| Abstract: | Leaves of Senecio jacobaea plants sprayed with 2,4-D had a higher water-soluble carbohydrate (WSC) content than unsprayed leaves 9–14 days after spraying. Insofar as WSC is a measure of palatability, this implies an increased risk of Senecio poisoning in grazing cattle for more than 14 days after spraying with growth regulator herbicides. Total unsaturated pyrrolizidine alkaloid content may also be increased by 2,4-D, making the plant more toxic. |
