INTRODUCTION Mangoes are juicy stone fruit from numerous species of tropical trees belonging to theplant genus Mangifera, cultivated mostly for their edible fruit. The genus belongs to the cashew family Anacardiaceae. Mangifera indicahas been distributed worldwide to become one of the most widely cultivated fruits in the tropicsparts of the plant, namely, trunk, branch, twig, leaf, petiole, flower and fruit are attacked by a number of pathogens including fungi, bacteria and algae. They cause several kinds of rot and most importantly stem end rod which is of great economic importance as

they cause heavy losses in mango productiondisease is a destructive disease of mango and it is known to occur in India and other mango growing countries. Dothiorella dominicana, D. manqifera, Lasiodiplodiatheobromae, and Phomopsismanqiferae are the dominant fungi associated with stem end rot.
In fruit from drier areas, stem end rot may be a more serious post-harvest disease than anthracnose in mangoes. The peculiarity of the rot is that the disease initiates around the stem-end as brown round area and gradually spreads to the stylar end covering the entire fruit. Diplodia stem-by Diplodianatalensis is an important postharvest disease of ripe mango fruits.
There are many fungicides available in the market which are usually used for the stem end rot but these fungicides have side effects on human beings. Iorder to avoid these harmful effects natural methods can be used.
Materials and Method: 6 mangoes were taken, out of them three were effected by stem end rot and three mangoes were healthy each of the mangoes (one healthy and one diseased ) were kept in vinegar solution, baking soda solution and sugar solution. Few mangoes which were healthy were kept separately.
Result: The mangoes which were already effected by stem end rot spoilt completely, whereas the mangoes which were healthy had more shelf life than the mangoes kept separately without any medium. All the three media i.e. Baking soda,Vinegar and Sugar showed similar effect on the mangoes.

Discussion: Use of vinegar and sugar to prevent microbial growth is an ancient technique that remains important today for the preservation of foods. Baking soda is also used i many parts of the country to preserve foods. Vinegar is made from the fermentation of sugar and water solutions and is an effective natural preservative. The acetic acid in vinegar kills microbes and stalls food spoilage Bacteria evolved in environments where the concentration of sugars and salts is the same as or lower than those inside the cellHigh sugar concentrations cause the bacterium to lose water by osmosis and it doesn't have any cellular machinery to pump it back in against the osmotic gradient. This is also called as sugar curing.other antimicrobial mechanisms of sugar include interference with a microbe's enzyme activity and weakening the molecular structure of its DNA. Sugar may also provide an indirect form of preservation by serving to accelerate accumulation of antimicrobial
