SUMMARY Pyrazophos was more effective than dioxanthion against chrysanthemum leaf miner ( Phytomyza syngenesiae Hardy) when applied as a mist onto bed‐grown plants irrespective of the stage of development of the pest. When pyrazophos was applied at the feeding mark stage no eggs developed but when it was applied at the young mine, mature mine or pupal stages 3–5%, 3‐1% or 45‐5% reached adulthood. Pyrazophos applied every 17‐5 days kept damage levels acceptably low. The potential of pyrazophos within an integrated control programme for chrysanthemum is discussed.
