The importance of mangrove swamp rice cultivation in Sierra Leone and in the West African subregion in general is defined and diseases occurring are listed and discussed including some indication of their economic importance. Generally it was observed that disease severity was less pronounced under this cultivation than in other types of rice growing areas. Several factors were considered responsible for this phenomenon, namely: the non-use of nitrogenous fertilizers in mangrove swamp rice fields by the farmers; the breezy nature of the swamp environment which leads to faster drying up of water drops on the rice plant thus inhibiting the infection process; and the low pH and salinity, which, particularly in the off-season, is thought to reduce the number of viable propagules of several rice pathogens. Rokupr was found to be suitable for the screening of rice varieties resistant to rice blast (Magnaporthe grisea (Hebert) M. E. Barr) due to the presence of a rich flora of races of the fungus. A strategy for disease control in the mangrove swamp agroecosystem is proposed. |
