Striga: small seeds, big losses Striga, a parasitic weed of most savannah crops, is gaining ground in Africa and farmers have only limited weapons against it. Its control should therefore be added to the list of priorities for research . Farmer awareness At the present fume, farmers have only one option; to pull out the weeds by hand and burn them before they produce seeds. But this method is difficult to carry out except on very small plots and it will not be readily accepted by farmers who do not understand the relationship between the pretty pink flowers in their fields and the withering of their crops. In some areas, farmers think that they can win by changing crops. When sorghum is too badly infested they plant millet. But after a few years, millet becomes infested as well and farmers have to abandon their fields. It is therefore essential to improve their knowledge so that they can at least limit damage due to striga, while research workers identify the weaknesses of this parasite and suggest more efficient control methods. Striga exposed A bilingual (English and French) poster has just been published to familiarize extension workers with the threat striga represents to crops. Using drawings and pictures, it shows the stages of underground and above ground development of the parasite as well as the different striga species. A short strip cartoon gives practical advice for its control.
