InsectCroton (Codiaeum variegatum)

Scale insects and mealybugs on Croton

Sticky leaves, sooty mold and decline

What to look for
Brown or pale attached scales, white cottony insects in leaf axils, sticky honeydew, black sooty growth and gradual yellowing or leaf drop.
How to confirm
Inspect stems, petioles, new growth and both leaf surfaces with magnification. Confirm live insects beneath covers before treating; sooty mold alone is secondary evidence.
Responsible remedy
For light infestations, isolate container plants, prune badly infested tissue and wash or hand-remove insects. Low-impact options include a thorough application of insecticidal soap or horticultural oil labeled for ornamental Croton; repeat only at the label interval and test a small area first. For persistent infestations, a licensed professional may select a labeled systemic or contact product while protecting pollinators and beneficial insects.

MiteCroton (Codiaeum variegatum)

Spider mites on Croton

Stippled, bronzed or webbed foliage

What to look for
Fine pale stippling progresses to bronzing, curling and leaf drop; fine webbing may appear between leaves and stems during heavier infestations.
How to confirm
Tap suspect foliage over white paper and look for moving specks with magnification. Separate mite injury from thrips, nutrient stress and sun scorch.
Responsible remedy
Rinse foliage, correct drought stress and avoid unnecessary broad-spectrum insecticides that remove predators. Use labeled insecticidal soap or horticultural oil for confirmed light infestations with complete underside coverage. Severe cases may require a miticide specifically labeled for the site; rotate modes of action rather than repeating one product.

InsectCroton (Codiaeum variegatum)

Thrips on Croton

Scarred or distorted new foliage

What to look for
New leaves may emerge distorted or streaked with silvery scars and tiny dark fecal specks; flowers and tightly folded growth can shelter the insects.
How to confirm
Tap new growth over white paper, inspect with magnification and use sticky cards as a monitoring aid. Confirm the pest because mites and exposure injury can look similar.
Responsible remedy
Remove heavily damaged tips, reduce weed hosts and preserve predators. A labeled insecticidal soap can suppress exposed insects; spinosad may be considered only where the exact ornamental and site label permits it. Repeat monitoring because eggs inside plant tissue escape many contact treatments.

Disease / culturalCroton (Codiaeum variegatum)

Croton root rot and water stress

Wilt, yellowing and leaf drop

What to look for
Plants wilt despite wet soil, yellow, drop leaves or develop dark soft roots and lower-stem decline. Drought stress can also wilt and drop foliage but occurs with a dry root ball.
How to confirm
Check moisture through the full root zone, drainage, planting depth and root condition before assuming a pathogen. Submit a sample when decline continues after correcting water management.
Responsible remedy
Stop automatic daily watering, restore drainage and allow oxygen back into the root zone. Remove irreversibly decayed roots or plants and sanitize reused containers. No household tonic reverses dead roots; a labeled fungicide is justified only after the disease and site are confirmed.

No pesticide is the first response; correct drainage and irrigation

Active ingredient: Cultural correction first; label and diagnosis determine any fungicide
InsectSt. Augustinegrass

Southern chinch bug

Brown or expanding patches

What to look for
Irregular yellow-to-brown patches that often expand along hot pavement edges.
How to confirm
Use flotation tests at several points along the boundary between healthy and damaged turf.
Responsible remedy
Correct irrigation and thatch problems; preserve predators; spot-treat only confirmed active areas and rotate insecticide modes of action.

White grubs

Root loss and loose turf

What to look for
Wilted or brown turf may lift easily because larvae have consumed roots.
How to confirm
Cut and fold back a measured turf section; identify and count active larvae before treating.
Responsible remedy
Treat damaging populations at the susceptible young-larval stage. A labeled soil-targeted product generally must be watered in exactly as directed.

Tropical sod webworm

Chewed blades and thinning turf

What to look for
Notched blades, green-brown pellets and rapidly thinning patches; moths may rise when turf is disturbed.
How to confirm
Use a soap flush over a small measured area and inspect at dusk for larvae and fresh feeding.
Responsible remedy
Preserve natural enemies and treat young confirmed larvae when damage warrants it. Coverage and timing matter.

Mole crickets

Tunneling and uprooted turf

What to look for
Raised tunnels, loose soil and thinning turf where roots are disturbed or eaten.
How to confirm
Apply a soap flush to a measured area and inspect tunnels; distinguish active insects from old damage.
Responsible remedy
Target small nymphs when monitoring confirms activity. Follow the selected lawn label and watering directions.

DiseaseSt. Augustinegrass

Gray leaf spot

Spotted blades and scorched appearance

What to look for
Oblong tan-to-gray lesions with dark margins; severe infection can give turf a scorched cast.
How to confirm
Inspect individual blades and rule out drought, insects and chemical injury; laboratory diagnosis may be appropriate.
Responsible remedy
Reduce prolonged leaf wetness, irrigate early, avoid excess nitrogen and improve mowing practices. Use fungicide only when diagnosis and label support it.

Large patch / brown patch

Circular or expanding patches

What to look for
Expanding rings or patches, often during prolonged wet conditions; affected leaves may detach near the base.
How to confirm
Evaluate weather, pattern and leaf bases; distinguish from take-all root rot and irrigation problems.
Responsible remedy
Limit leaf wetness, correct overwatering and avoid unnecessary nitrogen. Preventive or early-curative fungicides must match the turf, disease and timing on the label.

Take-all root rot

Weak roots and irregular decline

What to look for
Irregular yellowing and thinning with dark, shortened or decayed roots.
How to confirm
Examine roots and stolons; submit a representative sample when symptoms overlap other problems.
Responsible remedy
Correct drainage, irrigation, pH and cultural stress. Professional diagnosis is strongly recommended before a fungicide program.

Irrigation coverage failure

Dry arcs or straight-edged decline

What to look for
Damage follows head spacing, straight lines or obstructions rather than biological spread.
How to confirm
Run each zone manually and compare catch-can output and soil moisture in healthy and affected areas.
Responsible remedy
Repair or realign heads, correct pressure and scheduling, and avoid adding unnecessary pesticide or fungicide.

Product names are examples—not prescriptions.

Registrations, formulations and labels change. Confirm the exact product is registered for your site, turf species and target pest. Read and follow the entire current label; the label is the law. Never use a product because the brand name appears here if your container label does not list the use.

Restricted-use products and treatments requiring specialized licensing should be handled by an appropriately licensed professional.
