[Denish Ochieng, Standard] Agricultural crops produce a bulk of the food we consume on daily basis and 100% of the food choices for the vegetarian Kenyan population. The yields of the crops we consume, however; are affected by a number of factors with weeds, plant diseases and pests largely responsible for the low yields of most crops in the country if not complete yield losses. Science defines crop protection as the science and practice of managing plant diseases, weeds and pests that cause damage to the crops.
