A wetting agent for use with weed killer. It increases the surface contact area between spray droplets and the leaf surfaces of weeds, enhancing weedkiller uptake. Weeds that are normally difficult to control with weed killer due to waxy leaf surfaces (such as gorse and bracken) are effectively controlled with the addition of pulse(r).Features pulse(r) has been developed and proven under new zealand conditions. The only wetting agent recommended for use with roundup(r).Controls gorse, bracken, blackberry, buddleia, cutty grass, willow, broom, pampas, clematis and other difficult weeds.Ingredients pulse contains an organo-silicone co polymer penetrant and surface active agent. Directions for use mix 2 ml of pulse per litre of roundup. Over application of pulse penetrant may lead to reduced results, due to run-off.
