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: Compositions and methods for their use are described for controlling parasitic fungi in and on plants containing, as active material, at least one compound corresponding to the formula ##STR1## in which R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5 and R.sub.6, which may be the same or different, represent hydrogen; halogen; nitro; alkyl, halo-alkyl or alkoxy carbonyl radical containing from 1 to 5 carbon atoms, andn = 0 or 1.The compositions are topically and systemically active and are applied to the susceptible plants, seeds, soil or its transportation or handling means and may be associated with an agricultural vehicle which facilitates its application. Compositions may also contain other agriculturally acceptable components including insecticides and other fungicides.

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: A method of treating and protecting plants from fungal infections by topical and systemic application with hypophosphites is described. The hypophosphites are selected from the group consisting of hypophosphorous acid (H.sub.3 PO.sub.2) and its salts with monovalent, and multivalent inorganic ions.

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.

Abstract: Fungicidal compositions containing as the active ingredient at least one compound of the formula, (RN).sub.6 P.sub.4, wherein R is an alkyl group containing 1 to 4 carbon atoms are disclosed, as well as a method of controlling fungus diseases of plants by applying such compositions.

Abstract: Fungicidal monoaminophosphite compositions are described. Methods of treatment of commercial plants susceptible to fungal infections such as mildew are described. The compositions are non-phytotoxic and are effective by systemic and topical application.

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: ##EQU1## 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.

Abstract: Fungicidal compositions, optionally contain chlorinated N- (2,4,6-trimethhenyl)-maleic imides as active material. Such materials find use for controlling fungus disease in plants, especially in agriculture, viticulture, arboriculture, market-gardening and horticulture.
