of action thereon.
      CONSTITUTION: A herbicidal composition containing a compound of formula I (R
      1 and R
      3 are H, lower alkyl, lower alkoxyl, halogen, amino or alkylamino), e.g. 2-trifluoromethyl-4'-methylbenzohydrol, as an active constituent. The compound of formula I acts more powerfully on the root part of the plants than on the terrestrial part thereof, and the root will not be completely formed when the degree of inhibition is large. Generally, the geotropism is lost, and the growth inhibition is caused at the same time. The compound of formula I is applied in an amount of 10W500g, preferably 20W100g, per are. The compound of formula I is obtained by subjecting a Grignard reagent of formula II (X is halogen) with an aldehyde of formula III to the Grignard reaction.

    • 目的:一种组合物,其含有一组在o位具有三氟甲基作为活性成分的苯甲醇型化合物,并且能够通过其上的具体作用方式对植物表现出高的控制作用。 构成:含有式I化合物(R1和R3是H,低级烷基,低级烷氧基,卤素,氨基或烷基氨基)的除草组合物,例如 2-三氟甲基-4'-甲基苯甲醛作为活性成分。 式I的化合物在植物的根部比在其陆生部分上更有力地起作用,当抑制程度大时,根不会完全形成。 一般地,地震性丧失,同时引起生长抑制。 式I化合物的用量为10-500g,优选为20-100g。 式I化合物是通过使式II的格利雅试剂(X为卤素)与式III的醛进行格氏反应而获得的。

    • PURPOSE:To provide the subject acaricide safe for human bodies and exhibiting a strong acaricidal or mite-repelling action against indoor-residing mites by containing L-(-)-menthol as an active ingredient and also provide the subject prescription capable of retaining the potency thereof for a long period by formulating the agent together with a drying agent. CONSTITUTION:An acaricide contains as an active ingredient L-(-)-menthol which is used for cosmetics, foods, medicines, etc., and is safe for human bodies. The active ingredient is mixed (kneaded) with a synthetic resin such as a thermosetting resin or thermoplastic resin in a state of the technical product, in a state included in cyclodextrin, etc., or in a state adsorbed on an adsorbable inorganic substance such as silica gel and subsequently molded into a sheet, pellets, etc., to provide an acaricidal formulation. The mixing ratio of the active ingredient with the resin is usually 0.1-99wt.%. The simultaneous use of the formulation with various drying agents can further give an acaricidal prescription having an excellent acaricidal activity due to their synergistic effect and capable of simultaneously carrying out also the moisture proofing of bedclothes.
