Fluorobenzyl esters of the formula: ##STR1## wherein X represents the residue of any carboxylic acid of formula X-COOH which forms an insecticidally active ester with a 3-phenoxybenzyl alcohol, and R, R.sup.6 and R.sup.7 are each selected from hydrogen, halogen and alkyl of up to four carbon atoms, provided that at least one of R, R.sup.6 and R.sup.7 represents halogen, and further provided that R and R.sup.6 are not both bromine when R.sup.7 is hydrogen. The compounds are useful for combatting insect and acarine pests.
化学式为:##STR1## 的氟苯甲酸酯,其中X代表公式X-COOH的任何羧酸残基,该羧酸残基与3-苯氧基苯甲醇形成具有杀虫活性的酯,而R、R.sup.6和R.sup.7分别选自氢、卤素和碳数不超过四个的烷基,前提是至少有一个R、R.sup.6和R.sup.7代表卤素,而且在R.sup.7为氢时,R和R.sup.6不都是溴。这些化合物可用于对抗昆虫和螨类害虫。
