Tricyclezole is a recommended fungicides for the control of blast disease of rice. Tricyclezole provides control against blast incidence that occurs at various growth stages of rice crop viz., leaf blast, stem blast and panicle blast.

Tricyclazole inhibits polyhydroxynapthaline reductase enzyme and thus inhibiting melanin formation in fungi (Pyricularia grisea).

In the absence of melanin, appressoria fails to produce penetrating hypha or penetration hypha fails to penetrate into host tissue. Hence disease is not allowed to spread.leaf blast, rice leaf blast

It does not allow the fungus to establish by preventing its entry into the plant system.
Tricyclazole is highly systemic in action thus it is rapidly gets absorbed by rice leaves and roots and is translocated toward the leaf tip which suggests its xylem transport.

There is also movement from a treated leaf to non-treated younger leaves.

Benefits of Using Tricyclezole:

  • Tricyclezole is belonging to melanin biosynthesis inhibitors which provides best control of blast at all growth stages.
  • Tricyclezole has prophylactic action.
  • Highly systemic with xylem mobility-good leaf and root uptake
  • No resistance issues reported till date
