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 É importante arrancar a estriga daninha com as mãos antes que elas produzam sementes e se espalhem. Como isso é trabalhoso, aconselha-se reduzir o número de estrigas, aplicando composto ou esterco e rotacionando ou consorciando com culturas não cerealíferas, como...

Access Agriculture Training Video O composto é mais poderoso do que o esterco. O que poucos sabem é que os microrganismos do composto atacam as sementes da estriga no solo. O composto também diminui a quantidade de estriga que brotará e reduz seu efeito negativo nas plantações de cereais. Vejamos...
