SUMMARY Experiments in eastern England in 1975, 1977 and 1978 confirmed that endosulfan was an effective alternative to endrin for control of blackberry mite, Acalitus essigi (Hassan) (Acari: Eriophyidae), a cause of uneven ripening (‘redberry’) of blackberries. Three pre‐flowering sprays of 0 05 or 0–1 per cent endosulfan, applied at about 14‐day intervals, reduced the incidence of ‘redberry’ to an acceptable level; two sprays about four weeks apart were generally less effective. Endosulfan residues in fruits at harvest were below detectable levels. Carbaryl, chlorpyrifos, dicofol, vamidothion and ZR‐856 were not effective when tested in a preliminary trial in 1975.
