Plant Pathogenic Bacteria Studies

The current research aims to find out different effective and suitable fungicides, botanical extracts and bio-control agents against Cladosporium cladosporioides, the causal agent of Cladosporium rot in grapes. For this purpose, different fungicides including, Antracol, Alliette, Melody duo, Cabriotop and Topsin-M at the rates of 100, 200 and 300 ppm, as well as botanical extracts including, Garlic, Ginger, Onion, Eucalyptus and Neem at the rates of 5, 10 and 15% were tested using food poisoning method. Bio-control agents such as Pestalotiopsis sp., Neurospora sp., Fusarium sp., Arthrinium sp. and Hypocrea lixii were also evaluated against the pathogen. Pathogenicity test was also performed to see the disease severity in grapes. Minimum linear colony growth of C. cladosporioides was observed as 39, 30.5 and 21 mm for Melody duo, respectively followed by Antracol (38.5, 30.5 and 23), Alliette (39, 31.5 and 23.5), Topsin-m (42, 33 and 27.5) and cabriotop (43.5, 36.5 and 26), as compared with the control, which was 90 mm. Whereas Minimum linear colony growth of C. cladosporioides was observed as 50, 32.5 and 19 for Neem, respectively followed by Ginger (56.5, 36.5 and 22.5), Garlic (61, 39 and 24), euclayptus (62, 41.5 and 25) and Onion (64, 43 and 25), maximum linear colony growth (90) was observed under control. Whereas, the minimum linear colony growth of C. cladosporioides was observed for Neurospora sp. (3.7), followed by Arthrinium sp. (7.5), Pestalotiopsis sp. (9), Hypocrea Lixii (9) and Fusarium sp. (9.5), maximum linear colony growth (90) was recorded in control. This study could be helpful for researchers and farming community in future for better management of this disease.
