CLASSIFICATION
Chromista, Peronosporea
ABOUT
Pathogens from the Peronosporaceae family are fungi-like water molds causing infectious plant diseases called downy mildews. They form typical spores-containing structures on the downside of the leaves.
How to treat?
- Biological
If possible remove and destroy the infected parts of the plant. Burn it, toss it into the garbage, or bury it deeply. Do not compost.
If the infection is widespread, remove and destroy the infected plant. Burn it, toss it into the garbage, or bury it deeply. Do not compost.
- Disease prevention
Use resistant species and cultivars as well as healthy, certified seeds and seedlings.
Rotate crops. Avoid planting sensitive crops in infested soil.
Ensure having good soil drainage to avoid overwatering.
Disinfect tools, infected flower pots, and hands to avoid disease transmission.
If necessary, use chemical products as a prevention (e.g. copper-based spray). These chemicals may lead to the development of resistant strains.
