Ganoderma boninense is a fungal pathogen that causes basal stem rot (BSR) disease in oil palm. Being serious problem to the palm industry, monitoring and detecting of utmost importance reduce spread facilitate effective management strategies. Because traditional culture-based assay time-consuming, labour-intensive required special skills mycology, plant pathologists are turning more accurate, s...

nitrogen (n) affects adversely the tobacco yield quantity and quality as it increases yield, chlorine and nicotine contents, but decrease potassium content. this experiment was aimed at optimization of (the balance between) n concentration in leaf, stem and root to increase both yield quantity and quality (high potassium, low chlorine and medium nicotine contents) using artificial neural networ...

Thiabendazole and benomyl were the most effective fungicides for the control of Diplodia natalensis Pole Evans stem-end rot, a major decay of early degreened fruit. This decay was also significantly reduced by imazalil and guazatine, but the level of control was not as consistent as that obtained with thiabendazole or benomyl. Control of Dip lodia stem-end rot was not obtained with DF-1OO or po...
