Processes for producing phenoxy propionic acid derivatives

Methods for producing pyrimidine compounds

A novel 3(2H)-pyridazinone derivative of the formula [I]: ##STR1## wherein, R represents an alkenyl group having 2 to 16 carbon atoms, an alkynyl group having 2 to 16 carbon atoms, an alkyl group having 3 to 8 carbon atoms substituted by an alkoxy group having 1 to 6 carbon atoms or G-Ra-;

3(2H)-pyridazinone compounds derivatives and compositions for

A nitrogen-containing heterocyclic compound of the following formula: ##STR1## wherein D represents --N.dbd. or ##STR2## E represents .dbd.N--, ##STR3## G represents --N.dbd., ##STR4## with proviso that when G represents --N.dbd. or ##STR5## the bond of G and E is double bond; and G represents ##STR6## the bond thereof is a single bond, but the case that D represents ##STR7## E represents ##STR8## and G represents --N.dbd. is omitted (R.sup.1, R.sup.2, R.sup.9, R.sup.10, X, Y, A and Q are specified in the specification), as well as compositions for controlling and/or preventing pests and blights, said compositions containing one or two or more of said compounds as an active ingredient.

Nitrogen-containing heterocyclic compounds and compositions for
