How long does it take for TVC to take effect after spraying?

Answer:

TVC controls vegetation by absorption through leaves, stems, and roots, from which it is translocated throughout the plant, where it accumulates in rapidly-growing meristematic tissue. Treated plants stop growing soon after treatment. Chlorosis (yellowing of plant tissue) first appears in the newest leaves and necrosis spreads from this point. In perennials, TVC is translocated into and kills underground storage tissues to prevent regrowth. Chlorosis and tissue necrosis may not be apparent in some plant species until two weeks after application. Complete kill of plants may not occur for several weeks.
