Garden Pests and Diseases in Georgia — Identification and Control

A pest or disease rarely appears out of nowhere — there is almost always an early sign that goes unnoticed. Early identification is the difference between a local problem on one shrub and an epidemic across the whole garden.

The most common pests

• Aphids — soft green or black insects on young shoots. They stunt growth and spread viruses. Early control: a strong jet of water, beneficial insects (ladybirds), and insecticidal soap if needed.
• Spider mites — in hot, dry weather. Leaves go waxy and fine webbing appears. Raising humidity slows them.
• Whitefly — common in greenhouses and enclosed spaces.
• Scale insects — brown "shields" on branches, often overlooked.

The most common diseases

• Powdery mildew — white powder on leaves. Poor airflow and shade encourage it.
• Root rot — a result of overwatering and poor drainage. The plant wilts as if short of water when in fact it has too much.
• Scab — on apples and pears, in a wet spring.
• Botrytis (grey mould) — on grapes and fruit, in damp conditions.

The principle of integrated control

A professional doesn't start with chemistry — they start with prevention:

1. Right plant, right place — a healthy plant resists on its own
2. Hygiene — remove diseased leaves, disinfect tools
3. Monitoring — regular inspection for early detection
4. Biological control — beneficial insects
5. Targeted intervention — a chemical only when needed, at the right time

When to call a specialist

Precisely identifying a disease or pest is often hard — a wrong diagnosis means a wrong (and often useless) treatment. Dr. VERDE's seasonal agrotechnical works include disease and pest control based on soil and foliar analyses. For regular monitoring, a yard care subscription catches problems early. In vineyards and orchards, disease control is part of agro project management.
