Abstract:
Traditional approaches for the management of various post-harvest diseases involving
synthetic or chemical preservatives have raised concerns regarding their impact on human
health and the environment. In this study, we propose novel and sustainable management
practices using a leaf layer as a natural barrier to manage post-harvest anthracnose and extend
the shelf life of mango fruits, which offer a promising alternative to the conventional use of
chemical fungicides. Therefore, this study was conducted at the Department of Plant
Pathology, N. M. College of Agriculture, NAU, Navsari during the year 2022 to find out the
effect of different botanicals on the suppression of anthracnose disease and its effect on the
shelf life of mango cv. Kesar. Among the evaluated different treatments, fruits covered with
neem leaves showed lowest disease incidence (30.00%) which was at par with fruit covered
with lantana leaves (33.33%) followed by fruit covered with marigold leaves (40.00%) as
compared to control (80.00%). The shelf life was significantly found higher (13.33 days) in
fruit covered with neem leaves followed by fruit covered with lantana leaves (12.00 days) as
compared to control (7.00 days). The aroma and volatile compounds emitted by various
leaves create a thin film and delicate layer around the fruit, acting as a natural repellent and
antifungal agent. This protective film serves to deter pathogens from entering, penetrating,
and attacking the fruit. The utilization of botanicals or plant-based materials for fruit
preservation is considered safer for both humans and the environment compared to synthetic
or chemical preservatives. Consequently, botanicals could serve as a substantial alternative to
chemical pesticides for management of post-harvest diseases. They are not only eco-friendly
and efficient but also cost-effective, ensuring the safety of consumers and the environment.
