Propiconazole, a highly effective foliar fungicide has been successfully developed for the control of disease complex in cereals. The active ingredient (propiconazole) 1-(2-(2,4-dichlorophenyl) 4-propyl-1, 3-dioxolan-2-yl-methyl)-1H-1,2,4-trazole, inhibits fungi by interfering with ergosterol biosynthesis. The active ingredient is observed by the assimilating parts of the plant and transported acropetally. The systemic movement assures protection of actively growing parts of the plant. Propiconazole is protected from wash-off by rain or irrigation and provides control for 2-4 weeks, depending on the pathogens, disease pressure, and the carrier used. Under local conditions, propiconazole at 0.33% a.i. concentration applied by fixed wing aircraft every 21 days gave satisfactory control of Black Sigatoka. At present propiconazole is registered as Tilt 250 EC for use in controlling Black Sigatoka in Cavendish banana.
