Claims23
A composition for controlling phytopathogenic fungi without causing a significant increase in phytotoxicity which comprises a fungicidally effective amount of a compound having the structural formula ##STR2## wherein R is C.sub.1 -C.sub.3 alkyl, allyl, propynyl, ethylcarboxymethyl, phenyl or benzyl;
- Y, Y.sub.1, Z and Z.sub.1 are each independently hydrogen, halogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy;
- X is an anion having a charge of 1 or 2;
- and
- m is an integer of 1 or2, and "an enhancing effective amount of an oil selected from the group consisting of a mineral oil, a vegetable oil, an animal oil and mixtures thereof".
A method for the control or amelioration of a disease caused by a phytopathogenic fungus without causing a significant increase in phytotoxicity which comprises contacting said fungus with a fungicidally effective amount of a composition which comprises a compound having the structural formula ##STR3## wherein R is C.sub.1 -C.sub.3 alkyl, allyl, propynyl, ethylcarboxymethyl, phenyl or benzyl;
- Y, Y.sub.1, Z and Z.sub.1 are each independently hydrogen, halogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy;
- X is an anion having a charge of 1 or 2;
- and
- m is an integer of 1 or 2, and "an enhancing effective amount of an oil selected from the group consisting of a mineral oil, a vegetable oil, an animal oil and mixtures thereof".
A method for the protection of a crop, crop seed or tuber from fungal infestation and disease which comprises applying to the crop, crop seed or tuber, or to the medium or water in which it is growing, a fungicidally effective amount of a composition which comprises a compound having the structural formula ##STR4## wherein R is C.sub.1 -C.sub.3 alkyl, allyl, propynyl, ethylcarboxymethyl, phenyl or benzyl;
- Y, Y.sub.1, Z and Z.sub.1 are each independently hydrogen, halogen, C.sub.1 -C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy;
- X is an anion having a charge of 1 or 2;
- and
- m is an integer of 1 or 2, and "an enhancing effective amount of an oil selected from the group consisting of a mineral oil, a vegetable oil, an animal oil and mixtures thereof".
