General Product Information

Category

Fungicides > Strobilurin fungicides
Fungicides > Amide fungicides

Activity

A rice fungicide that is highly effective control of leaf and panicle blast (Magnaporthe grisea) and sheath blight (Thanatephorus cucumeris) in rice. It was discovered and developed by BASF. Its biochemical mode of action is the inhibition of the mitochondrial respiration chain by binding to the cytochrome bc1 complex at the Qo site. Orysastrobin shows an excellent plant selectivity in all tested rice varieties and is root systemic with an acropetal translocation. The active ingredient is formulated in granules with optimised release patterns, suitable for either seedling box or field applications. Orysastrobin provides an outstanding, consistent, and season-long efficacy against leaf- and panicle blast and sheath blight under different environmental conditions

CropUse

Rice.
For seedling box applications, orysastrobin will be registered with 700 g a.i./ha in combination with insecticides and for field application as a solo-compound with 660 to 990 g a.i./ha.

Disease Spectrum
