Claims
- 1. A fungicidal composition for the protection of vines against fungus diseases, which comprises as the active material a mixture of:
- 1 part by weight of a monoester salt of a phosphorous acid of the formula ##STR3## in which R is an alkyl radical having 2 to 4 carbon atoms,
- Me is an alkali metal, alkaline earth, or aluminum atom and
- n is a whole number from 1 to 3 equal to the valence of Me
- and from about 0.2 to 0.5 parts of at least one phthalimide contact fungicide selected from the group consisting of N-(1,1,2,2-tetrachloroethylthio)-1,2,3,6-tetrahydrophthalimide and N-(trichloromethylthio)-phthalimide.
- 2. A composition according to claim 1 in which said contact fungicide is N-(trichloromethylthio)-phthalimide.
- 3. A composition according to claim 1 or 2 in which the alkyl phosphite is an ethyl phosphite.
- 4. A composition according to claim 1 or 2 in which the alkyl phosphite is a propyl phosphite.
- 5. A composition according to claim 1 or 2 in which the alkyl phosphite is an isopropyl phosphite.
- 6. A composition according to claim 1 or 2 in which the alkyl phosphite is a butyl phosphite.
- 7. A composition according to claim 1 in which the monoester salt of phosporous acid is aluminum ethyl phosphite and the contact fungicide is N-(trichloromethylthio)phthalimide.
- 8. A composition according to claim 7 in which the monoester salt of phosphorous acid is aluminum ethyl phosphite and the contact fungicide is N-(trichloromethylthio)phthalimide.
- 9. The composition of claim 1 which comprises aluminum ethyl phosphite and the contact fungicide N-(trichloromethylthio)phthalimide in a ratio by weight of said phosphite to said contact fungicide of about 1:0.5.
- 10. The composition according to claim 1 wherein the alkyl radical of said monoester salt of phosphorous acid contains 2 to 3 carbon atoms.
- 11. The composition according to claim 10 wherein the contact fungicide is N-(trichloromethylthio)phthalimide and is present in an amount of about 0.4 to 0.5 parts per part by weight of said monoester salt of phosphorous acid.
- 12. A fungicidal composition for the protection of vines against fungus diseases, which comprises as the active material a mixture of:
- 1 part by weight of a monoester salt of a phosphorous acid of the formula ##STR4## in which R is an alkyl radial having 2 to 4 carbon atoms,
- Me is an alkali metal, alkaline earth, or aluminum atom and
- n is a whole number from 1 to 3 equal to the valence of Me,
- and from about 0.2 to 0.4 parts of at least one phthalimide contact fungicide selected from the group consisting of N-(1,1,2,2-tetrachloroethylthio)-1,2,3,6-tetrahydrophthalimide and N-(trichloromethylthio)-phthalimide.
- 13. A composition according to claim 12 in which said contact fungicide is N-(trichloromethylthio)-phthalimide.
- 14. A composition according to claims 1, 2 or 10 in which Me is a cation selected from the group consisting of sodium, calcium, magnesium, and aluminum.
- 15. A composition according to claims 1, 2 or 10 in which said phosphite is aluminum or calcium ethyl phosphite.
- 16. A composition according to claim 10 or 12 which contains both of said contact fungicides.
- 17. A process for treating vines to protect said vines from fungal infection which comprises applying a composition defined in claims 1, 2 or 10 to said vines in an amount effective to control said fungal infection.
- 18. The process of claim 17 wherein the alkyl phosphite and contact fungicide are present in said composition in an amount such that about 50 to 400 g./hl. of alkyl phosphite and 20-400 g./hl. of the contact fungicide are applied to said vines.
- 19. The process of claim 17 wherein the fungal infection is mildew.
