The menace of Striga hermonthica, a parasitic weed with no record of infestation in the rainforest regions of Nigeria is highly prevalent in the dry Sudan Savanna regions of the country with adverse detrimental effects on cereals production. It is usually hypothesized that S. hermonthica will not strive in the southern soil due to the abundant rainfall in the region. Thus, this study aimed to determine the survival rate of S. hermonthica seeds on different soil types in Edo State, Nigeria. The experimental layout consisted of 20 S. hermonthica seeds sown in 5 kg polythene bags each consisting of 5 different soils namely; control, Soil A, Soil B, Soil C and Soil D respectively, replicated 5 times in a randomized block design. From the data, Striga germination rate was significantly increased in Soil C from the rainforest zones as compared to Soil D (endemic soil from the dry Sudan Savanna region). High rate of germination was also observed in the distilled water treatment which showed the viability of the Striga seeds. In the field trial, S. herminthica only survived in Soil C and Soil D 5 weeks after exposure into the various soil type with the highest emergence rate and senescence of the Striga weed recorded in Soil C which increased with time. Hence, this study have established a significant baseline platform on the infestation of soils in the rainforest zone of Nigeria by S. hermonthica and employs all policy makers to implement control measures to mitigate its spread.
