BASF Turf Mark Blue Spray Marking & Pattern Indicator Dye for Weed, Fertilizer & Herbicide Application on Grass and Lawns, Non-permanent 32 oz

Don’t need a lot to do what you need !!!!!!

The directions call for 2-3 ounces of product for 3 gallons of water. I mixed the product at 2 ounces and it works great. My grass/weeds are pretty yellow as you can see in the picture, so it does stand out pretty good. If your grass is a lot greener you might have to go with a bit more in the water.I works great on the grass, but wear rubber gloves when mixing it unless you enjoy being mistaken for part Smurf. You can see my hand in the picture and that is after scrubbing with soap and water. It also will stain concrete. It will also stain dog feet! No, there was no chemical in the water when I did any of this, it was just the Blue Turf Mark. I just got the sprayer hooked up to my new lawn tractor and was experimenting with the color, flow rate, etc. I found that it also stains the bare feet of my 4 year old grandson!All in all I'm quite pleased with it. Now that I know how it sticks to non-grass surfaces, I'll be more careful in the future. I will definitely purchase more when I need it.

I had heard this stuff gets everywhere. I wore gloves and didn’t get a drop on my hands or arms, but I didn’t think about my feet! The color is good, and there was plenty for an 18,000 sf lawn. I wish the container was a bit bigger. I’d order this product again.

Measuring is fantastic. This type of container is the only way to go if you can get it. Used this to mark for herbicides on my lawn. Not as dark as I expected even mixing heavy. I found that at a distance I could see it, kinda like a shadow, but up close looking for the overlap not so much. Still worth using. This was the case when spraying the entire lawn with pre-emergent. For spot use the color stands out much better. I had no issues with clean up. Overspray on concrete & synthetic fence (not sure of the material but not wood) rinsed right off. Got quite a bit on my thumb when my rubber glove tore, cleaned off pretty good using a fingernail brush and aggressive cleaning, completely off my thumb on the next day. I use this with: MSO surfactant, 2,4D, XLR8, and Dimension. Mixed fine with any mixing combinations I needed at the time. I have a 2gal backpack sprayer and no issues at all with spray pattern. I did start every mix with about 2/3 water and blue dye first, I always add the MSO last. I’m not sure if it matters but some info out there suggests mixing in that order.

Easy to use, easy to mix, easy to measure and does not cause permanent stain. Was off my bermuda grass within 24hrs.It comes with a label with all the directions and first aid information.Measurement is on ml or oz for a proper dosign regardless if you use metric (like me) or imperial.Recommended!

The ink is bright and washer away without residue on concrete or stone. I use it with my garden sprayer.

I thought this might be a 'luxury' I didn't need. I've been spraying for years without it. Well, for gross spraying - down the edges of the rural driveway and some general areas, I can still do without it. But when spraying "Cat's Claw" vine in the woods around my house; when trying to get rid of all the bermuda grass when preparing a new planting bed - or for anything else that requires some finesse and accuracy, this stuff REALLY helps. I find for most of my stuff I can use it about 1/2 strength (& sometimes 1/4) & save a few bucks. It shows easily on bare ground / dry & dead grass / driveway rocks / and concrete (edge). But it also easily washes off in a day or two of sun and/or rain. Sometimes within a few hours it's hard (at 1/2 strength) to tell where I've sprayed. If vegetation is lush and you're only wanting to spray part of it - use more. It's harder to see on just green vegetation than on surrounding ground, but even at 1/2 strength you can see if you look. I won't use it ALL the time, but I will have it available ALL the time for when it's most helpful.

Used this for a lawn spray indicator. First and foremost, having the ability to measure the product with the little squeeze chamber is critical for a dye like this, and if you look at other indicator products, the most common negative is from staining issues. With this product, I had no issues spilling it on myself, my clothes, or my driveway. Mixed well with a cocktail of ingredients, and provide a nice blue that was definitely easy to see on my mostly-dormant grass. It was almost nice, because the next day it had faded in a bit and combined with the lime green grass just waking up, it almost looked like an early summer green just coming out of winter. Anyway, it does the job you want it to. No, it won't make your lawn look like a smurf, but it's enough of an indicator to show where the spray is landing. Decent value for the amount of product, and definitely the easiest to use of everything available out there.
