Chromista
CLASSIFICATION
ABOUT
Chromista are fungus-like organisms, sometimes called water molds. They are mostly aquatic or soil-borne and cause many plant diseases (such as downy mildew and late blight).
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.
