Provided is a plant disease control composition having a broad spectrum against various plant pathogens, and shows excellent controlling effects (synergistic controlling effects) which cannot be expected from a single component alone. The plant disease control composition includes (Group a) at least one quinoline compound represented by the formula: ##STR00001##
(wherein R.sup.1, R.sup.2: an alkyl which may be substituted, an aryl which may be substituted, etc.; R.sup.3, R.sup.4: H, an alkyl which may be substituted, etc.; X: halogen, an alkyl which may be substituted, etc.; Y: halogen, alkyl, etc.; n: 0 to 4; m: 0 to 6) or a salt thereof, and at least one of fungicidal compounds selected from the group consisting of a Strobilurin series compound, a triazole series compound, etc., as effective ingredients.

An environmentally compatible, pre-emergent herbicidal composition is provided that comprises a fertilizer seed meal and a transition metal chelate for enhancing the efficacy of the composition. The transition metals chelate can enhance, even synergistically effect the efficacy of the composition, while maintaining the selectivity of the herbicide.
