(Active substances: iodosulfuron and amidosulfuron)
Chekker is our unique formulation that provides excellent control of cleavers and a wide range of broad-leaved weeds in cereals including winter wheat, winter barley, spring wheat, spring barley, rye and triticale.
Chekker provides superior control of cleavers, particularly in cool, early spring conditions. It has flexible timing, from early spring right up to flower bud stage, and flexible dose rates to suit individual weed situations. Chekker can be used in all cereal crops except oats and its water-dispersible granule formulation makes it easy to use.
For the best results apply Chekker during warm weather, when the soil is moist and the weeds are actively growing. Levels of control can be reduced in poor growing conditions. Chekker can be applied after 1st February from two-leaf stage (GS 12) right up to GS 51, before the first spikelet of inflorescence is just visible. To reduce the risk of resistance, application should be made to young, actively-growing weeds.
Chekker can be used in sequence on winter wheat after an autumn-applied Atlantis WG.
In spring, Chekker can be used in tank-mix or in sequence with Atlantis WG, Hatra, Horus, Othello or Pacifica at the 400g/ha rate only.
