Common Alpine Storks Bill Flower Diseases: How to Identify and Treat Them

Post date |

Pests and diseases are common problems when growing flowers and ornamentals. They can cause both direct and indirect damage that can be costly. Use Penn State Extension’s extensive resources to find out more about managing flower pests and diseases, including Fletcher scale, leafhoppers, spotted lanternfly, webworms, mites, caterpillars, pillbugs, weevils, scales, borers, beetles, aphids, moths, blight, necrosis, root rot, and freeze damage.

The Alpine Storks Bill, known scientifically as Erodium reichardii, is a delightful flowering plant that thrives in rock gardens and alpine environments. However, like any plant it can fall victim to diseases that impact its health and appearance. This article will overview the most prevalent diseases affecting Alpine Storks Bill flowers providing tips on identification and effective treatment methods.

Powdery Mildew

Powdery mildew is a fungal disease that commonly impacts Alpine Storks Bill flowers.

Identification

  • White powdery coating on leaves, stems, and flowers
  • Distorted growth and yellowing of foliage
  • Stunted plants

Treatment

  • Improve air circulation around plants
  • Remove and destroy infected plant parts
  • Apply fungicides containing myclobutanil, propiconazole, or triforine

Botrytis Blight

Also called gray mold, this fungal infection can ruin Alpine Storks Bill blooms

Identification

  • Gray fuzzy mold on flowers, leaves, stems
  • Water-soaked lesions on plant parts
  • Wilting or dying flowers

Treatment

  • Remove and dispose of infected plant material
  • Space plants properly to encourage airflow
  • Apply fungicide sprays containing chlorothalonil or neem oil

Leaf Spot

Fungal or bacterial leaf spots can disfigure Alpine Storks Bill foliage.

Identification

  • Small, dark spots on leaves
  • Spots enlarge and merge over time
  • Leaves yellow and drop prematurely

Treatment

  • Prune and destroy infected leaves
  • Use drip irrigation to keep foliage dry
  • Apply copper-based fungicide sprays as a preventative

Root Rot

Excess moisture can cause root rot in Alpine Storks Bills.

Identification

  • Wilting, yellowing leaves
  • Stunted growth
  • Brown, mushy roots

Treatment

  • Improve drainage in overly wet soils
  • Replant in well-draining soil mix
  • Apply fungicide drench to control infection

Aphid Infestation

These tiny sap-sucking insects can swarm Alpine Storks Bill plants.

Identification

  • Clusters of green, yellow, black soft-bodied insects on leaves and stems
  • Curled, distorted leaves and stunted growth
  • Sticky residue on foliage

Treatment

  • Knock aphids off plant with strong water spray
  • Apply insecticidal soap or neem oil sprays
  • Release ladybugs and other beneficial insects to feed on aphids

With prompt identification and treatment, most Alpine Storks Bill diseases and pests can be successfully managed. Consistent monitoring, prevention, and organic treatments are key to protecting these delicate blooms. A bit of diligence will keep your Alpine Storks Bill flowers thriving for years of beauty and enjoyment.

Common Flower and Ornamental Diseases

Being able to accurately diagnose pests and diseases is crucial if you want to control them and get the best results from your flowers. Learn how to recognize and distinguish between symptoms and signs of stress, including damage and diseases, and you’ll be able to employ best management practices.

Use Penn State Extensions resources to help identify diseases that affect some of the most popular plants. Here are some examples:

  • Roses: Blackspot, anthracnose, cankers, and downy mildew
  • Pansies: Cercospora leaf spot, fusarium wilt, scab, and pythium root rot
  • Echinacea: Alternaria leaf spot, aster yellows, foliar nematode, and white smut
  • Narcissus: Basal rot, lesion nematode, scorch, stem and bulb nematodes
  • Tulips: Fire, viruses, root rot, stem and bulb nematode
  • Begonia: Bacterial leaf spot and blight, botrytis blight, foliar nematode, and powdery mildew
  • Chrysanthemums: Ascochyta ray blight, bacterial blight, bacterial leaf spot, and chlorotic mottle
  • Poinsettia: Ammonium toxicity, bacterial canker, bacterial stem rot, and botrytis stem canker
  • Azalea and rhododendron: Botryosphaeria canker, botrytis blight, cylindrocladium blight, leaf, and flower gall
  • Hostas: Anthracnose, petiole rot, bacterial soft rot, and hosta virus
  • Boxwood: Decline, blight, leaf burn, and leaf spot
  • Juniper: Cedar-apple rust, cercospora blight, twig blight, and Japanese apple rust
  • Palms: Cold injury, fluoride injury, helminthosporium leaf spot, and leaf burn

Biocontrols and Pesticide Application in Floriculture

There are several ways to control pests and diseases. Traditionally, pesticides have been used to control pests in floriculture. We still use them today, not quite as much, but especially when pest populations have rapidly expanded or were detected late and need to be quickly brought under control. The four most common types of pesticides are synthetic, natural, organic, or chemical.

An increasing number of homeowners and green industry professionals are using Integrated Pest Management to manage pests. IPM is an ecosystem-based strategy that focuses on long-term prevention of pests or their damage employing a combination of techniques such as the use of resistant varieties, habitat manipulation, modification of cultural practices, and biological control.

Biological controls include beneficial insects such as ladybird beetles, green lacewings, and aphidoletes. Biopesticides are also used; these are pesticides that are derived from natural materials such as animals, plants, bacteria, fungi, and certain minerals.

FAQ

How do you control Storksbill?

Control Tips Winter annual stork’s bill plants compete and set seed early in the spring and should be controlled the previous fall with tillage after the majority of plants have germinated. Stork’s bill should be treated as early as possible with herbicides.

Can decorative flowers carry diseases?

Decorative flowers coming from an international origin on a flight can potentially carry pests and disease, just like other imported plants and animals can. However, regulations and safety measures are usually in place to mitigate these risks.

How do you identify Erodium?

Erodium has red pigments naturally, so stress tends to bring out red coloration in this genus. Flowers come in shades of bright pink to purple. Petals are ovate and often have dark spots on the bases. The flowers are arranged in a loose cluster and have ten filaments (only five of which are fertile) and five styles.

What is another name for storksbill plant?

Erodium cicutarium, also known as common stork’s-bill, redstem filaree, redstem stork’s bill or pinweed, is a herbaceous annual – or in warm climates, biennial – member of the family Geraniaceae of flowering plants.
