Spectrum® Plus and Spectrum® Gold - two new products for weed control in maize

Abstract

With the introduction of Spectrum® Plus and Spectrum® Gold two new broad spectrum herbicides for pre- and post-emergence application in maize will be available. Their weed spectrum covers warm season grasses, annual meadowgrass and most annual broadleaved weeds. They can be used either alone or in sequence or tankmix with predominantly foliar herbicides. Spectrum® Plus is a premix of dimethenamid-P and pendimethalin. It is especially effective against late germinating warm season grasses and broadleaved species due to its long lasting soil activity. It is also suitable for controlling and avoiding the development of triazine-resistant biotypes. In sequences and tankmixes with herbicides with foliar activity, Spectrum® Plus provides valuable residual activity. Spectrum® Gold contains dimethenamid-P and terbuthylazine. In addition to its residual activity it is also active against larger broadleaved weeds through foliar uptake. It is also an ideal partner for tankmixes with 4-HPPDinhibitors like topramezone due to synergistic effects. Both products have been proven to show very good crop tolerance in pre- and post-emergence either alone or in combination with other herbicides.
