14. Prospects for traditional and cultural practices in integrated pest management of some root crop diseases in rivers state, Nigeria.

In: Proc. of a Workshop for Integrated Pest Management of Root and Tuber Crops in the Tropics; IITA, Ibadan, Nigeria, 1987, pp. 185-187

In this paper evaluation was made of the role of traditional and cultural practices in controlling yam storage rot and cassava stem cutting rot in the soil in Rivers State.

Rivers State lies in the lowland rain forest belt of south-eastern Nigeria. The environment also creates favorable conditions for the development and spread of numerous plant pathogens.

Healthy, fairly uniformly-sized and newly harvested whole yam (Dioscorea rotundata var. Gboko) and palm oil were purchased from the local markets. Five of the yams were cut transversely into ten equal halves.

Each of the ten cut surfaces was thoroughly smeared with 5 ml unsterilized palm oil and kept in an upright position for about 60 min to prevent the oil from dripping. To serve as the control, the remaining five tubers were similarly cut but the surfaces were left untreated.

They were also held in a vertical position for 60 min.

All the tubers were later randomly spaced horizontally inside a wire-netted wooden box in the laboratory for protection against cockroaches and rodent attack. Observations were made of biodeterioration in the yam samples and at the end of 10 weeks each half-tuber was cut vertically into two to measure the depth of rotting.

Yam tubers which were treated with unsterilized palm oil resulted in less rotting by supporting fewer pathogens and by preventing formation of cracks which could serve as entry points for pathogens. Thus palm oil apparently had properties which protected stored yam tubers from rot.

Concluding the traditional and cultural control of the root crop diseases discussed in this paper could be adopted to supplement other control measures in farms and stores. These methods are cheap and feasible and within reach of peasant farmers.
