The article reports an unusual demand for onions in the Ituporanga region of SC, Brazil, leading to high prices and the advancement of harvest by some producers. The average price for onions has hit a record high of R$ 5.75/kg since 2000 due to low supply and high demand. However, 'flowered' onions, affected by unusual cold, are sold at a lower price of R$ 2.50/kg. There are concerns about the potential impact of this cold on future onion harvests, especially medium and long cycle cultivars, but the impact on the national supply is expected to be minimal, contributing to the high prices.
