## Description

desertcart.com: Blue Spray Marker - (8 Ounces) - Weed Spray Dye, Herbicide Dye, Fertilizer Marking Dye, Turf Mark and Blue Herbicide Marker : Office Products

Review: Makes spraying weeds more effective. - Makes seeing where you have sprayed so easy. Just note that the color does go away fairly quickly. This is 2nd time we have purchased.
Review: A good product, but be careful! - This marking additive for weed spray does the job really well, and seems reasonably priced. That said, it is not specific about what it turns blue. So, while it marks sprayed weeds in the lawn really well, so does it color other surfaces, such as driveways, walks, fences, mulch, stones, etc., so avoid spraying these type of surfaces. None of this is a negative about the product….marking is what we ask it to do! Wear protective clothing, old shoes (boots would be better), rubber gloves, and Do Not mix colorant or sit the sprayer on a good surface to avoid a spillage disaster. This is a good product, just use with care.

## Features

- Easily Marks Grass and Lawns

Stains fingers, so be careful. Does not stay dark blue. Still can see it somewhat when dry. Does help when spraying.
