Certain embodiments comprise extracting glucosinolates from plant material, or processed plant material, selected from the family Brassicaceae, particularly from the generaand. Extracted glucosinolates can be hydrolyzed to form active compounds, or alternatively, they can be hydrolyzed in situ, by simultaneously or sequentially applying myrosinase. The extract can be applied to plants, to the soil adjacent to the plant.
