BLUE MARKER DYE Clearly identifies what areas have been sprayed, eliminating double applications and preventing over application of herbicide.

 BLUE MARKER DYE is a spray pattern indicator dye which aids operators to ensure correct application of spray solutions such as pesticides. It highlights clearly where there is overlapping, misses and also indicates any blocked nozzles during the spraying process.  BLUE MARKER DYE  is based on an environmentally friendly benign food grade dye technology.

 BLUE MARKER DYE, once applied, breaks down naturally within 48 hours either by rainfall or sunlight degradation.
