Description	The aim of this work was to compare the efficacy, selectivity to sunflower and dissipation of three chloracetamide herbicides (acetochlor, metolachlor and pethoxamid) in dependence on precipitation after application. A small plot field trial was carried out in sunflower in Middle Bohemia in 2010 and 2011. The remaining concentration of active ingredient in the soil of all studied herbicides was lower in the year with a higher temperature and a low level of total natural precipitation at the beginning of the growing season. Higher leaching of metolachlor and pethoxamid was recorded in irrigated plots. No leaching was found in the case of acetochlor. The highest leaching was found for metolachlor (9.2-25.5 % in soil layer 0.05-0.1 m). The highest phytotoxicity was found for acetochlor (9.8 %) > pethoxamid (4.6 %) > metolachlor (1.8 %). The mean phytotoxicity in the irrigated plots was 6.9 %, compared with 3.9 % in the non-irrigated plots. The efficacy of the tested herbicide was affected by wet conditi The aim of this work was to compare the efficacy, selectivity to sunflower and dissipation of three chloracetamide herbicides (acetochlor, metolachlor and pethoxamid) in dependence on precipitation after application.
