Abstract
A fungicidal composition which comprises a compound of general formula: ##STR1## or acid addition salts or metal complexes thereof, wherein R.sup.1 and R.sup.2 each independently represents a C.sub.1-5 alkyl group or a hydrogen atom; X represents a halogen atom, a C.sub.1-5 alkyl group or a phenyl group; n is 0, 1 or 2 and A represents a nitrogen atom or CH; and an aliphatic alcohol alkoxylate, for example an ethoxylate, with an average of 5-9 ethylene oxide units per molecule, of a C.sub.9-15 aliphatic alcohol, as adjuvant. It has been found that the presence of the alkoxylate substantially enhances the fungicidal efficacy of a compound of general formula I, in particular in foliar spray applications against fungi which are pathogenic to cereal crops.
Claims7
A fungicidal composition which comprises a compound of formula (I) ##STR4## or the acid addition salts thereof, wherein R.sup.1 and R.sup.2 each independently represents a C.sub.1-5 alkyl group or a hydrogen atom;
- X represents a halogen atom, a C.sub.1-5 alkyl group or a phenyl group;
- n is an integer of 0, 1 or 2;
- and A represents a nitrogen, atom or CH;
- and an alkoxylate of an aliphatic alcohol said alkoxylate being an ethoxylate or a mixed ethoxylate/propoxylate comprised of 5 to 25 alkoxy moieties wherein the enhanced weight ratio of the alkoxylate to the compound of Formula I is from about 5:1 to about 20:1.
