Sub-Saharan farmers to fight Fall Armyworm with new digital weapon

The fight by sub-Saharan farmers against the Fall Armyworm pest, which has devastated crops and threatened food security for 300-million people, has gone digital. The United Nations (UN) has reported that the new weapon which was launched by the Food and Agriculture Organisation (FAO) and Pennsylvania State University, is a talking mobile phone app named Nuru which can identify the insect which is in fact a caterpillar.
