| Résumé : |
Striga species are important as endemic pests of cereals, including sorghum, maize and upland rice, grown in the semi-arid tropical and equatorial regions of Tanzania. The distribution of striga species of economic importance in the country has been surveyed and the most frequently-observed species included S. asiatica, S. hermonthica and S. forbesii and each has been found to have a different range, some of which overlap.
Farmers interviewed recognized Striga as a major constraint in cereal production and they requested an immediate solution to the problem. Preliminary results from on-farm trials have shown that early-sown cereal crops yielded more than late-sown ones, despite higher Striga infestation in early-sown crops. Sorghum or maize intercropped with coupea (the spreading type) in the same row had the least striga emergence, and the highest sorghum grain yield was obtained from this treatment.
