Herbicide mixtures are commonly used in agriculture to broaden the spectrum of weed control. The interactions or the combinations may be desirable or undesirable. Acetachlor at 150g/ha applied and ready mix application of anilofos and ethoxysulfuron at 780 g/ha provide effective control of weeds with higher grain yield. Tank mix application of metribuzin with isoproturon at 1.0 kg/ha, clodinofop (60g/ha) and fenoxyprop (120g/ha) applied at 3 leaf stage marginally increase the mortality against the resistant biotypes and susceptible biotypes of Phalaris minor with the corresponding increase in the dose of metribuzin. Tank mixing of MON 12000, CGA 152005 with atrazine or bentazon reduces the weed control of these post-emergence herbicides, in controlling velvetleaf. Chlorimuron is compatible with glyphosate, but aciflurofen antogonise glyphosate activity. Thus the interaction effect of herbicide molecule differed.
