The disclosure belongs to the technical field of pesticides, and relates to an aminocarboxylic acid chelating agent with antifungal activity and synergistic use thereof with other sterilants. The aminocarboxylic acid chelating agent and salts thereof used alone or in combination can effectively inhibit growth and development of Fusarium, Botrytis cinerea, Pyricularia, Trichoderma, Penicillium and oomycetes with an effective antimicrobial concentration of 0.003-300 mM. They can effectively control wheat scab, rust disease, powdery mildew, rice blast, sheath blight, vegetable gray mold, sclerotinia and other fungal diseases. Combination with organic sulfur, antibiotic, benzimidazole, triazole, methoxyacrylate, succinate dehydrogenase inhibitor sterilants and oomcide drugs, can reduce amount of pesticides applied and improve control effects.

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.

The present invention provides fungicide combinations and compositions to improve the spectrum of plant disease control, with the use curative and preventive actives at a lower dosage. More particularly, the present invention provides a fungicidal combination comprising captan and a second fungicide. The present invention further provides methods of controlling and/or suppressing phytopathogenic fungi and maintaining crop health.
