Diseases and pests that infect Datura
Datura avoids problems with large herbivores thanks to its poisonous leaves, but insects and diseases still attack it.
- Fungal diseases such as Septoria will spot the leaves. All datura species are among the septoria fungus host plants.
- Leaf spots that show rings inside them are most certainly due to Alternaria tenuissima, another leaf spot fungus.
- A few other fungus are responsible for root rot in this plant, such as Pythium (see a case where Pythium results in diseased Sunpatiens), Thielaviopsis and Phytoptora.
Viral diseases (sometimes spread by insects) may also contaminate Datura :
- mosaic viruses and others may result in leaves folding up and wilting.
Insects may also be to blame for spots and disease:
- Aphids are quite recognizable and can be seen with the naked eye. In addition to the damage they inflict, they also spread viral plant diseases.
- Whitefly requires a magnifying glass but can also be dealt with easily. They don’t usually spread diseases.
