Kelvin Top is a systemic herbicide that is rapidly distributed in plants. The growth of weeds ceases within a short interval of application of only 6 hours. The activity begins in the young growth peaks, which change color to yellow, become chronotropic within a few days. The treated weeds become brownish, and their deaths occur after one or three weeks after application, depending on species and environmental conditions. corn is tolerant to nicosulfuron because it is rapidly metabolised to a form that is not active on its own ALS. The best results are obtained when Kelvin Top is applied to active growth weeds, and adequate humidity is required to ensure an optimal level of activity.
Mode of action:
Apply post-emergence when corn plants have 4-6 leaves, annual grass weeds are in the phase of 1-3 leaves to bite, perennial grasses are 10-15 cm, cost 15-20 cm, and dicotyledonous weeds either small (2 leaves).
