France: Growers Warn Undelivered Contract Potatoes Will Not Be Paid
Key takeaways
- 12 t/ha on dry Normandy seed plots vs 38-40 t/ha irrigated
- 5 heatwaves above 35°C overwhelmed irrigation equipment
- 0 euros paid for contract potatoes not delivered, says UNPT
- 2027 seed demand in France and the EU is unknown: FN3PT
Why it matters
- For farmers
- Document yield losses and weather events now; check force majeure, size penalty and price revision clauses before final deliveries.
- For processors
- Clarify with growers how shortfalls and undersized tubers will be handled to keep supply relations for 2027.
- For traders
- Seed buyers should wait for virus test results before fixing 2027 seed volumes and classes.
60-second summary
The French potato chain is counting its drought losses, and contract growers look especially exposed. Leaders of the seed federation FN3PT, the growers union UNPT and the fresh potato board CNIPT all agree there are no winners this season. On unirrigated Normandy seed land, yields fell to 12 tonnes per hectare against 38 to 40 tonnes on irrigated plots, and early aphid and leafhopper flights raise virus risk for certification. For ware growers, climatic force majeure may waive volume penalties, but tonnes that are not delivered simply earn nothing, and undersized tubers can be penalised. Only a minority tied loosely to buyers can capture higher spot prices. Starch growers suffer both weak yields and lower prices. The quotes come from one trade weekly, so exact contract outcomes will depend on individual agreements and on how buyers apply them.
The 2026 drought created no winners in the French potato chain, sector leaders say. Seed growers, ware growers, processors and consumers all face losses. The farm weekly Le Betteravier français gathered their views on 23 September.
Seed yields collapse without water
Seed potato growers started the season well, said Bernard Quéré, director of the seed growers federation FN3PT. Then drought and heatwaves cut yields.
In Normandy, non-irrigated seed plots yielded only 12 tonnes per hectare. Irrigated plots on the same farm reached 38 to 40 t/ha.

“It is impossible to know the future demand for seed,” Quéré said. It is also unclear how much area will be planted in France and the EU in spring 2027.
Virus pressure adds a certification risk. Aphids and leafhoppers arrived early. According to Quéré, symptoms of potato virus Y (PVY) are visible, and transmission of leafroll virus (PLRV) is occurring.
Higher seed prices may not reach growers. Many seed contracts were signed in winter 2025–2026. The Egalim law allows price revisions when production costs rise.
Contract growers face a double loss
Ware potatoes will sell more easily this year. However, prices will not fully offset yield losses, the article said.
“Only a minority of producers will benefit from the price situation,” said Alain Dequeker, secretary general of the growers union UNPT. The result depends on how much each grower is tied to processors or collectors by contracts.
Florence Rossillon, director of the fresh potato board CNIPT, cited the rural code. Exceptional climatic events exempt producers from volume penalties. However, contract commitments remain.
Dequeker warned that potatoes not delivered because of low yields will not be paid. This will hit farm profitability hard. Tubers below the required size also risk penalties.
Irrigation reached its limits
Even irrigated growers were disappointed. Their equipment was not designed for five heatwaves above 35°C in one season. Starch potato growers are among the biggest losers, with weak yields and sharply lower prices.
Why it matters
Contracts protect growers against low prices, but not against low yields. This season shows the limits of the model. Contract terms on force majeure, size penalties and price revision are likely to dominate talks for 2027. Seed buyers should also watch virus test results closely.

What next
Growers and buyers will settle deliveries and shortfalls in the coming months. Contract talks for 2027 are expected to focus on climate risk clauses.
