Abstract : In order to evaluate the fungicidal effect of medicinal plant essence and comparison of chemical fungicides to raise the post-harvest life of mango (Mangifera indica c.v Langra), saw experiment and performed in completely randomized design with 14 treatments and 10 replicates. The treatments consisted of control (without treatment), Putrecin (1, 3 and 6 mmol for 2 min), essence of Indian Clove and Rosemary (500, 750 and 1000 mg/l), warm water at 54°C and Thiabendazol fungicide (0.5, 0.75 and 1.0 mg/l for 3-5 min). After treatments, the fruits were stored in a refrigerator with 10°C temperature and 85-90% relative humidity. 30 days after storing, the characters such as weight loss percent, loss firmness percent, increased vitamin C percent, loss total acid percent, increasing total soluble solid (TSS) percent and increasing pH percent were measured. Result showed that the qualitative and quantitative characteristics of mango c.v Langra influenced by the treatment type. According to the obtained results, the least weight loss percent was observed in Indian Clove 750 mg/l. Variety of treatments had significant influence and the least amount of firmness loss was seen in Rosemary 500 mg/l treatment. The highest increasing amount of TSS was observed in hot water treatment and the least in Putrecin 6 mmol. The greatest increasing vitamin C was observed in Rosemary treatment.
