Pests and diseases are the number one reason for crop yield loses around the world and the number one threat to food security in the developing world.Estimates suggest that as much as 35% to 50% of food production is lost to pathogens, insects and weeds. Smallholder farmers in developing coutries are perhaps the hardest hit, as they can not afford chemical control measures and are more vulnerable to loss of food or income. Ironically, massive pesticide usage in developed countries does not reduce losses to low levels. Recognition of this has led many to argue for a more ecological approach based on understanding interactions between planned and unplanned biodiversity.
