This document summarizes research on minimizing post-harvest losses of horticultural crops through the use of chemical, biocontrol, and natural plant products. It discusses that post-harvest losses in fruits can range from 5-50% in developing countries. Several chemical treatments are described that can extend shelf life, including potassium permanganate, hydrogen peroxide, maleic hydrazide, and methylcyclopropene. The use of biocontrol agents like Trichoderma spp. and Paecilomyces variotii are also summarized. Finally, the document outlines natural plant products including neem, lemon grass, and turmeric that have antifungal properties and can reduce post-harvest losses when used as treatments on
