Hydra Trak-It Green dye is a weed-killer spray indicator dye which can be used with pesticides and herbicides. When combined with a chemical spray solution, it helps to identify the sprayed & unsprayed area, which eliminates the wastage of costly chemicals by preventing a double application or any misses. In addition, it shows drift and improper application along with making visible blocked nozzles and leaks in spray equipment.

Hydra Trak-It Green dye is specially formulated to be added to the liquid spraying solution. It is a highly concentrated visible dye but stays only for a short term after application. The treated area remains green for a few days depending on the surface it's used on. The colour starts to fade naturally either in sunlight or rain within 48hrs.

This product is non-toxic, environmentally friendly, completely soluble and safe to use with all water-based systems.

This product really helped to see where I had sprayed. It gave the grass a nice green colour as well that lasted about a week. I definitely recommend this product to any lawn lover.

Good coverage

Worked as intended and had good coverage. Make sure to wear gloves when handling the dye though. It rinses out of the pump srayer easy enough with running water.
