Chrysanthemum Plant Health Overview in South Carolina
Chrysanthemums, or hardy garden mums, like full sun and fertile, well-drained soil. They need regular watering because their roots are very shallow. These hardy garden mums were recently transferred into the genus Dendranthema, which is now a separate genus from the marginally hardy florist mums. Although the list of diseases that may attack chrysanthemums is long, mums are relatively trouble-free. However, drought will cause woody, stunted growth, and overwatering will cause yellowing leaves that blacken and drop.
Chrysanthemum Diseases: Leaf Spot on Chrysanthemum in South Carolina
Leaf spot is a common fungal disease that affects chrysanthemum foliage and may cause premature leaf drop.
Cause
Several fungal pathogens cause leaf spot on chrysanthemum, including:
- Alternaria species
- Cercospora chrysanthemi
- Septoria chrysanthemella
- Septoria chrysanthemi
These fungi overwinter as spores in infected plant debris in the garden.
Symptoms
Symptoms consist of spots on the leaves.
- Spots begin yellowish
- Spots enlarge to dark brown or black
- Spots range from ⅛ to 1 inch or more in diameter
- A purple margin may surround spots
- Leaves may wither prematurely as the disease progresses
- Lower leaves are typically infected first
Prevention & Treatment
Cultural Controls
- Handpick and destroy the infected leaves.
- Regularly clean up and destroy dead plant debris to reduce spore populations.
- Apply a layer of mulch to reduce splashing of spores from the soil onto foliage.
When disease severity warrants chemical control, effective fungicides contain the following active ingredients, including:
- Chlorothalonil
- Mancozeb
- Myclobutanil
- Propiconazole
- Thiophanate-methyl
See Table 1 for examples of brands and products. Follow all the directions on the label for mixing rates, use, reapplication intervals, and safety.
Chrysanthemum Diseases: Foliar Nematodes on Chrysanthemum
Foliar nematodes are microscopic roundworms that infect chrysanthemum leaves and cause browning and premature leaf death.
Cause
Foliar nematodes (Aphelenchoides ritzema-bosi) are slender, unsegmented roundworms that are barely visible to the unaided eye.
- Overwinter in the soil and infested plant material
- Survive in fallen leaves for more than one year (dormant)
- Hardy chrysanthemums that develop yellow-brown spots starting on the lower leaves
- Move in films of water on plant surfaces created by spring rains and overhead irrigation
- Enter leaves through the stomata
They additionally infest hosta and ferns.
Symptoms
Hardy chrysanthemums that develop yellow-brown spots beginning on the lower leaves and gradually moving upward on the stems may be infested with foliar nematodes.
- Yellow-brown leaf spots begin on lower foliage
- Spots gradually move upward on the plant
- Spots enlarge and merge
- Entire leaves become brown and brittle
- Leaves die and fall prematurely
- Severe infestations can kill entire plants
Foliar nematode injury is often confused with fungal leaf spot damage; however, fungal leaf spots are typically black, rather than brown.
Prevention & Treatment
Cultural Controls
- Apply mulch in the spring to reduce nematode movement from the soil onto foliage.
- Avoid overhead irrigation that wets leaves.
- Use drip irrigation to reduce leaf wetness and foliar nematode spread.
- Remove, bag, and dispose of infected plant material and surrounding surface soil.
Chemical Control
Foliar sprays with insecticidal soap may help reduce nematode populations.
- Spray insecticidal soap immediately after removing infected plants.
- Thoroughly spray nearby plants to control nematodes present on foliage but not yet inside leaves.
See Table 1 for examples of brands and products.
Chrysanthemum Diseases: Rust on Chrysanthemum
Rust is a fungal disease of chrysanthemum that causes characteristic pustules on leaf undersides and may reduce plant vigor and flowering.
Cause
Rust diseases of chrysanthemum are caused by the fungal pathogens in the genus Puccinia:
- Puccinia chrysanthemi (brown rust)
- Puccinia horiana (white rust)
These fungi infect leaf tissue and produce powdery orange pustules on leaf undersides.
Symptoms
Brown Rust (Puccinia chrysanthemi)
- Pale areas develop on upper leaf surfaces
- Powdery orange pustules form on the undersides of leaves
- Severely infected plants are weakened
- Flower production may be reduced
White Rust (Puccinia horiana)
- Yellow spots develop on the upper leaf surfaces
- Tan pustules form on the lower leaf surfaces
- Pustules later turn white as spores are produced
Prevention & Treatment
Cultural Controls
- Remove infected leaves as soon as symptoms appear.
- Space plants farther apart to improve air circulation.
- Provide good ventilation around plants.
- Water the soil without wetting foliage.
Resistant Varieties
The following chrysanthemum varieties have shown resistance to rust:
- ‘Achievement’
- ‘Copper Bowl’
- ‘Escapade’
- ‘Helen Castle’
- ‘Mandalay’
- ‘Matador’
- ‘Miss Atlanta’
- ‘Orange Bowl’
- ‘Powder Puff’
Chemical Control
If the disease is severe enough to require fungicides, products containing the following active ingredients may be used:
- Chlorothalonil
- Mancozeb
- Myclobutanil
See Table 1 for examples of brands and products. Follow all directions on the label.
Chrysanthemum Diseases: Wilt on Chrysanthemum
Wilt diseases are soil-borne fungal infections that disrupt water movement in chrysanthemum, causing yellowing, decline, and plant death.
Cause
Wilt of chrysanthemum is caused by soil-borne fungal pathogens:
- Verticillium albo-atrum
- Fusarium oxysporum f.sp. chrysanthemi
These fungi enter the plant through the roots and invade the vascular system, restricting water movement within the stem.
Symptoms
- Leaves are yellow and brown, beginning near the base of the plant
- Leaves die progressively up the stem
- Plants become stunted
- Flower production is reduced or absent
- Entire plant may wilt and die
Prevention & Treatment
Cultural Controls
- Remove and destroy all infected plant material.
- Practice strict sanitation to prevent the spread in planting areas.
- Avoid planting chrysanthemums in previously infested soil.
Resistant Varieties
Use resistant chrysanthemum varieties when available.
Soil Management
If Fusarium has been a problem:
- Increase soil pH to between 6.5 and 7.0.
Chemical Control
Chemical control is generally not effective once plants are infected. Prevention through sanitation and the use of disease-free plants is critical.
Purchase certified disease-free plants when possible.
Chrysanthemum Diseases: Powdery Mildew on Chrysanthemum
Powdery mildew is a common fungal disease of chrysanthemum that produces a distinctive white powdery coating on leaves.
Cause
Powdery mildew on chrysanthemum is caused by the fungus:

Chrysanthemum Insect Pests: Aphids on Chrysanthemum in South Carolina
Aphids are common sap-feeding insect pests of chrysanthemum that cause distorted growth and may transmit plant viruses.
Cause
Chrysanthemum aphids (Macrosiphoniella sanborni) and other aphid species feed on chrysanthemums.
Aphids are brown to black. However, other aphid species that may feed on chrysanthemums range from green to pink.
Aphids feed by piercing plant tissue and extracting plant sap.
Common feeding sites include:
- New shoots
- Undersides of leaves
- Flower buds
- Developing flowers
Aphids excrete honeydew (a sugary substance) as they feed, which promotes the growth of sooty mold.
Aphids may also transmit plant viruses.
Aphid populations increase rapidly due to their high reproductive rate.
Symptoms
- Distorted or curled new growth
- Stunted plant growth
- Sticky honeydew on plant surfaces
- Black sooty mold growing on honeydew
- Reduced plant vigor
- Potential transmission of viral diseases
- Heavy infestations may cause plant decline or death
Prevention & Treatment
Cultural Controls
- Spray plants with a strong stream of water to dislodge aphids
- Direct spray especially to the undersides of leaves.
- Repeat water sprays every 2 days as needed
- Apply at least 3 treatments for effective suppression.
Biological Control
Encourage naturally occurring aphid predators whenever possible.
Beneficial insects help maintain aphid populations below damaging levels.
Avoid unnecessary insecticide use that may harm beneficial insects.
Chemical Control
If natural predators do not keep aphids under control and serious damage is occurring, insecticides may be used.
Active ingredients include:
Naturally occurring active ingredients
- Insecticidal soap
- Horticultural oil
Synthetic active ingredients
- Acephate
- Bifenthrin
- Cyfluthrin
- Malathion
- Permethrin
See Table 1 for examples of brands and products. Follow all label directions and precautions.
For more information, see HGIC 2009, Integrated Pest Management (I.P.M.) for Aphids.
Chrysanthemum Insect Pests: Spider Mites on Chrysanthemum
Spider mites are tiny plant-feeding arachnids that cause stippling, discoloration, and webbing on chrysanthemum foliage, especially during hot, dry conditions.
Cause
Two-spotted spider mites (Tetranychus urticae) and other mite species commonly infest chrysanthemums.
Spider mites are not insects but are more closely related to spiders.
Key characteristics:
- Extremely small and difficult to see without a magnifying lens
- Piercing mouthparts with which they puncture plant tissue to remove plant sap
- Populations increase rapidly during hot, dry weather
- Infestations usually begin on lower leaf surfaces
Symptoms
- Tiny yellow stippling (small spots) on leaves
- Leaves appear dusty or speckled
- Distorted foliage as damage progresses
- Discolored or withered flowers
- Fine webbing on flower buds, between stems, and on the undersides of leaves
- Damage is often first noticed on lower leaf surfaces
Early infestations are often overlooked until the damage becomes more severe.
Prevention & Treatment
Cultural Controls:
- Spray plants forcefully with water to remove mites.
- Repeat water sprays as needed.
- Apply at least 3 treatments for effective suppression.
- Remove and destroy severely infested plant parts when populations are high
Chemical Control
Insecticidal soap may provide effective control when applied early in the infestation.
Miticides labeled for spider mite control include:
- Tau-fluvalinate
- Bifenthrin
Two or more applications at 5- to 7-day intervals are usually required.
Apply sprays thoroughly to all leaf surfaces.
See Table 1 for examples of labeled products. Follow all label directions.
Chrysanthemum Insect Pests: Leafminers on Chrysanthemum
Leafminers are larval flies that tunnel within chrysanthemum leaves, producing visible winding trails and reducing plant vigor.
Cause
Chrysanthemum leafminer (Chromatomyia syngenesiae) is the larval stage of a small dark-colored fly approximately ⅛-inch.
Adult females lay eggs on the undersurfaces of leaves.
After hatching, larvae:
- Enter leaf tissue
- Feed between the upper and lower leaf surfaces
- Create visible tunnels (mines) as they feed
Larvae live and develop inside leaf tissue until maturity.
Symptoms
- Winding pale green to brown trails within leaves
- Visible black specks (larval waste) inside tunnels
- Leaves may dry up and droop downward
- Heavily infested leaves may decline prematurely
- Overall plant vigor may be reduced with severe infestations
Prevention & Treatment
Cultural Controls
- Prune and destroy infested leaves promptly.
- Collect and dispose of fallen leaves to reduce overwintering populations.
- Remove plant debris at the end of the growing season (fall).
Chemical Control
If damage is severe, foliar systemic insecticides may be used.
Active ingredients include:
- Acephate
- Spinosad
