SAO PAULO, BRAZIL — Freezing temperatures this week in Brazil could hurt corn and wheat in the nation’s southern and southeastern states, Reuters reported, citing Conab, the government’s food supply and statistics agency.

There is risk of moderate and severe frosts in Sao Paulo and Parana states, which could affect second corn that is in the grain-filling stage as well as wheat that is in the flowering stage.

Corn and wheat in Mato Grosso do Sul could also be hit by frosts, though in fewer areas, Conab said.

Conab predicts crop failure due to water stress followed by frosts in three states in relation to second corn, Reuters said.

A production drop is also expected for wheat due to drought in Goiás and frosts in Mato Grosso do Sul, São Paulo and western fields in Paraná.
