Pesticides in soils: persistence and impact on mycorrhizal systems
Pesticides are an integral part of intensive agriculture and are used to control what some consider to be weeds, fungal diseases or certain "pests". Over the past two decades, the use of pesticides has increased by more than 40%, and currently, more than 4.1 million tonnes are used worldwide each year . The intensive and widespread use of pesticides raises environmental and health concerns due to the contamination of natural resources. In fact, during their application, only a fraction of the pesticides applied achieve their objectives, the rest (30 to 50%) ending up on the soil surface and then dispersing through several abiotic processes.including volatilization, wind erosion, leaching or runoff.
