PITAI
Metribuzin 70% W.P. (Selective Herbicide)
Description
It is a selective weedicide for the control of weeds in sugarcane, potato, tomato, soyabean, and wheat.
Metribuzin acts on roots and leaves and can therefore be used for both pre- and post-emergence applications. When used as pre-emergence, it is essential that the soil is clodless and has sufficient moisture (5–10%), as in the case that the product acts only through roots.
