THE EFFICACY OF SELECTED SYNTHETIC INSECTICIDES AND BOTANICALS AGAINST FALL ARMYWORM, SPODOPTERA FRUGIPERDA, IN MAIZE

The Efficacy of Selected Synthetic Insecticides and Botanicals against Fall Armyworm, Spodoptera frugiperda, in Maize

Fall armyworm (FAW) was reported for the first time in Africa in 2016.FAW is widely distributed in Ethiopia, causing significant damage to maize.Nine synthetic insecticides belonging to different chemical groups and 11 pesticidal plants (botanicals) were tested for their efficacy against FAW under laboratory, greenhouse, and field conditions.In the

High-precision and high-accuracy stereophotogrammetric image analysis for small to large strain deformation measurement in triaxial apparatus

A deformation measurement system for laboratory soil testing based on stereophotogrammetric canon imageclass mf227dw image analysis was developed with a purpose of characterising soil behaviour continuously from small to large strains.The system is applicable to triaxial tests with pressure chamber and confining fluid by correcting the refraction-i

A Tri-O-Bridged Diels-Alder Adduct from Cortex Mori Radicis

here Sanggenon X, an unusual tri-O-bridged Diels-Alder adduct, was isolated from Cortex Mori Radicis.Its structure was established by spectroscopic analysis, including NMR and HR-MS (High Resolution Mass Spectrometry).Sanggenon X contained three O-bridged rings, where the oxygenated bridgeheads were all quaternary carbons.Chemical methylation was c
