Beam^® is a recommended for the control of blast disease of rice.
It provides control against blast incidence that occurs at various growth stages of rice crop viz., leaf blast, stem blast and panicle blast.
As per Integrated disease management principles, in addition to Beam^®application, emphasis on field sanitation and optimum use of nitrogen fertilisers also helps in reducing the disease incidence.

Beam^® contains the active ingredient, Tricyclazole, belonging to melanin biosynthesis inhibitors.
Beam provides best control of blast at all growth stages.
It has prophylactic action.
Highly systemic with xylem mobility-good leaf and root uptake
No resistance issues reported till date

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.
It does not allow the fungus to establish by preventing its entry into the plant system.
It 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.
