1. Biological control of the cassava mealybug involved the classical approach, from foreignexploration, biological studies, mass rearing, and release to monitoring and impact studies. The special attention given to quanfity observations on all trophic levels in a holistic approach transformed the...
  2. Improvements to traditional storage systems for fresh yam tubers are possible. These must begin at the time of harvesting when tubers should be handled carefully so that uninjured tubers can be put into storage. Small technical improvments to keep away pests, to improve the climate in storage and...
  3. 1995-01-01 Sound crop and soil management such as the use of fertilizers and lime, pest and disease control, optimum planting densities and patterns, selection of appropriate crop varieties among others are fundamental to diminish soil erosion and achieve greate ryields. From the study it may be concluded...
  4. This manual contains information on Production constraints, Strategies, Post Harvest Technology and Research on Cassava in Africa.
  5. 2016-01-25 Some tropical crops contain cyanogenic glycosides, toxic substances that release hydrocyanic acid (HCN; also referred to as cyanide or prussic acid) when cells are crushed. Consuming these plants without cooking them can cause cyanide poisoning, with varying effects depending on cyanide levels...
  6. 2015-02-16 Tropical root and tuber crops are consumed as staples in parts of the tropics and should be considered for their potential to produce impressive yields in small spaces. They provide valuable options for producing food under challenging growing conditions. Cassava and taro, for instance, are...
  7. 2005-10-01 An article by Francis Hallé in Nature and Resources, Volume 32, Number 3, 1996, explains several techniques used to “improve, select, propagate or preserve plant growth.” These techniques are called “phytopractices.” Most of them are inexpensive and simple to use but labor-intensive. The...
  8. 2005-10-01 Konzo is an irreversible disease that appears suddenly and causes spastic paralysis of both legs. Konzo affects mainly women and children, afflicting thousands in the remote rural areas of Bandundu Province in the Democratic Republic of Congo. It has also been reported from remote rural areas in...
  9. 2005-10-01 In Cassava Cyanide Diseases News (CCDN), Issue 4,December 2004, Dr. J. Howard Bradbury wrote about a method of processing cassava that could substantially reduce the cyanide content of flour.
  10. 2015-11-20 Some tropical crops contain cyanogenic glycosides, toxic substances that release hydrocyanic acid (HCN; also referred to as cyanide) when cells are crushed. Consuming these plants without cooking them can cause cyanide poisoning, with varying effects depending on cyanide levels and how long a...
