Integrated Management Strategies for Prevalent Diseases of Cucumber (Cucumis sativus L.) under Odisha Condition

Aim: To evaluate different integrated disease management modules against major diseases of cucumber (Cucumis sativus L.). Study Design: The experiment was laid out in a randomized complete block design (RBD) with 3 replications and 7 treatments including control. Place and Duration of Study: All India Coordinated Research Project on Vegetable Crops, Odisha University of Agriculture and Technology, Bhubaneswar during summer season of three consecutive years of 2015-16, 2016-17 and 2017-18.” Methodology: Included in this integrated approach are methods for controlling common cucumber diseases like downy mildew, cucumber mosaic virus and collar rot. These methods include growing border crops, using reflective mulches, applying soil amendments and spraying fungicides and insecticides. Results: “The results of the experiments showed that treatment comprising raising of two rows of maize as border crop in the main field 15 days before cucumber seed sowing along with sliver Agri mulch sheet, Seed treatment with carbendazim 12% + mancozeb 63% @ 3g/kg and drenching of captan 70% + hexaconazole 5%WP @0.1% at 15 days after germination followed by by spraying of Imidacloprid 17.8 [email protected] ml/15 L+ Neem oil @ 0.2% followed by captan 70% + hexaconazole 5%WP @0.1% followed by Fosetyl Al @ 0.1% followed by captan 70% + hexaconazole 5%WP @0.1% followed by spraying of Imidacloprid 17.8 [email protected] ml/15 L+ Neem oil @0.2% followed by Fosetyl Al @ 0.1% at 10 days interval was substantially reduced per cent incidence/intensity of different disease like collar rot (74.5%), downy mildew severity (69.2%) and mosaic incidence (65.2%) as compared to control.” Conclusion: The results give light on how farmers, who are experiencing a lot of trouble this summer owing to the onslaught of several diseases on cucumber crops, might increase yields by using these technologies. In addition to achieving a maximum B:C ratio of 3.5, the treatment combination also achieved the greatest economic return (Rs. 1,58,668) and fruit production (107.2 q/ha). As far as disease control strategies go, this integrated strategy seems to be both safe and environmentally sound.
