Course map
Every lesson opens with objectives and a diagram, carries sourced numbers, ends with a farm task and three questions.
- 01Observation & PatternMost crop losses are named wrongly on the first day, and the wrong name leads to the wrong action. Describing what you see before deciding what it is costs nothing.
- 02Differential DiagnosisThe same brown spot can be a bacterium, a mite, or water that sat on the cap too long. Three causes, three different actions, and only one costs nothing.
- 03Evidence & Negative EvidenceA measurement is worth taking only if its answer would change what you do next. Many growers collect numbers that change nothing and skip the one that would have saved the crop.
- 04Biosecurity & Chemical CautionAlmost every serious mushroom disease arrives on something that came through the door: casing, spawn, shoes, flies or air. Controlling the door costs less than any cure.
