His complete radio silence has raised concerns about the orderly handover of power, while also adding to doubts about how long the blockades could last. However, Normando Corral, president of farm group Famato, said the roadblocks in the top grains-growing state of Mato Grosso could disrupt agricultural shipments if they persist. One of the state's main exports this time of year is Brazil's winter corn crop, which is planted after soybeans are harvested. Evandro Lermen, a member of grain cooperative Coacen in the Brazilian 'soy capital' Sorriso, Mato Grosso, told Reuters corn shipments were not being disrupted by the protests. Rumo, a leading rail company that operates Latin America's biggest grain terminal in Rondonopolis, Mato Grosso, said none of its operations in Brazil had been affected so far.
