Attempts at Cultural Control of Carrot Fly Damage to Carrots in East Anglia

Abstract

SUMMARY At sites in Norfolk in 1970, 1971 and 1972, growing carrots were covered in situ with soil or straw for varying periods in attempts to prevent egg laying and subsequent late‐season damage by larvae of the carrot fly (Psila rosae) (F.))‐ Neither soil nor straw was sufficiently effective in this respect. Carrots chemically defoliated and/or covered during the main egg‐laying period in August and September were adversely affected in size and quality.
