Sweet Potato (Ipomea batatas L.): A New Alternative Host of Two Phytoplasmas Associated with Coconut Lethal Yellowing Disease in Côte d’Ivoire

Bognan Winnie Miyasi Ouattara, Kouamé Daniel Kra, Yadom Yao François Regis Kouakou, Marie Noel Yeyeh Toualy & Hortense Atta Diallo · Journal of Experimental Agriculture International · 2023

Aims: Coconut Lethal Yellowing Disease has been threatening coconut plantations in Côte d'Ivoire for ten years and has destroyed more than 400 ha. The destruction of the coconut palm leads to phytoplasmas conservation on other plants grown in association or near of the disease ou...

Inoculum Level and Inoculation Method Influences on the Pathogenic Activities of Meloidogyne incognita in Studied Model Plant Okra (Abelmoschus esculentus L. Moench)

Yadom Y. F. R. Kouakou, Kouamé Daniel Kra & Hortense Atta Diallo · Journal of Experimental Agriculture International · 2021

Agricultural activities such as watering crops with nematode-infested water from wells and boreholes, and using infected plant debris as manure or mulch increase root-knot nematode infection. So, this study aims at assessing the influence of the inoculation method and inoculum le...

Morphological Characteristics of Scutellonema bradys Populations Responsible for Yam Dry Rot in Côte d’Ivoire

Yadom Y. F. R. Kouakou, Kouamé Daniel Kra, Toualy Marie Noël Yeyeh & Hortense Atta Diallo · Journal of Advances in Biology & Biotechnology · 2021

The great diversity of agroecological factors that cover the yam production area in Côte d’Ivoire can be a source of morphological variability within Scutellonema bradys species, responsible for yam dry rot. This study aims at identifying the morphological group(s) of S. bradys w...

Fluctuation in Yam Nematodes Depending on the Phenological Stages of the Main Yam Species (Dioscorea alata L.) Cultivated in Côte d’Ivoire

Yadom Y. F. R. Kouakou, Kouamé Daniel Kra & Hortense Atta Diallo · International Journal of Plant & Soil Science · 2020

The telluric factors favorable to nematode pathogenic diversity make yam nematode control ineffective. This work aims at studying the fluctuation in yam nematodes depending on yam phenological stages. Trials were implemented in four yam production areas in Côte d'Ivoire. After in...
