Overview of diseases and pests of the Pimpinelle
Downy mildew: the harmful "bad weather mushroom"
] The downy mildew is one of the "bad weather mushrooms" that feel comfortable in a humid environment. They recognize the infestation on a white or gray coating on the undersides of the leaves. In addition, the leaf tops may be brown, orange or violet discolored. If not treated, the symptoms spread to flowers and stems and eventually destroy the pimples.
Prevent and actively fight
The correct preventive measures do not provide complete but very extensive protection of the pimples against downy mildew. What should I do?
- Do not use fertilizers that are concentrated in nitrogen but potassium
- maintain generous plant and row spacing of 30 centimeters
- Do not plant Pimpinelle in full shade
- Do not plant pimples in damp locations
- irrigate the soil, do not water the leaves of the pimpinelle
In spite of these measures, if you find mildew on the pimpinelle, you can use effective fungicides that are also suitable for herbs and vegetables. Adhere strictly to the manufacturer's recommendations. As biological alternatives, for example:
- Nettle brew
Aphids: the sucking pests
Aphids feed on plant sap. They inflict suction damage on the leaves of the pimpinelle, which they recognize as yellow discoloration. In addition, aphids leave their excrement as sticky honeydew on the pimpinelle. In case of persistent infestation, the leaves wither and eventually collapse. The tiny aphids themselves, when looked closely, can be recognized as green, gray, yellow or black spots on the underside of the leaves.
Prevent and actively fight
Make life difficult for aphids around your Pimpinelle in the following ways:
- Reproduction possibilities for beneficial organisms (deadwood hedges, lacewing boxes)
- Plant and row spacing of 30 centimeters
- Do not plant pimpinels in monoculture
- Grow plants with essential oils such as lavender in the neighborhood
- fertilize with potassium
Discover aphids on the pimpinelle, shower vigorously. As astonishing as it sounds, the return path is almost insurmountable long for a flightless aphid, which was sprayed only 25 centimeters away from the Pimpinelle. In addition, remove all visible leaves glued by honeydew. Rapeseed oil-based preparations and potash teas are an effective and beneficial in the control of pesticides.
