Ratna Blast
Propiconazole 10.7% + Tricyclazole 34.2% SE
Ratna Blast (Propiconazole 10.7% + Tricyclazole 34.2% SE) is a targeted combination fungicide from Ratnakar India Ltd, Ahmedabad — India's trusted agrochemical manufacturer, supplier, and exporter. Specifically formulated for rice, the combination of Propiconazole (DMI triazole, ergosterol inhibitor) and Tricyclazole (melanin biosynthesis inhibitor) provides comprehensive control of Sheath Blight and Blast — two of the most damaging rice diseases. The SE (Suspo-emulsion) formulation offers excellent stability and coverage. Manufactured and exported by Ratnakar India from Gujarat, Ratna Blast is a precision fungicide for rice farmers seeking reliable, dual-mode protection against both Blast and Sheath Blight in paddy crops.

FAQ for Ratna Blast
What diseases does Ratna Blast control?
Ratna Blast controls Sheath Blight (Rhizoctonia solani) and Blast (Pyricularia oryzae) in rice — two of the most economically important fungal diseases causing major yield losses in Indian paddy cultivation.
How do the two actives in Ratna Blast complement each other?
Propiconazole controls Sheath Blight by inhibiting ergosterol biosynthesis in Rhizoctonia, while Tricyclazole specifically prevents blast fungus penetration by inhibiting melanin biosynthesis — together covering both critical rice diseases.
When should Ratna Blast be applied in rice?
Apply Ratna Blast at tillering stage for Sheath Blight control and at panicle initiation for Blast protection. For best results, apply preventively during disease-conducive humid weather conditions.
Is Ratna Blast suitable for rice in flood-prone areas?
Yes, Ratna Blast is suitable for rice in diverse agroclimatic conditions. The SE formulation provides good rainfastness and adhesion, maintaining efficacy even in high-humidity paddy environments.
What is the advantage of SE formulation in Ratna Blast?
The SE (Suspo-emulsion) formulation combines advantages of both SC and EC — providing excellent physical stability, reduced solvent content, good rainfastness, and superior spray coverage on rice crops.
