Abstract

Downy mildew caused by Pseudoperonospora cubensis is a major foliar disease in cucumber which causes more damage and devasting loses to cucumber production.In the present study revealed the biological management of downy mildew disease in cucumber.The in vitro studies presented that, garlic bulb extract at a concentration of 15% revealed greater percentage inhibition (71.42%), followed by clove oil (64.51%), between all the botanicals studied Pseudomonas fluorescence inhibited sporangia germination powerfully (58.137%), followed by Trichoderma harzianum (46.67%). in vivo results also confirmed that, garlic extract @10% found to be best in decreasing the downy mildew incidence (42.28 %) with lowest AUDPC value (1278.51)compared with control plants and the next best was clove oil @ 4% (47.77%).However, The minimum disease incidence was observed in POP (UHS, Bagalkot) recommended fungicide Ridomil gold @ 0.2% sprayed plants (41.19%) with lowest AUDPC value (1143.94).The bio control agent Pseudomonas fluorescens was found to be less operational under field conditions (55.39%), when compared with other treatments and control (86.37%).
