FMC Metric 25ZC

Metric is a pre-mix of two broad spectrum herbicides i.e. Metribuzin and Clomazone .
Metribuzin is a selective herbicide of the chemical class the triazines. Metribuzin can be applied
as a foliar spray or soil treatment in order to control pre-emergence and post-emergance broadleaf
weeds and annual grasses. Metribuzin also has a residual effect on the soil. Metribuzin is primarily
absorbed by the roots, but also by the leaves to a lesser extent. It is translocated acropetally in the
xylem to the leaves where it has its effect. The mode of action of metribuzin is that it acts by inhibiting photosystem II of photosynthesis by disrupting electron transfer. This results in death due to starvation in the target plant and the Clomazone is a broad spectrum herbicide used for control of annual grasses and broadleaf weeds in cotton, peas, pumpkins, soybeans, sweet potatoes, tobacco, winter squash and fallow wheat fields. It can be applied early preplant, preemergent or preplant-incorporated depending on the crop, geographical area and timing. Because clomazone is an inhibitor of plant pigments, users must exercise caution to avoid drift or vapors which may cause bleaching damage to non-target foliage. Clomazone is available in emulsifiable concentrate formulations.
