| Popis: | Anthracnose caused by Colletotrichum lindemuthianum is one of the main diseases that affect the bean crop. The use of semisynthetic compounds for controlling anthracnose aims at providing a higher balance to the ecosystem and a lower environmental impact. Based on this context, the objective of this work was: a) to carry out the prospection of compounds such as Phenyl S Citral, Phenyl Se Citronellal, and Citral at concentrations of 1, 0.5, 0.25, 0.125, 0.0625, 0.0312, 0.0156, 0.0078, and 0.0039%, which were modified from the essential oil of citronella and lemongrass, for controlling C. lindemuthianum; b) to evaluate the initial performance of seedlings and treat the incidence of C. lindemuthianum in bean seeds with Phenyl S Citral and Phenyl Se Citronellal at concentrations of 0.125 and 0.0625%. Phenyl Se Citronellal at 0.5% controlled 100% of mycelial growth and Phenyl S Citral at 0.5 and 1% controlled more than 50% of mycelial growth of C. lindemuthianum. The treatment with Phenyl S Citral and Phenyl Se Citronellal did not affect the physiological quality of bean seeds while increasing seedling development when using the 0.0625% concentration of Phenyl Se Citronellal. Treatment with Phenyl Se Citronellal at both concentrations decreased the incidence of C. lindemuthianum infection. |
