The dynamics of the collision on BR-163 and the immediate consequences
The Mato Grosso do Sul Civil Police is investigating the accident, which occurred between kilometers 568 and 569 of BR-163, at around 3:10 pm. The first information indicates that one of the vehicles entered the opposite lane, colliding with a trailer.

Sergio Doná’s legacy of scientific contributions
Sergio Doná was an agronomist and had a master’s degree in Tropical and Subtropical Agriculture. His career was dedicated to public research and agricultural development in the Médio Paranapanema region, in the interior of São Paulo.
- At APTA Regional de Assis, a unit that he headed, Doná developed and participated in several researches on important cultures for the region, such as:
- Cassava
- Fruit growing
- Soy
- Corn
- Sugar cane
He also worked on the regional evaluation of materials created by the Campinas Agronomic Institute (IAC) breeding program and actively participated in the transfer of these technologies to farmers. In fruit growing, he stood out for studies with the ‘Niágara Rosada’ vine, investigating rootstocks, productivity, production times, irrigation and control of diseases and pests. Their work focused on expanding production and income alternatives, especially benefiting small and medium-sized producers, in addition to monitoring fruit flies.
