Description
Weed Force Rhodamine Red Spray Marker Dye is a high-strength liquid marking agent. It provides a clear visual track for agricultural chemical applications. Because it is formulated with 150 g/L of the active constituent Rhodamine B, this dye allows operators to identify treated foliage easily. Consequently, this prevents costly double-spraying or missed sections in the field. Therefore, it is an essential tool for landholders and contractors seeking precision when applying herbicides, pesticides, and liquid fertilisers.
Furthermore, the dye is designed for dual-purpose use. Specifically, it acts as a direct spray marker on plants and a colouring agent for foam marker systems. When added to white foam markers, it converts the output to a high-visibility pink. As a result, it is much easier to track swaths in challenging terrain or low-light conditions. Ultimately, this product improves application efficacy and reduces wastage in broadacre cropping and pasture management.
What is the primary benefit of using Weed Force Rhodamine Red?
This marker dye eliminates guesswork by providing an immediate, vibrant red visual reference. Moreover, by identifying exactly where product has landed, landholders avoid overlapping swaths. In addition to saving on chemical costs, this reduces the environmental footprint of the application.
Is it compatible with all herbicide types?
This marker is suitable for both liquid and powder herbicide formulations. However, technical precision is required when mixing with amine-based products like 2,4-D Amine or MCPA. In these cases, you must mix the dye with water before adding the herbicide to the tank. Consequently, this ensures the stability and efficacy of the final mixture.
Can the dye damage non-target surfaces?
Yes, Weed Force Rhodamine Red Spray Marker Dye is dye-fast on most materials. Therefore, operators must prevent spray drift from contacting vehicle paintwork or other valuable equipment. Because the dye is highly concentrated, any resulting red stains can be permanent.
