Management of post-harvest pathogens of Nagpur mandarin through chemicals, oils, wax and bio-agent

Abstract

Effect of fungicides, chemical, oils, wax and bio-agent against postharvest pathogens of Nagpur mandarin was evaluated for their inhibitory effect in vitro. After 24 hours, Carbendazim @ 0.1 percent was found superior in inhibiting the conidial germination (87.26%) of Colletotrichum gloeosporioides, after 48 hours it was (81.11%) and after 72 hours inhibition was (75.90%) recorded. Highest conidial inhibition of Geotrichum candidum found in Hydrogen peroxide @ 10 percent was (91.04%), (84.76%) and (77.59%) after 24, 48 and 72 hours respectively. After 24 hours Carbendazim @ 0.1 percent was effective in restriction (88.68%) of conidial germination of Aspergillus niger at 48 hours inhibition was (84.78%) recorded and after 72 hours, it was (80.26%). Carbendazim @ 0.1 percent was found superior in inhibiting the conidial germination (92.88%) at 24 hrs of Penicillium digitatum, while at 48 hours it was (86.44%) and after 72 hours it was (80.83%). Highest conidial inhibition (85.14%) of Trichoderma viride was achieved in Carbendazim 0.1 percent at 24 hrs and after 48 hours it was (78.32%) while, after 72 hours, conidial inhibition was (72.53%).
