A pesticidal composition comprising an inert carrier and, as active ingredient, an αβ-unsaturated carbonyl compound selected from:
(i) compounds of the formula I
wherein R1 is a phenyl group optionally substituted with 1 or 2 chlorine atoms, a naphthyl group or a furyl group optionally substituted by 1 or 2 methyl groups, R2 is a group selected from phenyl, furyl, thienyl, furfuryl, thien-2-ylmethyl or a group of the formula
(vi) 2-cyclohexenone; and
(vii) 5-phenyl-3-formyl-pyran-4-one.
The composition has use particularly in the treatment of pests such as insects and acarids.
The invention also provides compounds of formula I above wherein
R1 is 2-naphthyl and R2 is furfuryl; or
R1 is phenyl and R2 is fur-3-yl; or
R2 is fur-3-yl and R1 is 2,5-dimethylfur-3-yl; or
R1 is phenyl and R2 is 3,4-methylenedioxyphenyl.
