Extracción y formulación de un bioinsecticida a partir de amida isobutílica 4,5-dihydro-piperlonguminina extraída del pipilongo (Piper tuberculatum) para el control del pulgón amarillo (Sipha flava) en caña de azúcar (Sacharum officinarum)
In this study we determined –by using the spectrophotometric method proposed by Hans-mann and an analysis of variance with Fisher-distribution– the phytotoxicity of the carrier or fixer of butyl amide, polivinyl pyrrolidone (PVP), with 15 two-month old sugar cane seedlings of range PR 61-632, with a...

In this study we determined –by using the spectrophotometric method proposed by Hans-mann and an analysis of variance with Fisher-distribution– the phytotoxicity of the carrier or fixer of butyl amide, polivinyl pyrrolidone (PVP), with 15 two-month old sugar cane seedlings of range PR 61-632, with a concentration of 4,000 ppm. The polyvinylpyrrolidone (PVP) showed no morphological alterations in the seedling to this value and therefore could be used as a carrier of the 4,5-dihydro-piperlonguminina. For the analysis of the results we applied the statistical method of Henderson-Tilton, from which the insecticide effect of the 4,5-dihydro-piperlonguminina was tested and those solutions that showed mortalities above 97% were classified as the best formulations. |
