Abstract
Barley diseases pose significant challenges in no-till agricultural systems. This study aimed to evaluate the effectiveness of combining seed and foliar treatments for managing barley diseases within a no-till system in Morocco and to provide practical recommendations for sustainable management. Conducted over two cropping seasons on a no-till platform in a semi-arid region, the treatments included seed treatment with tebuconazole and foliar application with a systemic fungicide (Spiroxamine + Tebuconazole + Triadimenol). Disease severity was visually assessed at emergence, before treatment, and one-week post-foliar application. In the first season, seed treatment reduced seedling dry weight without affecting disease severity or plant density. Both seed and foliar treatments significantly reduced disease severity in adult plants, by 50% with foliar treatment and by 27% with seed treatment. However, seed treatment decreased grain yield while increasing thousand-grain weight (TGW). In the second season, neither seed nor foliar treatments significantly influenced dry biomass, grain yield, or TGW, though foliar treatment increased the number of empty ears. Combining seed and foliar treatments showed no additional benefits for disease control or yield in both seasons. The results indicate that foliar treatments are more effective than seed treatments for managing barley diseases, particularly in years with higher disease severity. However, in seasons with low disease pressure, disease treatments in no-till systems may not be economically viable for farmers. These findings suggest that integrated disease management strategies should consider climatic variability to optimize treatment efficacy.
