The Lazer Blue dye provides clear, temporary visibility of spray coverage, preventing overlap and waste, while the surfactant enhances herbicide effectiveness by improving coverage and penetration. Together, they ensure precise, efficient, and eco-conscious weed control for professional-grade results. ## Description Spray Pattern Indicator: Lazer Blue is a concentrated colorant designed to be used with herbicides, fungicides, pesticides, and fertilizers. Lazer indicates where application spray has been made for the most accurate coverage. The colorant will fade in time with sun and moisture. Lazer is not permanent and will not stain once diluted. Avoid contact with fabric. Lazer can be removed from skin and equipment with several washes. Directions: Add 1/2 oz.of Lazer Blue to every gallon of spray mixture. The more Lazer you use, the darker your spray pattern. POURING ADVICE- To get the smoothest pour with no mess have the FRONT label pointing towards the sky. You need to pour slowly and closely to your container in a controlled manner. Have both hands on the bottle and allow air flow to enter the spout as your pouring, DO NOT attempt to quickly dump this product in your sprayer or spraying equipment. Slow and steady while pouring this, allow airflow to enter the spout as if you were pouring gasoline. Following these steps will prevent messes and allow you to spend more time spraying and less time cleaning! Cleanup- Mix bleach with water and spray onto the dye, it will clear the dye like a magic trick. Make sure you ventilate the area as bleach can give off a strong smell. Surfactant: Get the best results from your herbicides, fungicides, and algaecides by using a surfactant. Surfactants help stick your chemical herbicides, fungicides, and algaecides to the plant. This product will also break down the waxy coating on weeds to allow more effective penetration of weed killers. Liquid Harvest Surfactant is available in three sizes: 8 oz, 16oz, and Quart. Liquid Harvest works great with Lawn and garden chemicals Review: Great to use when you want to know where you sprayed - I used this to spray my yard for pests, this is to know where I did and did not reach while spraying. Easy enough to use, covers fairly well, but make sure to wear skin and eye protection or you'll end up as blue as your yard. Review: They worked. - Used both the blue indicator and surfactant with a B-GON crabgrass killer according to the label. The sprayed area remained blue for a few days which was great. All weeds died after a few days. So apparently the surfactant worked as well. ## Features - Both products are 8 ounces - Get the most out of you spray solutions by using our Liquid Harvest spray marker and surfactant - Liquid Harvest Lazer Blue is a perfect weed spray dye for all lawn and garden spray solutions - Liquid Harvest Surfactant will Increase product coverage, product penetration, and product effectiveness by sticking your chemicals to the plant.

Easy enough to use, covers fairly well, but make sure to wear skin and eye protection or you'll end up as blue as your yard. ### ⭐⭐⭐⭐⭐ They worked. *by P***A on September 12, 2024* Used both the blue indicator and surfactant with a B-GON crabgrass killer according to the label. The sprayed area remained blue for a few days which was great. All weeds died after a few days. So apparently the surfactant worked as well. ### ⭐⭐⭐⭐⭐ Must have for lawn care... *by M***R on April 27, 2024* Didn't know how useful this stuff is until I tried it. It takes the guess work out of spraying a area... the surfactant holds the products on the plant leaf longer to absorb the product...thus making it more effective. ## Frequently Bought Together - Liquid Harvest Lazer Blue Concentrate Spray Pattern Indicator 8 Ounce & Liquid Harvest Surfactant for Herbicides Non-Ionic 8 Ounce - Atticus Torocity Herbicide (8oz) - (Compare to Tenacity) - Mesotrione Concentrate - Selective Weed Killer for Lawns and Turf Grasses - Pre and Post Emergent Control - Atticus Empero Nutsedge Killer (1.33 oz) Halosulfuron-Methyl 75% Turf Herbicide - (Compare to The Leading Brand) - Kills Nut Grass in Established Lawns, Ornamental Turfgrass, & Landscape Areas --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.no/products/217911757-liquid-harvest-lazer-blue-concentrate-spray-pattern-indicator-8-ounce](https://www.desertcart.no/products/217911757-liquid-harvest-lazer-blue-concentrate-spray-pattern-indicator-8-ounce) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
