Hi-Light is a temporary colorant used for effectively marking spray applications. Hi-Light improves applicator safety by providing the applicator with an economical marker for broadcast, backpack, or general spot treatment. It can be used with spot-gun, hand equipment, small broadcast equipment, boom-jet, and other spray application equipment. Hi-Light washes off equipment, clothing and skin with soap and water.

By adding Hi-Light to spraying systems, spray application personnel are able to uniformly apply pesticides and liquid fertilizers. Hi-Light is compatible with most chemical compounds and is used in applications ranging from broadcasting of soil sterilants to spot treating with brush control products.
