摘要:
A tetrahydrofuran derivative represented by the following general formula [I]: ##STR1## [wherein A represents direct bonding or a group represented by --B--CHR.sup.1 -- (wherein B represents oxygen atom, sulfur atom or imino group; R.sup.1 represents hydrogen atom or an alkyl group); R represents hydrogen atom, halogen atom, hydroxyl group, an alkoxy group, benzyloxy group, an alkylsulfonyloxy group or a group represented by --O--COR.sup.2 (wherein R.sup.2 represents an alkyl group, a haloalkyl group, an alkenyl group, a cycloalkyl group, phenyl group, benzyl group, an alkoxy group, an alkylamino group or a dialkylamino group; X represents halogen atom; Y represents hydrogen atom or halogen atom) and the herbicide containing the same as the effective ingredient. The compounds of the present invention have exceedingly high herbicidal activity, and furthermore, the compounds are superior to the known similar compounds in terms of safety on crops. Thus, the compounds are useful as herbicides.

摘要:
The present invention relates to the use of thiadiazoles of the type ##STR1## in which R.sub.1, R.sub.2 and R.sub.3 =hydrogen,alkyl groups having 1-4 carbon atomssubstituted alkyl groups having 1-4 carbon atoms which are substituted by halogen, carboxyl, hydroxyl or nitro group,an alkoxyCN, halogen, NO.sub.2 orCOOR in which R=H or alkyl groups 1-4 carbon atoms,and the use of synergistic combinations of thiadiazoles with other biocidal substances as biocides for material protection. The compounds according to-the invention, which are distinguished by a broad, biocidal action spectrum, can be used in particular for wood preservation for preventing the destruction of wood by fungi or bacteria, for the biocidal treatment of plastics and as preservatives or disinfectants. The recommended concentrations for use are 0.01 to 15 percent by weight-preferably 0.1-3.0 percent by weight.

摘要:
Insects, especially sucking insects, such as brown planthoppers, and phytophageous mites, such as two-spotted spider mites, are controlled by applying an oxadiazole or thiadiazole compound substituted on a carbon atom by an aliphatic nitrogen heterocyclic moiety composed of at least one five or six membered ring. The compound 3-(3-amino-1,2,4-oxadiazol-5-yl)-1-azabicyclo[2,2,2]octane is typical.
