This course on phosphine fumigation presents the preparatory operations, the process of a good fumigation and post fumigation activities in order to effectively eliminate pests of stored grains. The course explains the precautions to take and details the essential protective equipment against phosphine gas. The course also describes the dangers associated with the use of phosphine during fumigation and introduces the notion of pest resistance to phosphine.
APHLIS courses : Measuring post-harvest losses
APHLIS is the "African PostHarvest Loss Information System". This system offers the best estimates of postharvest losses in Africa, for the most important cereals, legumes and roots and tubers.
Because direct measurements of postharvest losses are costly and complex, few good quality figures are available. For all the cases where such a good quality measurement is not available, a credible estimate is the best alternative.
APHLIS estimations of postharvest losses are mainly designed for decision-makers needing to invest development resources towards achieving food security through reduction of postharvest losses.
APHLIS estimates are based on loss figures that were measured scientifically and published in peer-reviewed literature, adapted by a transparent algorithm to various agro-ecological zones and local conditions. For more details, please consult: https://www.aphlis.net/
The APHLIS courses presented here are components of a toolkit developed by experts from the Natural Resources Institute (NRI) of the University of Greenwich. These courses are designed to train young agronomy technicians in the application of the APHLIS methodology for measuring postharvest losses. APHLIS uses this methodology to collect specific postharvest loss measurements in order to verify its estimates and also to add to their calculation and make them even more reliable. The loss measurement methodology has been developed, tested and refined by NRI scientists over decades.
