Abstract


Fungal diseases affect both the productivity and sustainability of wheat crop. The aim of present study was to document the fungal diseases of wheat crop and biological management of a most dominant fungal pathogen Alternaria solani by using medicinal plant extracts. Fungal infected wheat plants were collected from different sites of District Bhimber, Azad Jammu and Kashmir (Sukasan, Kool, Gurha Liliyan, Gurha Matyal, Dheri Wattan, and Pothi) and these fungal infected wheat plants were examined under field and greenhouse conditions by using four different plant extracts to check the severity rate of fungal diseases. Three contagious species were isolated from regularly contaminated wheat leaves and other natural items demonstrating the indications of scourges and most dominant species recognized as A. solani. The antifungal action of four plant’s leaf solutions including Nerium oleander (Oleander), Allium sativum (Garlic), Ocimum basilicum (Sweat Basil) and Eucalyptus chamadulonsis (Eucalyptus) have been attempted to control Alternaria solani in an artificial medium and in natural conditions. In an artificial medium, decoction of Allium sativum bulb at 5% fixation caused the most noteworthy lessening in mycelial improvement of A. solani (40.2%), while Ocimum basilicum at 1% and 5% fixation and Nerium oleander at 5% fixation the most decreases obstruct the mycelial advancement of the microorganism. In nursery analyzes, the most serious diminishing in contamination seriousness was brought about by the bulb extract of Allium sativum on 5% fixation as well as Nerium oleander on 1% and 5% fixations. The best decline in infection seriousness was accomplished with Allium sativum on 5% fixation, but the slightest decrease was observed after treatment of wheat plants with Nerium oleander on 1% and 5% application (22.3% and 30.2%, respectively). Allium sativum at 5% application expanded natural product yield by 35.2% and 40.2% as opposed to contaminated control. It was concluded that all selected medicinal plants reduced the selected disease and furthermore upgraded grain yield as opposed to contaminated control in field crop diseases especially Alternaria solani attack on wheat.
