Technical Name ; Tricyclazole 18 % + Mancozeb 62 % WP
It is a unique combination of systemic and contact fungicides. Its systemic part is Tricyclazole which is a specialty systemic fungicide. It is rapidly absorbed by the plants and translocated towards leaf tips. It is a protectant fungicide that prevents the fungus from penetrating the plant. Inhibition occurs when the fungus attempts to penetrate and establish an infection site inside the plant. In rice blast, the melanin pigment is needed for the hardening of the appressorium and inhibition of the pigment formation in appressorium makes it unable to mechanically penetrate the host plant. Its other partner is mancozeb which is a contact broad-spectrum fungicide with protective action. It is fungi toxic when exposed to air. It is converted to an isothiocyanate, which inactivates the sulphahydral (SH) groups in enzymes of fungi. Some times the metals are exchanged between Mancozeb and enzymes of fungi, thus causing disturbance in fungal enzyme functioning.
For better disease management, it is always advisable to remember the maxim – PREVENTION IS ALWAYS BETTER THAN CURE. Generally the sprays of Comrade should start before the appearance of disease or at disease initiation. Repeat the applications at 7-12 days interval depending on climatic conditions and disease severity. For blast control in paddy where both leaf and panicle blast exists, two applications are normally required, first at the time of appearance of lesions on leaves and second from late boot to 5 % panicle emergence. If bad weather persist, it is advisable to go for another application at 50 to 75 % of panicle emergence but before the panicle neck gets exposed to air.
