| Efficacy of five systemic fungicides (flusilazole, propiconazole, diniconazole, cyproconazole and tetraconazol) in curbing powdery mildew disease of wheat (Sakha93) and its impact on yield components were evaluated under field condition during two successive season. Both fungicides, propiconazole and diniconazole exhibited the highest value of efficacy (88.80% each) recording the lowest rate of disease infection (1 each). The contrast was noticed with tetraconazol (55.50% efficacy, 4 disease infection) with significant differences to untreated control during both seasons. The results of fungicide application reflected on yield components where 1000-kernel and 1000-ml weights recorded the highest values with propiconazole (49.03 g and 742.65 g) followed by... |
