This course describes cereal postharvest losses in SSA and APHLIS, the African PostHarvest Losses Information System, which provides science-based estimates of the postharvest loss levels where direct measurements are not available.
This first course introduces the full series of APHLIS courses on rapid postharvest loss assessment measurement, and presents the objectives.
This course in the APHLIS series on postharvest loss measurements introduces you to the creation and use of visual scales to facilitate and speed up the estimation of losses during storage.
The course explains how to use a visual scale and in what context; how to define the quality classes that make up the visual scale; how to create examples of these quality classes and present them in transparent boxes, dishes or bags for use in the field.
To collect the local information needed to create the visual scale you will need to work with informants. Your visual scale will need to be used by the enumerators once you have trained them.
Finally, the course describes the data to be recorded at each stage.
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.
