Models of emergence of nineteen weed species


, : Models of emergence of nineteen weed species. Malezas 8(2): 3-11

Diagrammatic models of weed flushes, taking into account the effect of seedbed preparation, have been constructed for 19 species, using data obtained from observations over 3 consecutive years. The species are classified into 4 groups: (1) a summer-autumn flush including Capsella bursa-pastoris and Sonchus oleraceus; (2) an autumn-winter flush (in this group some species peaked in autumn, e.g. Stellaria media and Anthemis cotula, some in winter, e.g.
