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

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 which infect(s) yam Dioscorea cayenensis-rotundata.

Fungicidal Effect of Some Plant Extracts against Tuber Dry Rot of White Yam (Dioscorea Rotundata Poir) Caused by Aspergillus Niger

International Journal of Horticulture & Agriculture, 2018
In vitro study was carried out to test the efficacy of Azadirachta indica A. Juss. (Neem), Nicotiana tabacum Linn. (Tobacco), rhizomes of Zingiber officinale Rosc. (Ginger) leaves of Carica papaya Lam. (pawpaw) and seeds of Piper nigrum Linn. (Black pepper) and a chemical fungicide (mancozeb) at three concentrations of plant extracts (30, 60 and 90 g/L)

Organic-matter effects on populations of dry rot of yam nematodes

African Journal of Agricultural Research, 2016
The objective of this study was to evaluate the effect of organic-matter incorporated into the soil on population densities of the causal agents of the dry rot disease of yam, under field conditions. The experiment was performed in a natural infested area with a mixed population of Pratylenchus coffeae and Scutellonema bradys, in Quebrangulo county ...
