In Swedish grasslands, eight species that had not been observed in the extant vegetation for 35 yr were found in the soil seed bank (Milberg, 1992), indicating that viable seeds may have been in the soil for at least 35 yr. Fibre flax. Holm LG; Pancho JV; Herberger JP; Plucknett DL, 1991. On the other hand, application of molybdenum to soil where plants of T. aestivum were growing reduced preharvest sprouting, but if phosphorus was applied along with molybdenum there was an increase in germination percentage (Modi, 2002). Due to the variable regulations around (de)registration of pesticides, your national list of registered pesticides or relevant authority should be consulted to determine which products are legally allowed for use in your country when considering chemical control. There are a number of reasons why some plant species have been more successful as weeds than other plants. Sîrbu M; Slonovschi V, 1989.

Although effective for the control of other weeds, harrowing in the dark showed no significant influence on emergence of F. convolvulus seedlings in comparison to daylight harrowing in Swedish field trials (Ascard, 1992). The distribution in this summary table is based on all the information available. Magnoliphyta: Caryophyllidae, Part 2 [ed. Seeds from plants of Viola elatior grown at 5 and 20 g nitrogen m−2 yr−1 germinated to 35 and 67%, respectively, whereas those from plants of V. pumila germinated to the same percentages (about 90) regardless of the nitrogen level mother plants received (Eckstein and Otte, 2004).
