Erythritol-Based Tephritid Fruit Fly Bait via Dry Blending
Rejected
This concept did not clear the framework. The reasoning is published in full below.
What the assessment found
| Incumbent benchmark | GF-120 NF Naturalyte Fruit Fly Bait |
| Entry application | small-to-medium-sized organic fruit orchards |
| Measured advantage | conceded failure; 3 to 5 days to 100% mortality vs <24 hours for GF-120 |
| Time to first revenue | 24 months |
| Gross margin at parity | 90.2% |
| Startup CapEx | $35,000 |
| Payback from first sale | 0.1 months |
| Capital productivity | 906.1x |
| Regulatory risk | Moderate — qualification costs reported ($250,000 estimated) |
| Protectability | Not declared — no specific protectable contribution beyond the published baseline |
Why it failed
- Voided by: Mismatched comparison, Capital and time to revenue, Negative control / sub-2x, Form-factor / handling regression, Absence search missing, No defensible contribution declared
- Evidence rests on non-peer-reviewed sources
- Absence asserted, search unreported
- No protectable contribution declared
Assessment
The proposed venture explicitly concedes failure on primary efficacy, taking 3-5 days to reach 100% mortality compared to <24 hours for the incumbent. Regulatory approval under EPA FIFRA requires 24 months, failing the velocity gate, while missing a structured market absence ledger and defensibility breakdown.
Also flagged
- Price parity asserted, not sourced
- no_production_runsheet
A rejection is not a claim that the science is wrong. It means the venture case did not survive: the comparator was not what the buyer actually buys, the comparison was not like-for-like, the advantage fell short of a step change, or the capital and time to first revenue were prohibitive.
