This site was seeded with the culti-trash seeder which sowed the crop greater than 10 cm deep. Due to the inversion of metribuzin treated soil onto the seed, the deep seeding and short coleoptile of Blade, all IBS treatments were reduced in yield with the exception of Lexone + Logran.
Blade showed good tolerance to metribuzin at this site and it is was only at the 400 g of the Lexone/ha rate the yield reductions were obtained with the IAS and Z12-13 treatments.
Blade wheat tolerace to metribuzin was good both IBS and IAS, but decreased with increasing rate of Lexone at the Z12-13 timing.
