Monterey LG1130 Mark-It Blue Spray Solution Colorant Chemical Marker Dye for Insecticide, Herbicide, and Fungicide, 8 oz

WORKS AS ADVERTISED

Used to help mark where i was sprayej g werd killer in my yard. Worked great!

This is an awesome product. Very concentrated,you will use very little.

You do not need to use as much as it says. You can use less than half as much as recommended and easily see your progress. Stains clothes and skin for a day or two.

A milder form of machinists' bluing. Try not to get it on your clothes or person. I diluted it according to the directions in a tank with diluted Tenacity crabgrass killer. It turned the mixture blue. However, I wasn't always sure I was seeing it against the dark green background of the healthier grass. Next time I'll probably use a slightly stronger mix.

Haven't had a chance to use it yet, as the weather in Illinois is still fairly cold, but I have no reason to expect it won't work well. Will be using it in combination with herbicides to treat Creeping Charly.

This works good to mark the places you spray. That way you can tell where you sprayed and where you still need to spray

Monterey works very good. I used 2ozs for three gal of spray. Needs a cap to pour it out

The dye did not help in seeing where the insecticide was sprayed.

Just did not work! This was to do one thing-show where, in the yard, you sprayed. Could not differentiate between just sprayed and where I had not sprayed.
