- Title
Chemical control of blackberry mite, Acalitus essigi (Hassan).

Alford, D. V.
- Abstract
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 005 or 01 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.
