Abstract

According to the result of field trial, it is showed that the formulation product of tribenuron-methyl+MCPA-Na+carfentrazone-ethyl 55% WP can control effectively broad-leaved weeds in the wheat field at the level of 600 to 700 g/hm2. Fiftieth days after spraying, the control efficacy to individual plant and fresh weight can be reached 96.9% to 99.1% and 99.3% to 99.8% respectively for the broad-leaved weeds, such as Galium aparine L var tenerun Rchb, Capsella bursa-pastoris (L) medic, Vicia satira L and Hemistepta lyrata bunge .It is safe to wheat and the yield of wheat increases 15.91% to 18.72%.
