Conteúdo: |
Four early maturing upland rice genotypes (lAC 165, IAC 25, Guarani and CNA 4136) were assessed for yield response to seed treatment towards rice blast control in three field experiments. Seed treatment with the systemic fungicide pyroquilon (4.0 g a.i./kg seed) suppressed leaf blast in all the three experiments exhibiting different degrees of disease severity. When the cultivars and experiments were examined, it was found that leaf blast was controlled by 26.8%, on average. The mean leaf and panicle blast severities were positively correlated in two out of three experiments. The control of panicle blast varied in different genotypes. Linear multiple regression equations using leaf and panicle blast as the independent variables and grain yield as the dependent variable showed that both leaf and panicle blast significantly accounted for variation in grain yield. Pyroquilon seed treatment significantly increased the average yield in one of the three experiments when compared to the untreated control. |
