Resumo: | Nowadays, one of the 22 irrigated rice cultivars released by Epagri for Santa Catarina, the SCS121 CL, has an hegemonic predominance in the rice fields of the State. Biologic and strategically, this is of great concern for the State’s rice production because it constitutes a risk for the Clearfield (CL) rice production system. Besides, it means an intense selection pressure even in the phytosanitary area, especially regarding blast. The rapid adoption of SCS121 CL is due to its good yield, unquestionable and easy weed management (also allowing the sow in drained soil), and its tolerance to blast. In this way, it is often used, in situations out of its purpose, which is the control of weedy rice. Data from field experiments and demonstration units indicate that there are cultivars with higher yield than the SCS121 CL and, therefore, they are good options for fields not infested with weedy rice. In this sense, one good option is the brand new cultivar SCS122 Miura. |

Biológica e estrategicamente, isso é preocupante para a orizicultura, pois representa um risco para o sistema Clearfield® (CL), além de significar uma pressão de seleção intensa na área fitossanitária, especialmente quanto à brusone. A rápida adoção do SCS121 CL se deve à sua produtividade, inquestionável facilidade no manejo de plantas daninhas (permitindo também a adoção da semeadura em solo seco), e sua tolerância à brusone. Dessa forma, é usado muitas vezes em situações que fogem à sua finalidade: o controle do arroz daninho. Dados de ensaios de Valor de Cultivo e Uso e dados de Unidades Demonstrativas apontam a existência de cultivares mais produtivos do que o SCS121 CL, portanto bons para áreas não infestadas com arroz daninho, entre eles o novo cultivar SCS122 Miura.
