I recently had a question about putting Miravs, Elatus, clethodim, manganese, boron and a third foliar fertilizer all in the same tank.  Crop oil would also be needed for clethodim.  With our weather patterns there are a lot of acres for people to cover and mixing products is a reasonable approach.  We just don’t know exactly what will happen with seven things in the tank.  The actual formulation of a product can have an impact and water quality (hard or soft) is a wild card.  We want to avoid poor control and crop injury but also settling in the tank.  Also, the optimum timing for each of these products us unlikely to match up for a single application.  Use caution with putting this much in the tank at the same time.
