Katyayani Penza is a selective herbicide for the control of susceptible annual grasses, sedges and broad-leaved weeds in Soybean crops. Katyayani Penza combination is used to control major plant incorporated, pre-emergence or post emergence. It also controls annual grasses , sedges and broadleaf weeds and they germinate. It is recommended to use in Soybean Echinochloa Colona, Marsilea Quadrifolia, Rice, Cotton Groundnut Etc . PENZA contains Pendimethalin which is a selective herbicide which is absorbed by the roots and leaves. Affected plants dies shortly after germination or following emergence from the soil. Imazethapyr is a systemic herbicide, it is absorbed by the roots and foliage, with translocation in the xylem and phloem, and accumulation in the meristematic regions.Katyayani Penza is absorbed by the roots and leaves. Affected plants die shortly after germination or following emergence from the soil.belongs to the family of dinitroaniline. It works as a microtubule assembly inhibitor. Imazethapyr belongs to the family of imidazolinone, it is a branched chain amino acid synthesis inhibitor. Hence it reduces the level of important amino acids like valine, leucine and isoleucine to disrupt the proteins and DNA synthesis. Selectivity in soybeans and peanuts is attributed to rapid detoxification via hydroxylation and glycosylation.
