Crop And Plant Diseases Entail Serious Implications For Food Security And Production Losses. Over The Years, The Lasting Global Trade And The Changing Climate Have Not Only Exacerbated The Existing Favorable Conditions For Plant And Crop Disease But Have Also Created New Conditions With Which Agriculture Must Now Contend. As The Food And Agriculture Organization Of The United Nations (FAO) Asserts, Plant Pests And Diseases Are Responsible For Losses From 20% To 40% Of Annual Global Food Production. This Means That Timely Disease Management Will Be Necessary In Order To Address The Increased Food Demand Caused By Population Growth. In This System, We Present An Analysis And Classification Of Research Studies Conducted Over The Past Decade That Forecast The Onset Of Disease At A Pre-symptomatic Stage (i.e., Symptoms Not Visible To The Naked Eye) Or At An Early Stage. We Examine The Specific Approaches And Methods Adopted, Pre-processing Techniques And Data Used, Performance Metrics, And Expected Results, Highlighting The Issues Encountered.
