Powdery mildew is the one of the most severe and devastating disease of roses under protected cultivation. So under this study we have tried different ecofriendly approaches to manage the disease with the use of seven biological control agents (BCAs), nine bio-products and eight plant extracts. Under In vitro studies the highest efficacy was obtained with Bacillus subtilis, neem oil and Allium sativus at their higher concentrations. Among the BCAs the highest disease control was observed in Ampelomyces quisqualis (78.51%), Bacillus subtilis (74.12%), Verticillium lecanii (70.55%) and Trichoderma harzianum (67.33%) under the greenhouse conditions. From the bio-products best disease control was obtained with neem oil (76.18%) at 5% concentration. The best disease control was obtained with plant extract of Allium sativus (71.87%) at 20% concentration.
