Suitable for use through any kind of foam generator to mark the edges of spray boom or other application patterns. Our Marker Foam has proven itself over many years use, to be highly reliable, stable and long lasting on the ground. The high adhesive factor resists wind movement on plants or bare ground. To use mix one litre of foam concentrate in 100 litres of very clean water (preferably rain water). With a suitable foam generator, ground speeds up to 20kph are still effective. Foam must always be used freshly mixed.
