| A trial was established in 2003, in Southern France, to assess under organic farming conditions the effect of top irrigation with sprinklers on potato yield, but also to evaluate side effects on epidemics, with a focus on late blight (Phytophthora infestans L.). Two varieties, one susceptible (Charlotte) and one with a good level of resistance to late blight (Eden), have been planted. Three irrigation regimes have been applied : no irrigation [NO], reduced or optimized irrigation [OPT] and irrigation according to usual grower practice [NORM]. Irrigation had no effect on foliar late blight development. For both varieties, commercial yield in the non-irrigated plots was significantly lower (16,36 t.ha-1) than in the OPT and NORM plots (resp. 26,12 t.ha-1 and... |

| In Europe, the pervasive use of pesticides in agricultural areas has led to the deterioration of the quality of groundwater and surface water, resources earmarked for human consumption. The aim of the European Water Framework Directive 91/474 is to restore the “good ecological status” of surface water and to protect water that might be used for drinking water production by 2015. Interactions within the soil determine the fate of environmental pesticides. Water resource contamination may persist for a long time after the last use of pesticides (i.e., atrazine). Pesticide persistence is highly variable. The fate and persistence of pesticides in the environment depend on agricultural pesticide practices and on soil interactions, which are interrelated... |
