Weed Hosts

The cocoa tree, the mainexport crop in Côte d'Ivoire is frequently attacked by a disease: brown pod rot, caused by Phytophthora spp. which causes a considerable drop in production. This soil-borne pathogen attacks on so-called weeds when environmental conditions are favourable. The presence of these susceptible weed hosts can amplify this scourge of brown rot by transmitting the pathogen to the crop plant. In order to improve the yield of this crop, a study was conducted in the Nawa region to identify the weed hosts through the characterization of the pathogen. This study consisted first in the inventory of susceptible host weeds of Phytophthora spp. and second in the morphological characterization of the pathogen. Concerning the host weeds inventory we procceeded determining all symptomatic weeds located within 3 m of the cocoa plants affected by brown rot. We identified 48 susceptible host species, divided into 41 genera and 22 families and we observed brown spots on the leaves of Oplismenus burmannii and Laportea aestuans; on the leaves of Clerodendrum splendens and Xanthosoma mafaffa, brown necroses surrounded by a yellow halo were noticed. Oily brown spots were examined on the leaves of Ageratum conyzoides. On the proximal, lateral and distal parts of the pods symptoms of brown spots covered with whitish mycelia were observed. Phytophthora strains obtained from the pods and weeds on PDA culture medium were characterized by matted, white mycelial colonies with a cottony appearance. Microscopic features revealed the presence of sporocysts, oospores and chlamydospores of different shapes.

Anyama is located on the onshore of the sedimentary basin of Côte d’Ivoire. It is to the east of the basin and the formations, particularly those dating back to the Quaternary may have been studied. Based on samples, collected from two drill holes (An1 and An2), each 114 m deep, a sedimentology and mineralogy characterization of Plio-Quaternary formations was carried out. The sedimentological study was assessed by taking account the lithology, the grain size, the transport model and the environment deposit of the sediments, the morphoscopy and the exoscopy of the quartz grain. The mineralogy study was made on clays through X-Ray Diffraction (XRD). Lithological characterization, revealed the presence of clay facies (kaolinite), sandy facies and mixed sediments, all covered with the earth bar. As for the size, it indicates coarse to medium sands with a positive asymmetry to almost positive, sands moderately classified to fairly classify. The relative mineralogy reveals the presence of silicon, aluminum and iron oxides. XRD indicates that quartz and kaolinite prevail and gypsum, rutile or anatase, illite and calcium sulfate hydrate are associated minerals.
