In Pakistan and around the world, stripe rust on wheat leads to substantial production losses. The current study was undertaken to assess different wheat genotypes at Hafizabad Research Farm, College of Agriculture, University of Layyah, during the 2022-23 cropping season. Among the 15 genotypes screened, three exhibited a resistant response to the yellow rust pathogen. The disease progress curve (AUDPC) was calculated for all genotypes in the area. Environmental factors significantly influenced the severity of yellow rust. A positive correlation was observed between environmental variables, such as maximum and minimum temperatures, relative humidity, rainfall, and disease severity. Simple linear regression analysis indicated that the severity of yellow rust increased with rising maximum temperature, minimum temperature, rainfall, and relative humidity: 15.3-24°C, 9.9-16.6°C, 8-16 mm, and 20.7-70.7%, respectively. In the subsequent study, four fungicides were employed to control yellow rust, mitigate yield losses, and enhance the marginal return of wheat varieties. Among these fungicides, Tilt and Score demonstrated the highest efficacy in yellow rust management. In conclusion, the screening and fungicidal management of yellow rust on wheat genotypes have the potential to foster rust resistance and maximize production.
