Abstract: The pre-emergence or post-emergence treatment for weed control in dicotyledonous crops with N-(4-isopropylphenyl)-N',N' dimethylurea and method for crop treatment.

Abstract: Compositions are described which are suitable for use in controlling parasitic fungi, especially mildews, in plants and which contain as their active material at least one compound corresponding to the general formula: ##STR1## in which R and R', which may be the same or different, represent a linear or branched alkyl radical of 1-18 carbon atoms, which may optionally be substituted, preferably by halogens or hydroxy groups, an optionally substituted cyclohexyl or phenyl radical; a heterocyclic radical connected to an oxygen atom adjacent the phosphorus by an aliphatic chain of 1 or 2 carbon atoms.

Abstract: Fungicidal compositions containing phosphorous acid, inorganic and organic salts thereof are disclosed, as well as a method of controlling fungus disease in plants by applying such compositions.

Abstract: Fungicidal compositions for controlling fungus diseases in plants are disclosed. These compositions contain as their active materials compounds and polymers thereof corresponding to the formula: ##STR1## in which Y', Y", Z' and Z" represent a hydrogen atom or an optionally halogenated alkyl radical containing from 1 to 5 carbon atoms. Included within these active materials are the hydrolysates, salts and quaternary salts of these phospholanes. These cyclic phospholanes or phosphites and their hydrolysates are compatible with other commercial fungicides and the compositions disclosed include these compounds above and in combination with such other fungicides.
