This invention provides alkoxy acetic acid derivatives of general formula I: ##STR1## wherein R is the residue of an amine, an aminoalcohol or a polyol linked to the or each --CHR'--CO-- moiety via an amide or ester linkage;

Alkoxy acetic acid derivatives

Biocidal compositions comprising novel azophenyl compounds which are suitable as fungicidal agents are provided which comprise a carrier and, as active ingredient, a compound of the general formula

Biocidal azophenyl compositions

Compounds of the general formula ##STR1## where R.sup.2 and R.sup.3 together, or R.sup.3 and R.sup.4 together, represent an optionally substituted hydrocarbyloxy chain; the ring is optionally substituted at any or each of the remaining sites R.sup.5, R.sup.6 and R.sup.2 or R.sup.4 : n represents 0 or 1; and X represents a cyano group, a group --COOH or a salt, ester or amido derivative thereof; are biocidal, showing activity against fungi, yeast, bacteria and nematodes. Some such compounds, and intermediates therefore, are novel.

Bicyclic or tricyclic biocidal compounds

The invention provides compounds of general formula ##STR1## wherein m is 0 or 1; each of R.sup.1 and R.sup.2, and R.sup.3 and R.sup.4 if present, independently represents a hydrogen or halogen atom or an optionally substituted alkyl, cycloalkyl or aryl group, or R.sup.1 and R.sup.2 together or R.sup.3 and R.sup.4 together represent an optionally substituted alkylene chain; X represents a cyano group, a group --COOH or a salt, ester or amido derivative thereof; Y represents an alkyl group or a halogen atom; and n represents 0, 1, 2 or 3; a process for their preparation; compositions containing such compounds and their use as fungicides.

Biocidal compounds

Biocidal azophenyl compounds

Novel compounds of the general formula ##STR1## where R represents an optionally substituted aryl or heteroaryl group; X represents a hydrogen atom or an amino group or an optionally substituted alkyl, aryl or heteroaryl group; and Z represents a hydrogen atom or alkanoyl group; are fungicidal.

Fungicidal phenyl azoxime compositions

Use as agricultural fungicides of N-acyl-N-hydroxyalkanoic acid compounds of the formula ##STR1## and salts thereof, wherein each of the symbols has an assigned meaning.
