Identifying Pests & Diseases

A speckle isn’t just a speckle. Symmetric or clustered, with a trail or without - how a symptom spreads often reveals more than what it looks like. This course shows you the diagnostic fork between deficiency, pest, fungus and climate stress, the usual suspects among pests and fungi, and how to prevent problems without reaching for a chemical bottle.

The Fork – Deficiency, Pest, Fungus or Environment?

A symptom tells you THAT something is wrong. Its distribution tells you WHAT.

Identifying Pests – The Usual Suspects

Crime scene before culprit: where a pest sits often already tells you who it is.

Identifying Diseases – When the Climate Invites the Fungus In

A fungus isn’t an attacker, it’s an appointment – the humidity window decides.

Preventing Without a Chemical Cabinet – Hygiene, Quarantine, Climate

The best plant protection is a bouncer system, not a bottle.
