Inhibitory effect of Polyram DF and Capsicum annum on leaf spot of rose caused by Curvularia lunata in vitro and in planta

Rose plants are affected by several diseases caused fungi, nematode, bacteria, viruses, and other pests. Among all of these, Curvularia lunata causes significant losses to Roses. Present study was focused on In-vitro In-vivo management the “Curvularia leaf spot Rose” using different fungicides phyto-extracts. Diseased samples were collected from floriculture area University Agriculture, Faisalabad for isolation pathogen. Five i.e., Cabrio-Top, Curzate-M, Aliette, Polyram-DF Recado @ (50ppm, 100ppm 150ppm) five plant extracts Allium cepa, Capsicum annuum, Aloe vera, Menthaand Calotropis gigantean with three concentrations (5%, 10% 15%) evaluated under lab conditions through poisoned food technique Complete Randomized Design (CRD), where C. annuum gave best results (9.129mm) followed gigantea (13.003mm), effective (2.218mm) Curzate-M (6.542mm). Best performing plant-extracts subjected trials. Under green-house conditions, combination + shown least disease incidence (14.517 3.224%). LSD used comparing variations between treatments at 5% probability. The these experiments aid in evaluation Phyto-extracts, which most chemicals phyto-extracts against Spot Rose.
