Autumn 2026 sees an increased presence of datura, a particularly toxic invasive plant for humans and animals, in the Isère region. Farmers are urged to be vigilant against this threat.
The toxicity of datura is such that a single plant per 25m² can cause a fatal intoxication in cattle, particularly through silage corn. This year, the plant has also been observed in some pastures affected by drought in the south of the department.
In response to this situation, controlling the spread of datura is deemed essential. The most effective method remains uprooting upon first detection. Plants must be pulled out with gloves and left in place. The seed pods should be cut off and disposed of in a trash bag.
The Chamber of Agriculture of Isère, through Canelle LAISNE, agronomy and environment advisor, emphasizes the importance of taking the presence of this plant seriously and implementing necessary measures to curb its dissemination.
