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 use of a one or more Isoflavonoid compound Signals which may be with an agriculturally acceptable carrier, applied prior to planting, up to 365 days or more, either directly to the seed or transplant of a non-legume crop or a legume crop, or applied to the soil that will be planted either to a non-legume crop or a legume crop, for the purpose of increasing yield and/or improving seed germination and/or improving earlier seed emergence and/or improving nodulation and/or increasing crop stand density and/or improving plant vigour and/or improving plant growth, and/or increasing biomass, and/or earlier fruiting, all including in circumstances of seedling and plant transplanting.

The present invention about using chemicals to interfere with the ability of certain arthropods to shield themselves from their external environment. It teaches to apply chemicals to a specialized portions of the arthropod's body that maintain a gaseous envelope that encoats, protects and extends from the arthropod's skin and, if present, breathing hole. This chemical application causes a failure of this protective envelope, making the arthropod vulnerable its external environment such as to pesticides and can also lead to problems with its ability to breathe.
