| Abstract | ||||
| Mango (Mangifera indica) is an important fruit crop of Egypt. There are significant postharvest losses. The application of antagonistic formulations bears enormous potential for managing the same, which has yet to be fully realized. Consequently, investigations were done for the application of Bacillus amyloliquefaciens, Bacillus pumilus, Bacillus firmus BMAT2, Bacillus subtilis, Trichoderma viride TV3 and Trichoderma viride TV6 on mango fruit under in-vitro and field circumstances to determine the efficacy of these antagonistic isolates on the postharvest pathogen. The percentage of inhibition in mycelial growth was attempted for in-vitro studies. In the field, mango fruits with major postharvest pathogen (anthracnose: Colletotrichum gloeosporioides) were treated with talc of Trichoderma viride, talc of bacteria, fungicide carbendazim (0.1%) and water control. The results show that under in-vitro experiments, fungal isolate TV3 and bacterial isolate BMAT2 were notably effective at inhibiting the pathogen. For field studies, the use of these formulations before harvest considerably enhanced yield parameters (number of fruits and fruit yield) as well as fruit quality (total soluble solids, ascorbic acid, total reducing and non-reducing sugar content and free acidity). The disease index of anthracnose was significantly reduced in the Talc T treatment. The preventive and control efficacy of Talc T treatment was 74.9% in the 1st season and 75.3% in the 2nd season. Talc T produced the highest amounts of phenolic content, polyphenol oxidase and peroxidase on mango foliage, flowers and fruits. Mango fruit's postharvest pathological loss can be managed with the Talc T treatment without compromising the fruit's internal quality. | ||||
