Review: Totalement inutile ! - J'ai testé ce produit sur différentes mauvaises herbes de différentes tailles et .... excepté le fait que ça est donné une couleur bleu au sol ca n'a absolument rien fait !
Review: Outstanding Spray Pattern Indicator – Clear, Consistent, and Highly Effective - I recently purchased the Liquid Harvest Laser Blue Concentrated Spray Pattern Indicator (32 oz), and I couldn't be more impressed. The product quality is exceptional—the concentrated formula is clearly manufactured with careful attention to consistency and performance. Mixing and application were quick and effortless. The concentrate dilutes easily to the proper ratio, and the spray solution worked flawlessly right out of the bottle. The bright laser blue color provides excellent contrast against foliage, making spray coverage immediately visible in the field. Performance-wise, this indicator delivers every time. It provides smooth, even color distribution and produces consistent, highly visible marking that helps eliminate gaps and overspray. The dye maintains its visibility throughout the application without fading prematurely, ensuring accurate coverage tracking from start to finish. The overall effectiveness and value exceeded my expectations, especially for the price. The 32-ounce concentrated formula goes a long way, making it an economical choice for both small-scale and large-area applications. I'd highly recommend Liquid Harvest Laser Blue to anyone looking to improve the accuracy and efficiency of their spraying operations—whether you're applying herbicides, pesticides, fertilizers, or other liquid treatments. It's an essential tool for precision agriculture and lawn care professionals.

### ⭐⭐⭐⭐⭐ Excellent Biodegradable Dye
*by R***N on 14 September 2025*

This dye works perfectly for tight-line spraying, complete coverage, and spot application as needed. Yes, it can be messy to use; however, I transfer the dye into an easy-to-use container (Tattoo Squeeze Bottle) by using a funnel. The bottle doesn't leak, and it doesn't spill when handled; it requires a gentle squeeze. I squeeze the exact amount into the EISCO Plastic Graduated Cylinder. No mess at all! Both the Tattoo and EISCO are available on Amazon. The picture is seen below.
