Best Use

Timing and Optimum Conditions

Apply in a period of active growth before the grass reaches 25cm high in the spring or up to 25cm after cutting.

In dense crops, use a higher volume of water. Weeds yellowing, under stress or damaged will be less well controlled. Avoid grassland under stress especially drought, water logging, disease or insect attack. Topping Soft Rush in late spring
prior to seed formation weakens the plant, which then has to regrow. If the regrowth is treated when the Soft Rush is about 15cm tallbetter control will be achieved. Good fielddrainage and management of acidity will also help eradicate this weed.


Clovers or other legumes present in the sward will be severely checked, but will eventually recover. Livestock must be kept out of treated areas for at least two weeks and until poisonous weed such as Ragwort have died and become unpalatable.
