Silverleaf Nightshade - Australian Best Practice Management Manual 2018

Printer-friendly version
Silverleaf nightshade (Solanum elaeagnifolium) is a weed that reduces production in crop and pasture enterprises throughout the Australian wheat-sheep zone. It is a long-lived perennial plant with very deep, resilient roots. It grows during spring and summer and uses valuable moisture and nutrients needed for following crops and pastures.
Spread is relatively slow but, once established, it is extremely difficult to eradicate. Established dense infestations are an ongoing annual burden on productivity and costs, and there are no suitable effective herbicide treatments that will kill dense infestations quickly.
