Fertilisation et sensibilité des cultures de tomate aux bioagresseurs

Abstract : Reducing dependence of crops on plant protection products has forced new ways of growing to be explored and the role of nitrogen in this context needs to be clarified in order to revise pratices. A specific study was therefore carried out over 3 years with the support of MAAP/DGER within the framework of the CASdar Fertipro which was approved by the GIS PIClég. It has revealed the mixed impact of nitrogen on tomato. The use of a management tool for soil nitrogen, such as PILazo®, has allowed nitrogen inputs to be reduced (by 30% minimum) having a positive effect on powdery mildew and maintaining yields, without exposing the crops to botrytis. Also, in soilless culture, the reduction and adaptive management of nitrogen rates throughout the growing season, thus reducing the risk of disease, have been validated.
