| Abstract | Most physical and cultural weed control methods for arable crops do not provide complete weed control. Some weeds will escape the treatments and the numbers depend strongly on the successfulness of conducting the treatments. Moreover, current mechanical weed control methods, that work the intra-row area of the crop, generally operate with low selectivity whether it is cereals grown at narrow row spacing or typical row crops (e.g. maize, sugar beets, and many vegetables) at wider row spacing. Low selectivity means that a high weed control level might be associated with severe crop damages, particularly if large weeds are to be controlled satisfactorily. Thus, seeking for complete weed control can be very risky or more likely impossible. Since realising that, a number of investigations have then focussed on the tactical use of mechanical intra-row methods, particularly how they can be combined with cultural methods that mainly improve crop competitiveness and crop tolerance to withstand mechanical impact (uprooting and soil covering) from the weeding tools. Some promising weed control strategies in e.g. spring barley, onion, and pulse have been achieved from this work (e.g. Rasmussen & Rasmussen, 1995; Melander, 1998; Melander & Rasmussen, 2001; Rasmussen, 2002). Examples will be given here including results from very recent studies with mechanical and cultural weed control strategies in |
