Six herbicides was tried into a terciary channel on heavy soil, it belong to the "Esmeralda" family in "Sur del Jíbaro". The outline used was a serial and simple distribution with controls and six replies. In this way was known the best treatment and it was "Dalapen" 21.3 Kg/ha. because the channel stayed that free of species during 55 days. In other channel but in the same trial was taken samples of water after it had been made applications over it in order to try with rice plants sown in plot the herbicides phytotoxicity when it is dilued into irrigation water phytotoxicity over the crops. This showed that triazines used in it are phytotoxic and others treatment do not have phytotoxicity but also was confirmed that application pre-seeding will cause the less damages over rice. All we had explained before showed us that this way of application will be promising to weed control in channels. The product had been applicated in recuest dosage over plot crops and we made treatments pre-seeding and post-seeding. So we reached the explained results.
