Apricots bloom early and can be sensitive to spring weather, wet-season diseases, bark injury and regional insect pests. Begin with the affected plant part and symptom pattern; frost, irrigation stress and disease can produce similar dieback.
Apricot symptom guide
- Brown flowers, twig dieback or rotting fruit: investigate brown rot, but compare symptoms with frost injury.
- Small leaf holes with colored margins: consider shot hole disease or insect feeding.
- Sunken bark, gum and branch dieback: bacterial canker, borers, mechanical injury and other stresses are possible.
- Wilting with wet soil or root discoloration: investigate drainage and root or crown disease.
- Curled shoots and honeydew: inspect for aphids.
- Fixed bumps on twigs or leaves: inspect for scale insects.
- Stippling or bronzing: inspect leaf undersides for mites.
- Larvae in shoots or fruit: identify peach twig borer, oriental fruit moth or another local species using trap and Extension guidance.
Brown rot
Brown rot can infect blossoms, shoots and fruit. Remove mummified fruit and diseased material where locally recommended, reduce fruit wounds and unnecessary wetting, and maintain an open but sun-safe canopy. Preventive fungicide programs depend on bloom stage, weather, regional resistance concerns and the current label.
Shot hole disease
Shot hole begins as small lesions on leaves and may also affect buds, twigs and fruit. Because insects can make similar holes, inspect the margins and surrounding tissue. Regional programs may emphasize sanitation and preventive applications during specific dormant or wet-weather periods.
Bacterial canker and gumming
Gum is a stress response, not a diagnosis. Examine the bark beneath and around it, note whether a canker is enlarging, and check for borer frass or physical wounds. Avoid unnecessary trunk injury, poor drainage and incorrect pruning timing. Seek local diagnosis before cutting major limbs.
Root and crown problems
Apricots require drainage appropriate to the rootstock and soil. Chronic saturation can produce yellowing, weak growth and decline. Check planting depth, irrigation distribution and the root flare before applying fertilizer or a pesticide.
Insect and mite management
Use a hand lens, traps or local phenology guidance to identify the pest and susceptible life stage. Protect beneficial insects and avoid routine broad-spectrum treatment. Dormant oils, microbial products and other controls are not interchangeable; use one only when the label lists apricot and the target pest.
An integrated prevention plan
- Choose a site with suitable chill, bloom risk and drainage.
- Use current product pages for offered variety and rootstock characteristics.
- Protect trunks and scaffold limbs from sunburn and mechanical injury.
- Irrigate according to soil moisture and weather.
- Remove confirmed disease reservoirs and damaged fruit as recommended locally.
- Record bloom, weather, traps and symptoms to improve timing.
- Follow every pesticide label for crop, target, rate, timing, PPE, re-entry, harvest and mixture directions.

Identify the pest or problem first. For pesticides, repellents, traps, and biological controls, confirm that the current label or directions cover the target site and pest. Follow all directions and precautions.
