Evaluation of various mechanical measures on weed control efficacy

Summary

The current paper presents results from an investigation of simulation of various mechanical measures in weed control which was conducted in pot trials in a growth chamber between 2001 and 2002. Simulation of nine different systems of mechanical control with five weed species chosen for their different growth habits and subsequent regrowth capabilities was compared. The trial was conducted on two dates in relation to weed size and under wet and dry growth conditions. It could be found out that the effectiveness of mechanical measures depended on weed size and on soil moisture by the time of carried out measures. The best results were obtained when mechanical measures were taken earlier, i.e. when broad-leaved weeds had 2–3 pairs of true leaves and grasses had 2–3 leaf-blades, and under dry conditions which prevented the subsequent regrowth and development of damaged weeds.

Key words: Weeds; weed control, mechanical measures.
