| dc.description.abstract | This study was conducted to evaluate the capability of paclobutrazol (PBZ), sodium silicate (SS), and their combination (PBZ+SS) in inducing resistant response of rice against sheath blight (Rhizoctonia solani Kuhn). In vitro and in vivo tests were conducted through food poisoning method and pot experiment, respectively. Ingression of the fungus was also observed. Results of the experimentation showed that PBZ can slow the growth of the fungus on food poisoning method. However, neither PBZ nor SS had suppressed the growth of the fungus until four days. On the other hand, plants treated with PBZ attained longer incubation period for the appearance of the first symptoms, higher percent protection and lower disease incidence and severity when compared to plants treated with SS. Consequently, all PBZ treated plants had resulted to grains that were abortive. Moreover, ingression of the fungus on PBZ treated plants showed that the formation of infection structures was not observed. However, hyphae observed gained entrance on the stomata of the plant. In general, this study proves the promising capability of PBZ and SS in inducing resistant response of rice against sheath blight. However, due to the formation of abortive grains, mode of application of PBZ should be given importance and further study is recommended to assess the capability of the two test chemicals. | |
