Striga
S. asiatica is a hemiparasitic plant, native to Africa and Asia. In common with most other parasitic weeds, it is not especially invasive in natural vegetation, but is much feared in crop land where infestations can build up to ruinous levels, especially with repeated growing of susceptible cereal crops. For this reason it is included in almost all lists of noxious, prohibited plant species. It has recently been reported in Queensland, Australia. There is also evidence for its continuing spread and intensification within a number of countries in Africa in particular in rice in Tanzania and maize in Malawi. A study by Mohamed et al. (2006) suggests that on the basis of climatic data, there are many territories into which Striga species, including S. asiatica, could be introduced and thrive. Global warming could further increase this potential. --- CABI

In the Push-Pull system, crops that repel pests and/or attract pests’ predators are intercropped with maize, to ‘push’ pests away from the main crop. Plants that attract pests are planted around the field, to ‘pull’ pests away from the maize. Incorporating legumes in this system means that soil...

Access Agriculture Training Video Compost is more powerful than manure. What is less known is that the micro-organisms in compost attack striga seeds in the soil. Compost also decreases the amount of striga that will sprout, and reduces its negative effect on cereal crops. Let us look at how...
