## Corrections Applied

### Proper Nouns — Speaker Names
- "Dr. Chris Mahabou" → "Dr. Chris Marble" (Block 2, line 7)
- "Dr. Mahabou" → "Dr. Marble" (Block 3, line 11)

### Institutions and Programs
- "Mid-Florida Church and Education Center" → "Mid-Florida Research and Education Center" (Block 5, line 19)
- "weenhouses" → "greenhouses" (Block 7, line 27)

### Systematic Whisper Error — "herbicides" Rendered as Various Garbles
This was the most pervasive error in the transcript. Whisper consistently failed to capture "herbicides" and rendered it as "cervicides," "service sites," "surface sites," "service side," "service size," "services," and "pelvies sites." All corrected to "herbicides" in context:

- "pelvies sites" → "herbicides" (Block 8, line 31)
- "pre-emergent surface sites" → "pre-emergent herbicides" (Block 92, line 367)

- "post-emergent cervicides" → "post-emergence herbicides" (Block 338, line 1351)
- "pre-emergent cervicides" → "pre-emergent herbicides" (Block 340, line 1359)
- "pre-emergent service sites" → "pre-emergent herbicides" (Block 348, line 1391)
- "pre-emergence services" → "pre-emergence herbicides" (Block 388, line 1551)
- "pre-emergent service size" → "pre-emergent herbicides" (Block 390, line 1559)
- "pre-emergent surface sites" → "pre-emergent herbicides" (Block 394, line 1575)
- "pre-emergent surface site" → "pre-emergent herbicide" (Block 396, line 1583)

### Systematic Whisper Error — "weed species/spectrum" Rendered as "wheat"
- "wheat species" → "weed species" (Blocks 42, 192, 424, 501)
