Abstract
Optical spectroscopy has been in full expansion for several years for sustainable development which is a challenge impacting the agricultural sectors Furthermore the phytopathological approach by multimodal spectroscopy is an actuality method allowing particular to detect pathogenic diseases in real-time to monitor their development early and consider preventing their spread The aim of this research is the study of effects caused by weeds according to the phenomenon of photosynthesis influencing the yield of fields of rice and vegetable crops The multispectral transmission reflection and scattering microscope has been used for image acquisition in the ultra-violet to the near-infrared band Through the microscopic images obtained the average intensities of the pixels of an area of the image have been evaluated to reconstruct their corresponding spectrum to proceed with a study of their wavelength-by-wavelength optical property The results obtained by the adopted multimodal technique highlighted the influence of weeds on rice and vegetable plants in the ultraviolet visible and near-infrared range in Yamoussoukro in C te d Ivoire also estimating their chlorophyll level at specifique wavelengths The development of spectroscopic and multimodal analysis methods has mainly contributed to the diagnosis of certain weeds which are among others Boerhaviadiffusa Echinochloastagnina Mimosa pigra L Euphorbia heterophylla Perotisindica Lepto-chloacarulescens Imperata cylindrical and Cassia Mimosoideae
