The biology and non-chemical control of Field Forget-me-not (Myosotis arvensis (L.) Hill.)

Occurrence Field forget-me-not is a native winter or summer annual, biennial or perennial weed found in open, cultivated and well-drained ground including gardens, roadsides, on dunes and in woods (Stace, 1997; Clapham et al., 1987). It is common throughout the UK and is recorded up to 1,600 ft (Salisbury, 1961). In an early survey of Bedfordshire and Norfolk it was of universal occurrence but was found chiefly on sand and loam soils and rarely on chalk (Brenchley, 1913). It is an indicator of loam (Hanf, 1970). In Europe it shows a preference for soils with low pH (Holzner & Immonen, 1982).
