Novel acetal compounds of the formula: ##STR1## wherein X is a halogen atom, a trifluromethyl group or a lower alkyl group; Y is a halogen atom, a lower alkyl group or a lower alkyloxy group; m and n each independently are an integer of 0 to 2, and when m or n is 2, the plurality of each of X or Y may have the same or different meanings; R.sub.1 and R.sub.2 independently represent a saturated or unsaturated lower hydrocarbon residue, or R.sub.1 and R.sub.2 together form a substituted or unsubstituted alkylene chain which, when taken together with ##STR2## to which they are attached, form a ring structure, and a process for their production are provided. The compounds are highly effective against pathogenic fungi while being well tolerated by cultivated plants.

Fungicidal isonicotinanllide retals, their compositions and method of

A plant growth regulator containing as an active ingredient one or more compounds represented by the formula ##STR1## wherein R, X, Y and Z are defined in the specification is disclosed. The plant growth regulator is effective for a wide variety of plants, particularly for grassy plants. In addition to such activity, the regulator of this invention acts on plants to thicken the foliage and to aid health growth without causing substantial phytotoxicity.

Plant growth regulator

Isonicotinanilide derivatives of the formula ##STR1## (wherein R.sub.1 is a hydrogen atom or a lower alkyl group; X is a halogen atom or methyl; n is an integer of from 0 to 2; R.sub.2 is phenyl, halo-substituted phenyl or a lower alkyl group; and Q is ##STR2## provided that Q is ##STR3## or --CH.sub.2 --when R.sub.2 is phenyl or halo-substituted phenyl, and Q is ##STR4## when R.sub.2 is a lower alkyl group) a process for preparing the same and a plant growth regulator containing the same are disclosed. The derivatives of the formula above have good activity for regulating the growth of various plants, especially of grassy plants.

Isonicotinanilide derivatives, plant growth regulating compositions and

A pesticide containing an effective ingredient of a trialkyl isocyanurate of the formula: ##STR1## (wherein R is an alkyl group having 2 to 4 carbon atoms) which is optionally combined with a pyrethroid insecticide and a method of using the same are disclosed.
