Solanum elaeagnifolium

The silverleaf nightshade, Solanum elaeagnifolium is a perennial herb, covered with dense silver-whitish stellate trichomes, which give them its characteristic aspect. It belongs to a elaeagnifolium group of spp distributed in both South America and North America.

Widely distributed in Argentina together with two other species that belong to the elaeagnifolium group. It occupies elevated fields and disturbed areas, such as roadsides or construction sites. It is an important weed in cultivated fields and in grazing fields because it can be toxic to animals.

The silverleaf nightshade has been dispersed worldwide, mainly as a seed contaminant.

Two biological control agents, Leptinotarsa texana y L. defecta, from North America were released in South Africa.

In 2018 FuEDEI is starting a survey to record and study the associated insects in Argentina with the aim to obtain new biocontrolers.
