Yam, a key food crop in Togo and tropical Africa, faces increasing threats from plant-parasitic nematodes such as Scutellonema bradys, Pratylenchus coffeae, and Meloidogyne incognita, which damage tubers and reduce yields. This study evaluates the efficacy of the "Wrap and Plant" technology, involving abamectin-impregnated banana paper, to mitigate nematode impacts on yam crops across 18 sites in three agro-ecological zones. Three treatments were tested: T1 (abamectin-treated matrices), T2 (untreated matrices), and T3 (traditional practices). Parameters assessed included sprouting rates, tuber weight, and nematode density in tubers, roots, and soil. Results showed no significant differences in sprouting rates or tuber weight across treatments and zones. However, significant differences were noted in AEZ I for nematode density in roots (P = 0.02) and tubers (P = 0.01), with T1 and T2 reducing nematode numbers in AEZ I and II. In AEZ III, traditional practices (T3) were more effective. The nematodes identified included Pratylenchus spp., Scutellonema spp., Meloidogyne spp., and Rotylenchus spp. The effectiveness of the technology varied by zone, showing promise under specific conditions, while traditional methods sometimes outperformed it.
